Concrete Mixes FAQs

 

We suggest concrete mixes depending on application requirements and ground conditions. Contact a member of our expert team to discuss the details of your project and we will be able to suggest the best concrete mix to suit your needs.

This will depend totally on the size of your lay site. Use our useful concrete volume calculator to find out how much concrete mix you’ll require for your project.

If you do not have a credit account with us, then our preferred method of payment is by credit or debit card.

Cure time will depend on a number of factors, such as the type of concrete mix being used and external weather conditions, however, you should have at least between 1-2 hours in which to lay the mix. We will be able to advise you more accurately once we have more details, so don’t hesitate to contact us. 

All of our concrete delivery vehicles come with chutes that can deliver ready mix concrete up to approximately 2.4m away from the rear of the vehicle and 1.2m from the side. If your lay site has restricted access that would make delivery by normal means impossible, then one of our concrete pumps for hire would be able to transport the concrete to your lay site with ease.

The minimum width required for our vehicles is 2.7m or 8ft 10 inches. If you believe that entry to your site would be particularly tricky for one of our delivery vehicles, then we would be happy to arrange for one of our team to inspect your site beforehand. You can also request delivery through our mini pump, which is perfect for accessing lay sites that are too hard to navigate for larger vehicles.

If you wish to move the concrete mix yourself i.e. with a wheelbarrow or dump truck, then you should request your ready mix concrete at a lower slump. This will mean that it is drier and therefore easier to transport manually. Please let us know in advance if you wish for our concrete mixers to offload directly into your wheelbarrow, so that we can schedule appropriately.

Our delivery trucks remain on site for an allotted time of 30 minutes. If you require the delivery truck for longer than this time, then this may incur you a waiting time charge.

Yes – without tamping, vibrating, or compacting, air pockets would remain trapped inside the wet concrete mix. These air pockets could seriously weaken the overall structure of the concrete, making it weaker and less durable than it would be if the concrete was made denser. When reinforcing metal is used, this method also ensures that the concrete best bonds to the metal.

Concrete mixes can be harmful if not handled correctly. That is why we always suggest wearing the appropriate safety gear and following these guidelines when handling our ready mix concrete or liquid screed:

  • Fresh concrete or screed can cause burns to the skin and eyes, so wear protective clothing (impervious boots, goggles, gloves, long sleeves and trousers)
  • If concrete makes contact with your skin or eye, then wash it off thoroughly or rinse from your eye immediately.
  • Do not swallow. If any concrete mix is ingested, seek immediate medical advice.
  • Once finished, remove your clothing and wash it thoroughly before reuse.

     

We have a large fleet of delivery vehicles in a range of sizes and capacities (length + width + height = capacity):
6.5m + 2.5m + 4m = 4m3
7.5m + 2.5m + 4m = 6m3
8.7m + 2.5m + 4m = 7.5m3

Concrete vs Steel: Which Material Is Better to Build With?
23rd October 2025

Every construction project begins with one key question: which material delivers the best results? Across the South West and South Wales, that choice often comes down to concrete vs steel. Both have played a key role in the UK’s built environment for decades. Each offers unique strengths that influence cost, performance, and sustainability.

Concrete provides high compressive strength and strong thermal efficiency, creating stable, energy-efficient buildings. Steel provides strong tensile strength and precise design. This makes it perfect for long-span and high-rise structures. The Institution of Civil Engineers (ICE) states that much of today’s infrastructure relies on reinforced concrete. This combination of both materials balances flexibility and durability. However, concrete’s affordability, local sourcing, and long lifespan make it the most practical option for most UK builds.

We offer ready-mix concrete that meets British Standards (BS 8500-2) and deliver it quickly throughout the region.

How Do Concrete & Steel Compare in Construction?

ICE identifies strength and behaviour under load as the main difference between concrete and steel. Concrete excels when compressed, so it’s perfect for footings, walls, and load-bearing slabs. Steel excels in tension, resisting bending or stretching. This is an excellent advantage for high-rise buildings and long-span structures such as bridges.

When used together in reinforced concrete, the materials complement one another. The steel absorbs tensile forces, while the concrete distributes compressive loads. This creates a strong and balanced structure that works well for many commercial and home projects in the UK.

Concrete provides substantial thermal performance benefits. It helps keep indoor temperatures stable and lowers heating demand. The Building Research Establishment (BRE) explains that concrete’s thermal mass can help lessen peak energy loads. It does this by absorbing heat and slowly releasing it. This process boosts comfort and efficiency in buildings. Steel can achieve similar results but often requires added insulation to match concrete’s performance.

To enhance supply and speed up delivery, we operate various regional plants. These plants are set up for fast batching and local delivery, and you can learn more via our concrete plants page.

What Costs More to Build With Concrete or Steel?

For most UK projects, concrete continues to offer greater cost stability than steel. Data from the House of Commons shows that steel prices are more volatile. Its price is influenced by energy costs and global supply chains, hence the need for the government’s steel strategy. Concrete, on the other hand, is primarily produced and sourced locally. This helps maintain predictable pricing and availability.

Steel structures help shorten construction time through prefabrication. However, the increased costs of fabrication and transport can eat into those savings. Concrete is affordable, available, and easy to place. This makes it the top choice for home and business projects in the South West.

Key advantages of concrete for cost control:

  • Concrete is sourced locally, reducing transport costs and environmental impact.
  • Each mix is precision-batched to minimise waste and improve efficiency.
  • LGW's regional plants support reliable delivery schedules.

As part of The LGW Group, we offer consistent pricing and dependable supply across the South West. Our team also provides concrete pumping services. These help streamline on-site delivery and reduce labour costs by enabling faster, cleaner pours.

Why Concrete Leads in Sustainability & Longevity

The key difference in sustainability between concrete and steel lies in how they perform throughout their lifecycles. Steel is fully recyclable, but its production is energy-intensive, requiring temperatures of over 1,500°C. Concrete can use recycled aggregates and low-carbon cement substitutes. This helps reduce embodied carbon while still maintaining strong performance.

The UK Green Building Council (UKGBC) says the construction sector needs to cut whole-life emissions. This can be achieved by improving material efficiency and reducing transport miles. We help achieve this goal by using local batching and delivery. This reduces haulage distances and lowers fuel use across the South West.

Sustainable advantages of concrete include:

  • Using locally sourced materials reduces transport emissions.
  • High thermal efficiency reduces operational energy use.
  • Long service life with minimal maintenance.

Concrete’s durability also supports sustainability by extending the lifespan of structures. The Building Research Establishment (BRE) says reinforced concrete can last over 100 years. That is, if it is mixed and properly looked after. In coastal or humid areas, steel parts usually need protective coatings or galvanising to avoid corrosion. Maintenance concrete often skips this step.

This long-term resilience plays a key role in the UK’s Net Zero Strategy. It focuses on using low-maintenance, low-emission building materials for sustainable construction.

Top 3 Reasons Concrete Is Still the Core of Modern Construction

Steel is key to structural engineering, yet concrete remains the foundation of most construction in the UK. Its performance, versatility, and local availability make it a reliable choice for all types of projects. This includes everything from small home extensions to large commercial developments.

1. Versatility for Every Project

Concrete can be poured, shaped, and finished to meet almost any specification. It supports decorative architectural work, large-scale structural elements, and even polished interiors. We supply liquid screed for smooth and efficient flooring. It meets current performance standards.

2. Long-Term Durability

Concrete resists fire, weather, and corrosion, maintaining its structural integrity for decades. High-density concrete is a preferred material for safety and longevity in UK building standards. For domestic use, we provide tailored mixes for driveways and shed bases to ensure reliable strength and finish.

3. Cost Stability & Efficiency

Concrete remains a stable option for costs. This is thanks to its local sourcing and efficient production methods. We provide accurate batching and flexible delivery from various regional plants. This helps contractors reduce waste and stay on track. Materials like bulk bag aggregates and gravels enhance on-site efficiency and aid in resource planning.

Concrete is versatile, resilient, and affordable. These qualities make it a top choice for builders, developers, and homeowners in the South West. This approach supports lasting value and sustainable growth in the region.

Your Project Deserves Concrete Confidence

In the concrete vs steel debate, both materials remain vital to construction. However, concrete offers the best balance of strength, cost stability, and sustainability. Its flexibility and local sourcing make it a reliable choice for both small foundations and large commercial builds.

How to Calculate Concrete Pump Capacity for Your Project
20th October 2025

Calculating the right concrete pump capacity is essential for staying on budget and on schedule. After all, choosing the right pump size is key for any project, big or small. It helps deliver materials efficiently, avoids delays, and reduces waste. Inaccurate pump capacity calculations can result in running out of concrete or over-ordering. Both situations are expensive and time-consuming.

In this guide, we’ll walk you through the steps to calculate the concrete pump capacity for your project. However, we also have our trusty concrete volume calculator, should you ever need it.

With the right approach, you can avoid complications, save on material costs, and ensure your concrete is delivered on time, every time.

Understanding Concrete Pump Capacity

Concrete pump capacity refers to the volume of concrete a pump can deliver per hour, typically measured in cubic meters per hour (m³/hr). The required capacity for your project depends on several factors, including:

  • Project size
  • Delivery distance
  • And height

For example, a small driveway pour uses much less pump capacity than a large commercial foundation. Grasping these factors helps you select the right pump. This way, you can avoid delays and inefficiencies. To give some context, England generated 63.0 million tonnes of non-hazardous construction and demolition waste in 2022. Inadequate project planning contributes significantly to material overruns and disposal costs.

To get the right concrete pump, understanding these variables and knowing how to calculate the required pump size is crucial.

How to Calculate Concrete Pump Capacity for Your Project

To determine the pump capacity you need, follow these steps:

Start by calculating the total concrete volume for your project. Use the formula:

Volume = Length × Width × Depth

For example, if you’re working on a driveway that is 6m long, 3m wide, and 0.15m deep, the calculation would be: Volume = 6m × 3m × 0.15m = 2.7m³. Concrete is sold in cubic meters (m³), so in this case, you will need 2.7m³ of concrete.

Estimate how long the pour will take. For a typical residential project, such as a driveway, it may take 2 hours. To calculate the required pump capacity, divide the total volume by the pour time:

Required Pump Capacity = Total Volume ÷ Duration

e.g. 2.7m³ ÷ 2 hours = 1.35 m³/hr pump capacity

Best practice suggests adding an extra 10% to your volume estimate. This helps cover spillage, slab depth differences, and site conditions. For a 2.7m³ pour, this brings your total to approximately 2.97m³, ensuring you don’t run short mid-pour.

Why This Matters

In the UK, ready-mix concrete is typically ordered and supplied by volume in cubic metres. Most suppliers offer quantities from 1m³ upwards in 0.5m³ increments. Calculating your pump capacity in advance ensures you select the right pump for your project’s specific needs. No matter whether it’s the volume of concrete, height of the pour, or distance the concrete needs to be transported.

Choosing the Right Concrete Pump for Your Project

Once you’ve determined the required pump capacity, the next step is selecting the appropriate concrete pump for your project. There are two primary types of concrete pumps: boom pumps and line pumps. Each has its advantages, depending on the project’s size, the site layout, and how far the concrete needs to travel.

Boom Pumps

These pumps work well for larger projects, including high-rise buildings and multi-storey foundations. They use a hydraulic arm called the “boom” to reach farther. This lets them deliver concrete both vertically and across long distances. Boom pumps can quickly supply large volumes of concrete. They work well for complex projects, especially where access is tight or the terrain is challenging. Modern boom pumps can reach heights of over 60 metres, making them vital for high-rise construction. In such circumstances, ground-level delivery isn’t always practical.

Commercial Example: For pouring concrete in multi-storey buildings or bridges, a boom pump is ideal. It offers excellent reach and high output capacity.

Line Pumps

Line pumps use flexible hoses to pump concrete, making them ideal for smaller projects or sites with restricted access. They are more compact and versatile, able to pump concrete into smaller spaces and difficult-to-reach areas. Line pumps are commonly used for driveways, foundations, and slabs.

Residential Example: For a driveway pour, a line pump works well. It moves concrete at about 1m³ per minute. This makes it a cost-effective and efficient choice.

Choosing the right pump depends on factors such as project size, accessibility, and the volume of concrete required. If you’re unsure which type suits your project, our professional team can help guide you towards the best choice based on your specific needs.

Saves Time & Money with Accurate Concrete Pump Capacity

Accurately calculating concrete pump capacity is crucial to keeping your project on track. Choose the right pump by considering factors such as concrete volume, pour time, and site access. This helps you avoid delays, wasted material, and extra costs.

No matter if it’s a small home pour or a big commercial project, getting the calculation right makes things easier and boosts efficiency. Wright Readymix offers a full range of concrete pumps suited for all projects. Our experienced team is here to help you select the ideal pump for your needs.

How to Choose the Right Concrete Grades for Your Project
29th September 2025

Choosing the right concrete grade is key for any project, whether it’s driveways or commercial foundations. Concrete grades indicate how much pressure the mix can withstand. This makes them essential for ensuring your structure’s strength and durability. But with so many grades to choose from, how do you know which one is right for your specific project?

Using the wrong grade of concrete can lead to costly repairs, and either a weaker mix will crack, or an overly strong mix will cost more than necessary. This guide details the different concrete grades. It will help you find the best mix for your DIY patio, shed base, extension foundations, or any other project.

By the end, you’ll have the knowledge you need to make the right choice, saving time and money while ensuring your project stands the test of time.

What Are Concrete Grades & Why Do They Matter?

Concrete grades are a measure of the mix’s compressive strength and indicate how much weight the concrete can bear after curing. In the UK, concrete grades are standardised under BS 8500, which complements the European standard BS EN 206.

The grades are typically represented with a “C” followed by a number, such as C20. The number shows the compressive strength from standard cube tests in BS EN 12390-3. It indicates how much pressure the concrete can withstand after 28 days of curing and is measured in Newtons per square millimetre (N/mm²).

So, why does this matter for your project?

Concrete forms the base for many structures, such as driveways, foundations, and industrial floors. The grade you select ensures your structure remains stable and durable, performing as expected over time. Choosing the right grade is crucial. If the concrete isn’t strong enough, it could fail under load; if it’s too strong, you’re unnecessarily inflating your budget.

With our broad experience in South West England and South Wales, we’ll provide you with the right concrete solution every time.

How to Choose the Right Concrete Grade for Your Project

What Is the Purpose of The Concrete?

Start by considering the purpose of the concrete. Is it for a light garden path or a heavy-duty foundation? For decorative projects like patios or walkways, lower grades like C10 or C15 will do the job. For foundations or roads that bear significant loads, you’ll need C25, C30, or C40, which can handle higher pressure.

What’s the Weight the Concrete Needs to Support?

Think about the load the concrete will bear. A garage floor or driveway will need a more potent concrete mix like C25 or C30 to handle vehicle traffic. For light uses such as garden paths or patios, C10 concrete will suffice without overcomplicating the cost.

What Environmental or Ground Conditions Must Be Considered?

Concrete exposed to extreme weather or unstable ground needs more durability. If your project will deal with moisture, snow, or temperature changes, choose C30 or C35 concrete. They provide better freeze-thaw resistance. If you’re pouring on soft or unstable ground, a stronger concrete mix will offer stability and long-lasting results.

Common Concrete Grades & Their Applications

C10 Concrete

C10 concrete is great for non-load-bearing projects. It’s ideal for lightweight tasks like garden pathways, patio slabs, and decorative uses. It’s not suited for areas with heavy traffic or structural demands, but it works well for simple landscaping and DIY jobs.

C20 Concrete

C20 is often used for driveways, garage floors, and small foundations. It provides a strong yet affordable option. This grade is versatile and suitable for residential projects that won’t experience significant loads or wear and tear. It also works well for internal floor slabs.

C25 Concrete

A versatile grade, C25 is often used in foundations, footings, and reinforced bases. It’s well-suited for medium-sized residential and commercial projects. It can withstand moderate loads and is commonly used for driveways, patios, and industrial floors exposed to some weight.

C30 Concrete

The go-to grade for heavy-duty pavements, industrial floors, and foundations exposed to high traffic or large vehicles. It’s often used in road construction, in commercial buildings, and in areas that need strong durability and resistance to freeze-thaw cycles.

C40 Concrete

C40 is the most potent mix. It’s made for busy commercial and industrial use, like structural foundations and heavy-load areas. It’s perfect for projects that need high durability. This includes highways, heavy-duty pavements, and structural beams in industrial areas.

Key Considerations When Selecting Concrete Grades

Project Type & Load-Bearing Requirements

The type of project you’re working on plays a significant role in selecting the right concrete grade. C10 or C15 concrete might be sufficient for light DIY projects like pathways or garden patios. For heavier projects, like garage foundations or industrial floors, grades such as C25, C30, or C40 are crucial. They can handle the extra load and offer the needed durability.

Environmental Exposure

Concrete that faces harsh conditions, such as extreme weather, moisture, or freeze-thaw cycles, needs to be more durable. C30 and C35 grades are perfect for outdoor use, such as driveways, pavements, and roads. They resist freeze-thaw cycles and handle changing temperatures and moisture well.

Curing & Mixing Ratios

The mix ratio (cement, water, and aggregate) directly affects the final strength of the concrete. Higher-grade mixes typically require less water and more cement to ensure a denser, stronger product. For DIY projects and commercial builds, using the correct ratio is key. It helps achieve the concrete grade’s full strength and durability.

Get the Right Concrete Grade, Save Time, & Build Strong

Choosing the right concrete grade is essential for your project’s durability and strength. Whether you’re a DIY homeowner or a contractor, the right mix ensures your structure performs reliably for years. Selecting the correct grade prevents unnecessary repairs and delays while keeping costs in check.

For most residential projects, C20 or C25 concrete offers the right balance of strength and cost. For tough jobs, like roadways or factory floors, C30 or C40 is crucial for lasting strength and performance. At Wright Readymix, we’re here to guide you in selecting the perfect concrete grade, ensuring your project stands the test of time.

What is Architectural Concrete & How is it Used in Design?
24th September 2025

Architectural concrete is a versatile material that’s bringing a whole new dimension to construction. It mixes the toughness of traditional concrete with the design freedom that architects and builders prefer. Architectural concrete adds character to any space, whether for a polished floor or an eye-catching exterior. Plus, it stands the test of time.

In this guide, we’ll show you how architectural concrete can bring your next project to life. You’ll find out what makes it special, how it's used in design, and why it’s become a favourite for both residential and commercial projects.

What Makes Architectural Concrete Unique?

Architectural concrete stands out because it’s not just used for structure; it’s crafted to make a statement. Standard concrete stays hidden in walls and foundations. In contrast, architectural concrete is made to be visible and admired.

Architects and builders love it because this material offers design flexibility with:

  • Sleek polished floors
  • Textured facades
  • And decorative features

Best of all, it can be customised in a whole range of ways, from colours and textures to finishes like exposed aggregate or polished concrete. Want something modern and clean? Done. Looking for a more rustic, industrial feel? You’ve got it. It’s that versatility that makes architectural concrete so special. It can be tailored to suit just about any style and project.

The UK construction industry is seeing more demand for flexible building materials. The government reports that concrete and cement production have risen by 2.5% month-on-month recently. This shows how the industry is shifting to materials that are strong and visually appealing. In 2022, Great Britain had around 674,000 self-employed construction workers.

How is Architectural Concrete Used in Design?

Architectural concrete appears in various projects. It can be found in residential buildings, commercial spaces, and public infrastructure. It’s a material that’s as functional as it is beautiful, making it the perfect choice when you want your designs to look great and stand the test of time.

Residential Applications

For residential projects, architectural concrete provides durability and low maintenance. This is what every homeowner wants. It's often used for driveways, walkways, and facades. The material not only works well but also boosts the property’s overall appearance.

Examples include:

  • Polished concrete floors for that sleek, modern vibe.
  • Exposed aggregate driveways offer both texture and style.
  • Textured facades that make your home’s exterior pop and stay protected for years.

Architectural concrete plays a significant role in achieving the UK’s net zero targets by 2050. It brings essential sustainability benefits to residential projects. The government’s new building rules, introduced in April 2024, focus on better energy efficiency. Concrete’s thermal mass reduces heating and cooling needs in homes. This results in lower carbon emissions for residential buildings.

Commercial Applications

In commercial settings, architectural concrete takes on a much bigger role. It’s used in everything from floors to facades and public spaces. It provides durability for high-traffic areas and design flexibility to fit any commercial style.

For instance:

  • Decorative concrete flooring that can mimic the look of expensive materials like marble without the hefty price tag.
  • Exposed aggregate facades that can make a building stand out and increase curb appeal.
  • Custom concrete furniture or architectural features that leave a lasting impression.

The UK’s architectural, engineering, and construction services market is expected to reach £11 billion by 2030. This growth comes with a compound annual growth rate of 15.5% throughout the decade. This growth is leading to more use of architectural concrete in commercial projects. Developers seek materials that are visually striking and can withstand heavy use in high-traffic areas.

Infrastructure Projects

Architectural concrete isn’t just for buildings. It’s used in infrastructure projects like bridges, highways, and street furniture. It provides the necessary strength for busy areas and offers design options that public spaces should have. Architectural concrete features in urban areas and is used for benches and light posts, as it combines style with utility.

The UK government has outlined a 10-year strategy for infrastructure investment. This significant investment is creating chances for architectural concrete in key projects. It’s suited for places like transport hubs and public buildings. Its durability and design flexibility make it ideal for high-traffic public areas.

How is Architectural Concrete Made?

Architectural concrete is created by blending specific materials. This ensures it meets the project’s structural requirements and design aims. The key difference from standard concrete is the focus on appearance, making sure it looks as good as it performs.

  • Cement: The base component that holds the mix together. White Portland cement is commonly used for its clean colour, ideal for decorative projects.
  • Aggregates: These include sand, gravel, or crushed stone. The type and size of aggregates determine the texture and finish of the concrete.
  • Colour Pigments: Added to the mix to create the desired colour for the finished product.
  • Admixtures: Special ingredients that change the properties of concrete. They make it easier to work with or help it cure faster.

The UK cement industry is putting more emphasis on sustainability. From 2024, companies must collect and report environmental data every three months. Sustainability rules are sparking new ideas in concrete admixtures and production. This shift is making lower-carbon options – like recycled steel reinforcement and sustainably sourced aggregates – the norm in architectural concrete.

Surface Finishing Techniques

Once the mix is ready, the concrete is poured into formwork (the mould used to shape it). Custom form liners can be used to create specific textures or patterns on the concrete surface, giving it its signature look.

  • Exposed Aggregate: A technique where the top layer of the concrete is removed, revealing the natural texture beneath.
  • Polished Concrete: For smooth, high-gloss finishes that are perfect for both floors and surfaces.
  • Formed Concrete: Concrete poured into custom moulds to create unique patterns and textures.

The finishing process significantly affects how the concrete looks. It’s essential to pay attention to detail to achieve the desired result.
