Our self-developed Wrightflow screed is a cement based, self-compacting and virtually self-levelling liquid screed which can be used for any internal floor.

Wrightflow screed is easy to pour and its liquid properties make for quick drying and installation. It’s especially effective when combined with underfloor heating systems, as it eliminates air pockets and therefore increases conductivity. This guarantees quick and even heat supply across the floor and makes your building more thermal efficient, saving you money.

Wrightflow screed is only suitable for use on internal floors.

Yes, as the advantages of Wrightflow liquid screed are not limited to its energy efficiency and are intended for use in all aspects of construction. The use of our liquid screed eliminates the need to seal the floor prior to laying latex, adhesive or any other cement-based product. It can also be used in wet as well as dry internal areas without degrading the screed quality.

This answer is different depending on whether the floor is bonded, unbonded, floating (commercial or domestic) or with underfloor heating. To find the solution to your particular requirements, a member of our expert team would be happy to help you.

Screed and Underfloor Heating
25th October 2021

When looking to install underfloor heating, there’s one particular type of concrete that industry professionals rely on: screed.

At Wright Minimix we have decades of experience in producing quality screed for installations of all shapes and sizes, and know very well where it suits and where it falls short.

However, screed is less well known in general circles. Knowing how effective it can be, especially when it comes to underfloor heating, we decided to talk you through with a guide on what screed is and why it’s perfect for this job specifically.

What is Screed?

Screed is a type of mortar that lends itself to surface level installations, due to its ability to produce a smooth, flat surface – perfect for then installing flooring such as carpet, laminate or hardwood.

It’s usually made with very fine grade sand, giving it a malleable, liquid-like property that makes it easy to pour into ‘molds’ – while it also dries relatively quickly, making it suitable for projects that need to maintain a speedy pace towards completion.

It typically sits above a hard concrete base, which lies at the bottom of the installation providing a solid surface to pour the screed into. There are many types of screed, but most installations are completed with one of two types: semi-dry screed or liquid screed, with each having differing advantages and disadvantages.

Semi Dry

Semi-dry screed is the traditional form – using a mix of sand and cement at varying ratios depending on the job at hand, usually at 3:1 or 4:1. Water is then added, bringing the screed to life and creating a smooth consistency.

It’s best applied with expert hands – as this form is less malleable, meaning it needs an experienced installer to help level off and provide the professional finish that you are looking for. Trowels and other flat-edged tools are perfect here, while you can also add Polypropylene fibres to increase the strength of the mixture.

Liquid

Often referred to as self-levelling screed or flowing screed, this form of the material has far less viscosity and exhibits liquid qualities far more closely. This is great as it does not require the use of professional hands or tools to level it off – due to the liquid qualities the material simply levels off itself.

Liquid screed often takes less preparation too, as you are able to pour it directly on to the surface you’re working with without having to mix with water – while it then dries much quicker, allowing you to press on with the project.

What Makes Screed Good for Underfloor Heating?

While the use of a particular type of screed will depend on the unique requirements of your project, it is undoubtedly the best for this type of installation due to the universal qualities of all types of screed.

The nature of the material means once the underfloor heating systems are in place, you can pour the screed directly over the top of it – filling up the mold, encasing the pipework and levelling out to a perfectly smooth floor on the surface.

The fact that there are no air pockets in this method means that heat from the underfloor piping reaches the room as efficiently as possible.

However, there are mistakes to be made here that you should be sure to avoid. Part of commissioning the underfloor heating system is turning it on for the first time, allowing the heat from the system to speed up the drying of the screed around it – but if this is done too early, you could end up with cracks in the material, leaving you with extra tasks to complete.

The material has increased malleability, but as a result, is significantly less strong than traditional concrete.

What is Quikrete and how do you use it?
29th September 2021

Quikrete is an all-purpose, do-it-yourself fast setting concrete, perfect for consumers trying to save money, time and energy on concrete work or repairs.

Selling itself as ‘easy to make and apply with just one set of hands’, this concrete mix attempts to take the power away from contractors and heavy machinery, and put it in the hands of the homeowner.

For example, the passing of the seasons often leaves its marks on concrete structures, with fluctuating temperatures causing expansion, retraction and as a result, cracking.

Quikrete allows just one person with a paintbrush to remedy the issue, with little to no hassle. You can even give other worn out areas a brush up, replenishing that newly laid look.

How do you use Quikrete?

Using Quikrete is much easier for the individual than working with traditional concrete. While most concrete is incredibly tough to mix, especially without the expertise or machinery, Quikrete have a simple to follow formula that will have your projects roaring along in no time.

As a general rule, mix one part water with five parts mix, and you’ll have perfect Quikrete – it may take some experimentation, but once it has a consistency like that of modelling clay, you’ll know it’s ready to go.

Quikrete vs Ready Mix Concrete

Ready mix is the go-to for many people working on concrete projects. Mixed by professionals and delivered to site, it takes away both the need to hand mix and the pressure of getting your mix absolutely spot on.

As well as being vastly experienced in the trade, professionals have access to industry machinery that will always produce a higher standard of concrete than achievable at home.

Professional services can listen to your needs and specifications, and hours later have the exact concrete mix you needed for your project. So why use an alternative like Quikrete?

When buying ready mix, you get what you pay for – professional concrete for professional prices, with all the equipment that comes with it.

When it comes to smaller projects, Quikrete will do a proficient job – without the need to spend big, or stress over getting heavy machinery onto your property. In addition, Quikrete makes touching up cracks or worn out spots incredibly easy.

However, for larger projects and that professional finish – there is no substitute for industry experience.

Why Build a Concrete House?
17th June 2021

Concrete – it’s a grey, dull substance. But it can make beautiful homes. Chosen for its durability, versatility, and easy transport to site, concrete is a popular choice for people looking to build or extend their home. 

But this time, we’re not talking about the concrete blocks that are commonly used to construct properties and housing estates. 

Poured and precast concrete is one of the most popular new ways to build a house, with more people saying goodbye to concrete blocks, and opting for the angled lines and soft curves of concrete-filled custom-made moulds. 

Additives are usually added to the standard concrete mix to give it more favourable properties. Thanks to the reinforced mix, concrete houses are more energy efficient, more insect and mould resistant, and more disaster resistant than houses made from standard building materials. 

The fact that concrete houses are more expensive doesn’t put people off. That’s because properties made from concrete are more cost-effective in the long run – think lower energy bills, and less maintenance and upkeep. 

Combined with industrial-esque glass and steel, concrete is the perfect choice for people that not only want to make a statement, but for people who want to be more environmentally friendly when it comes to heating, and constructing their home. 

Wright Minimix provides concrete pumping services

It goes without saying that if you’re going to build a property made entirely from concrete, you’ll need a concrete pump. At Wright Minimix, we have six concrete pumps available, meaning we can service all scales of concrete pumping. 

If you’re looking to contract a concrete pumping company, get in touch with Wright Minimix team. They’ll be able to advise you on the concrete mix and pump required to complete the project and provide a fast and reliable concrete pumping service. Give the team a call on 0117 958 2090.

Bricks vs solid concrete blocks: which is better?
31st March 2021

There are several main differences between clay bricks and concrete blocks, in terms of composition and usage. As a building material, they should be carefully selected according to the type of project and the intended use of the building. We break down the benefits of each.

The differences between bricks and solid concrete blocks

Bricks and concrete blocks are made from different raw materials, meaning they have different structural compositions. Brick is made up of sand, lime and concrete materials, while concrete blocks are produced from aggregate consisting of crushed sand or stone. 

Concrete blocks have a much higher water resistance than bricks, and their compressive strength is higher. Concrete has a shorter life than brick, though it still gives efficient results for up to 100 years. It is also incredible durable and can be painted more easily than brick, which secretes metallic salts that can cause paint to peel off. 

One of the main advantages of solid concrete blocks is that they offer outstanding fire resistance and the very highest fire safety rating. They're often favoured for their thermal efficiency and sound insulation. 

Which is better?

There is no simple answer to this, as it depends on the nature of your project and the intended use of the building. If sound insulation, fire resistance and thermal efficiency are priorities, then solid concrete blocks could be the right choice for your construction project. It's also worth noting that concrete blocks can be painted easier than brick can, giving you more flexibility in terms of design options and finishes. 

About our solid concrete blocks

We supply high-strength 100mm 7.3N solid concrete blocks for use in cavity and solid walls, load-bearing and solid partitions, columns and block and beam flooring. 

Our concrete blocks have a tolerance of D1, a mean compressive strength of 3.6 - 30N/mm2 (unit strength) and a shear bond strength of 0.15N/mm2 (tabulated value). Available in packs of 88, they are available for delivery or collection from our concrete plant in Avonmouth, where they are manufactured.
