How to prepare your floor for liquid screed

Preparing liquid screed

 

As established concrete experts based in Bristol, Newport and Cheddar, we are ideally positioned to provide guidance on the best way to prepare for liquid screed.

Our Wrightflow Liquid screed flooring is designed to withstand even the most testing conditions and is ideal for customers looking to utilise their underfloor heating and save on their energy bills. The combination of materials, anti-crack and anti-shrink agents used in our liquid screed ensures you are left with only the highest quality concrete flooring and long-lasting results with a range of benefits.

However, this all relies on you undertaking the correct preparation work first. Find out how you can best prepare your site for liquid screed below or contact our team with any queries on 0117 9589 2090.

How to prepare your floor for liquid screed

 
  • Remove any debris from the sub floor.
  • Place insulation in 2 layers. Using dried sand to fill the void around pipes and ensure that this is level before installing the second layer of insulation board.
  • A membrane of 1000 gauge or thicker should be laid immediately under the pipework (above the insulation board) as a slip layer, and to prevent leakage of the screed before setting.
  • Install an edging strip around the edges and corners of the wall and attach securely.
  • Any shuttering across doorways or steps should be fully sealed with expanding foam or mastic to prevent leakage after laying but before setting. Pipe ducts or holes through walls also need to be sealed before placement of the liquid screed.

If you are installing liquid screed with underfloor heating

 
  • Install underfloor heating pipes and ensure that they are clipped every 400mm and more around bends. Make sure that the system is full of water prior to the liquid screed being laid. This avoids the pipework floating to the surface of the screed.
  • If you are using an ‘eggbox’ type pipe system, the membrane should be laid under the eggbox, and you should avoid using small off-cuts of eggbox to avoid any possibility of floating.
  • The minimum cover above underfloor heating pipes is 30mm therefore minimum screed thickness is normally 50mm when using a 16mm UFH pipe.

Common mistakes to avoid when preparing for liquid screed

 

Measuring the space incorrectly

Often sub-floor slope or unevenness may cause unexpected differences in the overall floor level and in the quantity of screed required. It is the customer’s responsibility to measure each room/area appropriately.

You will need to consider critical features such as door openings, minimum thicknesses/cover and required differentials in floor height between rooms. These must be agreed prior to installation and marked on the wall above the level of the finished screed so that they are present for comparison should a disagreement be raised about finished floor levels.

Any such disagreement must be brought to our attention within 48 hours of the screed being laid. Should these marks be removed or altered prior to any investigations then we will not be held accountable for any level issues.

Ordering less screed than required

Should extra liquid screed be required over that originally ordered and a separate delivery needed, the client will be charged extra costs,  so it is essential that a proper estimate is made by the client to avoid this.

The Dangers of DIY Concrete Pouring
11th June 2020

Concrete is the most widely used construction material in the world because of its strength and durability; two qualities that also means when something goes wrong in its preparation, it really shows. Pouring concrete requires knowledge, skill and careful planning as well as the right tools and materials for the job, so if you’re considering taking on the challenge yourself, make sure you check out our list of the most common things that can go wrong before you begin. 

Inadequate preparation 

Many DIY concrete pourers think preparing the ground for the concrete simply means excavating the area and clearing any plants and stones. However, this base is not enough to provide a strong concrete foundation that won’t crack, crumble or degrade as the soil settles. The ground needs to be properly levelled and compacted, and building frames. 

The wrong weather conditions 

The weather can have a major impact on the quality of the concrete mix, the pour itself, and can continue to damage the concrete in the hours and days after. When mixing concrete yourself, you’ll also need to consider the area’s general climate as this can affect the long term durability of your concrete and so you will need to make adjustments to your mix. 

Getting the water to cement ratio wrong 

Adding too much water to cement is one of the most common mistakes made by DIY concrete pourers, possibly because the runnier the mixture the easier it is to work with. However, if the concrete mixture is too runny, or indeed too think, it will have problems in its appearance and durability once its set. 

Missing equipment and tools

Dealing with concrete is time sensitive as it will soon start to set once it has been poured so it’s imperative to have all the right tools and equipment you need to hand. If you don’t, then you run the risk of the concrete setting without your control and a potentially lengthy and costly removal process. 

Not taking safety seriously

Perhaps the most significant mistake DIY concrete pourers can make is not taking the health and safety of themselves and others seriously enough. Though concrete is a safe material to work with, it doesn’t come without any hazards and you will need to take appropriate precautions to protect your eyes, ears, and respiratory system and take care when handling heavy objects. 

When to call in the ready mix concrete professionals 

The best way to ensure your concrete pour is successful, and that your concrete is the right mix to last for years and years, is to call in the professionals.  At Wright Minimix, we help ensure your project is a success by supplying the perfect mix of concrete right where you need it. What’s more, when you use our ready mix concrete, you only order what you need, saving you time, money and the risk of having too much concrete that you’ll then have to waste resources on disposing.

How To Successfully Install A Concrete Shed Base
01st June 2020

Whether it’s for storing tools and gardening equipment or to turn into something a little more fun, a shed is a fantastic addition to any garden. So, if you’re looking to add a shed to your outside space, you’ll need to make sure it has a solid foundation to ensure its longevity and durability which is why we’ve put together this quick guide to installing the perfect concrete shed base.

1) Where will your shed go?

The first thing you’ll need to decide for a successful concrete shed base is where you want the structure to go in your garden. If it’s placed too near a wall it will be difficult to apply your wood treatment and finish and it might restrict your access. Don’t forget if it’s too close to a tree or large plant, the roots may affect the stability of the shed base.

2) Preparing the sub base

Once you’ve decided on your perfect location, it’s time to prepare the ground by:

  • Digging the top layer of soil down to at least a 3 inch depth
  • Constructing a wooden framework that runs the perimeter of the shed base and sit approximately 3 inches above garden level
  • Laying around 3 inches of compacted hardcore (brick rubble is also suitable) and if appropriate, compacted sand.

3) Pouring the concrete

Now you have prepared the ground, all you have to do is sit back and relax as the experts at Wright Minimix prepare the perfect concrete mix for you and deliver it straight to your home. By choosing ready mix concrete, you ensure the concrete you use for your shed base is correct, you order the exact amount you need to reduce waste and ensure you only pay for what you need.

What is reinforced concrete?
19th May 2020

Reinforced concrete is concrete that has steel bars embedded within it. The two materials then act harmoniously to absorb the tensile, compressive and shear forces acting upon it.

Why is concrete reinforcement necessary?

Solid concrete has incredibly high compressive strength. This means that it can cope with large amounts of pressure applied to its surface without breaking. In comparison, concrete’s tensile strength is usually less than 10% of its compressive strength, which makes it vulnerable to forces that could pull it apart, like earthquakes, vibrations and high winds. Steel rebar absorbs tensile stress applied to the concrete and significantly increases its ability to withstand it.

How does concrete reinforcement work? 

When embedded within concrete, steel bars, rods or mesh form a strong bond with the mix as it cures to create what is essentially a single structure. The steel is arranged in such a way to ensure maximum effectiveness in overcoming tensile forces, whilst the concrete makes up for the compressive strength that the steel bar lacks.

Do I need reinforced concrete for my project?

One question that we get asked frequently is if they will require a reinforced concrete slab for their project. Generally, reinforced concrete is recommended for all commercial applications. For DIY projects, it depends on both how large the concrete slab will be and its intended use. If you want to erect a small wooden shed, it shouldn’t be necessary, though you may want to consider steel reinforcement for a large driveway to avoid cracking.


We are proud to be your one stop shop for all things concrete in Bristol, South Wales and the surrounding areas. Whether you are working on a commercial contract or a job in the garden, we can deliver quality concrete mixes straight to you on site. We can even arrange steel reinforcement on your behalf as well.
