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.

Ready Mix Concrete Prices Guide
10th January 2019

Our ready mix concrete prices are cost-effective, especially for large-scale projects. However, there are a few things you can do to avoid spending more than you need to.

Measure for ready mix concrete correctly

We supply the exact amount of concrete you specify, and our ready mix concrete prices work on a volume-based system. If you measure your site correctly, this ensures that you only ever pay for the amount you need and use, but if you under or overestimate the volume of concrete required for your project, this can prove costly.

If you end up ordering too much concrete and need to send some back, you will need to pay disposal costs unless the batch is fit to be remixed and resold in accordance with our returns policy. Alternatively, ordering too little concrete can prove equally costly in terms of potential delays to your project and can compromise its effectiveness.

You can use our online concrete volume calculator tool to work out how much ready mix concrete you will require for your project, to ensure you only pay the best price for your ready mix concrete. If you have any further enquiries about estimating the volume of concrete needed for your project, call our expert team today on 0117 958 2090.

Prepare for your concrete delivery in advance

Our concrete mixer trucks can deliver ready mixed concrete up to 2.4m from the rear of the vehicle and are allotted a delivery time of 30 minutes. If a delivery truck is required on your site for longer than this period, then this can affect your ready mix concrete price.

There is no point in our concrete delivery truck turning up with your batch if you haven’t thought of a way to get it to your site, as this will mean a lot of wasted time and potentially lead to additional costs for concrete disposal.

You should therefore consider if your site has any obstruction issues and are prepared to receive your concrete delivery. If your site is impossible to access for a mixer, then why not consider one of our concrete pumps for hire? We have a range of boomless and boom pumps available that make easy work of even the most difficult to access sites.

When should screeds be used over concrete?
14th December 2018

Our concrete experts share their top tips on why liquid screeds can be preferred to ready mix concrete

Liquid screeds have huge benefits in all kinds of construction projects. Whilst concrete is a big favourite for large-scale, often outdoor projects, the flowability and smoothness of screeds presents a good option for smaller indoor projects. Check out our top reasons for choosing screeds in your project.

Underfloor heating

Perhaps the biggest advantage of screeds is that they can be used in conjunction with underfloor heating. Liquid screed will flow around your heating pipework perfectly, meaning that there are no air gaps for heat to escape into. Heat can rise from your heating through liquid screed a lot more effectively than it can through concrete, making it perfect for indoor projects.

A smoother finish

Liquid screed is completely self-evening. It doesn’t crack or curl at all, it doesn’t need sealing and it can be used on dry and wet areas. Whilst ready mix concrete is used for all kinds of construction projects, like pathways, driveways and even conservatories, screed flooring doesn’t leave lumps and bumps, making it better for projects that you’d like a smoother finish on.

Quicker job

You'll be pleased to know that screed has a quick drying time. If you’re running your project to a tight deadline, then screed will be ready between 24 and 48 hours. This means that’s there’s little disruption whilst the screed is being installed; the drying time will depend on the depth and size of the project.

What’s the difference between boom pumps and boomless pumps?
13th December 2018

When ready mix concrete or liquid screed is laid at a site, it needs a concrete pump of some kind to transfer the wet mix. The specifics of your project and the volume of concrete that you need for it will determine which of the two pumps you’ll need, but what are the key differences between the two?

Boom pumps are often used in bigger jobs. They use a remote-controlled robotic arm to deliver concrete with precision. Boom pumps don’t have to be as close to the site as they have the arm to help, and they save a lot of manual labour. They are suitable for commercial and residential jobs and are useful for accessing heights; it’s a favourite with many for their quick working time, extendable reach and cost efficiency.

Boomless pumps, as you may have guessed from the name, lack the robotic arm of the boom. Instead of transferring concrete via the boom, boomless pumps lay concrete straight from the vehicle via pipes. Our minipump however is still capable of delivering concrete over 100m vertically and 200m horizontally.

Still need to discuss which pump you’d need for your project? Contact us on 0117 958 2090 and we’ll answer any and all questions that you may have about pumping.
