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.

We would like to take this opportunity to share a statement from our Directors in regard to the current situation and our response:

"At this time we are Covid free and taking on orders as usual.

This is a developing situation beyond our control and we have no idea how badly our ability to supply will be affected. We do not intend to voluntarily close our business but all our personnel are expected to follow the government guidance should they exhibit symptoms. What effect this ultimately has on our workforce and numbers at work we do not know and cannot guess. At worst we expect to be able to carry on with a limited supply to those customers who are able to work themselves. Please keep calling us to place orders."

The entire team at Wright Minimix thanks you for your continued support at this time.

25th February 2020

The success to any project is managing your time effectively so to ensure your delivery of ready mix concrete is smooth and stress free, follow these tips from the experts at Wright Minimix, a leading manufacturer and supplier of concrete.

Choose the right ready mix concrete contractors 

Possibly the most important factor of a successful concrete delivery is choosing the right contractor in the first place. A concrete contractor that has several years of experience working in the industry, has built up a respectable portfolio and can provide testimonials from happy customers are all good indicators that your chosen supplier can deliver exactly what they promise. 

Establish what you need the concrete for

Calculate how much concrete you will need 

Once you’ve settled on a concrete contractor and established what type of concrete you require, your next step is to calculate how much you need. It’s incredibly important to get this right as you don’t want to be left with too little and having to order more or left with too much and then having to organise and pay for its disposal. If you’re not sure how much concrete you will need for your project, use our handy online volume calculator to give you a good estimation.

Prepare the site for your delivery 

Last but not least on the road to a successful concrete delivery is making sure your site it prepared to receive it.
