Cemfloor Flowing Screed
Flowing screed is a pumpable, self-compacting screed that flows into place and levels itself. It lets us cover large areas quickly, with a very flat finish and less labour than a conventional screed.
Wet flowing screeds are one of our specialisms, alongside traditional screeding.
Benefits of flowing screed
- Speed: large areas can be laid in a single visit
- Flat, level finish: consistent results across big floor areas
- Ideal for underfloor heating: flows around pipework and gives good contact for efficient heat transfer
- Less disruption: pumped into place with fewer people on site
- Strong and durable: suitable for commercial, industrial and residential use
Where we use it
- New-build housing and apartment developments
- Offices, schools and public buildings
- Large commercial and industrial floors
- Any project with underfloor heating
How it works
We'll assess the substrate, build-up and access during the site survey, then plan the pour. Flowing screed needs proper curing and drying before floor coverings, and we'll talk you through the process so there are no surprises.
Frequently asked questions
What is flowing screed?
Flowing screed is a pumpable, self-compacting screed that flows into place and levels itself. It gives a very flat finish and lets us cover large areas quickly.
Is flowing screed good for underfloor heating?
Yes. It flows around the heating pipes, so they are fully surrounded, and it is widely used with underfloor heating. The heating must be commissioned gradually, following the guidance for the particular screed and heating system, and we'll talk you through the process.
How soon can I walk on it, and when can I lay floor coverings?
It can usually be walked on after a short time, but it needs to dry before floor coverings go down. Timings depend on the thickness and conditions on site, and the moisture level should be tested first. We'll give you guidance when we survey the site.
Does the screed need to be pumped?
Yes. Flowing screed is pumped from a delivery vehicle through hoses, so we check access and the distance to the working area at the survey.
Is it more expensive than sand and cement screed?
It depends on the area, the depth and access. Flowing screed is quicker to lay over large areas, which can offset the material cost. A free site survey gives you a clear quote so you can compare. For smaller areas, traditional sand and cement screed may suit better.
