What Is Liquid Screed?
Liquid screed (also known as flowing screed or self-levelling screed) is a pumpable, fluid floor screed that flows into place across your sub-floor, self-compacting and self-levelling to create a perfectly flat surface.
Available as calcium sulphate (anhydrite) or cementitious variants, liquid screed is particularly suited to underfloor heating systems, large open-plan areas and fast-track construction programmes — it can cover up to 2,000 m² per day.
- Up to 2,000 m² poured per day
- Walk-on in as little as 24–48 hours
- Superior thermal conductivity for UFH systems
- Reduced cracking and shrinkage vs traditional screed
- Suitable for residential, commercial and industrial projects
- BS EN 13813 compliant mix designs
Screed Types We Supply & Install
Calcium Sulphate (Anhydrite)
The most widely used liquid screed. Excellent for underfloor heating due to its high thermal conductivity. Minimal drying shrinkage, low risk of cracking, suitable for residential and commercial applications.
- Depth: 30–50 mm (bonded) / 50–80 mm (unbonded/floating)
- Compressive strength classes: C20–C25
- Walk-on: 24–48 hours
Cementitious Liquid Screed
A Portland cement-based flowing screed where calcium sulphate is unsuitable, such as areas with high moisture, external use or where bonding directly to concrete is required.
- Depth: 35–50 mm (bonded) / 50–75 mm (unbonded)
- Suitable for wet areas and external applications
- Walk-on: 24–48 hours
