Floor screed is a cement-based mixture installed over a subfloor to create a smooth and level surface. It is typically made from sharp sand and cement, although fibres or additives may be included to increase strength. The screed forms the base for final floor coverings such as tiles, carpet, wood, or vinyl. In some contemporary interiors, screed can also be polished and used as the finished floor. Its main purpose is to eliminate uneven areas in the slab beneath.
What floor screed is used for
Levelling uneven floors
Screed fills dips and irregularities, creating a flat surface for flooring installation.
Providing a strong base
It supports the final floor finish and helps prevent cracking or movement.
Encasing underfloor heating
Screed surrounds heating pipes and distributes warmth across the floor surface.
Improving insulation and sound control
Floating screeds can be installed over insulation layers to improve thermal performance and reduce noise.
Heavy-duty and decorative uses
Certain screeds are reinforced for industrial environments, while polished screed can provide a modern design finish.
Common screed types
Traditional sand and cement screed, flowing liquid screed, and thin self-levelling compounds are commonly used depending on the project.
Why it matters
Correct screeding protects the finished floor and supports compliance with standards such as BS 8204. Floor Screeding Essex delivers professional screeding services across Essex.
