Liquid screed – also known as flowing or self-smoothing screed – is a highly workable, pumpable floor screed that spreads evenly into place and creates an exceptionally flat, level surface with minimal finishing labour. It’s widely used in modern construction, commercial spaces, domestic renovations, and underfloor heating applications where precision and speed matter.
At Sussex Ready Mix Concrete, we supply tailored liquid screed mixes designed to meet your project requirements and deliver a smooth, durable substrate ready for floor finishes such as tiles, timber, carpet, or LVT.
Liquid screed is a cementitious floor screed with a higher fluid content than traditional screed, allowing it to flow under its own weight. This results in a smooth surface with excellent flatness and flatness tolerances – often significantly better than manually laid screeds.
It can be applied via pumping, which increases efficiency and accuracy, especially for larger floor areas or complex layouts.
Self-Levelling Surface
Liquid screed flows into place and levels itself, drastically reducing manual finishing time.
Ultra-Smooth Finish
Because it settles uniformly, liquid screed produces an exceptional smooth and level floor base – ideal for modern finish materials.
Faster Installation
Pumping technology and fluid consistency make installation quicker than traditional screed in large or open areas.
Great for Underfloor Heating
Liquid screed is ideal for encapsulating heating pipes and creating an even surface that maximises heat transfer.
Reduces Labour & Waste
Less trowelling, less manual levelling, and accurate volume delivery reduce on-site labour and material waste.
Liquid screed is suitable for wide-ranging applications, including:
Residential floor installations (homes, extensions)
Commercial and retail spaces
Office fit-outs
Warehouses and industrial flooring
Underfloor heating projects
Renovation and retrofit floors
Its fluid nature makes it especially effective for larger floorplates and intricate areas where flatness tolerances are tightened.
Liquid screed is typically pumped to the placement area and flows into position under its own weight. Best practice application includes:
Ensuring a clean, stable base or insulation board
Securing edge restraints where required
Pump placement coordinated with site access
Controlled placement to maintain level tolerances
Curing and drying according to screed type
Our delivery team can coordinate with your installer to support placement timing and site requirements.
Standard Liquid Screed
Suited for general floor preparation and typical building projects.
Fast-Drying Liquid Screed
Developed to reach dryness sooner, allowing earlier floor covering installation — ideal where programme pressure exists.
Underfloor Heating Liquid Screed
Engineered to encapsulate UFH loops efficiently and provide superior heat transfer performance.
If you need a specific specification for strength, drying time, or thermal performance, our team can help define the right mix for your project.
We supply liquid screed throughout: Haywards Heath, Brighton, Worthing, East Grinstead, Lancing, Uckfield, Burgess Hill, and surrounding areas.
Our team works with your schedule, site access needs, and installer programme to ensure the screed arrives at the right time and specification for a smooth placement.
