Liquid Screed

Liquid screeds are Anhydrite self compacting flowing screed that conforms to BS EN 13813:2002, the British standard for floor screeds. Liquid floor screed or flowing screed has been used in Europe for the last twenty years, they are now gaining huge popularity in the UK for their ease of use, flexibility, environmental impact and labour saving qualities.

A liquid floor screed is a fast, efficient way to install a new floor in all kinds of commercial screeding and domestic screeding projects, small or large. 2000m2 of liquid floor screed can easily be laid in just one day. It simply wouldn’t be possible to lay the equivalent area using a traditional sand and cement floor.

Liquid floor screed is the number one choice when installing under floor heating. It is self compacting so voids are eliminated which allows heat to be transferred evenly across the floor. Significant savings on energy costs can be achieved due to the efficiency of the system. Liquid screed has twice the thermal conductivity of a traditional screed.

Liquid flowing screed can be used in new builds and renovation projects. It is suitable for domestic and commercial buildings and has been used in hospitals, schools, colleges, department stores, hotels and airports.

Thermoscreed undertake liquid floor screeding in Hampshire, Dorset, Surrey, West Sussex and Berkshire

Quality Control

Liquid floor screed is pre mixed at the batching plant and the viscosity checked prior to leaving for delivery. Once on site, we then check the viscosity again to ensure it has maintained its quality whilst in transit.

It is difficult to put these quality control measures in place with traditional screed. There can be wide variations during travel and site installation. Gyvlon floor screed has extremely low shrinkage which reduces the risk of cracking and will not curl.

Liquid Screed Depth

Flowing Floor Screed can be laid at lower depths than traditional screed, 25mm bonded, 40mm on to insulation and 50mm on to under floor heating. The reduction in depth can result in liquid screed being a more competitive option than sand and cement. The reduction in depth also means that the screed is ready to receive floor finishes quicker than a traditional screed. Lower depths in screed will also make an under floor heating system more responsive during heat up and cool down.

Minimum Depths

Fully Bonded 25mm
In contact with the substrate / Unbonded 30mm
Floating commercial 40mm
Floating domestic 35mm
Cover to conduits / under floor heating pipes 25mm
(Pipes are usually 16mm to total depth 41mm)

Strength

Liquid flowing screed can achieve a standard strength of C30N/mm2.
Floors do not require any reinforcement or fibres to add to their strength.
