Liquid Floor Screeding
Throughout the Six Counties we can pump and arrange supply of liquid screed flooring which is fast becoming one of the most widely used techniques in both new builds, and in restoration building products. From self-build homes in Gloucestershire, office refurbs in Cheltenham to new commercial developments in and around Tewkesbury Six Counties Screed Services use only the highest quality products available on the market to deliver you a first-class end product for your property, from manufacturers who have tried and tested their products in domestic and commercial environments nationwide.
Installations Across Six Counties
Six Counties Concrete carry out screeding installations in Herefordshire, Worcestershire, Gloucestershire, Warwickshire, Oxfordshire and Wiltshire for large & small construction companies, Underfloor heating installers and self builders & shopfitters. All our installations are carried out to BS8204.
- A perfectly flat finish
- Does not require curing
- No need for reinforcement
- Extremely low shrinkage, minimises the risk of cracking
- Does not curl
- Protein free - cannot harbour harmful bacteria
- Significantly reduced thickness compared to sand-cement screed
- Weight saving as a result of thinner section
- Dries at a rate of 1mm per day up to a screed depth of 40mm, for depth over 40mm allow 2 days per mm
- Can be force dried as early as 7 days
- Can be walked on in 48 hours
- Suitable for floating floor construction
- Ideal for use with UFH systems
- Rapid commissioning of the UFH
- Large bay sizes of up to 30-40 linear meters
- Up to 2000m2 a day can be easily achieved
Please note that it is important that the preparation of the floor prior to installing under floor heating and floor screed is carried out to the highest standard.
Water Tight
The building must be made be weather tight - the roof and external doors /window openings must be fitted with either final fixtures or clear polythene.
Exposed Edges
Install temporary formwork to exposed edges (eg door openings or level changes)
Clean
Remove all dust, debris and contamination from the floor surface.
Insulation
Ensure that all high/low points are removed from the sub-base and that insulation boards are laid flat.
Insulation boards should be tightly butt jointed with staggered joints.
Membrane
Install a polythene separating membrane to floor (1,200 guage or similar) join with 50mm tape. Ensuring that all air pockets are removed and are free from punctures and creases.
Lap joints should be 100mm and where necessary continue the polythene up the face of all wall/floor joints to the full depth of the screed.
Perimeter isolation strip should be fixed at wall/floor junctions and around any columns, pipework etc
Under Floor Heating
When used on underfloor heating we recommend using polythene to separate the membrane.
All heating pipes and cables must be securely fixed down.
Warm water systems should be filled prior to the application of to reduce the risk of pipes floating when the screed is poured and pressure tested.
Minimum Application Thickness
- Floating commercial, 40mm
- Floating domestic , 35mm
- Underfloor heating (min cover to pipe), 30mm
Please make an allowance for tolerances and any isolated high spots as this will impact on the overall depth and material usage.
