About this Product
Features and Benefits of Liquid Floor Screed.
Liquid screed, also known as flowing screed, calcium sulphate screed or anhydrite screed, is the modern alternative to conventional Sand and Cement screed. It is designed to provide a smooth level surface in both commercial and domestic buildings prior to application of floor finishes and is fast becoming the popular choice for use with underfloor heating systems.
Due to its greater strength it can be laid at a lesser thickness than Sand & Cement, which means less cover over pipe work, thus making your underfloor heating far more efficient and with twice the thermal conductivity of a sand & cement screed, it gives your heating a faster reaction time, saving you up to 10% on running costs.
Hills concrete have heavily Invested In a new fully computerised liquid screed batching plant capable of producing and delivering all of your floor screed requirements. We specially mix our liquid floor screed to suit your application and deliver it at a time convenient to you; all for a competitive price. Expect a friendly service from a member of our professional team, tailored to your individual project.
Key Benefits from using Liquid screed.
- Encapsulates heating pipes without leaving any voids. The heat transfers through the screed, maximising thermal conductivity of the floor, making it an efficient and cost saving screed system.
- Has a thermal conductivity of 2.0w/mK +/- 0.2.
- Can carry pedestrian traffic within 24-48 hours
- Anhydrite liquid screed is free from protein and doesn’t harbour potentially harmful bacteria, so it’s ideal for health care projects.
- Liquid anhydrite screed can be laid thinner than conventional sand cement screeds.
- Liquid Screed can be force dried through the underfloor heating commissioning process as early as 7 days after installation.
- Less prone to shrinkage than sand cement screeds, requiring fewer construction joints. Construction joints can be set every 30-40 linear meters
- Productivity can be up to 2000m2 per day
- Eco friendly binder is made from 98% recycled material.
- Anhydrite liquid Screed is non-combustible, avoids the need for reinforcement
Suitable Applications- For use with under floor heating
- Unbonded, bonded or floating floor construction
- Ideal for both new build and renovation work
