JLR contracts only use cemfloor liquid screed solutions, all of our operators are fully qualified in Cemfloor liquid screeding. Cemfloor and McGraths Limestone are industry leaders in the fast drying screed. We also specialise in polishing Cemfloor liquid screed along with installing underfloor heating.
Cemfloor is a high-performance cement based, free flowing, self-compacting liquid screed developed by McGraths. It can be installed quickly up to 2000m2 per day saving time, foot trafficked in 24-48 hours and dries within 10-28 days with minimal shrinkage (<0.05%). It is suitable for a variety of applications; commercial and domestic floors, underfloor heating, wet rooms, unbonded or floating floors, new builds or renovations and single or multi story projects. Cemfloor is only installed by fully approved and trained applicators ensuring quality is never compromised.
Since Cemfloor is a cement based screed; floor finishes can be applied once the screed has dried to a final moisture content of 2.5%CM. This significantly speeds up the entire build process compared with calcium sulphate screed which require a final moisture content of
0.5%. Cemfloor boasts exceptional thermal conductivity of up to 2.9W/mk and is very suitable and responsive to underfloor heating due to the fact it can be laid in very thin sections. This ensures lower energy bills and running costs. ll Floor Coverings Can Be Applied Directly On To Cemfloor, With No Need For Surface Sanding And Compatible With All Cement Based Tile Adhesives And Floor Levellers.
Underfloor heating has been growing in use over recent years and so it is becoming increasingly common for a screed to either contain or overlay an underfloor heating system. This may take the form of electric heating cables or warm water pipework. Almost invariably these screeds will be floating due to the need for there to be a layer of insulation under the heating system. In general, the screed would be installed as any other floating screed but it is likely that the inclusion of the heating system will necessitate a higher thickness. Often this will be defined as a minimum “cover” to pipework for example. Underfloor heating systems are where the benefits of flowing screeds become even greater when compared to semi dry screeds. They can be laid thinner at typically 45 to 50mm for calcium sulphate or Cemfloor instead of 75mm for traditional screed. The screed will fully encapsulate the pipe, which is difficult to achieve with hand compacted materials, and the thermal conductivity is much better.
