Cemfloor

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.

A Liquid Screed Solution

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.

Domestic

  • Cemfloor provides the ideal solution for the domestic floor market. Its flowing properties make it easy and fast to install, and yet it is based on Cement and therefore has none of the concerns inherent with other flowing screeds. There are no special measures required before applying adhesives or floor finishes to it and, as an added bonus, it dries relatively quickly when compared to other flowing or "ordinary" screed materials.
  • Cemfloor has only been in Ireland & mainland Europe for a few years and was introduced to the UK this year but is already attracting huge attention and demand for its extremely high quality. Since it seems to "tick all the boxes" it is easy to see why!

Commercial

  • The commercial flooring market requires hardwearing and durable floors due to high traffic volumes, easy and fast to install, strength and cost effective. Cemfloor ticks all the boxes and it has been developed for optimum speed and suitable for bonded, unbonded and floating screeds. Cemfloor Screed is an ideal solution for commercial projects and is produced in accordance with BS EN 13813:2002 screed material and floor screeds. The installation time of Cemfloor screed is much less than that of traditional sand and cement screeds; therefore, the building time of the project is greatly reduced. Cemfloor can also be foot trafficked after 24 hours allowing other trades to continue working on the project after the screed has been installed.  Due to Cemfloors self-levelling properties smooth, level floors are easily achieved which simplifies the installation of the final floor coverings. Since Cemfloor is a cement based screed; there is less risk of chemical reactions taking place with other products such as tile adhesives and other cement because based final floor surfaces.
  • Cemfloor is also ideally suited for use with underfloor heating due to its high thermal conductivity and reduced screed depths; this leads to a much more energy efficient and responsive heating system. Cemfloor is produced in ISO 9001, BSI & Kitemark certified batching plants and is delivered to site ready for use; this ensures that the product is consistent from batch to batch and eliminates any errors that can occur when products are mixed on-site in uncontrolled conditions.
  • Cemfloor can be tailored to various industries such as manufacturing, medical, hospitality, retail, warehousing etc.

Underfloor Heating

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.
