Cemfloor

Cemfloor HPC is a specially formulated high performance concrete that can be used to create stronger and more durable floor slabs with less shrinkage and increased bay sizes to minimise joints compared to those constructed with convencional concrete. Higher comprenssive and flexural stregths are achieved enabling a reduction in slab thickness providing an improved environmental profile. High quality finishes can be achieved without power floating with the option to polish to enhance aesthetics.

 

There are 3 different products available in the Cemfloor range:

Cemfloor screeds are very responsive to underfloor heating; due to the fact that they can be laid in very thin sections and have a high thermal conductivity of up to 2.9w/mk.

Compared with other liquid screeds which generally need to be force dried with underfloor heating; Cemfloor screeds can be used in non heated floors as it doesn’t require force drying to remove moisture. Using the correct tile adhesives; tiles can be placed in as little as 5 days in nonheated floors.

ADDITIONAL INFORMATION

SUBSTRATE

Cemfloor Screed is designed for use as a bonded thick levelling screed over thermal or acoustic insulation, or as an ubonded screed on top of a plastic membrane.

FLOOR COVERING
