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
Cemfloor is a compatible with all types of floor coverings, cementitious adhesives, damp proof membranes and floor levellers.
APPLICATION
Cemfloor screeds should be used in accordance with BS 8204-7:2003 'Code of Practice for Pumpable Self-Smoothing Screeds'. To ensure a high quality screed it is recommended that application is carried out by a specialist screeding contractor who has completed the necessary Cemfloor training.
TECHNICAL INFORMATION
Cemfloor is produced in an ISO 9001 quality-controlled environment. Self levelling screeds produced with Cemfloor meet the requirements of EN 13813:2002 'Screed Material for Floor Screeds'.
