Anhydrite Screed

The Product:

Anhydrite screed is a flowing screed based on a mixture of sand aggregate and a calcium sulphate binder.

Our Anhydrite screeds are delivered to site premixed by nominated concrete suppliers under BS EN 13454 stringently controlled conditions ready to use.

Anhydrite screeds are eco friendly based on 50mm every 1000m2 you will save 38 tonnes of landfill.

Anhydrite screeds have higher thermal conductivity allowing you to reduce heat input into the screed vs. heat output.

The Anhydrite Screed is placed using the normal process of setting levels to achieve the required depth.

The natural flexural strength of this product and the lack of voids mean it may be laid substantially thinner than conventional materials. Over insulation minimum thickness is normally 40mm for commercial application and 35mm for domestic application. When used in conjunction with underfloor heating pipes Anhydrite screeds can be laid to a minimum thickness of 45mm.   

This product is available for supply throughout Galway, Limerick, Tipperary, Westmeath, Cavan, Sligo, Roscommon, Leitrim, Offaly and Clare.
