Woodroyd was the first company to install Calcium Sulphate based screeds when they were introduced in this country. Conventional or traditional screed materials are eclipsed by Calcium Sulphate’s significant advantages, not least of which are speed of installation, higher strength and smoother, flatter finished floors. 

Woodroyd benefits from a long tradition of installing liquid construction materials using spray and pressure pumping techniques. Having now installed many tens of thousands of square meters of flowing Calcium Sulphate screeds, the company can claim to have unsurpassed experience and the expertise to tackle any job. 

The company obtains ready-to-use screed product from Cemex, Tarmac, Lafarge (see the video below) and Bardon and installs them into most types of construction project. The greater density and self compacting qualities make Calcium Sulphate screeds ideal for use with Under Floor Heating systems where the 100% contact with the heating element provides better heat transfer.
