Floor screed solutions with Gypsol

Product information

We manufacture Gypsol binder for anhydrite flowing screeds in quality-assured Readymix facilities throughout the UK. Gypsol screeds are also available in specific locations from volumetric on-site mixing systems.

What we do

Gypsol screed is made from our high-quality Gypsol anhydrite binder, specially selected sands, and clean water. Therefore, it offers the user a simple and effective floor-screeding solution for floating, unbonded, or fully bonded applications where a subsequent floor covering is required.
