Technical Information

Floorcrete floor screeds are pump applied, self-levelling, synthetic anhydrite. Ideal for sub floor levelling, they provide a smooth, flat surface for the application of all floor finishes.

Suitable for most commercial and domestic buildings as a levelling layer, Floorcrete screeds offer complete versatility of use: with thermal and acoustic insulation, electrical services and under-floor heating systems.

Using Anhydrite rather than Cement in the screed means:

  • Minimal cracking and no curling
  • Rapid strength development
  • Foot traffic in 24 to 48 hours
  • Self-compacting
  • Protein free
  • Environmentally friendly product

Strength and versatility mean:

  • No construction joins
  • No reinforment
  • BRE Test Category A BS8204
  • Weight saving due to low design thickness
  • Speed of application
  • Reduced build programmes
