List of references
Recommendations for the design and installation of flooring bonded to a concrete screed or base, that provides a tough, durable wearing surface with enhanced resistance to abrasion and dusting. Recommends thicknesses and mixes for 3 classes of flooring, work on site, inspection and testing including slip resistance.
