1.1  Scope
This document sets out procedures for the preparation, laying and fixing of resilient sheet and tile floor coverings in all forms including flexible PVC, semi-rigid PVC, hybrid modular, linoleum, and rubber. It also applies to self-adhesive tiles. This document gives details of the work necessary to prepare subfloor surfaces, together with procedures to be adopted for laying the resilient covering. This document does not apply to the laying of textile floor coverings (carpets), bamboo, laminate, engineered flooring, melamine, timber or cork products.
