CRM has extensive experience in inspecting and reporting on roof drainage problems, and designing cost effective solutions. Providing a UK wide service, CRM are completely independent, and will suggest the best solution for every building, taking into account access, building use and clients requirements.

Our experience over the last 9 years has covered some of the UK's largest retail and distribution organisations, as well as schools, hospitals and leisure facilities. With particular expertise in the physical hydraulics of both gravity and siphonic drainage, CRM can bring an expertise to bear well outside a knowledge of British Standard requirements. If required, physical mock-ups of systems or parts of systems can be constructed and checked to ascertain performance.

We also provide an expert witness service for failures in gravity, siphonic and underground drainage systems.
