Harmer Building Drainage has been awarded BBA Agrément certification on its SML cast iron drainage for below ground applications, adding to its already certified above ground range. The certification covers the installation of foul and surface water pipes, couplings and fittings in domestic, commercial and public buildings.

Harmer’s below ground drainage was assessed for installed strength, water tightness, flow characteristics, resistance to chemicals found in domestic waste water, resistance to elevated temperatures, and durability. The certification gives architects, specifiers and contractors the assurance that Harmer’s materials and manufacturing have undergone rigorous testing and inspection in order to achieve compliance.

Wayne Wilmot, National Sales Manager for Harmer Drainage comments: “Achieving BBA certification confirms our SML below ground range is fully compliant to a leading industry standard. Our SML range is a lightweight, dry jointed pipework drainage system at the leading edge of cast iron technology. It delivers exceptional performance and strength, and is 100% recyclable. Contractors and specifiers who choose our products know they will stand the test of time and function at the highest standard when used in performance-critical projects.”

Harmer’s above and below ground drainage has been specified and installed in a wide range of projects, including the Hilton Hotel near Minories, London; the Royal Holloway University of London; and Redrow Homes in Tavistock Gardens.
