Description

HDPE lining to provide an effective isolating barrier against concrete corrosion for concrete structures, sewer pipes, tunnels, manholes, chemical tanks, landfill, water reservoirs, wall in sewerage installations or civil foundations and other masonry work requiring protection from aggressive media and in corrosive conditions.HDPE lining system is a continuous, extruded and homogeneous plastic sheet membrane of flexible Polyethylene that is especially compounded to provide maximum resistance against chemical attack. The lining is extruded with T-ribs spaced *4 mm apart on one side of the sheet. The Tees anchor the lining into the concrete, thus making it integral to the structure. Whether it is a concrete pipe or wall; during construction the lining is attached to the forms and secured in place. The T-ribs are always in contact with the poured concrete which flows around them and is then vibrated to ensure a dense, void-free structure with the HDPE lining secured to its face. The HDPE linings could be produced in different forms, profiles, properties and colours to suit the intended use and the current production program covers linings of thickness 1.0 to 5.0 mm, other thickness could be supplied upon demand. HDPE linings ensure concrete protection for over **0 years, all under the quality and design requirement of ISO ***1:***0; ISO ****1:***4 and OHSAS ****1:***9.
