This schedule specifies the requirements for the A0500G and A1800H Alphaliner full length UV cure liner systems as manufactured by RelineEurope GmbH for the rehabilitation of gravity sewers and drains. This schedule includes two resins: Alphaliner (UP resin) and AlphalinerVE (Vinylester resin).
The approval is not applicable to Leaktightness of end seals or reconnection of laterals.
The systems comprise of a glass fibre reinforced woven sleeve which is factory impregnated with an ultraviolet (UV) light curing resin. There are two variations: A0500G and A1800H which have different percentages and orientation of glass within the sleeve matting. The resin options include Alphaliner (UP resin) and AlphalinerVE (Vinylester resin). When installed and cured in-situ, the product forms a structural liner within the host pipe.
The A0500G and A1800H Alphaliner and AlphalinerVE systems are used for the full-length rehabilitation of gravity sewers and drains. Liners are for circular pipes with internal diameters between 150mm and 2,000mm and egg-shaped pipes between 200mm x 300mm (DN250mm equivalent) and 1,400mm x 2,100mm (DN1,750mm equivalent).
