DIN EN 16506:2014-12

This European Standard specifies performance requirements and test methods for pipes and fittings for the renovation of underground drain and sewer systems by lining with a single rigid annulus of structural cementitious grout formed behind a plastics inner layer. This plastics layer serves as permanent formwork anchored to the grout. It is applicable to plastics inner layers and grout systems with or without steel reinforcement. This European Standard does not apply to the structural design of the lining system.
