Liner fragments: Samples taken for three-point bending tests

This IKT Comparative Test assesses the suitability and the practical usability of CIPP liners available on the market for sewer laterals. The central focus is on highly practically orientated comparison of the products, in order to be able to provide waste-water system operators with impartial and technically substantiated information on the strengths, weaknesses and potentials/limitations for use of the products tested. The test programme itself has been developed jointly with the participating system operators.
