Trenchless System
Typically required to install sewer pipes in poor ground conditions or under rivers, railways and existing infrastructure such as roads and buildings, trenchless installations use a wide range of techniques to excavate holes into which pipes are pushed.
Denlok pipes can be easily pushed through the ground thanks to the use of an integrated coupling that is in line with the external pipe diameter. Manufactured to BS EN295-7 standards, Denlok pipe products are available in one and two metre lengths, and a wide range of diameters.
