Culverts and gutters can be subjected to hydrostatic pressure due to the presence of ground water produced by rainfall or a rising water table.

Drainage must be incorporated beneath the concrete apron or behind the trench and gutter walls during construction so that the groundwater can be intercepted and directed towards an outlet. Beyond the technical performance delivered by our geocomposite drainage solutions, they also make installation faster and easier to accomplish than conventional solutions using granular solutions.
