Excavation pit for industrial area Haven VII A+B

Along the A59 near Waalwijk, Genap developed a membrane construction for BAM NBM Infra & Martens van Oord for a new industrial area. 300,000 square meters of 0.8 mm PVC membrane were installed to create a watertight excavation pit and protect the nearby nature reserve from drying out.

Waterproof membrane structure for sewage system

Genap constructed a water-retaining membrane system for the installation of a sewage system below the groundwater level. The membrane system was submerged based on its own weight, without the use of a pontoon, to save costs and maximize efficiency.

Membrane constructions under tunnel approaches

For the reconstruction of the Peelo Zuid road section, an underpass intersection and bicycle tunnel are planned, with membrane layers for construction pits following the U-polder principle. Genap supplied 8,000 m² of PVC membrane and 4,000 m² of protective fleece for this project for BAM Wegen bv, where spatial constraints necessitated an innovative approach.

Underpass 'Koailoane'

Centrale As Noord membrane construction underpass

The underpass of Koailoane, part of "De Centrale As" between Dokkum and Drachten, combines an elevated cycle path with a wildlife passage. Genap installed a liquid-proof membrane to keep the groundwater out, covered with ballast. For this innovative project, 150,000 m² of membrane was used to complete it.
