At the Ewijk junction, Genap provided the membrane sealing of incineration bottom ash elevations, using 2mm HDPE membrane and drainage mats for stability. This included waterproof penetrations, totaling 75,000 square meters of materials.

Genap installed 22,000 square meters of SureGrip concrete protection at the new purification plant in Amsterdam West. Betonson produced tank elements, onto which our custom-made protection plates were mounted. Subsequently, our 22 technicians welded these on-site to ensure they were leak-proof.

At the sunken eastern ring road N242 in Alkmaar, Genap installed 35,500 square meters of PVC membrane for a viaduct construction. A geotextile was used due to the shell-rich soil. Using a self-developed winch system, the membrane was pulled over water and sunk by its own weight. The leak tightness was subsequently tested by TNO.

Genap installed HDPE membrane structures at the Beatrixhaven connection road on behalf of Grondbank Nederland BV to seal incineration bottom ash fillings, thereby protecting the environment. The project included 18,500 square meters of NW20 protection fleece, 18,500 square meters of 2 mm rough HDPE MST/MSB membrane, and
14,000 square meters of drainage mat.
