For Abengoa Bio-energy's new production site, Genap supplied wastewater storage reservoirs lined with MPG 950-20 membrane for chemical resistance. The concrete retaining wall structures were finished with a protective fabric and MPG membrane, followed by leak tightness testing using geoelectric methods.

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.
