Installation of geomembrane constructions for infrastructure
In civil engineering, approaches to underpasses, aqueducts, and sunken roadways often incorporate geomembrane constructions as groundwater barriers. The waterproof membrane must be installed at such a level that vertical equilibrium is maintained to prevent the construction from floating.
The installation of the geomembrane at depth can be done in two ways: through the sinking of geomembrane constructions, and the application of geomembranes in dry conditions. In both methods, Genap has years of experience and has completed a significant number of impressive projects.
Geosynthetics for infrastructure products
Under water installation
By applying a synthetic layer, a waterproof barrier is created, allowing the infrastructure to be constructed in dry conditions.
Dry installation
In dry installation, a synthetic construction is applied for, among others, access ramps, underpasses of tunnels, aqueducts, and sunken roadways.
Highlighted projects Geosynthetics for infrastructure
KWS Infra | Gieten, The Netherlands
Bottom seals at N33 crossing
Genap equipped the N33/N34 intersection near Gieten, at the request of KWS Infra, with a waterproof membrane to protect the groundwater. Utilizing large pre-fabricated PVC-P sheets, installed in just a few hours using cranes, and completed with a drainage fleece and geogrid for slope stability, this project covered 60,000 square meters over 36 days.

Deepening for tunnel trough
Genap managed the sunken layout of the Hollandiastraat as part of the project at Knooppunt Joure A6/A7, where the A7 passes over the Hollandiastraat. This involved the use of a 1.5mm thick LLDPE MST MSB membrane, which is intended to keep groundwater out of the tunnel box over an area of approximately 14,000m².
