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
Gebr. Van der Lee Contracting Company | Scharsterbrug-Joure, the Netherlands
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.
Dura Vermeer Divisie Infra BV | Houten, The Netherlands
Construction pit for tunnels around N421 bypass
The N421, constructed in 2015 between the A12 and Houten, includes tunnels under roads, for which Genap installed waterproof membranes. Structure 1 received 4,500 m² of PVC membrane, and Structure 3 received a combination of geotextile and PVC to ensure anhydrous construction pits.
