Geoquest flood protection and alleviation solutions
Dykes or levees
Dykes or levees are active defences against floods and constitute the most common structures built to prevent flooding and submersion. In specific situations for which the footprint has to be minimised or for high structures, Reinforced Earth® dykes and levees, either with vertical or steep faces (ArmaGreen® and ArmaStone® solutions), are solutions with proper adaptation to site conditions.
Combined with deep in-situ waterproofing techniques, Reinforced Earth® MSE embankments become efficient geo-barriers. This applies to new built structures and also to the raising of existing structures.
The TerraDyke™ concept developed by Geoquest is a customised engineered solution particularly well adapted to the construction of dykes. This state-of-the-art technique is based on the use of geotextile tubes which constitute the core of the dykes. It is a soft solution offering the advantages of geosynthetic materials and site won fill materials.
When basal reinforcement is necessary due to the nature of the foundation soil of the structures, ArmaLynk® and ArmaGrid® geogrids will provide the right answer.
Our geosynthetic products provide the solutions to cope with the commonly met issues as far as filtration and separation (TerraTextile™), erosion protection (TechRevetment™, TerraGreen™, ArmaWeb®), drainage (TerraFlow™) and waterproofing (TerraLine™ GCL) are concerned.
Flood control structures
Our Reinforced Earth® MSE walls as well as our ArmaGreen® and ArmaStone® steep slope solutions represent a proven alternative to other construction methods and materials used to build flood control structures. MSE structures present the inherent advantages of economy, flexibility and speed of construction. When working in cut conditions, T-Wall® and TechWall™ precast retaining walls are convenient solutions.
Our precast concrete arch provide similar benefits for the construction of water conveyance tunnels.
