Dam walls & slopes
Geocomposite solutions can be specified for dam slopes where overspill capacities are to be increased to cope with storm events. In such cases Reservoir Panel engineers require a drainage system to increase the stability of the regraded spillway embankments and to provide drainage to the depth of fill to be placed.
In summary Drenflex options can provide efficient filtration without clogging and to prevent piping, alongside adequate flow capacity to channel rainfall and the anticipated seepage during the product’s design life.
Basin & Open-air reservoir construction
Reservoir linings are subject to large pressures from the head of water acting on it when the basins are full. In order to achieve the required design life of the reservoir and geomembrane, it is essential to protect the integrity of the lining system. A high performance geotextile layer is used to protect the geomembrane against any damage or puncture and provide separation between the liner and the underlying formation.
Slope Erosion Control
Permanent and degradable erosion control mats are also available for dam slope construction in order to protect fill from slipping / slump before grass is able to establish.
Erosamats Type 1 biodegradable coir offers temporary protection and by absorbing the impact energy of rain bombardment and reducing surface water run-off velocities they give the newly establishing vegetation the best possible chance of survival.
Erosamat Type 3 works by providing an interlock for vegetation root systems, better enabling the vegetation to resist high shear/stress situations. It is non-biodegradable and has a design life of 120 years.
