Advanced Sub-Surface Dewatering System
Power Drain has been brilliantly designed to use capillary forces and syphonic action to drain water from soils far more effectively than simply relying on gravity. Power Drain is a unique flat belt made up of special thermoplast PVC compound with a collection of tubes placed underneath the belt. When laid on the soil, the capillary action in the soil helps to move the water towards the omega-shaped tubes found underneath the belt.
The unique design of Power Drain helps to hold the water within the grooves due to the forces of adhesion, cohesion and surface tension. The collected water is then guided to GeoRex pipe, our subsoil drainage specialist, with the help of a coupler which is designed to insert the Power Drain belt into the GeoRex Pipe.
The GeoRex pipe is installed at a lower level than Power Drain to create a siphonic movement, making it an active drainage system. The perforated surface of the GeoRex pipes in combination with Power Drain creates a double action drainage system. Not only does it help to drain excess water from the soil, but also helps in directing the water toward storage.
