The drainage of water is one of the essential cornerstones of civil engineering design. In building construction, building components should not be in direct and permanent contact with water. In earthworks, the ingress of water from the surface or from aquifer water or groundwater should be avoided, since it can soften the soil layers or result in the accumulation of water.
Drainage is the term used to describe technical systems that allow water to drain away without pressure being applied. In order to drain the water in a controlled way, a separated permeable section is constructed. This should be more permeable than the surrounding material. Planar systems (area drainage) are differentiated from trench or pipe drainage systems. Planar drainage systems or layers can be constructed using permeable mineral materials or geosynthetics such as drainage grids, drainage mats and drainage membranes. For trench drainage and pipe drainage, mineral or plastic pipes can be used. Often a combination of planar and pipe drainage is required if the collected water is to be routed away from an area.
All products in the range Drainage system
BEDRAIN Drainage Grids
BEDRAIN Drainage Grids are pressure-resistant drainage grids made of high-density polyethylene (HDPE) with non-woven fabric bonded on one or both sides, specifically for use in drainage applications under high compressive loading.
BEDRAIN Drainage Mats
BEDRAIN Drainage Mats comprise a three-dimensional random arrangement of polypropylene (PP) monofilaments. They are used for drainage, as surface drainage systems, in green roofs, for foundation wall protection, in landfill sites and in tunnel construction.
BETEX TP Non-woven Fabrics
Non-woven fabrics are the archetypal geosynthetic. Depending on the structure and composition of the fabric, they can be used as a filtering, separation and/or protective layer in highway construction, buildings, civil engineering, gardens and landscaping.
Droptec Protection and Drainage Membrane
DROPTEC is a high-quality protection and drainage membrane with a bonded non-woven filter layer; for use in difficult drainage situations in intensive and extensive green roof systems on flat roofs. The protection and drainage membranes form part of the green roof system.
