Our hybrid geodrains sheets which are in various designs are made of a net of porous or non-porous HDPE sheets covered on one or two sides with geotextile, are veritable more competitive alternatives to the conventional methods of drainage and lowering of water tables. They could be used in foundations, basements, retaining walls to either water-proof and/or drain or protect the structures. They serve other purposes of reducing pore pressures, guide against chemical contaminations, corrosion, and allow backfilling with non-graded materials.
