High-load surface drainage
for drive-on coverings and wood coverings on balconies and patio terraces

AquaDrain® HB allows for reliable and permanent drainage of water from road and driveway coverings of paving stones or concrete slabs. Combined with drainage mortar or concrete, a surface drainage with high water shedding capacity is created, which can be driven on by cars and trucks. For road coverings of concrete or cement screed with a surface layer, AquaDrain® HB reliably removes excess water and  prevents the build-up of water vapour pressure by effective ventilation of the structure.
