The high load, capillary passive surface drainage system
for loose laying on unbound substrates and for wood coverings.
AquaDrain® HU is a high-load but at the same time capillary passive surface drainage mat – developed especially for loose laying on unbound substrates. Unlike conventional dimpled membranes, AquaDrain® HU is perforated on the underside: even on rough ground, seepage water can flow away.
