Wall drainage

ISO-DRAIN drainage geocomposites are used as one element of the foundation wall waterproofing system. They are used in conjunction with waterproofing and have two functions: to protect the main waterproofing layer and to create a drainage channel. ISO-DRAIN drainage geocomposites are equipped with a Typar geotextile filter fabric which is welded over the protrusions by thermal bonding, thus forming an air gap with high permeability. The material is placed with a filter layer (geotextile) against the ground. Water coming from the ground is filtered and diverted away from the building via a drainage pipe and into a drainage well, preventing it from accumulating dangerously close to the ground.
