The BLANKE DRAIN-Mat provides a durable, prefabricated drain system to prevent the accumulation of moisture that can form hydrostatic pressure and damage floors. Moisture is allowed to seep down through water-permeable fabric on top into channels formed between pillars in the system’s high load-bearing PVC base. The water drains by natural gravitational force to designated outlets. It reduces the potential for damage caused by water expansion in freeze/thaw conditions.
- appropriate for the installation under gravel beds, on columns or mortar bags, or in the thick-bed method for the capillar-passive drainage
- fast and durable drainage
- no deterioration underneath the surface covering
- superior compressive strength up to 22 t/m2
- no deformation up to a temperature of +80° C
- protects the substrate waterproofing by its smooth plastic bottom
