High Quality Dimpled Sheets made by INTERPLAST.

ISO-DRAIN 8 GEO

Protective Drainage Sheet
for Foundation Walls

Dimpled Sheet ISO-DRAIN 8 GEO
ISO-DRAIN 8 GEO dimpled sheet from INTERPLAST provides out-
standing drainage and physical protection over underground foun-
dation walls. The nonwoven geotextile mat over the dimples creates
a continuous air gap for reliable ventilation and drainage of water in-
flow from the surrounding soil. This composite system excels in a wide variety of other application sectors as well including basements, underground parking garages, roof terraces, parking garage roofs, etc.
Benefits: ISO-DRAIN 8 GEO
  • Permanent air gap, suspended particles in water are filtered out by the geotextile mat
  • Excellent drainage performance
  • Outstanding compressive strength (250 kN/m²)
  • Superior physical strength and elongation properties
