Isocor

ISOCOR is a drainage geocomposite consisting of a thermoformed geospacer with a symmetrical, impermeable and non-compressible honeycomb structure, coated on one side with a geotextile.
The purpose of Isocor is toevacuate seepage or groundwater to a drainage collector, and to mechanically protect the waterproofing layers. It fulfils three essential functions to ensure the longevity of the structures:

• stop and evacuate seepage water or water present in the ground, thus reducing hydrostatic pressure on buried walls
• maintain an air gap along the walls
• protect waterproofing layers from mechanical damage, particularly during backfilling.

Its true performance lies in its ability to maintain a high flow rate when under stress, while protecting the structure. Finally, Isocor has an impermeable structure that allows concrete to be projected or poured directly (lost formwork).
