The unique four-layer protection and drainage system for installation depths of up to 10 m. With integrated self-adhesive edge.
DELTA®-GEO DRAIN QUATTRO was already developed and used for permanent waterproofing in 1993 for the special use on pressure-sensitive surfaces, for example polymer-modified thick bituminous coatings (PMBC, formerly known as KMB) and guarantees a constant protection of the seal.
Due to its high compressive strength, the membrane can be used at installation depths of up to 10 m and thanks to its large drainage capacity it can handle even extremely high water loads.
It can also be used as methane gas and radon drainage.
The processing can be done either parallel or perpendicular to the top of the terrain. It must always be ensured that the printed geotextile faces the soil or backfill material.
Overlaps of two membrane tracks on the long sides is done with the help of the self-adhesive edge. In case of transverse joints, the lower sheet must be laid at least 20 cm under the upper sheet.
DELTA®-GEO-DRAIN QUATTRO can also be used for horizontal applications.
