Economical three-layer protective and drainage membrane for installation depths up to 7 m.
DELTA®-X DRAIN can be used on pressure-sensitive surfaces, for example polymer-modified bitumen thick coatings (PMBC, formerly known as KMB).
Due to its compressive strength, the membrane can be used at an installation depth of up to 7m and with its high drainage capacity even with high water loads.
Also the usage as methane gas and radon drainage is possible.
The processing can be done either parallel or perpendicular to the top of the terrain. Always make sure that the printed geotextile points to the ground or backfill material.
The overlapping of two sheets on the long sides must be carried out by means of the one-sided smooth edge. In case of transverse joints, the lower sheet must be laid at least 20 cm under the upper sheet.
