DELTA-TERRAXX "Berlin type"

Application

Use a knife to cut the sheet to size across its width. Install the sheet so that the cloth-covered side faces the soil. Attach the sheet approximately 10 cm above the upper edge of the waterproofing layer.

After backfilling, trim the sheet in parallel with the surface of the soil and protect it with DELTA®-NOPPENBAHNEN-PROFIL. At the bottom, the sheet should end at the drain pipe.

DELTA®-TERRAXX may also be attached to perimeter insulation boards, which in this case must be safely glued to the foundation wall coating. Use at least 1 DELTA®-TERRAXX-SCHRAUBE per square metre and screw it through the sheet into the insulation board.

When installing a sheet, push its edge underneath the smooth overlap edge of the sheet installed previously. Remove the covering strip from the adhesive Tape and glue the two dimpled sheets together

When light wells have already been installed, cut the sheet precisely along their lower edge and make one vertical cut in the middle.

When DELTA®-TERRAXX is applied to perimeter insulation boards, protect the upper edge withDELTA®-TERRAXX-PROFIL

Material

A studded membrane made of special, high-density polyethylene and PP non-woven fabric.

Properties

DELTA®-TERRAXX is an ideal filtration and seepage layer for “Berlin” timber walls.
Sheets should be installed so that the filtration cloth faces the timber wall.
Their self-adhesive overlap zones prevent cement sludge from entering and clogging up the seepage layer when concrete is poured.
