PM TERRA-TEC is the optimum solution for horizontal and vertical applications.

Protects underground car park ceilings, terraces, green flat roofs and external cellar walls against backwater, stratified and seepage water. For new construction and renovation, on all pressure-resistant substrates.

PM TERRA-TEC consists of a special dimpled sheet with 11 mm high, reinforced and trowalised dimples, which are rounded at their edges. These advantages contribute to the excellent water drainage capacity and compressive strength. In addition, the extremely dense dimple density ensures that the load is distributed particularly evenly over the entire surface of the waterproofing - and thus a waterproofing protection that perfectly prevents point loads.

PM TERRA-TEC has an outstanding compressive strength of 500 kN/m². The drainage sheet is available in many different length and width variations. The optimum water drainage capacity is many times higher than required by the drainage standard DIN 4095. The moisture passes through the geotextile into the dimpled channels and is safely drained off there. The geotextile acts as a filter and prevents the dimpled channels from clogging up. The optimum high-performance geotextile has a very high initial strength and is characterised by only minimal deformation under increasing service load.

The new click dimples fastening system of the overlap edge is simple and practical. It works according to the click-button principle - in any weather and independent of temperature, even in winter. PM TERRA-TEC can be processed much more safely when laid horizontally because the sheets can no longer be blown up by wind.

With a height of 11 mm, the drainage sheet ensures a flat structure. The laid drainage membrane can be driven over directly with a wheelbarrow; if the ground has been filled out at least 20 cm beforehand, PM TERRA-TEC can also be driven over with wheel loaders.

PM TERRA-TEC is also a quiet whispering drainage sheets, because the tested impact sound reduction, in accordance with DIN EN ISO 10140, is ΔLw = 26 dB for uninsulated terrace structures and even up to ΔLw = 34 dB for insulated flat roof structures.

PM TERRA-TEC is available in 7 widths (up to 2.5 m) and 3 lengths (12.5, 15 and 20 m). The maximum width of 2.5 m allows an extremely fast installation time, especially for horizontal applications.
