PM STANDARD GS dimpled sheet with 8 mm high dimples is the high-quality problem solution for foundation wall protection and the sub-base course. These PMI dimpled membranes are made of high-quality low-pressure polyethylene (HDPE). HDPE is groundwater-neutral, free of pollutants in disposal and recyclable. The dimpled membranes are used to protect perimeter insulation and on sufficiently pressure-resistant waterproofing. Thanks to their very good compressive strength and elongation at break, PM STANDARD GS dimpled membranes offer reliable protection when filling the excavation pit. The dimples reliably separate foundation wall and soil and are also a cost-effective alternative to sub-base course of lean concrete.
PM P-STANDARD GS is a water-storing perforated variant of the dimpled sheet and is considered the ideal solution for extensive green roofs, including inverted roofs. PM P-STANDARD GS offers good drainage and water storage capacity compared to normal dimpled membranes and acts as a protective and water storage layer in green roofs. The 8 mm dimples have a water storage capacity of approx. 3 l/m². The compressive strength of approx. 250 kN/m² offers a high degree of safety and thus corresponds to approx. 25 tonnes of compressive load per m². The 8 mm dimpled sheet also offers a good horizontal drainage capacity.
PM P-STANDARD GS-GEOTEX is a product variant with an integrated geotextile on the upper side. The plant substrate can be applied directly, which saves an additional work step.
