WAL Drain-Tec 250 | External Drainage and Protection Waterproofing Membrane

PM DRAIN-TEC 250 is an effective protection and external drainage membrane that is
the universal solution for both horizontal and vertical surface drainage
on all pressure-resistant surfaces. PM DRAIN-TEC 250 consists of
a dimpled membrane and a sturdy geotextile. The smooth back side
allows for a uniform and extensive load distribution on the seals.
This double-layer system protects the primary waterproofing from mechanical
damage upon backfilling. PM DRAIN-TEC 250
has a compressive strength of 250 kN/m2.
