ISO-DRAIN nature 15 – new variants for designing outdoor spaces that satisfy technical standards

Whether roof terraces, balconies, fire access routes for underground parking facilities or parking decks, modern outdoor spaces need to be designed to meet strict requirements when it comes to drainage, load-bearing and compliance with technical standards. Thanks to the new ISO-DRAIN nature 15 M, 15 MP and 15 GP variants, we can now offer you even more practical surface drainage solutions that provide reliable functionality for the long term.

All the products satisfy the requirements for accessible transition points set out in BTI 1.4 (Germany) and SIA 271 (Switzerland), are ideal for use under outdoor walk-on and drive-on surfaces and feature a low installation height.

Here’s a brief overview of the new variants:

  • ISO-DRAIN nature 15 M
    With reinforcing mesh – ideal for use with drainage mortar to achieve robust and durable surfaces.
  • ISO-DRAIN nature 15 MP
    Perforated for vertical drainage – quickly channel away rainwater and melt water.
  • ISO-DRAIN nature 15 GP
    Perforated and with geotextile filter and barrier layer – perfect for surfaces that are exposed to high mechanical stresses.
  • Passive capillary effect and stability under pressure
  • Reliable drainage in all weather conditions
  • Dependable installation – standard-compliant & practical
