RoofDrain ST12 - Multifunctional drainage mat - Matgeco

RoofDrain ST12 is a drainage mattress made up of a three-dimensional structure of needle-punched polypropylene fibers whose unique and exclusive assembly forms small drainage channels.

This mattress is covered and assembled with a non-woven polyester geotextile of ±150 g/m² serving as a drainage filter .

The new RoofDrain ST12 is lightweight , easy to place and accessible to wheeled construction machinery .

  • It evacuates excess rainwater .
  • It offers good mechanical protection .
  • It allows a water retention of ±6 l/m².

Horizontal drainage of green roofs – extensive and intensive:

Horizontal drainage of green roofs – extensive and intensive

Roofdrain ST12 evacuates excess rainwater in a controlled way and allows the execution of a continuous draining structure. Its water retention capacity (±6 l/m²) ensures optimal plant development while evacuating excess water in a controlled manner.
Its structure and high density provide security against puncturing and protect the seal during installation and maintenance of the green roof. Its low weight avoids overloading the supporting structures.
In addition, it is passable to construction machinery on tires during the implementation of the substrate or the topsoil. The geotextile on the upper side filters the fines and allows the water to pass through. A lateral covering without extra thickness will be ensured using the overhanging geotextile. It will be covered with earth or substrate with a view to creating an intensive garden or extensive plant roof.

Horizontal drainage under paving – terraces:

Horizontal drainage under paving – terraces

Roofdrain ST12 is ideal for the horizontal drainage of terraces on concrete slabs or waterproofing. It is unrolled with the non-woven geotextile side up, respecting its lateral overlap.
It will be covered with a lean or stabilized concrete of at least 7 cm before the laying of the final covering (paving, pavers, etc.).

Benefits :

  1. Ultra-efficient drainage.
  2. Excellent water retention.
  3. Mechanical protection.
  4. Lightweight – quick installation.
