Draining underground structures is an integral part of the lining systems. An effective and reliable drainage system prevents water penetration and development of hydrostatic pressure.
Multilayer drainage mats form effective and rapid vertical/horizontal channels for transporting surplus water.

 

Vertical drainage:


Drainage alongside underground structural walls, basements, parking garages, tunnels, as well as drainage alongside retaining walls.

Horizontal drainage:


Under paved surfaces / soil layers, atop underground basements, green roofs, etc.

Drainage and lining of posts:


Variable width drainage strips are installed between piles to serve as a drain protected from cast concrete and permitting effective drainage of pile walls.

Drainage of green roofs

Green roofs are an important element in a green/ecological building which bring to energy savings, Green roofs are an important element in a green/ecological building which bring to energy savings, reducing air pollution and/or noises. Increasing the green areas allows an animal cushion.

Building a green roof requires a water drainage system over the sealing layer. Drainage mats include a protection layer of the roof’s waterproofing system and prevent mechanical or physical damages. The drainage mats allow effective and measured water transportation to the drainage system.
