Features & Benefits

• Protection and drainage system made from high-density extruded polyethylene (HDPE) laminated with a polypropylene needle-punched nonwoven
• Particularly effective in protecting waterproofing of below grade structures or earth retaining structures in general, also providing excellent drainage capacity
• The structure and geometry of the studs give extremely high mechanical performance, ensuring perfect ventilation and excellent water drainage
• Designed to provide the waterproofing membrane with suitable protection during foundation backfilling work
• Polypropylene nonwoven ensures excellent water filtering and drainage capacity, enabling effective vertical and horizontal drainage
• Ideal for application where the waterproofing of retaining walls, below grade structures and foundations requires both protection and drainage, and is also ideal for drainage in lightweight roof gardens

Application

Vertical application on below grade structures or earth retaining structures:

• Can be applied on retaining walls by pre-cutting the geocomposite to the desired size, allowing for the fact that it must also cover the drainage pipe previously set in place and covered with medium-grade washed river gravel
• Place kit drain with the nonwoven fabric side facing the backfill and the smooth side facing the waterproofing layer on the wall to be protected
• The edges of kit drain - the mechanical protection and drainage layer - must overlap by approx. 20 cm
• On vertical walls, product must be fixed mechanically to the top of the wall
• In addition to fastening the product, the mechanical fixing must also fasten the top of the membrane forming the wall’s waterproofing system: this will be done with the aid of a polyethylene or metal profile with fasteners for concrete
• Polydetail MS sealant will then be applied between the profile and the concrete wall to seal the fixing

Horizontal application on roof gardens with no reservoir:

• When creating roof gardens, the drainage layer can be produced by laying the product directly on top of the waterproofing build-up with the filtering nonwoven side facing the growing medium
• Drainage must be produced both on the flat part of the garden and along the vertical turn-ups around the outside edges with no break
• Product must be overlapped by at least 10 cm on the sides and approx. 15 cm on the ends, exercising great care while backfilling that the growing medium does not lift the overlapping edges, ending up between the two drainage geocomposites
• The growing medium must be positioned and laid immediately after the kit drain has been installed
