Product Description

10mm height drainage composite sheet for roof garden

Product Description

Drainage composites can replace up to 1 foot (300 mm) of drainage gravel in some applications. Unlike drainage gravel, a drainage board can be placed vertically and even suspended overhead to make complex drainage problems much easier to solve. Drainage board is most often used in commercial building applications where positive drainage is required, and space is limited. This typically occurs in commercial building foundations, underground parking lots, and tunnels but can also be used for residential applications. The drainage board composite offers excellent water transmissivity in an exceptionally thin layer. This allows designers to maximize available real estate and place building foundations closer to property lines. In applications where property lines require vertical excavations, a drainage composite may be the only way to ensure drainage. Drainage boards are available with different core strengths and geotextile filters.

Features

  • Provides positive drainage in a thin section
  • Easily placed on exterior foundation walls
  • Can be inspected prior to backfilling operations
  • Geotextile fabric prevents clogging of the core
  • High compressive strength

Applications

  • Building applications where drainage space is limited
  • Building foundation repairs and waterproofing
  • Gas venting and gas monitoring vents
  • Underground cut off curtains
