Water-retention and drainage board

PRODUCT CODE: 310234 Categories: ,

Advantages

  • Protecting the waterproofing against the scattering of the filling material ⇒
    protective overlapping edge around the board
  • Increased contact surface ⇒ heightened protection of the waterproofing through the favorable weight distribution
  • Vapor diffusion for inverted roofs ⇒ increased diffusion openings both side
  • Durable and high compressive strength material (HIPS) ⇒ no water cooling needed during summer installations
  • Preventing the sinking of the filter layer ⇒ dedicated support cones
  • Suitable for flooded blue roof ⇒ up to 100 mm water level with the combination of DiaDrain-60H rainwater retention board as a DiaDrain-120-WM wassermanagement system
  • Fire classification regarding EN 13501-1 ⇒ classified as class „E“ construction product, therefore without limitation applicable
