Drainage Composites

Drainage composites are used in conjunction with waterproofing membranes to provide protection and drainage. They consist of a polystyrene core covered with a filter fabric. The fabric allows water to filter through while keeping the soil out. Drainage composites reduce hydrostatic pressure and promote positive drainage. Drainage composites are available in numerous thicknesses and strengths as well as horizontal and vertical grades.

Drainage composites may be applied on horizontal or vertical structures including, but not limited to, the following:

  • Roof decks
  • Plaza decks
  • Split slab applications
  • Vertical foundation walls
  • Tunnels
  • Planters
  • Lagged foundations walls
  • Retaining walls
