Dimple board for wall drainage

InfraSheet Drain is designed to meet the specific needs of drainage behind concrete block walls, basements and retaining walls. They are widely used for vertical or horizontal drainage on piled structures, retaining walls, tunnel drainage, cavity drains, podium decks and soil bank stabilization.

InfraSheet Drain is lightweight, easy to handle and install in difficult access conditions, require minimal trench excavation and resist loads from infill and formwork.

InfraSheet Drain is installed with the geotextile facing the soil and the HDPE sheet up against the wall. They intercept seepage and transmit water into the core. When used for sub-surface drainage behind concrete walls InfraSheet Drain reduces the hydrostatic pressure against a wall or slab, maintains the structural integrity of the wall from grade to footer and reduces piping and erosion behind the wall. 

Other Benefits of Sheet Drains

  • Lower installed cost - Combined installation and material cost is usually less than half of that for aggregate drains.
  • Easy to handle and install - Lightweight
  • Reduces drainage system space requirements
  • Strong and durable - Crush strength of core resists damage during installation.
  • High flow capacity - Structure of core provides multiple channels for vertical and horizontal water flow. Geotextile filter fabric permits high volume of water into core while restraining soil.
