Permavoid® Water Source Control

Preliminary Water Control and Storage System

Permavoid 150 is a 150mm thick modular interlocking plastic storage system designed for use as a combined drainage component and sub-base replacement system. It has exceptionally high compressive strength and bending resistance within joints and creates a horizontal structural ‘raft’ within the pavement that is ideal for the shallow attenuation and conveyance of stormwater.

ABT Permavoid® underground storage systems are designed to manage stormwater at the source allowing for simultaneous storage and controlled conveyance, helping nearly any site to turn stormwater from a waste product into a valuable resource. Source Control in stormwater management is the most cost effective means for the urban environment. With ABT Permavoid® there is no need to pay to move water, haul soils and clean stone. The modules have a very high void ratio (95%) providing highly efficient water storage capacity. The robust design of Permavoid utilizes proprietary engineered recycled plastics and patented mechanical keys that enable a direct paving course with minimal cover in an environmentally friendly manner.

Features for Sports Field Applications

Minimal Excavation

  • Minimizes excavation and transportation of poor soils and clean aggregate
  • Replaces drainage stone / sub-base
  • Very high (95%) void ratio
  • One truckload of Permavoid is equivalent to 21 truckloads of spoils and stone

Provides a High Strength Rigid “Raft” for Construction

  • Robust Structure for Ground Stabilization for sites where subsidence and unstable soils are an issue

Stormwater Attenuation – “Source Control”

  • Low Impact Development (L.I.D.)
  • Preliminary Stormwater Control
  • Slow & Controlled Release

Elimination of Collector Pipes and Associated Excavation

Stormwater Infiltration

  • Large Surface Area to depth ratio provides exceptional infiltration performance

Mechanical Keys

  • The interlocking components create a monolithic structural slab that’s not only perfect for synthetic turf sports fields, but handles demanding vehicular loads
  • Unique jointing system provides creep resistance (Permatie)

Environmentally Friendly Product

  • Manufactured from Recycled and Recyclable Material

Lightweight and Easily Handled and Installed on Site (6.62 lbs. per unit)
