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
