Permavoid Surface Drainange

Permavoid

Environmental, LID and Stormwater Systems

ABT Permavoid is a modular interlocking plastic system designed for use as a combined drainage component and sub-base replacement. The system has exceptionally high compressive strength due to it’s engineered co-polymer polypropylene structure. The proprietary jointing system provides maximum bending resistance creating a horizontal structural ‘raft’ within the pavement allowing for the dissipation of heavy traffic loads to even poor subgrade soils. Both PV-150 and PV-85 are ideally suited to provide conveyance, detention and LID source control of stormwater all within an ultra shallow envelope.

Key Features

Permavoid can be easily modeled with the HydroCAD Stormwater Modeling system, allowing simplified analysis of its behavior in a drainage and stormwater management system. HydroCAD includes custom rating curves for these devices, which can be used with the “special outlet” capability to easily define its stage-discharge characteristics.

Tree Protection Full System:

Collection, Treatment & Storage. Protect valuable infrastructure from damaging tree roots while simultaneously promoting tree health and vitality. Permavoid provides positive air circulation and stormwater infiltration into the root zone of new or developing trees.

Subbase Replacement Full System:

Collection, Treatment & Storage. Replace up to 18 inches of aggregate subbase and 12 inches of excavation while managing stormwater within Permavoid.

Passive Irrigation Full System:

Collection, Treatment & Storage. Reduce or eliminate irrigation expenses by utilizing stormwater. Control the volume of stored water to maximize the health and vitality of grass or other plant material.

Bioswale Outlet Full System:

Collection, Treatment & Storage. Reduce the size and quantity of bioswales by maximizing the performance of each. Store water in Permavoid for controlled discharge to maintain ideal water depths.

Bioswale Inlet Full System:

Collection, Treatment & Storage. Maximize the natural behavior of rainfall while reducing runoff volumes. Combine bioswale infiltration and passive irrigation to store water where it’s needed most and eliminate the costs to move stormwater.

Key Applications

POLYDRAIN

NFPA Requires nonflammable trench drains

Life Safety Choice

Selecting a fire resistant trench drain system should be common practice for any interior application. Trench Drains are often the collection points for flammable fluids and heavier-than-air vapors. As a result, even empty trenches can act as a pathway for flame spread. For more info, see our Flame and Smoke page.
