Special features
A variety of innovative water products.
Capillar
Mimicking nature with capillary action.
Recycling
100 procent recycled and ready to be reused.
The Permavoid 170s is delivered in panels of 3m2 for quick and easy installation.
Connectors
Better performance with the connectors.
In combination with the Permavoid Capillary Cylinders the system can be used in water sensitive urban design, enabling stormwater attenuation, retention, infiltration, conveyance and natural capillary (plant) irrigation without the use of energy, pumps or in-building water storage tanks. The PermaLock enables you to create a sturdy connection for everything you would want to attach to the Permavoid 170S unit. The PermaLock is inserted into the unit at any of the openings and secured with a bayonet lock. The PermaLock houses a standard 8 mm (5/16”) steel thread, in which bolts can be screwed to attach for example fencing, solar panel systems or wooden decks.
