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 85S unit.
