Volume storage
With the structural modular Permavoid MD cells we are able to build underground waterstorage tanks into any volume or shape.
Permavoid MD for deep applications
The tried and tested Permavoid MD range is designed to provide surface water retention, surface water attenuation or surface water infiltration at a variety of depths.
The Permavoid range of modular cell systems are designed with a 95% void ratio to retain large volumes of water run-off. The Permavoid MD modular cells can be built up to form a structure of any shape or size making them ideal for narrow strips or restricted areas. The modular cells have unique rounded corners which enables ease of handling and reduces the likelihood of punctures to membranes. The range can be designed for both trafficked and non-trafficked areas. At the end of their life the modular cells are fully recyclable. Permavoid MD is produced from 100% recycled polypropylene. The perfect blend of technology and sustainability.
Create formule with volume storage
With the structural modular Permavoid MD cells we are able to build underground waterstorage tanks into any volume or shape, without losing the use of land above the tank due to the high pressure resistance. This underground structure will attenuate or infiltrate the rainwater depending on choice of wrapping.
Strong benefits for the city.
The Permavoid MD units have integrated connection points for pipe and inspection points and can be incorporated in an integral water management system.
To be sure the water quality in the deep attenuation tank is clean enough to be safely infiltrated or reused, we developed an extra cleansing step in the MD unit: the floating mat. It traps any residual hydrocarbons and oils in the water.
The long and narrow design of the Permavoid MD tank aims at maximum surface area for rapid infiltration to groundwater.
The Permavoid MD units will arrive ready to install on-site, which will save expensive labour on site.
