SEL Permavoid® units are High Strength Highly Voided (95%) Polypropylene structures which are designed to Replace Sub-Base. The Inherent Strength of the SEL Permavoid® units allows Shallow Installation so a Rainwater Harvesting Tank can be sited almost anywhere, for example Beneath Car Parking areas, Under Roads etc.
The Flexibility of the Althon SEL Rainwater Harvesting System allows the Tank to be constructed to any Shape or Size, allowing it to Avoid any Buried Services, Building Foundations etc. The Flexibility and Robustness of the System also makes it Ideal for Retrofit.
Collected Rainwater can be Stored in a Standalone Attenuation Tank constructed from SEL Permavoid® units Encapsulated in an Impermeable Fully Welded Membrane. Alternatively tanks can be linked to the Althon SEL Source Control System.
