CIRIA has produced Guidance Document C680 "Structural design of modular geocellular drainage tanks". This document has been produced to ensure that engineers have the required information to establish that a proposed underground structure is capable of remaining structurally sound and operational in trafficked situations over the lifetime of the construction.
C680 asserts that engineers should satisfy themselves of the suitability of the proposed construction, and not rely on manufacturer's recommendations.
SEL Permavoid has been fully tested in accordance with the requirements of C680 and we can, if required, provide structural calculations for SEL Permavoid tanks within our designs from an independent consultant. For further information on C680 see the CIRIA website or contact the Althon sales office.
