摘要	A rigid cell like structure primarily for use under gardens and roads where it is required to provide good drainage; the cell comprising two substantially parallel perforate planar surfaces maintained in a fixed spaced relationship from each other by means of a plurality of spacer members; the perforate nature of both surfaces and the disposition of spacer members being such that gases or liquids may freely pass through the composite structure around the spacer means in any direction.
