A structural module (10) for use in water irrigation, water drainage, water retention and water filtering systems, comprises a load bearing base unit (10) and porous material (15), wherein the base unit has a top wall (11) and a bottom wall (12) spaced therefrom by one or more supporting elements (13, 20) so as to define a volume between the top and bottom walls. The base unit being provided with apertures (17, 18, 19) to permit the flow of liquid into and out of the volume. The porous material is a block (15) foamed polymeric material which occupies a substantial portion of the volume within the base unit and absorbs and retains water that passes through the apertures.
A structural module comprising a load bearing base unit and porous material, wherein the base unit has a peripheral wall and a top wall and a bottom wall spaced therefrom by one or more supporting elements so as to define a volume between the top and bottom walls, the base unit being provided with arrays of apertures in the peripheral wall and top wall to permit the flow of liquid into and out of the volume, and wherein the porous material is a foamed polymeric material which occupies a substantial portion of the volume within the base unit and absorbs and retains substantial quantities of water that pass into the enclosed volume through the apertures.
