Abstract:
A form into which concrete may be poured for the formation of grid pavement in situ is comprised of a sheet base having top and bottom surfaces, the top surface having a plurality of hollow frusta projecting there from preferably in a uniform pattern and creating an interstitial space there between within which a first site material, namely concrete, is poured to create a grid with areas and a second site material, namely soil, sand or an aggregate, occupies the frusta and is in communication with the underlying subsoil. In order to prevent wet concrete from infiltrating the hollowed frusta during pouring of concrete into the interstitial space, lids of a preferably biodegradable substance such as compressed peat are inserted into or over the frusta openings. The lids may be easily broken into pieces which fall into the hollowed frusta after the concrete has cured so that the second site material can be added therein. When the second material is soil, the peat will increase the soil's capacity to retain moisture and add nutrients promoting vegetation growth. Removable lids are also contemplated.
