A method of constructing a drainage surface for a drainage area having a defined drainage point, the method including:
- (a) defining the drainage area;
- (b) defining the drainage point within the drainage area;
- (c) taking a plurality of uniform support members, each support member comprising a planar unit and including one substantially flat surface and an opposite drainage surface forming a slope from an outer region at which the unit is thicker to an inner corner at which the unit is thinner, the plurality of support members capable of forming a substantially continuous drainage surface when the inner corners adjoin the drainage point, and wherein the support members are formed from rigid polyurethane foam;
- (d) if required, cutting or shaping outer regions of the support members to fit the defined drainage area;
- (e) positioning the support members in the defined drainage area to form a substantially continuous drainage surface;
- and
- (f) forming a seal over the support members.
A kit of parts for constructing a drainage surface for a drainage area having a defined drainage point, said kit of parts including a plurality of uniform support members each support member comprising a planar unit and including one substantially flat surface and an opposite drainage surface forming a slope from an outer region at which the unit is thicker to an inner corner at which the unit is thinner, the plurality of support members capable of forming a substantially continuous drainage surface when the inner corners adjoin the drainage point, and wherein the support members are formed from a rigid foam material with a density from about 80 to about 200 kilograms of chemical per cubic meter of final product.
A support member for supporting a drainage surface drainage area having a defined drainage point, said support member comprising a planar unit and including one substantially flat surface, an opposite drainage surface forming a slope from an outer region at which the unit is thicker to an inner corner at which the unit is thinner, and edges extending from the inner corner to the outer region, each edge adapted to abut or interengage with a corresponding edge of an adjacent support member to extend the drainage surface in a substantially continuous manner, and, said inner corner having an angle divisible into 360°, and wherein the support member is formed from a rigid foam material with a density from about 80 to about 200 kilograms of chemical per cubic meter of final product.
