Claim 5:
6. A method for forming a surface water mitigation structure on a ground surface, said method comprises:
a) forming a cavity, said cavity is at least about 3 inches deep;
b) depositing particles of a porous storage medium in said cavity;
c) preparing a mixture of materials for use in forming a permeable rigid composite; said mixture of materials including a base material and a binder; said base material in said mixture is at least partially wetted by said binder by mixing said binder when not fully cured with said base material; said base material includes first particles and second particles; said first particles selected from the group consisting of limestone, shale, slate, sandstone, quartz, feldspar, dolomite, obsidian, mica, diorite, flint, granite, glass, concrete, expanded shale, and expanded slate; said second particles selected from the group consisting of rubber, recycled asphalt and recycled plastic; an average particle size of said first particles and said second particles is 3-30 mm; said base material constitutes 55-99.5 wt. % of said permeable rigid composite; said binder constitutes 0.5-45 wt. % of said permeable rigid composite; said first particles and said second particles are formed of different materials; said binder includes 80-100 wt. % of one or more materials selected from the group consisting of epoxy, urethane, styrene, butadiene, and silicone; said first particles constitute 20-80 wt. % of said permeable rigid composite; said second particles constitute 20-80 wt. % of said permeable rigid composite; said binder at least partially binding together said base material once said binder is fully cured; a total weight of said base material and said binder constitutes about 90-100 wt. % of said permeable rigid composite;
d) pouring said mixture of materials over a top surface of said porous storage medium; said binder not fully cured when said mixture of materials is poured on said top surface of said porous storage medium;
e) spreading said mixture of materials over said top surface of said porous storage medium prior to said binder being fully cured to form a flat a top surface of said mixture of materials;
f) allowing said binder in said mixture of materials to fully cure to form said permeable rigid composite; said binder at least partially binding together said base material once said resin is fully cured; said permeable rigid composite has a composition and thickness to support a load on a top surface of said rigid and permeable composite capstone layer of least 300 lbs/ft.2 without breaking under such load and has a deflection under such load of less than 5%; said permeable rigid composite porous to water to enable surface water on a top surface of said permeable rigid composite to flow through said permeable composite rigid capstone layer and into said porous storage medium; said permeable rigid composite configured to allow water to pass through said permeable rigid composite at a rate of at least 0.25 inches of water per square foot per hour; a thickness ratio of said permeable rigid composite to said porous storage medium is at least 1:1.2; said permeable rigid composite having a thickness of 0.1-5 inches; and
g) impregnating said porous storage medium with remediating agent by pouring a solution of said remediating agent onto a top surface of said permeable rigid composite and allowing said solution to penetrate through said permeable rigid composite and into said porous storage medium; said solution of said remediating agent poured into said top surface of said permeable rigid composite after said binder has fully cured; said remediating agent constituting 0.1 vol. % to 40 vol. % of said porous storage medium after said porous storage medium has been impregnated with said remediating agent.
