Claim 0:
1. A method for forming a surface mitigation structure that can be use in an animal stable floor, animal stall floor, or animal shelter floor; said method comprises:
a) digging up a ground surface in said animal stable floor, said animal stall floor, or said animal shelter floor to create a ground cavity at least 3 inches deep;
b) depositing particles of a porous storage medium in said cavity to form a porous storage medium layer; said porous storage medium comprising a water-absorbent material;
c) inserting a support layer on or above a top surface of said porous storage medium layer; said support layer formed of I) a permeable rigid composite; said permeable rigid composite includes a mixture of base material and binder; said base material including first particles and second particles; said first particles and said second particles formed of different materials; said permeable rigid composite having a composition and thickness to support a load on a top surface of said permeable rigid composite of at least 50 lbs/ft.2 without breaking or cracking under such load; said base material constituting at least 55 wt. % of said permeable rigid composite; said binder constituting at least 5 wt. % of said permeable rigid composite; a total weight percent of said base material and said binder constitutes 90-100 wt. % of said permeable rigid composite; or II) a support material including a plurality of openings there through; an average size of said plurality of openings is less than said average particle size of said porous storage medium layer; and,
d) inserting a porous flexible layer on or above a top surface of said support layer; said porous flexible layer configured to allow water to pass through said porous flexible layer at a rate of at least 0.25 inches of water per square foot per hour; said porous flexible layer having a thickness of at least 0.1 inches; said porous flexible layer formed of a different material than said support layer; said porous flexible layer having a flexibility that is at least 30% greater than a flexibility of said support layer.
