Abstract

A safety surface material for a playground facility employing a monolithically mixed and trowelable thermoplastic olefin urethane cushion base course layer—which, for water park/spray park use is overlain by a thermoplastic rubber wear top course layer that is both light stable and chlorine resistant.

Claims (15)

1 . A recreational facility substrate surfacing material comprising:

a cushion base course layer and an overlying wear course layer, wherein the cushion base course layer is characterized by having a chemical resistance to acids, bases and aqueous media, and exhibits a combination of stiffness, impact resistance and dimensional stability.

2 . The surfacing material of claim 1 wherein the wear course layer is composed of rubber or synthetic turf.

3 . The surfacing material of claim 1 wherein said cushion base course layer is a thermoplastic olefin.

4 . The surfacing material of claim 2 wherein the cushion base course layer is a thermoplastic olefin.

5 . The surfacing material of claim 1 wherein said wear course layer is characterized by having excellent abrasion and weather resistance and dimensional stability, is light weight, non-shrinkable and exhibits a meaningful tear strength.

6 . The surfacing material of claim 5 wherein the wear course layer is also ultraviolet light and chlorine resistant.

7 . The surfacing material of claim 6 wherein said cushion base course layer is a thermoplastic olefin.

8 . The surfacing material of claim 6 wherein said wear course layer is a thermoplastic rubber.

9 . The surfacing material of claim 7 wherein said wear course layer is a thermoplastic rubber.

10 . The surfacing material of claim 9 wherein said cushion base course layer is of a thickness of 2½″-4″.

11 . The surfacing material of claim 9 wherein said wear course layer is of a thickness ⅜″-½″.

12 . The surfacing material of claim 10 wherein said wear course layer is of a thickness ⅜″-½″.

13 . The surfacing material of claim 12 wherein each of said cushion base course layer and said overlying wear course layer are monolithically trowelable.

14 . The surfacing material of claim 1 wherein said cushion base course layer is a thermoplastic olefin with a urethan binder.
