A stabilized course sand bunker and method of making the same is disclosed. The soil making up the bunker is contoured and stabilized so that it is in the form of a pit having a downward angularly extending keyway surrounding the opening at the top edge of the pit. A semi-solid precursor material is applied over the pit and keyway and allowed to cure to form a barrier liner having a flanged anchoring portion for location under some additional soil and turf grass. Bunker sand is disposed over the barrier liner. The barrier liner when cured enables water in the bunker to pass through it, is sufficient flexible to dampen and absorb the impact of a golf ball strike, all the while stabilizing and protecting the edge of the bunker where the turf grass meets the sand in the bunker.

1. A stabilized golf course bunker in a desired configuration, said bunker being configured to be covered with sand and comprising: soil and a surrounding landscape in said desired configuration of the bunker having turf, an opening, a top edge, an angled keyway surrounding said opening at said top edge, an interior surface including downward sloping sides and a floor formed by compacted soil, and a hinge point located between said angled key way and said downward sloping sides, said turf surrounding said opening, said angled key way having a grade extending outward and downward from said opening, said angled key way extending underneath a portion of said turf surrounding said opening, said downward sloping sides having a downward sloping grade immediately adjacent said hinge point, said key way extending at an acute angle to said downward sloping grade of said sides inside said bunker, said turf being located above said angled key way and extending to said hinge point; anda barrier liner formed by a curable semi-solid barrier material applied on said floor, and with a portion of said barrier liner on said downwardly sloping sides, said portion of said barrier liner on said downwardly sloping sides having a thickness, said barrier liner also including a portion extending up and over said top edge for a predetermined distance on said angled key way and under a portion of said turf surrounding said opening of said bunker to include said hinge point between said top edge and said angled key way, said portion of said barrier liner overlying said angled key way having a thickness which is greater than the thickness of said barrier liner on said downwardly sloping sides, said barrier liner being configured to cure and thereafter be covered with bunker sand to complete said bunker, whereupon said barrier liner enables water to percolate therethrough to reduce water accumulation in said bunker and is sufficiently flexible to dampen or absorb impact when a golf ball hits said bunker. 2. The stabilized golf course bunker of claim 1, wherein said curable semi-solid barrier material comprises a mixture of a dry binding agent, lightweight aggregate and water. 3. The stabilized golf course bunker of claim 1, wherein said barrier liner includes an outer surface at said sides and floor and wherein said barrier liner additionally comprises a thin layer of finishing sand fixedly secured to said outer surface of said barrier liner at said sides and floor. 4. The stabilized golf course bunker of claim 3, additionally comprising loose bunker sand disposed over said thin layer of fixedly secured finishing sand. 5. The stabilized golf course bunker of claim 1, wherein said predetermined distance is approximately 4 to 6 inches. 6. The stabilized golf course bunker of claim 1, wherein said thickness of said barrier liner at said key way is in a range of ¾ to 1 inch. 7. The stabilized golf course bunker of claim 1, wherein said thickness of said barrier liner at said sides is in a range of ⅝ to ¾ inch. 8. The stabilized golf course bunker of claim 1, wherein said thickness of said barrier liner at said sides is in a range of ⅝ to ¾ inch. 9. The stabilized golf course bunker of claim 1, additionally comprising an opening at said floor in fluid communication with a drain pipe. 10. The stabilized golf course bunker of claim 9, wherein said drain pipe is disposed in gravel. 11. A method of stabilizing and lining a golf course bunker to be covered with sand comprising the steps of: a. preparing soil of the golf course by forming said soil and surrounding landscape into a desired configuration of a bunker having an opening, a top edge, a lip surrounding said opening, a floor, downwardly sloping sides and turf surrounding said opening, said downwardly sloping sides having a downward sloping grade;b. grading said top edge and said lip surrounding said opening to form an angled key way surrounding said opening, said angled key way having a grade extending outward and downward from said opening at an acute angle to form a hinge point between said angled key way and said downwardly sloping sides extending underneath a portion of said turf surrounding said opening;c. compacting said soil to produce a compacted soil surface;d. forming a barrier liner for said bunker by applying a portion of curable semi-solid barrier material on said compacted soil surface of said floor, by applying a portion of said curable semi-solid material on said downwardly sloping sides, up and over said hinge point, and on said angled key way, said portion of said curable semi-solid material on said downwardly sloping sides having a thickness, said portion of said curable semi-solid material on said angled key way extending under a portion of said turf surrounding said opening for a predetermined distance outside said hinge point, said portion of said semi-curable barrier material on said angled key way having a thickness which is greater than the thickness of said curable semi-solid material on said downwardly sloping sides; ande. allowing said curable semi-solid barrier material to cure to form a cured barrier liner, whereupon said cured barrier liner is configured to be covered with sand and which allows water to percolate therethrough to reduce water accumulation in said bunker and is sufficiently flexible to dampen or absorb impact when a golf ball hits said bunker. 12. The method of claim 11, wherein said barrier liner is cured for 24 hours. 13. The method of claim 11, wherein said curable semi-solid barrier material comprises a mixture of a dry binding agent, lightweight aggregate and water. 14. The method of claim 11, said predetermined distance is approximately 4 to 6 inches. 15. The method of claim 11, wherein said thickness of said barrier liner at said key way being in the range of ¾ to 1 inch. 16. The method of claim 11, wherein said thickness of said barrier liner at said sides being in the range of ⅝ to ¾ inch. 17. The method of claim 15, wherein said thickness of said barrier liner at said sides being in the range of ⅝ to ¾ inches. 18. The method of claim 11, wherein said barrier material is applied by hand. 19. The method of claim 11, wherein said barrier liner includes an outer surface and wherein said method additionally comprises fixedly securing a layer of finishing sand onto said outer surface of said barrier liner to form a finished outer surface for said barrier liner. 20. The method of claim 19, additionally comprising applying loose bunker sand over said thin layer of fixedly secured finishing sand.
