Golf bunker liner

Abstract

The present invention is a product, and a method to create a solid interface (or barrier) between soil and the sand of a golf sand bunker.

What is claimed is: 
     
         1 . A method of stabilizing and lining a golf course bunker comprising the steps of:
 a. preparing soil by forming the soil and surrounding landscape into a desired configuration of the bunker having a liner, a top edge, a lip, an opening, a floor, sides and turf surrounding the bunker opening;   b. forming a hinge point around the top edge of the bunker such that there is approximately a 45 degree angle formed by grading the bunker top edge and the turf surrounding the bunker opening;   c. compacting the soil and its surface;   d. applying a liquid adhesive polymer to the surface of the soil to assist in stabilizing the soil;   e. allowing the soil to stabilize;   f. applying a barrier material around the bunker floor and sides and continued on up over the top of the bunker while maintaining an approximately 45 degree angle and for a distance past the bunker;   g. allowing the barrier to harden;   h. applying another layer of liquid adhesive; and optionally applying a layer of clean, dry bunker sand to the bunker floor and sides; and   i. curing of the bunker liner.   
     
     
         2 . The method of  claim 1  wherein the curing of step (g) is for 24 hours. 
     
     
         3 . The method of  claim 1  wherein the barrier material comprises a mixture of a liquid binder including an adhesive and a plastic cement, fiberglass fibers, lightweight aggregate, water and optionally, a hardener. 
     
     
         4 . The method of  claim 3  wherein the fiberglass fibers are fibrillated polypropylene microfibers. 
     
     
         5 . The method of  claim 1 , step (c) wherein the liquid adhesive is sprayed on. 
     
     
         6 . The method of  claim 1 , step (d) wherein the barrier material is applied by hand. 
     
     
         7 . A stabilized golf course bunker comprising soil and surrounding landscape in a desired configuration of the bunker having a liner, an interior surface, a top edge, a lip, an opening, a floor, sides and turf surrounding the bunker opening, a hinge point around the top edge of the bunker such that there is approximately a 45 degree angle formed by grading the bunker top edge and the turf surrounding the bunker opening, compacted soil on the interior surface, stabilized soil prepared using a liquid adhesive polymer on the surface of the soil, a barrier material applied around the bunker floor and sides and continued on up over the top of the bunker with an approximately 45 degree angle and for a distance past the bunker and hardened; a second layer of liquid adhesive; and optionally, a layer of clean, dry bunker sand to the bunker floor and sides;
 and curing and the bunker liner.   
     
     
         8 . The bunker of  claim 7  wherein the barrier material comprises a mixture of a liquid binder including an adhesive and a plastic cement, fiberglass fibers, lightweight aggregate, water and optionally, a hardener. 
     
     
         9 . The method of  claim 7  wherein the fiberglass fibers are fibrillated polypropylene microfibers.
