Patent ID: 8529159

Claim:
A method for constructing and renovating golf course bunkers to improve infiltration of water through a drainage system and to reduce contamination and erosion of the bunker sand comprises: testing the selected sand to be used by piling the sand on a level surface and measuring the slope angle of the sand pile; building the floor of the bunker to a grade that is less than or equal to 80% of the measured slope angle of the sand pile; installing a drainage system of perforated drain pipe with a locator wire; placing a layer of pea gravel over the entire floor of the bunker; applying a pre-polymer using a spray-gun, to 90-95% of the pea gravel at a discharge rate of 0.03-0.04 gallons per square foot; and installing a nonwoven geotextile fabric with an approximate mesh opening of #20 US Sieve, over the area that is not treated with the pre-polymer.
