Abstract
A method for treating golf course sand traps to reduce contamination of the sand and to reduce erosion. The bottom of the trap, which is substantially devoid of playing sand is roughened. An initial amount of hydrophobic liquid polyurethane is applied to the roughened soil on the bottom of the trap. The trap is raked and an additional amount of hydrophobic liquid polyurethane is applied to the bottom of the trap. A thin layer of sand is applied to the bottom of the trap and a further additional amount of hydrophobic liquid polyurethane is applied to the sand and the sand is raked. The thin layer of sand is sprayed with water and the trap is permitted to cure for approximately 24 hours. A sufficient amount of playing sand is then added to the trap so the trap is playable.
