This common standard is based on engineering principles that rely on the largest 15% of the sand particles "bridging" with the smallest 15% of the gravel particles. The gravel must be placed evenly and raked smooth.

Sand Bunker Renovation 16 October 2025

Prior to placement of the pea gravel blanket or approved crushed limestone aggregate the Contractor will provide the Golf Course Architect with a record drawing (As-built) of the installed drainage. In addition to the record drawing Contractor will provide to Golf Course Architect digital photos, on CD Media, showing the complete drainage system prior to the gravel layer being installed and approved by Golf Course Architect or Owner.

11.3.5 ST410 POLYMER BINDER APPLICATION: ST410 POLYMER shall be sprayed by a certified and trained Better Billy Bunker installer. Using proper pressure spray equipment, a uniform layer of ST410 POLYMER shall be applied to the gravel in the bunker at a rate 1 gallon of ST410 POLYMER per 30- 35 square feet. The gravel must be dry (less than 15% as tested by the certified installer) at application time. The treated bunker shall be allowed to cure for approximately 24 hours prior to sand installation. NOTE: ST410 POLYMER will penetrate approximately ½ - 1” (12mm - 25mm) depth of the gravel. A sturdy pliable layer of glued gravel will be the result.

11.3.6 INSPECTION AND QUALITY CONTROL: After 12-24 hours, the initial ST410 POLYMER application will have cured. Contractor will walk and inspect every square foot (meter) of each bunker at the end of the curing process. Any areas not to have received the specified rate of polymer will be marked with turf paint and re-sprayed prior to calling for a final inspection by Golf Course Architect. Improper application or omitting the inspection process and follow up polymer application will leave areas weak and the pea gravel loose. It is installer’s responsibility to inspect and maintain the highest standards on when installing the Better Billy Bunker.
