Why use the Better Billy Bunker Method™?
-
No Liner Required
Installation of The Better Billy Bunker Method™ uses a polymer binder to stabilize the drainage stone beneath the bunker sand. No liner means clubs and rakes won’t get snagged and the bunker’s aesthetic appearance will remain intact for a longer period of time.
-
Improved Drainage
The Better Billy Bunker Method™ polymer binder allows water to drain through the stone at an incredibly high rate.
-
Low Maintenance
The Better Billy Bunker Method™ increases profitability by reducing golf course maintenance labor costs. Grounds crews won’t need to spend time fixing exposed liners or pumping puddles from bunkers after rainstorms.

Step 1: Remove Sand & Inspect Drainage
Excavate 6" profile to allow for the 2" gravel layer and 4" of sand. If plans call for an exposed thatch edge, calculate this depth in for further excavation. The floor should be smooth and compacted. Drain tile can be reused if it is still functional.
