The most recent addition to the Sandtrapper product line is Sandtrapper GEO. Where the prevailing concern is contamination, it provides total control at an extremely affordable cost. Since not all course designs have steep bunker faces, Sandtrapper GEO works best when you're building or maintaining bunkers with a relatively flat, broad style with grass faces or no face at all.
Designed for those "contamination only" environments, Sandtrapper GEO is a tight matrix, designed to allow water percolation through the barrier, yet holds the rocks, soil, debris and subsurface particles below it.
