Slowly as it rains, the sand finds its way into the substrate. Large substrate pebbles, rocks and dirt are forced up through the sand to the surface. This process also occurs during the freeze/thaw cycles in northern climates.
With SANDTRAPPER installed, the effects of time, water and freezing are eliminated. The sand stays where you want it to. The substrate pebbles, rocks and dirt stay separated from your beautiful course feature.

The result after many months of nature's forces is a sand trap that requires no rebuilding. The sand stays in place, your sand trap stay beautiful and your labor budget is spared.
