Water enters sand then stops at clay.
Water must move horizontally
through sand to enter drain.
Once the sand is saturated with water any sand on steep sloped faces begins to move.
The sand has slid down the face with soil from the bunker slopes.
The sand is now contaminated with clay and will begin to perform poorly.
A layer of silt covers the top of the bunker and prevents water movement vertically.
The drainage slows and the sand goes from white to the color of the soil.
Sand must be shovel back up for play to resume.
Using a 2” layer of gravel, glued to stay in place, the water now enters the rock layer and moves horizontally quickly to the drain lines preventing a slide, contamination and the movement of the sand
