Today brought 1.5" of rain in 3 hours and it was a nice test for the new bunkers we just built and lined with Matrix Mix. While other parts of the golf course, including bunkers not yet renovated, were extremely wet and formed puddles or streams, the new bunkers stayed intact and did not hold any water. This new bunker construction method being used allows for improved playability following heavy rain as well as less maintenance needed to repair them before play. As can be seen, it also reduces risk of contamination from soil or silt running into the bunker from the edges.
