It wont need to be blown up ever again no leaking or puncturing ever either, will also stand on its own better if you weigh down the bottom of the foam with some sand beforehand. Harder to store though (probably just leave it up at that point) and it is heavy and harder to move around with sand in the bottom. Advantage is no more stakes or really caring that the wind is blowing hard on the bunkers or that people are using metal cleats to pop em. Small bunkers wont take to much to fill them fully with spray foam a carwash or other large bunker would be probably to pricey though unless you can source a cheap *** source of spray foam.
