Spent the morning pulling three of these out of the creek . Twenty footers old bridge timbers, these bad boys are what took out my water gaps in the last flood we had. Got another one going to have get one of the boys help on.
I don't know how much force was behind it, I know it hit so hard that it pulled one of the concreted 12 inch steel pipes over.
Never before has something hit the water gap that had enough force to move one of the pipes.
