About H.L. Chapman

Welcome to one of the largest custom trenching and mass rock excavating companies in the world.

We do not lay the pipe or build the roads. Because of this, we have devoted all of our efforts since 1974 into building a service to trench and remove rock faster than anyone else without the use of explosives. This in return has made us the leader in trenching and mass rock excavation in the world.
