What about ground that has been backfilled?

If your ground has been backlled with chunks of concrete, eld stone or any other materials that can create air pockets under the ground, the WamBam system is not the way to go.

Our system is ideally designed for virgin soil like clay. Underground pockets of air created by incongruous materials will not provide enough structural integrity for our pipe anchors. If you ground has been backlled with clean ll, but has not been mechanically compacted or given enough time to settle, this could pose problems as well. In these cases we would recommend you dig traditional concrete footings.
