When the concrete truck “spins out” his barrel into your foundation wall, no matter how good you vibrate it, you sometimes get what contractors call...honeycomb. It’s ugly, unsound structurally and engineers and inspectors hate it. This is the perfect job for a fast setting, hand placed structural patch such as Quickset, V/O Patch CI or R3. Just mix, force it into the voids with gloved hands or a small trowel, let it take its initial set and shave off any excess. With 5,500 to 7,000 psi ultimate strength the wall is as good as if the honeycomb never happened.
