Why Poly?
This job could have been repaired with cementitious grout (mudjacking) or polyurethane foam. The client in this case went with polyurethane, due to the smaller injection holes. If we went with mudjacking, then we would have needed to core the holes adding time and expense. If aesthetics weren’t a concern, then mudjacking would have been the cheapest option. Luckily, with CRC you have options and the know how.
