Washouts are sometimes hard to spot. A contractor happened to observe water bubbling up at a joint near the water line. It took under a day and around 20 yards to fill this void.
We can’t fix everything
We can’t fix everything, sometimes tear out and replacement is your best/only option. However, we give free estimates and are more than willing to look at your situation be it a walk, drive, patio, or pool deck. This one is better left to a concrete contractor.
