Back patio settlement
Challenge
The back patio had settled creating a tripping hazard and the home owners are older. They don't want to trip and get hurt.
When I did my investigation i found there was also a void on the back patio and walkway on the side of the house.
Solution
I recommended using PolyLevel on the whole back patio to lift and level the tripping hazard, fill the void and stabilize the whole area. Also to add NexusPro to the joints to seal them and protect from water intrusion.
