Before PolyLEVEL injection. There is a 1" difference in height on the walkway.
After PolyLEVEL injection, the two sides of the sidewalk were once again level.
To the left of this crack there was a large void under the patio, causing it to sink on this side, which lead to the cracking.
The patio sections which sank were lifted to match the height of the remainder of the patio. The cracks were sealed and the patio no longer contains walking hazards.
There was damage surround the diving board section. The outside sections of the patio were sinking away from the pool, which caused cracking and eventually the diving board was pulling out of its footings.
The outside of the patio was lifted with the PolyLEVEL injection. Once the patio was level again, the broken sections and cracks near the diving board were repaired, making it stable once again.
The concrete patio surrounding this pool was gradually sinking around the perimeter. We used PolyLEVEL to fill the voids hidden underneath the slabs and raised the lower sections back to level. The cracks were then repaired and sealed.
