The Site
An external concrete driveway with several slabs joining to the garage.
The Issue
A middle concrete slab had dropped 40mm causing the slabs to be uneven. The drop in the foundation had become a trip hazard and was causing damage to the car. The driveway is built on reactive clays which over time had become affected by water ingress due to poor drainage. Reactive clays shrink and expand depending on moisture levels in the ground. This affects the overlaying foundations accordingly.
The objectives were to raise and return the slab to its design levels, to re-support it and to move the slab horizontally back to its original position.
The Resinject Solution
Resinject recommended remediation the driveway using their RSJ170 structural resin. RSJ170 is an engineered polyurethane resin that expands and solidifies when injected into the ground.
The resin strengthens the ground and re-levels the overlaying foundations
The required lift was achieved and the slab was supported and returned to the required position vertically and horizontally. The client was very pleased with the result and asked Resinject to remediate a subsidence issue on another of their properties.
Another reason to Resinject.
