After the removal of a wooden deck, dangerous voids under the brick pavers were revealed in a luxury apartment pool deck, threatening its integrity and safety. The property owner contacted [Helicon](https://heliconusa.com/), a trusted foundation repair company.

## Initial Assessment

Subsurface investigation confirmed extensive voiding with no practical access for excavation during occupancy. Demolition/replacement would take weeks, cost tens of thousands, and the pool would need to be closed during peak season.

## Proposed Solution

The contractor selected [AP Lift 440](https://alchatek.com/geotech/polyurethane-concrete-leveling-products/slab-foundation-lifting-ap-lift-440/) for its hydro‑insensitivity, ~15‑minute cure, and ~80 psi compressive strength. This material was ideal for increasing the soil's bearing capacity and restoring the pool to its correct state.

## Procedures

1. Map the void locations using ground-penetrating radar and probing.
2. Establish an injection grid targeting the largest voids first.
3. Drill strategic injection ports through pavers to void spaces.
4. Inject AP Lift 440 to refusal using calibrated pressure monitoring.
5. Allow 15-minute cure
6. Seal injection ports and restore surface aesthetics.

## Results

- Structural integrity fully restored with 1,200 lbs of AP Lift 440, filling all voids.
- Zero operational downtime; pool deck remained accessible throughout repair.
- Approximately 70-90% cost savings compared to demolition/replacement alternatives.
