AP Lift 475, a high-strength polymer, was crucial for this stabilization project. Its placement near the condo's footing made this material the perfect choice. AP Lift 475 provides exceptional load-bearing capacity, which is ideal for supporting large structures. The polymer's robust properties ensure long-term support for the repaired power lines. Moreover, its strength offers a reliable foundation for the electrical system, preventing future settlement issues.
The repair process began with careful excavation. In order to access the crushed duct banks 12 feet below grade, the workers removed soil and concrete next to the building. Next, the geotech team installed 15-foot injection rods into the soil below the duct banks for deep soil stabilization, a technique also known as Deep Lock®. The team methodically created a grid pattern with 12 injection points, each spaced about 3 feet apart. This systematic approach ensures thorough soil treatment throughout the affected area. The specialists achieved comprehensive stabilization by injecting the polymer at multiple points, addressing all potential weak spots in the soil structure.
The entire project was completed in less than two days. Once the soil was stabilized, electricians safely reinstalled power lines through new duct banks into the building. The duct banks were then covered with well-compacted backfill. The condo ownership could finally stop the costly generator payments. Most importantly, the repair provided a permanent solution to prevent future power line issues. This quick, effective intervention minimized disruption for residents while ensuring long-term stability for the building's power supply.
