Foundation Repair Project in Phoenix, Arizona: A Remarkable Transformation (Final Part)

Introduction

In the heart of Arizona, specifically in Phoenix, a challenging foundation repair project was undertaken, which showcased the expertise of residential foundation repair contractors near the area. This project involved the remediation of a commercial warehouse located on top of a solid landfill, and it's a testament to the capabilities of foundation specialists in Phoenix. The foundation of the building had experienced significant issues, including foundation cracks and a sinking foundation, making it essential to address the problem promptly.

Challenges Faced

The foundation repair contractors faced a multitude of challenges during this extensive project. The initial hurdle was dealing with the unknown composition of the soil, which included concrete, steel, dirt, voids, and more. This diversity in the soil made the foundation work near Phoenix even more complex. Additionally, the size and weight of the warehouse and the magnitude of the required lift, which amounted to over 15 inches, posed significant challenges.

Environmental Factors

In 2018, during the fall and winter seasons, Phoenix experienced unusually heavy rains. These rains had a substantial impact on the building, causing it to move significantly before the stabilization work could be completed. The exact reasons for this movement were debated among experts. Some pointed to the proximity of the river, which was within 300 yards of the site. Others believed that open excavations, despite water diversion efforts, contributed to the issue. Some even suspected unknown subsurface water movements, but a definitive cause remains elusive.

Foundation Repair Details

The foundation repair project involved a comprehensive plan, which included the installation of 303 hydraulic piers at 30,000 pounds working loads, providing a total capacity of 9 million pounds. These piers were drilled to an average depth of 70 feet and connected by welding to ensure their strength and continuity. Each pile was pushed to refusal after installation, further enhancing the stability of the structure.

An impressive 5 million pounds of grout were used in this project. This grout was injected into 438 compaction grout holes located in various parts of the building, including interior slabs, columns, and parking lots. The interior columns were lifted by up to 6 inches through compaction grouting under their footings. This process required pre-drilling with a down-in-the-hole hammer to depths of 60 feet. The grout was delivered at pressures of up to 1200 PSI, resulting in over 4,000 yards of grout being injected, totaling 15 million pounds.

The east site wall was reinforced with 98 micro piles, each reaching a depth of approximately 50-60 feet, providing nearly 3 million pounds of capacity for approximately 300 linear feet of 8-foot-tall site wall. This comprehensive approach ensured the stability and integrity of the entire structure.

Conclusion

This extensive foundation repair project in Phoenix, Arizona, showcases the capabilities of residential foundation repair contractors and foundation specialists in addressing even the most complex foundation issues. Despite the challenges posed by unknown soil composition and adverse weather conditions, the project was completed successfully, resulting in a remarkable transformation of the commercial warehouse. The foundation repair near you in Arizona has not only saved the structure but also allowed it to be occupied and used fully for the first time in its history. This project serves as a testament to the expertise and dedication of foundation contractors in Arizona.
