Engineered Foundation Solutions for Commercial & Industrial Clients
Our clients across NYC, Northern New Jersey, and the surrounding metro area rely on Premium Technical Services for advanced structural engineering and commercial foundation repair NYC projects that protect buildings from settlement, instability, and costly foundation issues. From retail centers to industrial facilities, we specialize in large-scale foundation repair and waterproofing solutions designed to address both immediate problems and prevent further damage.

- Helical pile installation programs that support sagging slabs, correct foundation problems, and prevent further damage.
- Structural repair for buildings showing hairline cracks, vertical cracks, and stair step cracks that can lead to instability over time.
- Crawl space repair and radon mitigation services for commercial and mixed-use buildings requiring environmental and structural protection.
FEATURED PROJECTS
Burlington Store 350 - NYC Metro Area
When employees noticed the concrete basement floor in a back-room storage area beginning to sag, engineers specified a helical pile program to stabilize the new slab. We supplied 57 helical piles over three overnight shifts to minimize disruption. The low headroom and vibration-free installation process made helical piles the ideal solution for this retail site, preventing foundation issues that could have led to further damage.
Georgetown Shopping Center - Northern NJ
Built over unstable landfill soil, the shopping center experienced decades of settlement. Over multiple phases spanning nearly a decade, we supplied more than 331 helical piles across different units. In phase 5, an additional 118 piles were supplied to stabilize a new concrete slab after ownership expanded the footprint. These repairs ensured long term stability and addressed persistent foundation problems caused by poor soil conditions.
