Car jack support require a strong and stable foundation to prevent cracking, sinking, and shifting over time. Screw piles provide superior load-bearing capacity by anchoring the slab below the frost line, eliminating the risk of frost heave and soil movement. Unlike traditional concrete footings, which can settle unevenly, screw piles ensure consistent support and prevent structural damage. They also allow for faster, year-round installation with minimal excavation, reducing labor and material costs. By using screw piles, garage floor slabs remain level, durable, and maintenance-free for years to come.
