- About Us
Atlas Piers (or more technically Atlas Resistance® Piers) utilize the weight of the structure as its reaction system to drive or push the pipe pier sections into the soil. CHANCE® Civil Construction has developed a lasting solution for many distressed foundation problems through its patented and tested Atlas Resistance® Pier System. The pier is an assembly of structural steel components that include a pier head assembly attached to the foundation or slab, which is then mounted on a steel pier that is installed to bedrock or firm bearing stratum. The unique friction reduction collar on the lead section of the pier reduces skin friction on the pier pipe during installation. The pier does not rely on skin friction for support. The Atlas Resistance® Pier has been successfully driven to depths of 200 feet to ensure proper and verified support.
Atlas Resistance® Piers are a manufactured, two-stage product designed specifically to produce structural support strength. First, the pier pipe is driven to a firm bearing stratum; then the lift equipment is typically combined with a manifold system to lift the structure. This procedure provides measured support strength. Piers are spaced at adequate centers where each pier is driven to a suitable stratum and then tested to a force greater than required to lift the structure. This procedure effectively load tests each pier prior to lift and provides a measured Factor of Safety (FS) on each pier at lift.
