The resistance pier system is 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 combined with a manifold system to lift the structure.
The Atlas Resistance® Pier System manufactured by A.B. CHANCE provides measured support strength. Atlas Resistance® 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 on each pier at time of lift.
