THE PROBLEM: This structure was built on a lot with a slope. After the lot was leveled, the fill material under the structure began to consolidate. Soon the structure began to show signs of distress, there was compaction of the fill. Cracks and masonry misalignments appeared in the exterior walls.

Soil borings revealed that suitable bearing strata occurred at 40 to 45 feet. The engineers had another problem. There was a sewer line located 30 feet directly below the footing. Drilling concrete piers would be impossible and relocating the sewer line uneconomical.

THE SOLUTION! ATLAS RESISTANCE PIERS

PROJECT SUMMARY Installed by: Atlas Piers of Atlanta Alpharetta, Georgia Resistance Piers: 57 Part Number: AP2S-3500 Pier Depth: 38 to 49 feet Ave. Drive Force: 60,000 pounds Lift Force: 20,000 pounds Ultimate Capacity: 85,000 pounds Factor of Safety: 2.90 to 3.11:1 (working) 4.25:1 (ultimate)

The selection of ATLAS RESISTANCE PIERS was the key to the success of this project. Not only did ATLAS RESISTANCE PIERS provide superior structural support and allowed for quick completion; it was the most cost effective solution because the sewer line under the structure was not disturbed during the installation of the piers! Each ATLAS RESISTANCE PIER was driven to a force greater than required to support the structure. The graph above shows the average factor of safety on this project to be 3:1.
