"Plumbing leaks' under my slab are ruining my house!"

An Austin, Texas, homeowner was noticeably upset when talking to our Atlas Dealer. It seems that the old cast-iron sewer line under the home had deteriorated. A plumbing contractor confirmed that multiple leads were evident.

The homeowner went on to say that large cracks started appearing in the interior of the home, doors would not close, light was visible between the outside door and the frame at the rear of the house, and cracks had appeared in the concrete slab. Could the home be saved?

Home Exterior

Our Atlas Dealer installed 25 ATLAS RESISTANCE PIERS around the perimeter of the foundation. Not only did the ATLAS RESISTANCE PIERS provide stabilization, the piers were used to raise the foundation as much as 3-1/4 inches to restore the house to as close to the original evaluation as the construction would allow.

THE SOLUTION: ATLAS RESISTANCE PIERS!
STABILIZED AND RESTORED THE HOUSE!

Atlas Resistance Piers
Lift Force vs. Drive Force & Ultimate
Graph

The chart above shows the ultimate pier capacity is over four times the average pier load. The average driving force is over 60 percent above the average pier load.

This 35-year-old-house is constructed upon a steel-reinforced concrete slab with a turned down footing at the perimeter. The exterior has masonry on the front and wood siding on all other sides.

ATLAS RESISTANCE PIERS were installed around the perimeter on approximately eight-foot centers in order to stabilize the structure. The piers were driven to a bearing stratum of reported weathered limestone at a depth of approximately eight feet. The restoration process removed up to 3-1/4 inches of settlement!
