Foundation Repair Case Studies: Home Foundation Sinking Repair in Enfield Using Push Piers

Wednesday, August 22nd, 2012 by Marianne Koiva

Challenge

A single story residence in Enfield, CT was constructed in the mid-1960s and in 1998, the structure began to experience foundation settlement in the garage portion of the home.

Over a period of 12 years, the homeowners witnessed their garage foundation settle approximately 5 inches, causing significant damage to their home.

The settlement had become so severe that one of the home's garage doors was no longer operational.

Additionally, the garage slab had settled and became severely cracked.

The homeowners noticed cracks in drywall throughout portions of the home as well.

Realizing that it would be very difficult, if not impossible, to sell the home in this condition, the homeowners began researching their options to fix the problem.

Solution

After consulting with Connecticut Basement Systems, it was determined that the Foundation Supportworks™ Model 288 Push Pier System would be the optimal solution to not only permanently stabilize the foundation, but also give the best opportunity to lift the structure back to a level position. L-shaped foundation brackets were positioned below and against the home's footings and hydraulic cylinders were used to lift the foundation.

The piers were driven to an average depth of 70 feet to achieve ultimate load capacities of more than 43,000 pounds.

After the piers were driven to a load bearing strata, the structure was lifted approximately 5 inches to a level position, making the garage door operational once again. The entire project was completed in less than 3 days, and the homeowners were thrilled with the results.

The piers effectively stabilized the foundation and restored the home's value, allowing the homeowners to later sell the home for the full asking price.
