Push Piers installed at First Baptist Church in Clinton, MO to help stabilize structure

Challenge

The First Baptist Church has been around in Clinton, Missouri since 1866 but for last couple of years, members have noticed continual movement of the South foundation wall which had caused several seams to open and cracks to develop on the interior in their large, one-story new brick structure. The owner of the church wanted to stabilize the foundation, with no lift, due to the fact that they can repair the cosmetic damage that was done and eventually repair the building. Foundation Recovery Systems performed an interior inspection and found that the 98-foot South wall had a maximum vertical deflection of about one-inch, most notably on the Eastern half of the wall. Additionally, the South wall was also tipping outward around a half inch which left a gap between the slab floor and the outer wall.

Solution

To stabilize the foundation wall, FRS installed a total of nineteen 3-inch Push Piers with a Standard Bracket; fifteen were installed across the 98-foot front wall that wrapped around both corners with two piers each. But after first arriving, FRS had to remove some landscaping items before work could be started. Nineteen Push Piers were installed by first removing soil from the area where the piers needed to be driven. A heavy-duty steel bracket was then installed below and against the foundation’s footing. The steel pier sections were hydraulically driven through the bracket to bedrock. The weight of the structure was then transferred through the piers to competent soil and the building was stabilized. Once the stabilization took place, the soil was backfilled and the building is now permanently stabilized in its new position, allowing other work to be completed. With the stabilization being completed, the next project was to level the office and bathroom areas because they had sunken. This was completed by injecting PolyRenewal into 5/8-inch holes into the slab and allowing the PolyRenewal to expand underneath. Once the lift was completed, the holes were concreted. Both jobs were completed in just two days!
