Photo Album: Deflection of Fieldstone Foundation Wall, Manchester, NH

A homeowner in Manchester, New Hampshire, purchased their home in 2021 and had plans to remodel the house built in the 1930s. Before they could remodel the home, the homeowners wanted to address the sagging floors and their fieldstone foundation wall being pushed outward. The homeowner had noticed the sagging floors and the fieldstone foundation bulging out when they first purchased the home in 2021. They decided to call EFS for a free inspection, and our design specialist recommended installing SmartJacks, Auxiliary Walls, and a slab pour in the basement.  Our production team began by installing the SmartJacks to add support to the floors on the main level of the home. The team used a combination of engineered fill and big plate footings to create a solid base to support the main floors of the home. Next, the team attached the SmartJacks to the main beam and used the adjustable top of the SJ to lift and level the main floor. After the SmartJacks were installed the team called a concrete truck to pour a new slab. Once the slab cured the team then started to set up the Auxiliary Walls against the fieldstone foundation wall. The team used PowerBraces, rebar, wall forms, and concrete to create the Auxiliary Wall. After the concrete was poured against the fieldstone foundation and wall forms the team had to wait for the concrete to cure before they could remove the forms. Once the concrete was cured the team removed the forms and remove any imperfections in the auxiliary wall.
