We are currently working on a project in Moraga, Ca that requires the installation of 16 resistance piers to underpin the entire right side of the house. The right side of the house will be lifted about 3-inches to correct the foundation settlement. After installing the first 6 piers at an average of 45 feet deep the job is well on its way. With the home having mature landscaping we have been careful to work around the vegetation to preserve the landscape to the best of our ability while not compromising the repair. This is a common question among homeowners when doing a preliminary design. In most cases the landscape will only suffer a minor disturbance.
