Located in the rolling hills and tree lined suburbs, Castro Valley is a place where the homeowner can enjoy a balance between natural beauty and the suburban comfort. However, behind that picturesque scenery is a problem that most East Bay dwellers are no strangers to, and that is slipping soil. The ground of the area is clay-laden which swells during wet seasons and contracts during dry seasons exerting consistent pressure on the foundations year in year out. The initial stages of settlement are often marked by small indications such as sloping floors, cracks in the drywall or by doors that are no longer able to close easily.
The repairs and stabilization of the foundation are to be done on the basis of the Castro Valley soil and terrain. We precise engineer the push pier systems, we correct settlement, restore structural balance and permanently prevent future movement. The home you are living in be it close to Lake Chabot, Redwood Road, or in the hillsides overlooking the town, our local team would be making sure that your foundation is as sound as the people it is helping.

The topography of Castro Valley is rolling which presents a special kind of foundation problem. Houses located on hilly slopes are very susceptible to differential settlement where a section of the foundation settles quicker than another segment as a result of the disparity in the pressure exerted on the soil. In the meantime, flatter areas tend to have their expansion and contraction of clay when it rains seasonally.
Our specialists conduct soil tests and laser measurements on the ground down to the smallest movements under your foundation. After mapping the problem areas, we develop a system of push pier which goes in deep to the stable strata, preventing further settlement and restoring the home to the original level.

Push pier systems depend on accurate hydraulic pressure to gain deep and firm foundational stability. This procedure enables the technicians to go through the weak strata of soil and fix the weight of the homes to some non-portable strata under the ground.
Hydraulic power provides the accuracy and strength of push piers to permanently stabilize foundations which is a requirement in Castro Valley with its mixture of hillside and valley-floor homes.
Deep rooted problems do not cure themselves. What started as a small crack or a crooked floor will soon develop into a fissure that becomes a structural issue at hand unless it is addressed. Doors and windows start sticking, walls start splitting apart and plumbing lines may crack as the building moves with time.
Postponing repairs will not only cost you more in the end but it will jeopardize the safety and value of your house as well. The installation of push piers at the earliest stage prevents the damage at its initial stage, averting any secondary problem and saving thousands of dollars of restoration expenses to the homeowners. It is always more prudent and less expensive to settle it immediately.
We were very happy with the results of our inspection with Ryan! He explained the settling in homes and what things we should look for, and was very professional, friendly, and efficient. Thanks!
Had a great experience working with Kyndell from Golden Bay Foundation Builders. I recently purchased the home and was looking for help with earthquake retrofitting options. He inspected my foundation carefully and determined that past bolting was likely adequate. He had suggestions about monitoring the foundation. He was very thoughtful and detailed in his approach, and worked to determine what was best for the home. In this case, that meant no need for additional work now. But if I need any additional assistance in the future, will be calling him again.
