The combination of waterfront communities, hillsides streets, and historic residential neighborhoods in Benicia, provides conditions of foundation that change according to the unique climate of the city. The houses around Southampton Road, Rose Drive and the hilly terrain above Carquinez Strait are built on soil which swells with moisture of winter seasons and shrinks in dry and windy summer seasons. These are the evolving conditions that directly affect the behavior of slab foundations resulting in cracking, movement or sinking with time.
Homeowners can initially observe small problems the presence of fine cracks that develop on the inside flooring, doors that do not close properly, or slight depressions that develop in one part of a room. These symptoms may take place in old house of Benicia, especially the houses along East Second Street and Military East, due to the decades of soil movement under the slab. Our team will locate the circumstances that are unique to your house and develop slab repair solutions that will help in response to the divergent soil and moisture formations in the state of Benicia.

Our slab repair programs are aimed at fixing the underlying cause of the movement, and not fixing cracks that are visible. The soil in Benicia is highly fluctuating even in small areas, and therefore, it is vital to be evaluated accurately. We examine the load distribution of the house, patterns of drainage, and soil mass so that we can find out which area of the slab is losing its support.
After identifying the areas of the problem we apply sophisticated lifting and reinforcing techniques to re-align the slab and ensure that it is stable again. This will be made strong in the long term as a result of minimizing repetitive settlement, seasonal settlement, or movement of soil due to moisture. The reason why the homeowners prefer us is that we perform a thorough diagnostics and the repair process which is of the industry leading techniques dedicated to the various terrain of Benicia.
Slab failure does not occur immediately, but develops over a period of time as the soil changes. In this section, the density of soil, the absorption of moisture and the natural aging of construction materials are expounded on to form small variations which eventually form cracks or sinkages. Knowing these forces enables us to select the right repair strategy in order to be stable in the long run.
Soils that are heavy with clay swell during winter rains and press upwards on portions of the slab.
During the drying process, the soil contracts and shrinkage occurs and leaves areas with no support.
Some houses that were constructed many decades ago might have unequal soil density and as a result, one part of the slab sinks quicker than the other.

One of the major causes of the movement of slabs foundation in Benicia are soil erosions. The changing levels of moisture, hill slopes and runoff of water cause uneven support under the slab.
Detection of the erosion-related slab issues can include:
The slab loses its stability and starts to settle when the soil either washes, becomes weak or compacted unevenly.
A good example of indicators that the foundation is weakening is sunken slab floors. Houses located in hillside areas or those properties that are influenced by the water runoff tend to sink on one side of the slab. We do precision lifting as a method of lifting areas which are affected, fill soil voids, and level flooring around the entire house.
We can work to prevent any additional sinking or cracking of the surrounding soil that is weak in order to help homeowners. Our techniques make sure that after the slab is removed and it is upheld it will stand until the next seasonal soil variations.
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.
