The conditions of the foundations of San Leandro differ greatly between hilly side communities, beach neighborhoods, and old residential areas. Houses located in Washington Manor, Halcyon and Estudillo Estates tend to be built on soils that are clay-based and thus expand during winter storms and shrink when the soil dries out, putting strain on slab foundations. Homes around Marina Boulevard, Oyster Bay and the industrial shore are more likely to be located near to fill or sandy soils which tend to settle unevenly as time goes through.
In some areas of San Leandro, especially Broadmoor, Assumption Parish, and construction patterns of the areas around the border to Oakland, the compaction of soil and the aging construction may cause gradual but steady slab motion. Our team analyses these conditions keenly to come up with repairs depending on the interaction of the soil with the structure.

The first step in prevention is to know the soil on which your home is on. Dynamics in the moisture support on the slab in San Leandro result in support fluctuations that will have a cumulative impact. The houses along the drainage pathways or lowlands might experience recurring soil saturation, which increases settlement.
Homeowners can mitigate the risks of large structural shifts by observing the drainage patterns, maintaining a constant level of soil moisture, and fixing cracks in their initial stages. In the cases when the warning signs are observed early, the extensive destruction of foundations may be avoided through timely reinforcements.
The combination of soil types, topography and water content in San Leandro demands slab repairs which cannot be generic. Our solution is based on precision, strength over time and determining the precise soil response on the slab. Each repair is designed to fit the environment of the house and avoid future problems.
We determine the factors of slab movement such as moisture, compaction and soil type.
Our methods are used to strengthen weak areas and even up foundation support.
In preventing future sinking or cracking, it is better to correct the cause of the problem.

Shifting usually starts overtly, although the indicators are more evident as the soil movement continues.
Key indicators include:
We determine the source of movement, be it due to a change of moisture, soil shrinkage or a settlement that has taken place over a long period and we advise solutions that will ensure support is regained.
Weak spots on a slab foundation are usually brought about by the imbalance of moisture or slow compaction under the house. Due to the heavy clay and fill soils of San Leandro, the movement may be quick during weather changes between seasons.
We strengthen weak areas, stabilize loading slab and harden level support of the entire house. Our procedure will guarantee that every repair is aimed at correcting the underlying behavior of the soil to ensure that no future problems will occur, and ensure the structural stability of the building.
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.
