The diverse soil types of the city (San Jose) such as the clay-soil-based neighborhoods of Almaden Valley and Evergreen to the sandy-soil-based groups of Alviso and the older districts by the area of Japantown, Willow Glen and Rose Garden present diverse foundation challenges. The swellings and contractions of the ground are affected by seasonal moisture variations and that some regions are settling as a result of decades old fill or natural soil compression. Slab foundations in the entire city do not respond in the same way basing on the location of the property, the age and terrain of the property.
Homes bordering Coyote Valley, Cambrian, Berryessa, and Silver Creek can experience some of the insidious initial signs like cracks in the interior, tiles stamping or even slight slopes forming in the flooring. These signs suggest that soil activity under the slab would start to vary. San Jose has a combination of hillsides as well as valley floors and urban infill areas; therefore, foundation problems should be evaluated accurately.

This prevention is very necessary in areas such as San Jose which has many different soil types that may respond differently to moisture. Homeowners can reduce the movements of slabs by enhancing the drainage, by ensuring the soil is kept at the same moisture level and fixing cracks developed on the surface of the slab before they get serious. In hilly areas, water run-offs and movement can be managed to reduce soil movement.
Early warning signs can be identified and through professional evaluation, the need to be reinforced or not is determined. The early resolution of problems eliminates structural stress in the long term and makes subsequent repair less expensive.
Most of the times the soil under the slab saturates consequently making the foundation either lift or sink depending on the distribution of the moisture. The drainage issues are discovered in our team and reinforced to stabilize soil and eliminate continuous deformation of slabs.
We make sure water runoff and irrigation do not drown soil under the slab.
We reinforce areas that have been weakened to ensure that they do not move or crack any further.
Adequate stability would ensure that the slab would not move in the future due to uneven moisture distribution.

Slab foundations are found to move when the soil under them moves irregularly. This occurs in San Jose because of a number of reasonable things.
The result of these conditions is the appearance of uneven support under the slab, which results in cracks, sinking, or misalignment of the inside.
The soil movement contributes significantly to the cracking and movements of slabs. Soils with a lot of clay swell when they are wet whereas sandy soils may also move through solid saturation or erosion. Considering the various terrain in San Jose, the slab can crack due to the fact that one side is on clay soil whereas the other is on a loose soil.
We examine the composition of soil, state of moisture and structural load to decide where repairs are required. Using the stabilization of the soil and the stiffening of the slab, we prevent the flow and make the cracks and restore the structure of the home.
Steady, well-organized repair service focused on structural safety and durability.
After noticing doors sticking and cracks in our drywall here in Warm Springs, we called for a foundation inspection. The team was incredibly thorough, using laser levels to measure settling and explaining everything in plain terms.
Nisan was very helpful on guiding me via the permit process for earthquake retrofit. Work was executed quickly. Thanks
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.
We needed crawl space repairs due to pests and moisture damage. They sealed it up, reinforced the beams, and added vapor barriersnow it’s dry and structurally sound. Excellent service from start to finish!
