Topography in Danville is expansive open valley, gently rolling hills and creek influenced parcels which form varied behavior of soils. The residents in the Blackhawk, Diablo Road, and Crow Canyon neighborhoods usually have their homes resting on clay soils that swell during rainfall and shrink during the sunny months imposing constant pressure on the foundations and exterior walls. Soils in the area of Sycamore Valley, West Danville and El Pintado Road might become soft, experience ground run-offs, or natural compaction due to the erosion of top layers of soil over decades.
These natural forces may lead to the settlement, movement or lack of ability of these soils to sustain weight balancing. Tilting concrete pads, irregular surfaces on the driveways, or soil that is moving away on the retaining walls are early signs that are normally an indicator of underlying instability. Our company offers soil stabilization solutions that aim to reinforce ground performance in the various landscapes of Danville to enable the owners of the houses to safeguard the home and the landscaping.

The climate of Danville presents soil to foreseeable patterns of wet winters and hot and dry summers. These movements lead to the expansion and shrinkage of clay rich soil with moisture and increased temperature respectively which imposes upwards and downwards pressure on foundations.
Our staff determines the effects of weather patterns on your property and applies methods of stabilization to minimize the effects of shrink-swell cycles. We eliminate shifting, structural distortion and long-term settlement problems by enhancing the resilience of the soil.
Driveways, access roads and also the private lanes in Danville often form cracks, dips or ruts as the soil slips under it. Prior to resurfacing or reconstruction, it is important to stabilize the ground first so that the performance can last longer.
The deeper layers under the driveway or roadway are reinforced to ensure that they do not sink and wear unevenly.
The soil stability is enhanced, and the movement of water across and through the surface is enhanced, which prevents erosion.
Stabilized soil has a strong, stable foundation that does not submit to seasonal soil movement.

Soft-story buildings are based on the guessable soil support. Structural stability can be destroyed when the ground starts getting loose or moving in relation to the weather periods. The combination of clay-heavy hilly side soil and deteriorating valley fill endears soft-story buildings in Danville especially.
Owners of properties frequently call us having noticed:
We interpret ground stabilization with specific retrofitting addition to upgrade to the stronger support system at the lower level.
There are areas in Danville which have pooling/or heavy run-offs during seasonal storms. This may make soil soft, enhance soil erosion, and reduce ground support at the foundation and retaining walls.
We determine the interaction of water with the soil surrounding your house and implement stabilization measures which enhance the drainage system, reinforce weak areas and minimize the effect of moisture in the long term. Your soil will be stable even in the wet weather with the appropriate reinforcement.
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.
