Martinez has managed to provide a combination of historic neighborhoods, hillside streets and waterfront properties which are defined by surrounding Carquinez Strait and rolling East Bay terrain. The preservation of the Victorian architecture of homes in downtown, the pavements that are silent around the Mountain View Park, and the land slope along the Alhambra Valley all encounter different patterns of soils that determine the long run stability of the foundation. Regardless of whether your house is close to the John Muir Historic Site, along the Alhambra Avenue, or situated on higher hillsides roads, even a minor change in the ground could have a bearing on the building over the years.
Seasonal changes in moisture, and erosion on the hillsides and aging fill products may cause movement under the homes in the neighborhoods such as the Vine Hill, Elderwood Glen and the areas leading to the Reliez Valley. Little cracks, bumpy floors or doors that have been moved due to soil expansion and contraction may take a long time to manifest themselves. Through careful inspection and focused strengthening we assist homeowners in Martinez to allow their foundations to be made strong again without further deterioration.

Rainfall, changes in ground water, and variations in temperature cause a drastic change in the soil conditions of Martinez throughout the year. Houses in hilly areas tend to have more movement, particularly houses located at the run-off channels or at the foot of the hills. The seasonal expansion of the soil may force its foundation, whereas in dry months, the soil may contract, which undermines the soil on which your house is built.
Our staff inspects these trends and works out the strategies to enhance the performance in the long run. We can intervene by strengthening weak areas and correcting a moisture imbalance and reduce the process of cracks, uneven floors, and continuing settlement. We insure the Martinez homes against the aggregate impact of annual soil variability with structural resilience.
The sloping houses in Martinez, particularly the ones close to the Alhambra Valley Road, Shell Avenue or the high-rise areas overlooking the strait demand customized solutions because of the pressure of the gravity and the soil movement of the hillside’s areas. These distinct challenges are met by designing reinforcement systems.
Houses cut into the hillsides commonly require additional stabilization to access layers of soil not affected by soil erosion or top weight.
We strengthen high-stress zones and redistribute the weight on solid ground, avoiding settling on the downslope side of the building.
Improved supports prevent the loss of foundation due to the run off, drainage, or natural ground movement.

Structural collapse is uncommon, but the circumstances leading up to it are frequently initiated by some of the small soil instabilities or unrecognized settlement. Our group recognizes the initial indicators of deterioration and applies reinforcement mechanisms to avoid structural stress.
Some of the indications that underpinning is required to secure your home are as follows:
We fix up cracks before they add to avoid the factors that might cause heavy structural failures: we keep the foundation firm and in place.
Our work is based on the concept of durability. We examine soil structures, drainage conditions and original construction methods to develop long term reinforcement plans. In the clay-filled soils of the area around Highway 4 to the hillside houses overlooking Pacheco Boulevard, each place is given a unique approach to its unique location.
We have long-term performance because of our comprehensive evaluations, robust materials, and supporting techniques that have worked in the mixed-terrain of Martinez. Our pride is in our ability to provide you with a solid assurance that your home is level, supported and structurally stable.
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.
