The development of Moraga is characterized by peaceful valleys, neighborhoods on the hillsides and creek-side that are all influenced by highly responsive soil to seasonal moisture. The houses around Rheem Boulevard, and the surroundings around the Moraga Road are usually constructed on soils that contain a lot of clay, which swell during rainy seasons and contract during heat periods in summer. Meanwhile, the properties nearer to Rancho Laguna Park, St. Mary College and lower and more flatter pockets in the nearby areas of the Moraga Commons might be built on soils that have been affected by water run off, water movement, or long term compaction.
Symptoms such as a lumpy exterior concrete, cracks extending around patios, or soil sliding off of the side walls usually give warning that soil under your house is starting to move. Our company focuses on soil stabilization systems tailored to the terrain of the area that is susceptible to moisture in Moraga and your property should be provided with the ability to withstand over time.

The soil in Moraga acts differently based on the moisture content, slope pressure and composition on which it is placed. Clay swells in case of rain and shrink in dry conditions and moves gradually in the downhill direction in the neighborhoods in the hills. This can also be because of soil being softened by groundwater of storms or the surrounding creeks that raise the risks of settlement.
Our team looks at the effect of moisture, types of soil and slope conditions on your property. When we know such factors, we apply the stabilizing methods that enhance soil structure, reduce the number of shrink-swell cycles, and provide the uniform support of your foundation and other surrounding enhancements.
Soil issues usually start with subtle nuances and develop rapidly with the alteration of the weather conditions. The ability to know when to request assistance makes sure that your property is safe and stable.
When the driveways, pavers, or patios start to shift, or a depression forms in a driveway, it can be an indication that the soil below is getting weaker or moving.
Expanding cracks in stucco, retaining walls or ground-level framing normally represent more profound motion of soil that will call to mind urgent intervention.
The perimeter may be unstable due to the runoff channels, washed-out soil or pooling water that may not support its foundation.

The multi-unit buildings and the old houses in Moraga contain numerous ground-level openings, which are susceptible to the soil movements, and thus, soft-story buildings are more susceptible to soil movements. A shift in the soil below the bottom level may result in weak structural support points and loss of capability of the structure to resist the lateral forces.
Owners of properties summon us when they notice:
We mix reinforcement of soil with structural improvements to discourage continuing soil motions and seasonal water content variations on soft-story buildings.
Moraga property, when stabilized, offers decades long protection to the soil. The reinforced ground layers have the benefit of withstanding the changes in moisture seasonally, lessening chances of settling, cracks in the ground, and stressing the foundations. The built houses on the sloped areas will be less exposed to the downhill erosion of the soil and the houses constructed in the low-lying areas will have a safe-havens against the erosion and the weakening caused by moisture.
The foundations stand on solid ground, and the landscaping will remain level with the foundations as well as the building on top will move a lot less. This conserves property value, and it saves the maintenance cost in the long run.
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.
