The topography of Contra Costa County, which is dominated by steep hills on the south and east sides, extends to the flat fast growing development areas of Concord, Antioch and Pittsburg on the west side. These diverse terrains are placed in soil profiles that are different in responding to moisture, weight and season variations. Residential areas on foothills of Mount Diablo, business developments along Treat Boulevard, and residential areas along water fronts at Bay Point are all under conditions where soil stability has a direct impact on structural performance in the long run.
Clues in the form of moving landscape wall, irregular outward flattening of pavements, expansion of cracks on the ground or soil eroding at the foundations can be early indications of underlying instability under a property. Having hillsides, flood-ridden areas, and thick construction areas, Contra Costa County needs to stabilize the soil to ensure structural damage prevention and ensure safe buildings.

Parking Lots, drive lanes and commercial surfaces that experience heavy traffic require soil that is stable when under the weight and exposure to the environment. We assess the interaction between vehicles, weather and drainage patterns on soil under the paved surfaces. These layers are strengthened by stabilization to avoid rutting, sinking or cracking due to repeated loading.
Reinforced soil can be used in business streets across Walnut Creek, Pleasant Hill and Brentwood to avoid deformation of pavements on hot summer days and water saturation during rainy seasons. We enhance the density and compaction of soil to provide a favorable surface on which parking lots remain smoother and strong over the years.
The hilly areas of the Contra Costa County, especially in the areas of Orinda, El Sobrante, and Martinez areas are susceptible to lateral movement down the hills because of steep grades, expansion of the clay, and seasonal rainfall.
We reinforce deeper layers in soil to slow down soil erosion through gradual down slope movement and may shift retaining walls, foundation strains or create uneven surface conditions.
Rainwater usually has the effect of weakening the upper layers of soil on the hillsides. Stabilization improves the cohesion in slopes making them not erode their structure during the heavy storms.
To avoid erosion of slopes that could undermine patios, lawns and lower-level supports, reinforced soil is protective in steep lots where the homes have been constructed on the ridges or on the edges of the canyons.

The soil stabilization prior to construction means that the new structure will commence on a solid predictable ground. In the various soils of Contra Costa, pre-construction reinforcement helps in excluding numerous problems in the long run.
Geotextiles offer an added strength to soil that is at risk of becoming moist, subjected to erosion, or overweight. They particularly the mixed soil profiles in Contra Costa are effective. Through geotextile fabrics, the weak soil layers are separated with reinforced material to enhance the stability and structure of soils.
They minimize soil erosion under driveways, walkways and retaining walls as water drains leaving the soil particles at place. Geotextiles when placed under pavements or structural pads are useful in ensuring that support is maintained and no shifting takes place. This renders them a great addition in both the hills and flatland project.
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.
