The terrain of Concord, a combination of hilly neighborhoods, developed suburban zones and broad commercial streets all has varying soil conditions that change in varying ways according to the season. Homes close to Treat boulevard, Cowell Road, Clayton Road, and the areas surrounding Lime Ridge are usually located on soils which are comprised of clay which swell to very large sizes following a time of rainfall and contract during hot summers. In the meantime, houses around Todos Santos Plaza, Sun Terrace, and Monument Boulevard area could be built on old fill or compacted soil, which loses its strength over time, exposure to moisture, and repetitive settling.
Such natural developments affect the way the land underpins foundations, walkways, soft-story buildings and exterior developments. The first indications include slight cracks formed along the pads of concrete or run-off of water following a storm, or even soil creeping away along the sideboards which are primary signs that the ground under your house is gradually moving. Our team provides soil stabilization services to the specific terrain of Concord, which serves to assist the companies in keeping the ground very strong and stable to support their property owners at all times of the year.

The soil type around Concord is clay soils and this soil is usually good in terms of load bearing capacity in the presence of the right amount of moisture however; it becomes erratic when it is subjected to seasonal changes. When clay is wetened, it swells; when it dries, it becomes shrunken. These movements may result in observable structural stress.
We check the behavior of the clay beneath your property and apply stabilizing measures that minimise expansion, contraction and settlement. With the assistance of bettering soil consistency and moisture ratio, we will assist in preserving long-term foundation dependability and the threat of broad structural cracks.
Stabilization enhances the ground under your home and makes it stable even despite the changes in weather patterns and moisture cycles. We research soil density, compaction conditions and responses of the ground to the changes of the season before any treatment. This guarantees your property with the reinforcement that is needed to perform long.
We strengthen layers of soil to ensure that foundations do not shift upon weight of the structure and that they get less in settlement and uneven settlement.
Stabilization practices are used to control amount of moisture uptake and hence the extent to which the soil expands when wet.
Let us control the movement of the soil so that the foundation does not tip, crack, or slide away at critical structural points.

Concord has a large number of properties which are in need of soil stabilization prior to retrofitting or foundation reinforcement. Weakness of the soil under soft-story building or multi-level structure influences the load paths and poses a threat of structural disequilibrium.
The owners of buildings turn to us when they observe:
We apply the exact diagnostic equipment to analyze the stability of soil and formulate retrofit plans to enhance the stability of the soil and the lower-level supporting system of the building structure.
The process of the cracking of building interiors or exteriors is frequently initiated by very slight soil alterations. When there is a change in the ground, such as through expansion, erosion, or improper compaction, the structure built on the ground starts to move and visible cracks can be seen along the floors, walls or foundations.
Our team determines the action of soil behavior on the structure and strengthens the ground to prevent any further movements. After soil has been stabilized, there is very little chance that the building will have spreading cracks, distorted framing, and permanent structural movement. This preventive measure assists in ensuring security as well as safeguarding property.
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.
