The county of Contra Costa is a very diverse area. The houses of such locations as Orinda, Lafayette and Walnut Creek are usually located in inclining land that is affected by clay soils which end up being hardened during rainy seasons and being shrunk when temperatures are high. The settlement of the property in Concord, Martinez and Pleasant Hill can be due to historic soil fill or the gradual compaction of the land under preexisting construction. In the meantime, the buildings around the Delta and the Carquinez Strait have soil conditions that are influenced by the moisture and changing groundwater levels.
In the neighborhoods of San Ramon, Danville, and Hercules, homeowners can observe small initial signs of movement like floors no longer being level, hairline cracks on ceilings or walls on the outside starting to part by a small margin. Such problems usually point at the change of the soil behavior under the foundation. We are able to assist in the restoration of stability that homes are reliant on all over Contra Costa County with critical evaluation and specific reinforcement.

Not every foundation crack is similar and it is necessary to know what they are portending. Cracks in the foundation may be common in the Contra Costa County, where the soil type could be clay on the hillsides or solidly filled and the part of the foundation settles at a different rate. Stair-step or horizontal fractures, especially, can imply that the movement downwards is straining the structure.
Our team considers the pattern and cause of the crack and would identify the most suitable reinforcement method. The cracking can be experienced in sloppy sections such as the town of Moraga or in the ridges of El Sobrante, where the pressure of the ground on the foundation moves. Where the soil is flatter in location like in Antioch or Pittsburg the cracks can develop as a result of the uneven compression of the soil. We prevent movement that causes the cracks by stabilizing the home at the base which in turn stabilizes the entire structure.
Increased families, remodels, and aging structures are also creating new structural requirements on homes in the Contra Costa County. Underpinning also increases the size of a foundation to make it capable of bearing the weight that is put on it, both instantaneously and in the future.
Houses that get extensions of rooms, second floors, or beamed out living rooms usually need to be strengthened to avoid sinking in the future.
Numerous houses that were constructed several decades ago are based on weak foundations. We strengthen them to ensure that they are able to support the current loads of structure with a high degree of confidence.
The reinforcement of hillside properties must consider the slope pressure and density of soil, so that the support is long term.

There are localities in the Contra Costa County that are in a continuous movement of the soil over the hillside, or because of adaptation to change in moisture, or as a result of older construction methods. When these are combined together the ground under a house may become loose and move the structure.
Pay attention to the following typical signs of the necessity of reinforcement:
Stabilizing damaged soil and reinforcing structural points of interest we are able to minimize further settlement and ensure that your home no longer suffers in the long-term.

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.
