The unique combination of waterfront areas, old districts, and hillside houses of Benicia comprises a foundation setting, which is shaped by the sea moisture and the change in soil. Homes around the Downtown Benicia with its well-maintained Victorian architecture and tree-lined streets tend to have the soil slightly swelling throughout the rainy seasons. The houses along Southampton, Rose drive, or even the hillside overlooking the Benicia State Recreation Area can experience the effects of hill side forces and the altering groundwater trend. Our group realizes the role of these conditions in settlement and offers reinforcement solutions to be used in the course of long-term stability.
You may be living next to Military West or by Lake Herman Road or the side of an overgrown slope overlooking Southampton Bay, but with just a few signs, which can be separated trim, a sheet-rocking floor, or an obstinately stuck door, you might be able to know that your house is moving more deeply. The density of the soil, the changes in moisture and the older types of construction are contributory factors to the foundation behavior. We consider these factors highly and come up with reinforcement plans that are meant to ensure structural integrity of your home is preserved over decades.

The foundation underpinning is based on the knowledge of the interaction between soil, moisture and the distribution of the load beneath a structure. Soil in Benicia, particularly that around neighborhoods along Lake Herman or the Carquinez Strait can swell and shrink drastically. Natural cycles undermine the support as time goes by particularly in old houses with shallow footings.
We perform an analysis of the influence of each of these factors on the performance of the foundation: soil compaction, groundwater level, structural weight, and the age of the material. Through this, we are able to design a reinforcement strategy that will boost long term performance. Your house requires more support, or more specific stabilization, we develop solutions capable of tackling combined coastal and hilly terrain of Benicia.
Quick solutions are not enough when it comes to stability of the long term, a more personalized solution is needed, which will reinforce the areas when weakened, and which will prepare the groundwork to future changes in the soil.
Benicia is close to the strait that causes humidity, and change of moisture that can have softening effect on the soil. Our support systems are made in a way that they remain stable in varying conditions.
Homes in the Southampton Hills or on highways will also have to be more stabilized to conquer natural movement of the slope.
Age may leave older homes with uneven distribution of weight; we re-establish a satisfactory distribution of loads over the long term.

The soil erosion, seasonal dampness and hillside disposition may erode the foundation support system beneath you bit by bit. We strengthen weak areas by detecting early signs of movement, before more severe damage is caused.
Symptoms that indicate the possibility of the necessity of underpinning are common and include:
My reinforcement strategies can stabilize areas which are sinking and create balance in addition to avoiding further movement under your house.
The commercial buildings within Benicia; be it along First Street, within Southampton Business Park, and/or the proximity of industrial areas in Bayshore Road tend to be located on soil that does not respond well with residential lots. The bigger structures have more weight to bear and thus the initial signs of settlement are even more of a serious concern to consider.
Underpinning is used to support these buildings by strengthening soils that have weakened or compacted. Footing depth, soil density and structural weight are evaluated to decide on the most appropriate type of reinforcement. We assist in ensuring that the commercial property is not at risk of long-term settling, and provide safe surroundings to the tenants, customers, and workers.
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.
