The topography of Lafayette, its rolling hills, neighborhoods along creeks, residential pockets with trees, makes the soil in this area change radically over a period of the year. Houses along Happy Valley Road, and the high streets along the Upper Happy Valley frequently stand on the slopes which change slightly with changes in moisture. In the meantime, those that are near downtown and in the Burton Valley, districts can be built on more compacted soils that are softened in wet winters and hardened unevenly in the heat of summer. These variations can cause stress to the structures particularly to the soft-story buildings which appear to depend on both the solid ground support and the lateral stability.
Even minor movements such as the cracks that creep by, floors that slightly tilt down, and other minuscule movements around access points can hint at the idea that the ground under your house is not doing its job reliably anymore. Since Lafayette houses were constructed many decades ago (pre-modern soil engineering), ground stabilization and retrofitting is a frequent procedure in stopping the expensive long-term structural movement. Our certified soft-story retrofit team offer solutions that are soil-based reinforcement solutions, which are used to ensure that your property is not damaged over time.

The soft story buildings need to be scrutinized correctly to find out the interaction between soil and structural action. Even small shifts in the terrain of Lafayette, rather diverse, undermine the stability of the first floor and endanger lateral movement. Our retrofit crew is also known to conduct detailed checking, sophisticated engineering techniques, plus strengthening plans that are based on the soil structure as well as the structural weight.
The owners of the property usually approach us because of noticing:
We test the entire system, including ground conditions and framing geometry and create structural upgrades which deal with every weak place.
Stabilization of soil enhances the ground under the structure and will provide the same level of support in terms of support during seasonal variations. We compare data on soil composition, water behavior, or slope conditions to decide which technique will provide the most credible results when recommending a method to use on Lafayette properties.

Unstable soils may interfere with the performance of a building in various ways. A loss of strength or uneven distribution of soil leads to the compaction of the soil structure, its inclination, or dislocation of the tops with main points of load. The hillsides of Lafayette are also rich with clay and the soil layers that are subject to moisture cycling give it the capability to move even without any significant weather occurrences.
Our team recognizes the causes of the soil instability such as moisture infiltration, compaction breakdown, slope displacement or soil erosion, and implements the solutions to mitigate the threat of structural stress. Framing up the foundation under your property reduces safety risks in the long term, as well as increases the life of your foundation and framing systems.
The problem of erosion is typical in Lafayette, particularly in regions where the yard is sloping, the retaining walls are old or the runoff channel is seasonal. In cases where soil is washed off, the soil will no longer be able to hold the building structure in the right manner and the floor will start to sag, the posts may become weak, or the framing in the soft-story buildings may become weak.
Our crew tracks the flow of water over and under your premises and then puts up stabilization measures that rejuvenate the soil and ensure that it does not erode in the future. We would safeguard the structure above by ground performance enhancement and moisture management, which avoid unnecessary stress and structural wear and tear in the long term.
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.
We needed crawl space repairs due to pests and moisture damage. They sealed it up, reinforced the beams, and added vapor barriersnow it’s dry and structurally sound. Excellent service from start to finish!
Our home needed retrofitting, and they did an amazing job reinforcing the foundation. They preserved the home’s character while making it structurally sound. If you need an expert who respects older homes, these are your guys.
We had a terrible experience with another contractor before finding these guys. They corrected the shoddy work, fixed our foundation properly, and treated us with respect. Finally, a business that stands by their word and does quality work.
We had a sinking foundation that caused doors to stick, but they fixed it with piers and proper leveling. Their team was professional, answered all our questions, and even followed up afterward. No more sticking doorsjust a solid, stable home.
A quick inspection by the crew revealed minor cracks that could’ve turned into big problems. They fixed them affordably and even gave tips to prevent future issues. So glad we called them before things got worse proactive and professional!
I was hesitant about foundation repair costs, but they gave a fair quote and stuck to itno surprise fees. Their crew worked fast, cleaned up perfectly, and even explained how to maintain our foundation. Honest and skilled highly recommend!
They saved us from a potential disaster when they spotted foundation issues during our home inspection. Their repair plan was clear, and the work was done efficiently without cutting corners. Now our floors are level, and we have peace of mind, great job!
