With such a city, which is constructed on hilly slopes and unstable soil, the management of water is not an option but a necessity. Ranging in the fog-laden mornings of the Sunset District to the 15.3-degree down pouring, which are whipping along the hillsides of Twin Peaks, the topography in San Francisco is one of the most difficult to drain in California. Due to the olden foundation of the houses, concrete slabs, etc. most houses have problems such as pooling of water, soil erosion, and slow formation of cracks which decrease stability with time.
Our drainage solution team is based in San Francisco, CA and it will serve the city with its topology and unforeseeable rainy weather. A tailored system is developed by us to control both surface and subsurface water effectively, and save your house against structural stress and at the same time maintain the beauty of your landscape. Our careful planning and durable construction materials are used to protect homes in San Francisco which is a constant fight between water and gravity.

At the expense of temperature and moisture, concrete slabs expand and contract. Poor drainage causes the water to be piled up under the slab that makes the soil to be soft leading to unbalanced settling. With time, such movement will result in cracks and structural change.
We have underground drains, which will intercept water before it gets on your slab. Our constant moisture in the soil and reduction of hydrostatic pressure will reduce cracking and will keep your foundation strong over decades.
Even the most developed systems require a periodical adjustment to remain efficient. The topography and the steep active coastline of San Francisco can slowly change the soil and stressing materials. Drainage continues to work perfectly using the maintenance programs that we have.
We are checking out all drains and outlets as to their blockages, water retention, or damage.
We re-calibrate slopes and clear debris before every rainy season to ensure that slopes are full.
We replace the old systems with new piping and flow capacity and also the waterproofing.

Our group employs the latest technology in engineering and accurate installations to conquer the most intricate drainage problems of San Francisco. Each of the details is designed efficiently and long-lasting, such as slope, or the location of the outlet.
Integrated Multilayer Systems: Surface, subsurface and foundation level drainage is combined into one unified network.
Smart Elevation Mapping: Instruments guided by lasers give us an opportunity to compute precise slope gradients, resulting in perfect flow direction.
Strong Cement-reinforced Materials: Our elements are corrosion-resistant and resist salty air and moisture caused by constant fogs.
This will ensure that you have a system constructed to withstand the fluctuating climate in the city and have your property dry and structurally stable.
The patchwork of shifting sandy coastal soil, thick clay areas, and artificial fill spaces of the city imply that no similar properties drain. A one-size fits all solution just does not apply in this case.
All systems are developed after a thorough soil and elevation study. Regardless of whether your property is located on the sandy loam by beach or on the rocky clay hills, our custom designs will make sure that the water flows and the foundation is safe.
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.
