Orinda homes have the stunning scenery of Glorietta and Sleepy Hollow, but with wooded hills and winding creeks, some of the prettiest landscapes in the East Bay, and some of the worst drainage difficulties. Rains in the winter season and the rough topography tend to cause water to flow downhill and accumulate at the base of foundations, lawns, and patios. In cases where the ground fails to absorb the excess water, the consequences may be dire: wet soil, concrete cracking, moulds and erosion that poses a threat to the stability of the property in the long term.
That’s where we come in. We offer special drainage services in Orinda, CA which are designed to fit the topography of the city and clay soil. Our design and installation project is based on French drains and sump systems, slope stabilization, and improvement in grading. Any project begins with the meticulous examination of the property, we research on the variation of elevation, the distribution of water and the condition of the soil and then design the plan that directs the movement of water out of your house in an effective and permanent manner.

A properly built French drain is long-lasting in spite of decades, but only when it is well maintained. Silt, root growth and debris can slowly diminish the flow of water, forcing the drain line to clog or overflow.
To maintain optimal performance, our team suggests that the inspections and professional cleanings should be done regularly. We also install shield fabric liners and access points that enable the maintenance to be quicker and more efficient. When properly maintained, your French drain will last 20 years or longer keeping your property safely.
The geography of Orinda has a number of challenges that would determine the design of drainage systems. The following are the criteria that we use to analyze each home:
The rainwater speeds up, which causes soil erosion and heightens risks of soil movement.
Less permeability retains water at the surface forming saturation areas.
The stormy winter has impounding snow and drains and floods shallow or aged drainage systems.

Any effective drainage system depends on certain components which collaborate to direct water in a safe environment. The most frequently used elements are:
These features can form a self-sustaining system that prevents ruined floors, ceilings and windows caused by moisture quietly, year after year when combined correctly.
Precision is the most important aspect of French drain. The initial step involves first identifying the lowest spots where the water may gather, and tracing a drainage route that is effective. An excavation is then made and lined with filter cloth and gravel used to facilitate regular flow of water.
Lastly, a perforated pipe is placed and enwrapped and then covered with clean stone and top soil. All the parts are designed to fit in the right slope and to be filtered to make sure your drain works perfectly even in the most stormy days in Orinda.
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.
