The scenic beauty of the natural sceneries in Lafayette (the wood-covered hills around the Reliez Valley up to the silent residential areas around Happy Valley Road) comes with a price that is well known to many residents in the East Bay area, to control the water run-offs and drainage of the soil. The topography is quite rolling, and the soil is dense clay; thus, it is easy to accumulate around houses and lawns and cause floods, erosion, and foundation issues without taking action.
The team we offer offers drainage systems that fully safeguard the homes against the entry of water and movement of soil in the Lafayette area, with their solutions being designed to suit individual needs. Whether your lawn is always wet due to storms or your yard always fills up, we will develop a drainage system that is designed according to the features of your property and the topography of Lafayette.

Such a slight inconvenience as poor drainage can be a few puddles in the rain, a wet spot at the foundation, but it can soon lead to grave structural and landscaping losses. The extensive saturation of soil undermines retaining walls, ruins hardscapes and makes your foundation to move or crack.
We assist homeowners to solve their water problems before they go out of control. Our preventive drainage system will save you money on safeguarding the structure of your home, landscape design and the value of your property. Early intervention is cost effective.
The hills and climate of Lafayette have unique drainage problems and are not similar to its neighboring cities. The following is what will be special to water management in this area:
The heavy soil contains water which slows down natural absorption and enhances pooling.
Houses constructed in hilly slopes will tend to develop off-hill streams of water towards the foundations or the drive to the house.
Winter rainfall comes in torrents and cannot find its way to old drainage systems.

We design our drainage systems in terms of performance and durability. The best solutions that we use in Lafayette properties are as follows:
All solutions are chosen and fitted depending on the layout and the profile of the soil in your property, meaning that it is long-term defense against water damages.
Drainage systems are not equal in all. A poorly fitted or small system may fail in one rainy season and water can go around and bring even greater havoc. The design of proper drainage needs to be made to understand the conditions, the slope, and the patterns of runoff of individual property.
Our group deals with accuracy in designing drainages. We examine grading, survey water flow and select the appropriate materials in order to achieve greatest efficiency. All of the installations that we finish in Lafayette are designed to be lasting and effective, even in the most rainy months.
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.
