Located on the rolling hills of the East Bay, with the creeks and greenbelts of Saint Marys and Campolinda as its borders, Moraga is a lovely location to reside in, however, its landscape will necessitate adequate drainage systems. Soil erosion, unwanted water surrounding the foundations, and flooding are common characteristics of sloped lots, compacted clay soil and sudden winter storms.
The drainage systems that are designed and installed by our drainage specialists are designed with the landscape of Moraga in mind. We ensure that the unwanted water runs off your house safely and efficiently, whether it is hillside runoff control or full installations of French drains. Be it in wet lawns, patio puddles, or foundation puddles we will develop a solution that helps to secure your home in the long run.

French drains and surface drains were designed to control water although they are utilized differently. Surface drains deal with apparent runoff, or the runoff that can be seen right after the beginning of heavy rainfall, and French drains deal with the runoff that seeps out of the ground and settles around foundations.
Our crew will examine the slope of your property, the type of soil, and drainage flow patterns and then suggest either of the two. Most of the Moraga houses that we offer integrate systems to achieve full coverage of water surface and underground water.
Being located at an elevation and having little absorption to the soil, Moraga has some particular drainage issues that should be considered by homeowners:
Water runoffs that accumulate on the low sides of upper slopes tend to cause hydrostatic pressure.
Clay soil retains the moisture and does not allow the lawns to dry evenly.
Poor grading causes water to move towards and not away water paved areas.

A good drainage system is based on more than a pipe or a trench. It consists of synchronous components that control the water flow throughout your own property. Key components include:
Every component of the system combines to make sure that your system is functioning reliably every storm season.
A French drain may be easy to install, but it can be trivialized, and the slightest mistakes will render it useless. Laying of pipes without a good slope, poor quality of gravel, or lack of protection of the line by fabric filtration are the most widespread errors.
Our technicians are using established installation techniques that do not block and collapse. We also make sure that the slope of every trench is graded properly and that all the layers, including filter fabric and gravel base, are constructed in such a way that they will work as long as possible in clay-heavy soil in Moraga.
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.
