The town of Benicia sits on the Carquinez Strait and against a backdrop of rolling hills, and is perhaps one of the most scenic towns in the Bay Area, however, there is a darker side; water mismanagement. Poor drainage can have long-term effects on historic downtown buildings as well as residential neighborhoods located on hilltops and facing into the water. This is because of the common practices of saturated soil, pooling lawns, and wet basements that silently weaken the foundations and destroy the landscapes in the long-term.
We are a professional drainage company and deliver drainage services in Benicia, CA. that are capable of surviving the city weather and heavy soil that contains clay. We fit low-maintenance and long-lasting systems such as French drains and downspout extensions to yard grading and sump pump installation to ensure that homes are not in danger of being eroded, flooded, and damaged. Any project starts with a thorough analysis of the landscape of your property, so that the water flows in the right places.

It should not be costly to have quality drainage. Most homeowners are waiting to have repairs or upgrade done thinking that it will be too expensive but only to be caught up in bigger foundation or landscaping bills.
Our method is very practical and we provide affordable solutions to meet the needs of each property. Our low cost drainage repair and installation is guaranteed to provide long lasting protection without the need to spend a lot of unnecessary money.
The drainage performance is impacted by the coastal setting within Benicia. These are the most frequent issues that we assist the homeowners with:
Areas which receive rainfall but do not drain.
The soil is clay and retains water thus amplifying foundation stress.
Runoff transports soil down the slope destroying retaining walls.
Standing water under crawl spaces or patios.
Unsuitable grading holds the water in the landscaping.

A long life drainage solution is a combination of various elements that collaborate to transport water securely and effectively. The following elements are usually combined with us:
A combination of these systems will result in a continuous water management plan that will run efficiently in years- even during the wettest months of Benicia.
There are a lot of water issues beginning with the roofline. When the downspouts direct water too near the house it soaks into the soil around your house putting pressure against the walls of the foundations.
We place modified down spout extensions that direct the rain so that it flows away to avoid that possibility. It is an easy and efficient method of avoiding leaks, cracks and expensive basement repairs and keeping the yard dry.
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.
