Located on the coastal verge of the San Pablo Bay, Hercules is a neighborhood whose nature and neighborhood architecture coexist alongside each other yet can change very fast once water starts accumulating in places where it should not. Drainage problems in this area between steep hillside projects, old foundations, and coastal rains usually begin on a small scale and develop silently, with cracked patios, wet lawns, and small leaks at the foundation, which do not manifest themselves until after the storm.
Our team provides professional drainage services in Hercules, CA, which is constructed to fix the problem of water at the source level. We do not simply transport water, but we control water. All of them are designed to fit the layout of your property, its elevation, and the soil type – the systems will provide peace of mind and long-term security. It might be fighting the standing water, moisture intrusion or dampness under the basement but our mission is easy, we want to make your home strong, dry and strong in all seasons.

Proper drainage is among the most important defensive measures to protect damage to homes. By collecting water around your property, it soaks into soil and puts a strain on your foundation walls – eventually cracking, leaking or moving.
We are putting in place tested systems that will divert the surface and ground water effectively. Whether it is underground piping or grading modifications, we will ensure that your foundation is dry and your outdoor areas are operational during all rainy seasons.
Each property in Hercules has its own water movement problem with particularities around coastal moisture and hillside grading. All elements of water management are also balanced in our integrated systems to form sustainable protection.
French drains are installed and perforated pipes placed under trouble areas to direct the groundwater to safe places.
Correction in the slope also makes sure that the rainfall moves outwards rather than accumulating on the side of the walls or patios.
Waterproof membranes are used to make drainage parts leak free and crack free.

Even the superior systems require care to remain effective. We have maintenance programs to ensure that your drainage is operating to perfection due to years of rain, runoffs and soil changes.
Routine Inspections: We survey slope stability, drainage performance and foundation conditions pre- and post-rainy season.
Performance Optimization: As required, we adjust slope angles and flow channels to accommodate the varying rain patterns.
Preventive Repairs: Whether it is clearing blockages or strengthening joints, we make sure that your system works at the highest efficiency throughout the year.
This preventive maintenance ensures that your investment remains safe to defend your home – silently, surely and over the decades.

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.
