Excavation, Grading, Drainage & Concrete Contractors — East Bay & Central Valley
From backyard drainage to municipal site work — Class A General Contractor serving the East Bay, Central Valley, and Sierra Foothills.
What We Do
Solves All Engineering is a Class A General Contractor specializing in excavation, grading, drainage, and masonry. We self-perform our core trades and have the experience to run complex projects involving multiple subcontractors, permitting, and regulatory compliance on both public and private works.
What We Build
Residential Services
Drainage problems. Retaining walls. Pavers. Concrete. Sport courts. If your yard needs serious work done right, we bring the equipment and expertise to get it done.
Commercial & Site Work
Grading subcontractor. Prime contractor. Municipal site prep. We have the Class A license, the equipment, and the public works experience to deliver on commercial projects that demand more than a pickup truck and a shovel.
Land Stewardship
Some properties need more than a gardener. Weed abatement, vegetation management, erosion control, and riparian work — managed by someone who understands the land and the regulations that govern it. No pesticides. No shortcuts.
Built on Experience
Matt grew up in the East Bay and spent over a decade in environmental remediation and water management — first as a field tech, then as a project manager overseeing complex work involving grading, excavation, drainage systems, and contaminated soil cleanup. That background is the foundation of Solves All Engineering. Around him he's built a crew that reflects the same standard: experienced stone masons, equipment operators, concrete finishers, and carpenters who take pride in the work they put their name on.

"Matt and his foreman Dan came to our rescue between two atmospheric rivers, installing a 45-foot French drain, 8 feet deep in places. Three weeks later, everything is dry. Professional, efficient, good communicators, and fairly priced." — Google Review, East Bay Homeowner
"Matt put my mind at ease immediately. He started talking solutions from the get-go, not trying to sell me his service. He proposed a solution, showed up on time, completed the job on schedule, and stayed on budget." — Angi Review, East Bay Homeowner
"Matt and his crew have an unusual combination of qualities for a contractor — extremely knowledgeable and professional, but also responsive, honest, and trustworthy. Matt is as responsive now, after the job is complete, as he was before it started." — Angi Review, East Bay Homeowner
