Serving Mill Valley, CA and surrounding areas. (628) 257-3534
Mill Valley Concrete is a licensed concrete contractor serving San Rafael, CA with foundation installation, driveways, patios, retaining walls, and concrete steps. We handle Marin County permits, clay soil conditions, and hillside drainage requirements on every project, and we have been working in this area since 2022.
San Rafael has a large share of homes built between the 1940s and 1970s, many of them on hillside lots or clay-heavy flatland soils. When a foundation needs repair or full replacement in this city, the engineering must account for seismic zone requirements, expansive soils, and drainage from the surrounding hills. Read more about our foundation installation process and what to expect.
San Rafael driveways range from steep hillside approaches above downtown to flat street-level aprons in Terra Linda and the Canal neighborhood. We design drainage into every pour, use broom or textured finishes on sloped surfaces, and handle city permit requirements for new and replacement driveways.
San Rafael's dry summers make outdoor living practical for most of the year. We account for clay soil movement and drainage on every patio job, so the surface stays level and crack-free through Marin's wet winters and dry summer months.
Hillside properties above downtown San Rafael and near Dominican University regularly lose soil to winter runoff. A properly engineered concrete retaining wall stops that erosion, creates usable flat space on a sloped yard, and protects the home's foundation from lateral soil pressure.
Slab foundations are common on the flatter areas of San Rafael, including parts of Terra Linda and the Canal neighborhood. We build reinforced slabs designed for Marin County soil conditions, with proper drainage and sub-base preparation to resist the clay soil movement that cracks slabs over time.
Homes on the hillside streets of San Rafael often have long stair runs from the sidewalk to the front door. Concrete holds up through Marin's wet winters without the rot and replacement cycles that wood stairs require, and a non-slip surface finish keeps footing safe on damp mornings.
San Rafael is Marin County's oldest and largest city, incorporated in 1874, and a large portion of its homes were built before 1980. Many of those houses, particularly in the hillside neighborhoods above Fourth Street and around Dominican University, sit on steep lots with original foundations that have been in the ground for 60 or 70 years. Foundation movement, cracked driveways, and eroding retaining walls are common maintenance issues across this housing stock, and the solutions require an understanding of what the soil actually does here.
Clay soils are common throughout San Rafael and the broader Marin County area. These soils absorb water and swell during the wet season, then dry out and shrink in summer. That back-and-forth puts steady stress on any concrete structure from below. A driveway or patio poured without proper base preparation will develop cracks within the first few years as the clay moves underneath it. A foundation that was not designed to accommodate seasonal soil movement can shift enough to cause door and window misalignment, wall cracks, and long-term structural problems.
San Rafael averages around 37 inches of rain per year, most of it falling between November and March. The hillside neighborhoods above downtown concentrate that runoff, which adds drainage pressure on foundations and flatwork throughout the wet season. Homes in the flatland Canal neighborhood face a different version of the same problem, since low elevation means water moves slowly and drainage systems need to be designed carefully to prevent pooling near foundations.
Mill Valley Concrete has been pulling permits through the City of San Rafael Building Division since 2022 and regularly works on properties across the city's distinct neighborhoods. San Rafael is the Marin County seat, and its building department processes permits for a wider range of project types than smaller surrounding cities, including commercial flatwork, foundation replacement in historic residential neighborhoods, and retaining walls on steep hillside parcels.
The city has genuinely different terrain from one neighborhood to the next. The postwar ranch homes in Terra Linda sit on relatively flat land with fairly uniform drainage patterns. The hillside neighborhoods above Mission Avenue and near Dominican University of California have narrow lots, older homes, and grades that require pump trucks for concrete delivery. The Canal neighborhood near the water has its own drainage considerations because of its low elevation. Knowing which part of San Rafael a job is in shapes how we quote, plan, and execute the work.
We also serve homeowners in San Anselmo, which sits just west of San Rafael up Sir Francis Drake Boulevard, and in Larkspur, directly south along the Highway 101 corridor.
We reply within 1 business day. Tell us the type of work, your San Rafael address, and your general timeline. A short conversation gives us what we need to schedule the right kind of site visit.
We visit your property before quoting. For San Rafael projects, we check lot slope, soil conditions, drainage patterns, truck access, and any tree proximity. Foundation jobs also include a review of the existing structure. You get a written estimate that reflects your actual site, not a round number.
We submit the City of San Rafael permit application on your behalf. Foundation work also requires coordinating a structural engineer. We give you a clear start date and permit timeline upfront, so you know what to expect. No work begins until the permit is approved.
The crew completes the project per permit conditions, removes equipment and debris, and walks the finished work with you before the job is closed. You keep your permit documentation for insurance and resale records.
We serve all of San Rafael, CA. Free on-site estimates, permits handled, and written quotes before any work begins.
(628) 257-3534San Rafael is the county seat of Marin County and its largest city, with a population of roughly 61,000. Incorporated in 1874, it is one of the oldest cities in California and has a dense, varied urban core centered around Fourth Street downtown. The Frank Lloyd Wright-designed Marin County Civic Center sits on the northern edge of the city and is one of the most recognized buildings in the Bay Area. Home values in San Rafael range from around $900,000 to over $1 million at the median, and roughly 55 percent of housing units are owner-occupied.
The city's neighborhoods vary significantly. Terra Linda and Sun Valley are suburban areas with postwar ranch homes on modest lots, built primarily in the 1950s and 1960s. The hillside streets above downtown have older Craftsman and Spanish-style homes on steep, wooded lots. The Canal neighborhood in the southeastern part of the city is denser, with more multi-family housing from the 1960s and 1970s and proximity to the water. Each of these areas presents different concrete work conditions, from flat slab pours in Terra Linda to hillside retaining wall and foundation jobs near the upper streets off Mission Avenue.
Neighboring San Anselmo to the west shares many of the same hillside and clay soil characteristics as San Rafael's upper neighborhoods. We serve both cities and approach each job with the same site-specific planning that Marin County terrain demands.
