Hillside erosion, a leaning wall, or a yard that disappears into a slope? We build concrete retaining walls built for Marin County terrain - with drainage, permits, and footings done right.
Concrete retaining walls in San Rafael hold back soil on sloped lots so it does not erode, shift, or wash onto adjacent property - most residential wall projects take two to five days of active construction, plus a week of cure time and two to four weeks for the required city permit.
A large share of San Rafael homes sit on hillside lots where soil retention is a structural concern, not just a landscaping choice. If your slope is losing ground after each winter storm, or if an existing wall has started to lean, the underlying problem does not go away on its own. Concrete retaining walls are among the most durable solutions available - properly built with drainage and a deep footing, they can last 50 years or more.
Homeowners who add a retaining wall often pair it with concrete floor installation to finish the leveled space behind the wall. If grade changes call for steps, concrete steps construction connects different elevations safely.
If your retaining wall is no longer plumb - tilting forward, bowing in the middle, or showing horizontal cracks - it is under more soil pressure than it was designed to handle. In San Rafael, this often appears in late winter after months of rain have saturated the soil. A wall that is already moving will not correct itself.
Mulch, soil, or gravel migrating down your slope and collecting near your foundation or your neighbor's yard is a sign the slope lacks adequate retention. San Rafael's wet winters accelerate erosion on hillside lots, and what starts as a minor nuisance can become a significant problem within a few seasons.
Water collecting against your home's foundation during or after a rainstorm may mean that the slope behind your house is directing water toward the structure. A retaining wall with proper drainage can redirect that water and protect your foundation from long-term moisture damage - a real concern in San Rafael's clay soils.
If the edge of a paved surface near a slope is cracking, dropping, or separating from the main surface, the soil beneath is shifting. This is common on San Rafael hillside properties where driveways run along a cut slope. A retaining wall stabilizes the ground and stops further movement before the damage spreads.
We build poured concrete and concrete block retaining walls for residential properties in San Rafael and across Marin County. Every wall starts with proper footing excavation below stable soil - this is the step that determines whether a wall holds for decades or starts to lean within a few years. We place reinforcing steel, pour or lay the wall, and install drainage behind it before backfilling in compacted layers.
For steeper hillside lots, we often build tiered walls in steps rather than one tall single structure - this distributes the load more evenly and is typically easier to permit. Once a wall creates a level terrace, many homeowners use that space as a patio or garden, which pairs naturally with our concrete floor installation work. Walls that involve significant grade changes sometimes need concrete steps construction to make the terraced areas accessible and safe.
Best suited for taller walls and steep hillside lots where maximum soil pressure resistance is needed.
A good fit for tighter spaces or shorter walls where a large-form pour is not practical.
Ideal for steep slopes where a single tall wall would require extensive engineering and permitting.
San Rafael is built on hillside terrain. Neighborhoods above downtown, the Sun Valley area, and properties near the Marin County Civic Center frequently have sloped lots where soil retention is not optional. Marin County clay soils make the situation more complex - they swell during wet winters and shrink in dry summers, which puts repeated stress on footings and the soil behind any wall. A contractor who does not account for this during drainage design and footing depth is building a problem that shows up within a few rainy seasons.
San Rafael also requires permits for most retaining walls, and the process involves the city building division - homeowners should budget time for that approval before work begins. We work throughout the city and serve neighboring communities including Vallejo and Novato, where hillside terrain and clay soils create similar conditions. Local knowledge is not a marketing phrase here - it is the difference between a wall that lasts and one that leans.
Every retaining wall job is different, so we always visit your property before quoting a price. We look at the slope, soil, site access, and drainage needs. Expect a response within 1 business day.
For walls over four feet in San Rafael, we prepare the required drawings and submit the permit application on your behalf. Approval typically takes two to four weeks - we keep you updated throughout.
We excavate for the footing, set forms, place reinforcing steel, and pour the concrete. Most residential walls take two to four days of active construction. The footing cures before the wall goes up.
After the concrete cures, we install gravel backfill and perforated drain pipe behind the wall, then compact the soil in layers. A city inspector signs off on permitted work before we hand the yard back to you.

(628) 234-2121San Rafael's steep lots require equipment, access planning, and soil knowledge that flat-lot contractors often lack. We have worked on hillside properties throughout the city - from the neighborhoods above downtown to Sun Valley - and we know what those sites demand before we even start digging.
We handle the City of San Rafael permit application from start to finish. A permitted, inspected wall gives you documentation that protects your home's value and shields you legally if the wall ever affects a neighbor's property.
Every retaining wall we build includes gravel backfill and a perforated drain pipe behind it. Drainage is the single biggest factor in long-term wall performance, and in San Rafael's clay-heavy soils it is not something we leave to chance.
Our California contractor's license is active and verifiable on the CSLB website. We carry full liability and workers comp coverage, which means you are not exposed if something goes wrong during construction on your hillside property.
The Portland Cement Association identifies drainage as the leading cause of premature retaining wall failure - we build it in on every project, not as an upgrade. Combining that with local permit knowledge and hillside site experience means you get a wall that is engineered for what San Rafael actually throws at it, not a wall designed for flat lots in a drier climate.
