Serving Corte Madera, CA and surrounding areas. (628) 212-4120
Your hillside is slowly losing ground every rainy season. We build concrete retaining walls with proper drainage and deep footings so the soil stays exactly where it belongs.
Concrete retaining walls in Corte Madera hold back soil on sloped lots using poured concrete or concrete block - most residential projects take one to two weeks of active work, plus two to four weeks for the town permit review before work begins.
Most homeowners in Corte Madera reach out after noticing soil creeping toward the driveway or a neighbor's property, or after an existing wall has started to lean or crack. With Marin County's clay-heavy soil and wet winters, a wall built without proper drainage will face enormous water pressure after a heavy January storm. Getting that drainage designed correctly from the start is what separates a wall that lasts 50 years from one that fails in five. For projects where the wall also needs to sit on a properly engineered base, our concrete footings service ensures that foundation is built right.
We handle the Town of Corte Madera permit application as a standard part of every retaining wall job. You should not have to navigate the building department yourself - and unpermitted retaining wall work can surface on a home inspection and create real problems when you sell.
If you notice dirt slowly spilling over the edge of a slope onto your driveway, walkway, or a neighbor's property, the ground is not being held in place. In Corte Madera's hillside neighborhoods, this slow creep tends to worsen each rainy season. A retaining wall stops the movement before it becomes a bigger, more expensive problem.
A retaining wall that is starting to tilt forward, show horizontal cracks, or push outward at the base is under stress it was not designed to handle. This is especially common with older walls in Corte Madera built before current drainage standards. Do not wait for a full collapse - a leaning wall is a warning sign that repair or replacement is overdue.
Standing water collecting at the bottom of a hillside after winter storms means water is moving through the soil with nowhere to go. That saturated soil becomes heavier and more likely to slide. Corte Madera's wet winters make this pattern especially common, and a properly drained retaining wall can redirect that water before it causes damage.
If cracks are appearing in a patio, garden path, or along the edge of your foundation near a slope, soil movement may be the cause. Shifting ground puts uneven pressure on anything built on top of it. Catching this early and installing a retaining wall can prevent far more expensive structural repairs later.
Every retaining wall we build starts with a footing excavated below the depth where seasonal soil movement can affect it. This is the step most budget contractors skip - and it is the single biggest reason walls fail early. We set rebar, pour the footing, build the wall, and install gravel backfill and perforated drain pipe behind it before any soil goes back in.
For homeowners whose sloped property also needs a structural base for a new addition or accessory structure, our slab foundation building service can be coordinated alongside retaining wall work so the excavation and grading happen in a single mobilization. This saves time and reduces disruption to your yard.
We build both poured concrete walls and concrete masonry unit (block) walls. The right choice depends on your site's slope, aesthetics, and budget. Both can be built to last 50 years when designed and installed correctly. The American Concrete Institute sets the standards that guide how both types are designed and built. We work to those benchmarks on every project.
Best for homeowners who need maximum strength on steep slopes or where a clean, continuous surface matters for the finished look.
Best for homeowners who want a cost-effective option that still delivers decades of service when built on a proper footing with drainage behind it.
Best for homeowners with a long slope who want to create multiple flat terraces for gardens, patios, or usable yard space on a hillside lot.
Best for homeowners with an existing wall that is leaning, cracking, or failing - we demo the old structure and build a correctly engineered replacement.
Corte Madera sits at the base of the Marin hills, and a significant portion of the town's residential lots slope toward the street or toward neighboring properties. For these homeowners, a retaining wall is not a luxury - it is the difference between a stable yard and one that gradually erodes onto the driveway, sidewalk, or a neighbor's fence line. The steeper the lot, the more engineering thought goes into the wall's design, which is why site-specific assessment matters so much here.
The soils across much of Marin County contain a significant amount of clay. Clay swells when wet and shrinks when dry - a cycle that repeats every rainy season and puts real stress on anything buried in the ground. A contractor unfamiliar with local soil conditions may design footings that are too shallow or skip gravel backfill in favor of native soil, both of which dramatically shorten a wall's useful life. The UC Cooperative Extension Marin has documented these soil conditions extensively, and they are a real factor in every wall we design for this area.
Corte Madera receives most of its rainfall between November and March, and those storms can be intense. We serve neighboring communities including Larkspur and San Anselmo where hilly terrain and clay soils create the same drainage challenges. Homeowners in Mill Valley face similar hillside conditions and benefit from the same drainage-forward wall design.
You reach out and we respond within one business day to schedule a site visit. We walk your slope, look at the soil and existing conditions, and ask what you are hoping to accomplish - whether that is stopping erosion, creating flat terrace space, or replacing a failing wall.
You receive a written estimate that breaks down labor, materials, permit fees, and drainage work. In Corte Madera, most retaining walls require a building permit - we handle that application on your behalf and build the fee into the estimate so there are no surprises.
We submit the permit application to the Town of Corte Madera's Building Division. Approval typically takes two to four weeks. Use that window to clear the work area of planters, furniture, or stored items and confirm equipment access with us.
The crew excavates, pours the footing, builds the wall, and installs drainage behind it - gravel and perforated pipe that channels water away from the structure. After the concrete cures, a town inspector signs off, the site is backfilled, and we walk you through what to watch for in the first year.
We handle the Town of Corte Madera permit process, drainage design, and cleanup - you just tell us what you are dealing with.
(628) 212-4120Every wall we design includes gravel backfill and perforated drain pipe from the start - not added on after the fact. In Corte Madera's wet winters, drainage is what keeps a well-built wall standing. We do not build walls that treat drainage as optional.
Our footings are dug deeper and reinforced to account for the seasonal soil movement that is normal in this area. Shallow footings are the most common reason retaining walls fail within five years here. Homeowners across Marin County trust us because we design for local conditions, not national averages.
We submit the permit application to the Town of Corte Madera's Building Division on your behalf. A permitted wall gets inspected and documented, which protects your home's value and your safety. You should not have to navigate that process yourself.
We serve Corte Madera, Mill Valley, Larkspur, San Anselmo, Tiburon, San Rafael, Novato, Sausalito, Fairfax, San Francisco, Richmond, and Berkeley. Knowing how terrain and soil vary across these 12 communities is what allows us to design walls that fit the actual conditions on your lot.
When a retaining wall holds up through five rainy seasons without cracking, leaning, or letting water seep through in the wrong places, it is because the drainage, footings, and backfill were all done correctly. That is what we focus on - the parts you cannot see but will absolutely feel over the life of the wall.
Deep, reinforced footings that anchor retaining walls and structures into stable ground below the depth of seasonal soil movement.
