Richmond Concrete Experts builds retaining walls, steep driveways, patios, and decorative concrete for Orinda homeowners. Orinda is across the Berkeley Hills from Richmond, about ten miles away, and its rolling, oak-covered terrain makes almost every project a hillside project.
About Orinda
Orinda is a city of about 19,500 people in Contra Costa County, on the east side of the hills along State Route 24. It was mostly ranches and summer cabins until the Caldecott Tunnel opened in 1937 and made year-round commuting practical. The city incorporated in 1985 and is part of the area locals call Lamorinda, along with Lafayette and Moraga.
Hillside Lots Need Engineering
On Orinda's slopes, concrete work almost always involves holding back soil or managing water:
Retaining walls
Creating a flat yard, a patio, or a parking area usually means cutting into the slope and building a wall. Walls over 4 feet measured from the bottom of the footing, or any wall supporting a driveway, slope, or structure above, need a permit and engineered plans. Drainage behind the wall is what keeps it standing through wet winters. See retaining walls.
Steep driveways
Long, steep driveways need traction finishes, reinforcement, thicker sections where vehicles turn, and drainage that carries runoff away instead of down the driveway.
Patios on uneven ground
A patio on a hillside may need a stepped design, a seating wall that doubles as a retaining wall, or a raised slab on footings.
Orinda's Weather
Because of its hills and elevation, Orinda has strong microclimates. It often gets more winter rain than nearby areas, and low-lying spots can see cold, frosty mornings, while summer heat waves hit harder than on the bay side of the hills. That means good drainage, proper curing on hot days, and a sealer to protect the surface.
Decorative Finishes
Many Orinda projects call for stamped concrete, integral color, or exposed aggregate that fits a landscaped yard. See stamped & exposed aggregate for options.
