Unilock Construction in Redwood Shores, CA | San Bruno Construction
We install and repair Unilock paver driveways, patios, and retaining walls throughout Redwood Shores, and the thing that separates a lasting Unilock job here from a callback is drainage. Redwood Shores sits on bay fill with a perched water table, so the base under the pavers matters as much as the pavers themselves. We’re an independent crew, not Unilock-affiliated, and we’ve been laying these systems across the Peninsula long enough to know what the ground here does to a shortcut. Call (866) 472-1908 for a free estimate on any Unilock project in Redwood Shores.
Why Redwood Shores Residents Choose Us for Unilock Service
Unilock makes a specific product with specific base requirements. We know the line because we install it, and we know Redwood Shores because we work here. Noel Carvalho, our owner, grew up off El Camino Real in San Bruno and trained in construction technology at Skyline College, where he learned to read plans and think through load paths before a tool comes out of the truck. That’s the mindset we bring to every paver field in the 94065 ZIP. We buy Unilock units directly, cut and lay them to spec, and match edge restraints and caps so color, thickness, and dimensional tolerance stay consistent across the whole field. When a homeowner in Redwood Shores calls us about a settled driveway or a patio that’s lipped along the house edge, we start with the subgrade, not with a quote for a tear-out. You can read more about our approach on our Unilock sales & service page.

Common Unilock Construction Problems We Solve in Redwood Shores
We see the same failure patterns repeat across the 1980s and 90s build-out of Redwood Shores, and almost all of them trace back to water. Here’s what we fix most often:
- Pumping bases under paver fields. The perched water table under the engineered fill keeps the aggregate base saturated. A compacted-but-not-drained base pumps water up through the joints when you drive over it, and the field settles unevenly. This happens on Redwood Shores fill lots far more than on sloping inland grade in San Carlos or Belmont.
- Long, flat swales and lippage. Bay-mud consolidation and original builder-era fill mean a paver field laid over unstabilized subgrade develops low spots and lippage even when the base was compacted to spec at install. We lift, re-grade, re-drain, and re-lay rather than quoting a full replacement until the subgrade proves it can’t hold.
- Polymeric joint sand washing out. Fog and onshore wind keep joints damp for long stretches along the bayside, so joint sand cures slowly and can wash before it sets. That drives refill and re-sanding callbacks on driveways close to the water, and it’s why we watch the forecast and staging closely on those jobs.
- Efflorescence and corrosion on wall units. Saturated fill wicks moisture and salts up through Brussels Dimensional Stone and concrete edge restraints, leaving white deposits and corroded fasteners. We see it most on seat walls and low retaining walls in Redwood Shores where the grade holds water against the back of the wall.
- Mismatched heights from mixed manufacturers. When a previous repair used a different manufacturer’s units, the field develops mismatched heights and joint widths. We spec genuine Unilock units and matching Unilock edge restraints to keep the field consistent.
Unilock Service in Redwood Shores: What Local Conditions Mean for Your Equipment
Here’s the thing about Redwood Shores that a generic Unilock page won’t tell you. Redwood Shores is a single-ZIP, master-planned community built out mostly on bay fill from the 1980s onward, and large parts of it sit in mapped flood zone and BCDC-jurisdiction bayfront. That means a paver driveway or patio that changes grade or increases impervious coverage can hinge on geotech and flood/sea-level-rise review, not just an over-the-counter hardscape permit from the city. We hit this on a Brussels Block driveway replacement in a bayside neighborhood of Redwood Shores. After a winter storm, the original fill subgrade was pumping water and the paver field lipped along the house-side edge. We pulled the units, over-excavated below the perched water table, installed a free-draining open-graded base tied to a French drain that sheds toward the street, and reset the Brussels Block with fresh Unilock edge restraints. The field has stayed flat through two wet seasons since. That drainage detail is the difference between a driveway that lasts and one that needs leveling every spring. If you’re planning a Unilock project anywhere in Redwood Shores, start with the water, not the paver color. We cover all of this in more depth on our Redwood Shores service area page.
Unilock Models & Products We Service in Redwood Shores
We work with the full Unilock lineup that shows up on Unilock in San Mateo and Peninsula homes. Brussels Block is the workhorse for driveways and patios, with that tumbled edge that hides minor settling. Beacon Hill Flagstone gives the large-format flagstone look for patios and walkways. Brussels Dimensional Stone handles seat walls and low retaining walls. And Copthorne, with its clay-brick look, fits the Mediterranean stucco facades that dominate Redwood Shores. For parts, we use genuine Unilock units and matching edge restraints and caps. Mixing manufacturers on a repair is where mismatched heights and joint widths start, so we don’t. We keep common Unilock field units staged locally for faster turnaround on Redwood Shores repairs, which means less time waiting on a truck from a distributor.

FAQs – Unilock Construction in Redwood Shores
Sometimes, but not without checking what’s under it first. The original fill in Redwood Shores can be decades old and already consolidating. If a compaction test and geotech read show the subgrade is stable and we can tie in drainage below the perched water table, we lay over it. If it’s pumping or soft, we over-excavate and rebuild the base. Call (866) 472-1908 and we’ll tell you which situation you have after a site visit.
It can, yes. Because parts of Redwood Shores sit in mapped flood zone and BCDC-jurisdiction bayfront, a project that changes grade or increases impervious coverage may trigger geotech and flood/sea-level-rise review. We’ve handled that process here before and we’ll tell you up front if your job falls into it. Call (866) 472-1908 and we’ll walk you through what applies to your lot.
Fog and onshore wind keep joints damp for long stretches along the Redwood Shores bayside, so the sand cures slowly and can wash before it sets. It’s a chronic issue on driveways close to the water. We re-sand with proper curing conditions and sometimes adjust the joint width or sand type. Call (866) 472-1908 and we’ll take a look at what’s causing yours specifically.
Copthorne reads as a clay-brick paver and matches the Mediterranean stucco facades you see throughout Redwood Shores. Brussels Block is a strong neutral for most of the 1980s and 90s build-out. Beacon Hill Flagstone suits patios and larger outdoor spaces. We’ll bring samples to your Redwood Shores home so you can see them against your actual stucco and trim. Call (866) 472-1908 to set that up.
Almost always a base-and-drainage repair before it’s a replacement. We lift, re-grade, re-drain, and re-lay the Unilock units rather than quoting a full tear-out until the subgrade proves it can’t hold. In Redwood Shores, the subgrade is usually the problem, not the pavers. Call (866) 472-1908 for an honest read on yours.
