Unilock Construction in North Tustin, CA | San Mateo Construction
We’re San Mateo Construction, an independent Unilock hardscape contractor serving North Tustin homeowners with paver driveways, patios, and retaining wall systems. If you’re planning a Unilock project or repairing an existing one in North Tustin, call (855) 901-7266 for a free estimate. One thing sets our Unilock work here apart: we know North Tustin is an unincorporated county island, which means your paver project often lands on Orange County Building Department’s desk, not Tustin’s. That permitting layer catches a lot of out-of-town contractors off guard, and it shapes how we plan every job.
Why North Tustin Residents Choose Us for Unilock Service
Our familiarity with Unilock’s product lines comes from years of installing and repairing them, not from reading a catalog. Noel Carrington, our owner, grew up around concrete work in the Bay Area and studied construction technology before spending three decades in residential and light commercial building. That background matters when a Unilock paver driveway in North Tustin sits on a 1960s lot with original drainage and reactive clay subgrade. We understand how Unilock systems behave here because we’ve torn out and rebuilt enough of them on the exact kind of lots that dominate North Tustin. We match OEM Unilock units and accessories rather than substituting generic pavers, and we’re straight with you when a failing base means rebasing is the right call, not a cosmetic overlay.

Common Unilock Construction Problems We Solve in North Tustin
- Efflorescence and salt bloom on Brussels Dimensional and Beacon Hill pavers. North Tustin’s inland heat pulls moisture up through paver beds when base drainage is marginal. The white, chalky residue isn’t a paver defect; it’s water wicking through and depositing minerals on the surface. We address it at the drainage and base level, not with surface sealers that mask the problem for a season.
- Edge and joint-sand loss on driveways from Santa Ana wind scour. Dry-season shrinkage opens joints, and Santa Ana winds scour the sand out fast. Pavers shift at the apron and turning radius. We use Unilock edge restraints and properly graded joint sand to keep units locked, and we’ll add a channel drain at the apron where the original base has no outlet.
- Retaining wall block facing spalling on U-Cara systems. On 1960s – 70s lots with poor footing drains, wildfire-related soil movement and water pressure behind the wall separate joints and spall facing units. We rebuild with proper drainage and Unilock geogrid through slope transitions.
- Color fading and surface etching on colored units under intense inland UV. North Tustin gets a lot of sun, and older Unilock units show it. When matching replacements, we account for fading so new units don’t stand out against the existing field.
- Shallow-root reactive clay upheaval lifting joints in older driveways. The soil under many North Tustin homes expands and contracts with moisture. That movement telegraphs through the base and lifts paver joints. A proper compacted base with geogrid is the fix, not just re-screeding sand.
Unilock Service in North Tustin: What Local Conditions Mean for Your Equipment
North Tustin is a patchwork of unincorporated county islands surrounded by incorporated Tustin and Santa Ana, so a single Unilock paver driveway or patio project routinely needs Orange County Building Department plan check rather than the neighboring city’s. Many homeowners are surprised their “Tustin” address isn’t a Tustin permit. We’ve also seen lots that straddle county and city jurisdiction lines, meaning a single addition can need both Orange County and Tustin approvals. That’s a paperwork trap that adds weeks if not caught at plan check. For Unilock work specifically, this affects retaining walls over 4 feet, driveways with significant slope changes, and any project with drainage improvements. On a hillside lot off Cowan Heights Drive, our crew tore out a cupped 1990s paver driveway and reset it on a new compacted base with Unilock Brussels Dimensional units, fresh edge restraint, and geogrid through the slope transition. We added a channel drain at the apron because the original base had no outlet, which is why the joints had been blowing out every dry season and the wall behind it kept separating. That job needed Orange County plan check for the drainage improvements, and we pulled the permit before the first shovel went in the ground.
Unilock Models & Products We Service in North Tustin
We install and repair the Unilock lines most common in North Tustin: Brussels Dimensional pavers for driveways, Beacon Hill pavers for patios and walkways, U-Cara retaining wall systems, and Bristol Valley wall block. Our approach is OEM-first. We match Unilock units and accessories including edge restraints, joint sand, wall caps, and geogrid. Mixing manufacturers undermines laying pattern and structural performance, so we don’t do it. If a base is failing because of drainage or subgrade rather than the pavers themselves, we’ll tell you straight that rebasing beats a cosmetic overlay, even though that changes the job scope.

FAQs – Unilock Construction in North Tustin
Do I need a Tustin permit or an Orange County permit for a Unilock paver driveway in North Tustin? Most North Tustin Unilock paver driveways go through Orange County Building Department plan check, because the area is unincorporated county land, not within Tustin city limits. Retaining walls over 4 feet, driveway slope changes, and drainage improvements all trigger county review. We handle the permitting on your behalf and budget the processing time into your schedule. Call (855) 901-7266 and we’ll check your specific address before you commit.
Why is my Unilock Brussels driveway turning white and shifting at the edges? The white residue is efflorescence, and the shifting edges are usually joint-sand loss from Santa Ana wind scour and dry-season shrinkage. Both trace back to base drainage and edge restraint, not the paver units themselves. We repair the base, install Unilock edge restraints, and re-sand with the proper joint material. Call (855) 901-7266 for a free inspection.
Can you match existing Unilock Beacon Hill or Bristol Valley pavers for a repair? Yes. We source OEM Unilock units in the same size and color family, and we account for UV fading on the existing field so new units blend rather than stand out as bright patches. If the original batch is no longer manufactured, we’ll show you the closest match and confirm it before ordering. Call (855) 901-7266 with photos of your existing pavers and we’ll get you a match quote.
Are Unilock pavers a good fit for fire-defensible landscaping on a canyon-adjacent North Tustin lot? Unilock concrete pavers are non-combustible and work well as a fire-defensible hardscape zone when paired with proper drainage and minimal vegetation near structures. For canyon-adjacent North Tustin properties, we recommend a paver patio or walkway zone at least a few feet wide against the home, with a compacted base and no mulch or combustible planting within the first 5 feet. Hot, dry Santa Ana conditions make this a practical choice. Call (855) 901-7266 to review your lot.
What does a Unilock paver patio run on a large North Tustin lot? A Unilock paver patio in North Tustin typically runs $3,500 – $11,000 depending on size, access, base prep, and whether we’re building retaining walls or drainage into the scope. Large 1960s – 70s lots often have room for a bigger patio, which brings the price toward the higher end. Call (855) 901-7266 for an exact quote, estimates are free.
