Unilock Construction in San Antonio Heights, CA | San Bruno Construction
We provide independent Unilock installation and repair across San Antonio Heights, from paver driveways to retaining walls and patio hardscapes. The one thing that makes our Unilock work different here is simple: we plan every project around hillside drainage, county permitting, and fire-zone requirements before a single paver goes down. That’s the difference between a patio that holds its lines for twenty years and one that shifts after the first wet season. Call (866) 472-1908 for a free estimate.
Why San Antonio Heights Residents Choose Us for Unilock Service
We’ve installed and repaired Unilock pavers and walls on our General Contractor in San Antonio Heights hillside lots long enough to know which product lines hold up on graded, fire-zone terrain and which fail when a base wasn’t built for slope runoff. Brussels Block, Beacon Hill, Bristol Valley, U-Cara retaining walls – we’ve worked with all of them up here, and we’ve seen what happens when flat-lot specs get applied to terraced land. Noel Carvalho, our owner, runs every hardscape project the same way he runs a whole-home remodel: start with the ground underneath, get the water moving away from the structure, then lay the surface. We’re an independent contractor, not a Unilock dealer, and our credibility comes from the installs we’ve actually completed in San Antonio Heights, not from a manufacturer’s marketing department. That’s why we carry OEM Unilock units, matching edge restraint, and polymeric sand rather than substitute brands – the color and dimensional tolerances need to match the existing field, or you’ll see the patch forever.

Common Unilock Construction Problems We Solve in San Antonio Heights
- Pavers tipping and settling on hillside driveways. Brussels Block and Beacon Hill pavers shift when the base was compacted for a flat-lot spec instead of a sloped, drained one. We see this constantly on driveways cut into San Antonio Heights grades, where water moves downhill fast and finds every soft spot in the sub-base.
- Polymeric joint sand washing out during seasonal downpours. Rain that races down San Antonio Heights slopes flushes sand out of paver joints, leaving open seams and shifting units. We reset joints with sand spec’d for steeper grades, then verify the drainage path actually carries water off the field.
- Spalling and efflorescence on Bristol Valley pavers. Older flat patios here were sometimes poured over a slope without a drainage path, trapping water under the field. The moisture works its way up through the pavers, causing surface flaking and white mineral staining. We rebuild the base with proper slope before replacing the surface layer.
- Bulging or leaning U-Cara retaining walls. A prior wall that lacked proper geogrid and footing for saturated hillside soil will lean within a few wet seasons. Often this ties back to unpermitted work the county later flags. We rebuild with pier footings and geogrid spec’d for San Antonio Heights soil conditions.
- Foundation cracks and drainage failures around hardscape. Hillside lots here drain toward the valley, so a previous owner’s unpermitted retaining wall or flat patio is frequently the actual cause of a slide or foundation crack. We find the root cause before touching the surface, then coordinate the correction through San Bernardino County inspection.
Unilock Service in San Antonio Heights: What Local Conditions Mean for Your Equipment
Every Unilock driveway, patio, or wall in San Antonio Heights 91784 is permitted and inspected through San Bernardino County, not a city building department, because the community is unincorporated. That changes the entire project. County reviewers want to see slope-stability and drainage addressed on terraced hilltop lots that would never need it down the hill in Unilock in Upland. So when we repair a heaving patio or rebuild a leaning wall on a hilltop street near Mount Baldy, the scope regularly includes engineered footings, geogrid reinforcement, and a drainage plan that moves water toward the downhill swale. A flat-lot crew might lay pavers in a day and walk away. We can’t. The county won’t sign off, and more importantly, the ground won’t hold. Fire-zone requirements add another layer: San Antonio Heights sits in a high fire-hazard-severity zone in the wildland-urban interface, so new construction and additions tied to hardscape work must meet Chapter 7A ignition-resistant standards. Good construction doesn’t announce itself – it just works, year after year. Up here, that means building for water, fire, and gravity from day one.
Unilock Models & Products We Service in San Antonio Heights
We install and repair the Unilock product lines most common on San Antonio Heights properties: Brussels Block for driveways and walkways, Beacon Hill for a tumbled, aged look on patios, Bristol Valley for large-format paver fields, and the U-Cara retaining wall system for terraced landscapes. Our parts approach is strict: genuine Unilock units, matching Unilock edge restraint, and spec-appropriate polymeric sand – never substitute brands. When a wall or paver base has failed, we repair and rebuild the base and drainage before recommending replacement of the surface. Pavers themselves are rarely the thing that gave out. For broader Unilock sales & service across the region, we bring the same repair-first discipline to every job.

FAQs – Unilock Construction in San Antonio Heights
Yes, in most cases we can match new Unilock units to an existing field, provided the original product line is still in production. We source genuine Unilock units in the same color and dimensional profile, then reset the surrounding area with matching edge restraint and polymeric sand so the patch blends instead of announcing itself. If the original line has been discontinued, we’ll show you the closest current match and give you an honest read on whether a full-field replacement makes more sense. Call (866) 472-1908 for an exact assessment – the estimate is free.
No. San Bruno Construction is an independent hardscape and general contracting crew that installs and repairs Unilock products. We are not authorized, sponsored, or endorsed by Unilock, and we don’t need to be – our work in San Antonio Heights speaks through the installs still holding their lines after years of slope runoff and seasonal downpours. We choose genuine Unilock in Rancho Cucamonga units because the color and tolerance match matters, not because a manufacturer told us to.
Most driveway or patio rebuilds in San Antonio Heights take five to ten working days, including base replacement, drainage correction, paver installation, and joint sanding. Hillside jobs with retaining-wall rebuilds or county-required engineering reviews can run longer – we’ll give you a specific timeline at the estimate, based on your grade and what the county will want to see.
Yes. Because San Antonio Heights is unincorporated, wall and major hardscape work is permitted and inspected through San Bernardino County, not a city hall. We prepare the plans, submit the permit applications, and walk the project through inspection – including correction permits where a previous owner’s unpermitted wall or flat patio is the root cause of the failure. You won’t have to chase the county; we do.
Repairs on hillside properties typically run between $3,500 and $11,000 for a paver patio rebuild and $7,000 to $18,000 for a full driveway replacement, depending on how much base and drainage work the grade requires. A leaning U-Cara wall with failed footings will land somewhere in the paver-install range plus engineering if the county requires it. Call (866) 472-1908 and we’ll walk your property and give you a line-item number before any work starts.
