Unilock Construction in San Antonio Heights, CA | Gold Star Contractors
We install, repair, and re-base Unilock paver driveways, patios, and retaining walls throughout San Antonio Heights. The single biggest difference here is the hillside: most flatland Unilock work never has to contend with decomposed granite slopes, county brush-clearance rules, or runoff that channels across a driveway apron after a winter storm. Call (833) 382-8544 for a free estimate from a contractor who knows how Unilock systems behave on graded foothill lots.
Why San Antonio Heights Residents Choose Us for Unilock Service
We’ve pulled apart enough failed paver bases in San Antonio Heights to know what the hills do to them. Brussels Block driveways that shifted downhill after one rainy season. U-Cara walls that leaned because nobody put geogrid behind them. Patio pavers that spalled on the north side of the house where shade and irrigation kept the joints wet year-round. None of this surprises us anymore, and that’s the point. Noel Carranza, our owner, grew up watching Orange County tract homes get rebuilt block by block, then spent years doing concrete and finish carpentry before building this operation. He treats every job like a slope problem first and a paver job second, because in San Antonio Heights that’s the only order that works for Unilock specialists.
We’re an independent contractor, not a Unilock dealer or authorized service arm. That matters. We specify what your site actually needs, whether that’s genuine Unilock units for a color match or aftermarket edge restraint and geogrid that outperform on decomposed granite soils. For Unilock sales and service guidance, we lean on our own field experience with the product lines, not a manufacturer script.

Common Unilock Construction Problems We Solve in San Antonio Heights
- Paver heave and rutting on steep driveways. When a Brussels Block driveway was built over a thin base without slope drainage, winter rain in San Antonio Heights pushes the courses downhill and leaves ruts at the apron. We over-excavate, re-compact, and add a drainage swale so water sheets away instead of undercutting the base.
- Efflorescence and spalling on shaded patio pavers. North-facing Beacon Hill patios tucked against the foothills stay damp from hillside shade and irrigation overspray. Without a proper polymeric sand re-sand, joints stay wet and the paver faces develop that white haze and surface flaking. We strip, clean, and re-sand with a polymer rated for that exposure.
- Retaining wall bulge or lean on decomposed granite. U-Cara and Copthorne walls built without geogrid or drainage aggregate lean within a few seasons on San Antonio Heights hillside lots. The soil here is unstable granite that holds water and expands. We rebuild with proper geogrid layers and a clear drainage column behind the wall.
- Polymeric sand washout at fire pits and hardscape edges. Santa Ana winds drive debris and embers across exposed patio edges. If joints weren’t topped off after install, the sand erodes and the pavers start to shift. We re-sand and, where fire safety is a concern, we adjust the layout to keep clearance from combustible vegetation.
- Driveway replacement after years of patches. Some San Antonio Heights driveways have been patched so many times that the subgrade is shot. We tell homeowners honestly when a full re-base beats another patch. Patching heaving pavers over a bad subgrade just moves the problem downhill.
Unilock Service in San Antonio Heights: What Local Conditions Mean for Your Equipment
San Antonio Heights sits in unincorporated San Bernardino County, and that changes how hardscape projects get approved. There’s no city building department here. Permits and brush-clearance inspections run through the county, and county defensible-space rules are not a suggestion. If you’re planning a paver patio or fire feature anywhere near the wildland edge, the layout has to account for clearance from combustible vegetation and structures, not just where the patio looks best from the kitchen window. A patio that would sail through review in a flatland city can get flagged here because the fire department wants ember-resistant spacing and defensible access. We plan Unilock in Upland and San Antonio Heights with those county rules from the first sketch, so you don’t get a stop-work notice on a job that was already halfway in the ground.
On one sloped lot off the foothill streets above San Antonio Heights, a homeowner’s Brussels Block driveway had heaved and rutted where runoff from the upper pad channeled across the apron after winter rains. We pulled the failed run, over-excavated and re-compacted the base with proper slope and a drainage swale, re-laid matched Brussels Block with edge restraint and polymeric sand, and tied the new apron into a re-graded approach so runoff now sheets away from the garage. No authorization claim, just a base built for the hill.
Unilock Models & Products We Service in San Antonio Heights
We work across the Unilock lines that show up most often on San Antonio Heights properties: Brussels Block and Brussels Dimensional for driveways and edging, Beacon Hill for flagstone-style patios, and U-Cara and Copthorne for segmental retaining walls. For repairs and re-lays, we source genuine Unilock units to keep color and dimensional matches tight. For the supporting materials, poly sand, edge restraint, geogrid, we use aftermarket products where they perform better on hillside soils than what was originally installed. We stock common jointing sand and edge restraint locally for faster turnaround on San Antonio Heights repair calls, and we order matched Unilock units in whatever lead time the supplier requires.

AfterUnilock Service Pricing in San Antonio Heights
Pricing depends on three things: how much base failed, how much slope we’re working with, and whether we’re repairing a section or replacing the whole run. Hillside work costs more than flatland work because the base prep is deeper and drainage detail is non-negotiable. Here’s where Unilock in Rancho Cucamonga and San Antonio Heights work typically lands:
| Service | Typical Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
A free estimate includes a site walk, a look at the existing base and drainage, and a line-item quote so you see exactly where the money goes. Call (833) 382-8544 to schedule yours.

FAQs – Unilock Construction in San Antonio Heights
Do Unilock pavers need a different base on a steep San Antonio Heights driveway than on a flat lot? Yes. A steep driveway needs deeper over-excavation, a thicker compacted aggregate base, and a drainage swale or channel at the apron. Without those, runoff undercuts the base and the pavers shift downhill within a season or two. Call (833) 382-8544 if your driveway is showing rutting at the bottom.
Will a Unilock paver patio meet San Antonio Heights brush-clearance and fire-safety expectations? It can if it’s designed for the site. County defensible-space rules require clearance from combustible vegetation and structures, and fire features need to be placed with ember-resistant spacing in mind. We design Unilock patios in San Antonio Heights with those rules in the plan from day one.
Why is my Unilock retaining wall leaning on my hillside lot? Nearly always because it was built without geogrid or a drainage column. The decomposed granite soils in San Antonio Heights hold water and expand, which pushes the wall forward. A leaning U-Cara or Copthorne wall usually needs Unilock repair in Claremont or San Antonio Heights with proper reinforcement, not just a face-level fix.
What’s causing white haze and loose joints on my Unilock patio pavers? That’s efflorescence from moisture staying in the joints, typical on shaded north-facing patios in San Antonio Heights where hillside shade and irrigation keep things damp. The fix is a proper clean and re-sand with a polymeric sand rated for that exposure. Call (833) 382-8544 for an assessment.
Can you match my existing Unilock pavers for a repair instead of replacing the whole driveway? In most cases, yes. We source genuine Unilock units for color and dimensional matches and re-lay the failed section with proper base and edge restraint. If the base under the whole driveway is failing, we’ll tell you honestly and quote the full re-base instead. Estimates are free.
