Unilock Construction in San Antonio Heights, CA | Polaris Contractors
We install and repair Unilock paver driveways, patios, and retaining walls throughout San Antonio Heights and Unilock in Rancho Cucamonga as an independent contractor. What sets our Unilock work here apart is simple: we read the hillside first. The upper slopes of San Antonio Heights sit on ancient landslide deposits, and a paver job that ignores that fact fails within two winters. Call (855) 473-6535 for a free estimate on your Unilock project.
Why San Antonio Heights Residents Choose Us for Unilock Service
Rick Sondermann grew up in Corona del Mar and spent nearly three decades building along the coastal slopes before bringing that hillside experience to the foothill communities. He learned the trade from a finish carpenter father who believed in doing things once, and that philosophy drives how we approach every Unilock installation in San Antonio Heights. We’re not a paver crew that happens to work here; we’re a full-scope general contractor that understands base prep, drainage, and grade on terrain that punishes shortcuts. One team, full scope, from the roof down to the pavers.
We’re an independent Unilock service provider, not a manufacturer affiliate. That means our recommendations are based on what actually holds up on these slopes, not what a brand rep wants sold. Need a Beacon Hill retaining wall that won’t bulge in five years? We’ll spec the geogrid correctly. Need a Brussels Block driveway that doesn’t rut at the garage apron? We’ll rebuild the base instead of layering pavers over the problem. Our Unilock sales & service approach works because we diagnose before we build.

Common Unilock Construction Problems We Solve in San Antonio Heights
- Base failure and rutting on sloped driveways. Pavers laid over under-compacted, expansive soil migrate downhill after the wet-dry soil cycle that defines San Antonio Heights summers and winters. Joints open, pavers rock, and the driveway eventually looks like a washboard. We rebuild the base with compacted aggregate before re-laying anything.
- Beacon Hill retaining wall shearing and bulging. On the upper slopes, walls built without proper geogrid and gravel drainage start leaning within a few years. The ancient landslide deposits beneath these lots make a bad base choice fatal. We re-set walls with grid, drainage, and correct cap courses.
- Efflorescence and salt bloom on Brussels Block and Richcliff surfaces. The dry-summer-to-winter-rain swing pulls minerals through the paver face, leaving white residue that sealer alone won’t fix. Poor drainage makes it worse. We address the moisture path first, then treat the surface.
- Polymeric sand washout at the bottom of terraced lots. Winter runoff concentrates along the lower edges of terraced San Antonio Heights properties, and without a swale or drain to intercept it, the joint sand simply washes away. We install drainage intercepts and re-sand with materials that hold.
- Sunken patios over uncompacted fill. Many 1950s – 1970s ranch homes here had patios added over loose fill. Once the soil cycles through a few wet seasons, the pavers drop unevenly. The fix is base reconstruction, not more sand.
Unilock Service in San Antonio Heights: What Local Conditions Mean for Your Equipment
San Antonio Heights is an unincorporated foothill community at the base of the San Gabriel Mountains, perched on ancient landslide deposits near the San Andreas Fault. That geology isn’t abstract; it’s the reason even a modest paver patio or retaining-wall build can trigger Los Angeles County geologists to demand a soil report and caisson-style footings. Flatland paver crews never price that in, and homeowners get surprised when a $6,000 patio becomes a $14,000 engineered project. We’ve worked through those county requirements enough times to know exactly when they’ll apply and how to sequence the work so you’re not stuck in permit limbo. ZIP code 91784 sits outside any city building department, so LA County oversees everything, and the review process moves differently here than in incorporated cities a few miles away. If your Unilock project involves a retaining wall over four feet, a hillside cut, or significant grade change, plan for geotechnical review. We’ll guide you to the right material and the right engineering, so the paver face is the last decision we make, not the first.
Unilock Models & Products We Service in San Antonio Heights
We install and repair the full range of Unilock hardscape systems most common in San Antonio Heights: Brussels Block for classic tumbled driveways and walkways, Beacon Hill Flagstone for retaining walls and terraced planters, Richcliff for larger-format patio slabs, and Town Hall for compact dimensional pavers that handle driveway traffic well. On the parts side, we match Unilock’s own block profiles, caps, and geogrid for structural fidelity, and we use quality aftermarket polymeric sand and drainage components where they outperform OEM equivalents in our specific soil conditions. For fast San Antonio Heights turnaround, we keep common Brussels Block and Beacon Hill profiles in our local supply chain, so a repair doesn’t stall waiting on an order from the manufacturer. Built to the brand’s specification, installed to ours.

AfterUnilock Service Pricing in San Antonio Heights
Unilock work depends entirely on what’s underneath the pavers. A simple patio on stable, compacted soil is straightforward; a driveway on expansive hillside fill is a different job. Here’s what current market pricing looks like for the projects we handle most in San Antonio Heights:
| Project | Typical Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Home Addition | $45,000 – $130,000 |
Geotechnical reports, caisson footings, and significant base reconstruction will push toward the upper end of those ranges, and on the upper slopes of San Antonio Heights, those costs are more the rule than the exception. Our free estimates include a site walk where we check slope, drainage, and existing base condition, so you get a written line-item quote before any work starts, whether you need Unilock service in Montclair or here in the Heights. Call (855) 473-6535 to schedule yours.

FAQs – Unilock Construction in San Antonio Heights
Yes, we can, but it requires engineering that flatland wall installers skip. Walls on the upper slopes of San Antonio Heights generally need a soil report, geogrid reinforcement, gravel drainage behind the block, and sometimes caisson footings. We’ve built Beacon Hill walls on these exact deposits, and the difference between a wall that lasts and one that bulges is entirely in the prep work. Call (855) 473-6535 and we’ll walk your slope and tell you what the county will require.
Your driveway is almost certainly sitting on expansive soil that was never properly compacted before the pavers went down. On San Antonio Heights slopes, the wet-dry cycle swells and shrinks that soil, and pavers migrate downhill with every cycle. The fix is base reconstruction: pull the pavers, excavate the loose fill, compact a proper aggregate base, and re-lay everything with drainage that channels water away from the foundation. Re-laying pavers over the same failed base will sink again within a few seasons.
For a patio, usually not. For a retaining wall over four feet, or any wall on a hillside with questionable geology, yes. San Antonio Heights is an unincorporated LA County island, so county geologists review any project that triggers slope or landslide concerns. We handle the permit paperwork and coordinate with the county so you don’t have to navigate that process alone. Your project, managed start to finish.
Pavers themselves are already non-combustible – concrete pavers don’t burn. The wildfire concern in San Antonio Heights is less about the paver surface and more about surrounding vegetation, defensible-space clearing, and how your hardscape interacts with ember paths. We can design patio and driveway layouts that create natural firebreaks around the home perimeter, which matters in the foothill severity zones. Pair that with fire-resistant landscaping choices and you’ve done the practical work.
We direct the water before it hits the joints. On terraced San Antonio Heights lots, winter runoff concentrates along the lower edges and erodes polymeric sand within a season or two. We install swales, channel drains, or French drains along the uphill side of the hardscape so the water has a path that isn’t through your paver joints, then re-sand with a polymer that holds in our specific soil chemistry. For an exact plan, call (855) 473-6535 – the site walk is free.
