Unilock Construction in Upland, CA | San Bernardino Contractors
We provide independent Unilock paver, wall, and step construction across Upland and nearby communities, including Rancho Cucamonga Unilock service, from the Euclid Avenue corridor up into the 91784 foothills. What makes our Unilock work different here is simple: we plan every base around what’s actually buried under Upland lots, not what the survey map shows. If you’re pricing a Brussels Block driveway or a Uni-Stone retaining wall, call (855) 473-5620 and we’ll give you a straight, line-item estimate.
We’ve laid Unilock pavers, walls, and steps on Upland properties for years as an independent installer. That means we know how their systems behave on clay-heavy north-side soils and under Santa Ana wind loading. We follow Unilock’s published base-assembly and compaction specs, and we’re clear about one thing: we are not authorized, sponsored, or endorsed by Unilock. We’re a full-service general contractor that happens to work with Unilock sales & service because the product line holds up when the base underneath is built right.
Why Upland Residents Choose Us for Unilock Service
Ruben Castillo, owner of San Bernardino Contractors, spent his weekends as a kid watching his uncle frame garages and reroof houses on a shoestring budget in San Bernardino’s Westside. He got serious about load paths and structural work at San Bernardino Valley College, and he’s spent the better part of two decades running whole-home remodels across the Inland Empire. That background matters when you’re building a Unilock driveway on a Upland lot with old citrus-ranch fill under it.
Homeowners in Upland and surrounding areas like Montclair call us because we treat a paver installation like a structural project, not a landscaping task — and we offer Unilock repair in Montclair with the same approach. We buy genuine Unilock pavers and Uni-Stone wall units for color and dimensional match. We pair them with proper base aggregate, edge restraint, and polymeric sand. And when we bid a job, we tell you what’s actually going to happen under the pavers, including what we’ll do if we hit abandoned irrigation lines or an old well casing. If it’s not built right the first time, you’re just paying for it twice.
Serving Upland service area means we’re familiar with every ZIP from 91784 to 91786, and we know which lots tend to hide surprises.

Common Unilock Construction Problems We Solve in Upland
- Edge and joint failure on driveways. When the base was compacted over old citrus-ranch fill instead of excavated, pavers heave and shift after the first hot-dry and wet cycle. We dig out the bad material, re-compact, and reset the edge restraint properly.
- Efflorescence and salt bloom on Brussels Block and Beacon Hill surfaces. Upland’s hard inland water plus irrigation overspray sitting on unsealed pavers leaves a white haze. We clean and seal where it makes sense, and we fix the drainage that’s feeding the problem.
- Wall block settlement and bulging on Uni-Stone retaining walls. Sloped foothill lots built without geogrid tie-back start leaning within a couple of seasons. We rebuild with proper reinforcement or stabilize before the wall gets worse.
- Polymeric sand washout and rutting. We see driveways pitched toward the house or against abandoned ag-era irrigation lines that still channel water. That water moves the sand and eventually the pavers. We correct the grade before re-sanding.
- Old concrete aprons failing under new paver loads. On Euclid Avenue corridor properties, we often find cracked concrete beneath a paver overlay that was never supposed to be there. If the slab is failing, the pavers above will fail with it.
Unilock Service in Upland: What Local Conditions Mean for Your Equipment
Upland is a rare Southern California city that still has real citrus-era ranches and groves on its north side, especially in the 91784 foothill ZIP. A large share of construction work here is renovation and rebuild on properties where contractors work around mature avocado and citrus trees, old irrigation, and unpermitted ag-era outbuildings. That means a Unilock driveway or patio in Upland doesn’t start with laying pavers over existing grade. It starts with excavation and base correction.
In the 91784 foothill ZIPs, we routinely uncover buried citrus-ranch irrigation lines, shallow wells, and old shed slabs under what looks like a normal residential lot. On a foothill property off the Euclid Avenue corridor, our crew pulled up an old cracked concrete apron and found abandoned citrus irrigation piping and a shallow well casing under the drive. We dug out and re-compacted the base, reset a Unilock Brussels Block driveway with proper edge restraint and polymeric sand, and graded it away from the house so runoff no longer pooled at the garage. That’s the difference between a paver job that lasts and one that needs a redo in three years.
Hot, dry inland summers and Santa Ana wind events also shape how we build here. We use fire-resistant details on hardscape near the house and make sure drainage moves water away from structures, not toward them.
Unilock Models & Products We Service in Upland
We install and repair the Unilock lines most common on Upland driveways, patios, and walls. Brussels Block is the tumbled, dimensional paver we see most on driveway and walkway projects. Beacon Hill is the flagstone-style paver for patios and wall caps. Uni-Stone is the cast-concrete retaining wall block system for sloped lots. Town Hall is the permeable structural paver for driveways and patios where drainage matters.
For parts, we buy genuine Unilock pavers and Uni-Stone wall units so color and dimensions match the existing field. We don’t chase aftermarket paver substitutes on a repair. The base aggregate, edge restraint, and polymeric sand we stock are spec’d for Upland’s clay-heavy soil and hot-dry climate, so turnaround on common repairs stays short.

FAQs – Unilock Construction in Upland
Typically no, and we’ll tell you why on site. If the concrete underneath is cracked or settling, the pavers above will mirror those problems within a season or two. In Upland, where old citrus-ranch fill and abandoned irrigation lines run under many lots, overlaying pavers on bad concrete just hides the base failure. We remove the old slab when it’s compromised, re-compact the base, and build the paver system properly. Call (855) 473-5620 and we’ll give you an honest read on whether your slab can stay or has to go.
Edge shifting almost always comes back to the base, not the pavers themselves. On the north side of Upland, especially in 91784, the ground under many homes is old citrus-ranch fill with buried irrigation lines. That fill was never compacted to structural standard. When the hot-dry summer shrinks the soil and winter rains swell it, the outer rows of pavers move because the base moves. We excavate, re-compact, and install proper edge restraint to lock the field in place. Call (855) 473-5620 for an exact quote, and we’ll inspect the base before quoting anything.
Yes. We keep defensible space in mind when siting paver patios and walkways near the house, and we use non-combustible materials and drainage details that don’t trap embers or channel water toward the foundation. Unilock pavers themselves are concrete, so they’re not adding fuel, but the way we grade and edge them matters for fire and wind resilience. Call (855) 473-5620 and we’ll walk your property with that lens.
That’s efflorescence, a salt bloom that happens when water moves through concrete and carries minerals to the surface. In Upland, the combination of hard inland water and irrigation overspray on unsealed pavers makes it worse. We can clean and seal the surface, but the real fix is stopping the water that’s feeding it. We’ll identify the source, correct the drainage or overspray, and then address the surface. Call (855) 473-5620 for an assessment.
Yes, and that’s where we see the most preventable failures. Uni-Stone retaining walls built on sloped foothill lots without geogrid tie-back start bulging within a couple of seasons. We build those walls to hold, with proper reinforcement and drainage behind the block. If you have an existing wall that’s leaning or bulging, call (855) 473-5620 and we’ll tell you whether it can be stabilized or needs a rebuild.
