Unilock Construction in Upland, CA | Polaris Contractors
Polaris Contractors provides independent Unilock construction service across Upland, CA, from flat-valley patio builds near Euclid Avenue to foothill retaining-wall work in 91784, and San Antonio Heights Unilock service as well. What makes our Unilock work different here is that we scope drainage and slope stability before laying a single paver, because Upland’s split terrain between the old citrus-era valley floor and the graded foothill pads demands it. We install and repair Unilock’s full paver and wall systems as a buyer-direct contractor, not a manufacturer affiliate, so our recommendations are never tilted toward one product line. Call (855) 473-6535 for a free estimate on any Unilock patio, driveway, or retaining-wall project in Upland.
Why Upland Residents Choose Us for Unilock Service
Our crews know Unilock’s paver and wall systems the way a mechanic knows a specific engine family. Brussels Block, Beacon Hill, U-Cara, and Rivercrest each behave differently under load, under water, and under Upland’s August heat, and those behaviors dictate how we build the base, set the edge restraint, and grade the finished surface. Rick Sondermann, our owner, spent decades remodeling and building along the Southern California coast before bringing Unilock sales & service into our full-scope general contracting practice, and he still reviews every hardscape plan before we mobilize. That hands-on review is why our Upland jobs account for drainage and slope from day one, not as an afterthought when a wall starts leaning.
We’re an independent contractor, and that matters for how we handle Unilock work. We buy direct and install to the manufacturer’s specification, but we’re not obligated to push a Unilock product where a different wall block or drain solution fits the site better. On a hillside lot above Base Line Road, that honesty can save you from rebuilding a wall in three years. One team, full scope: we handle the pavers, the drainage, and the wall as a single coordinated project, not three separate bids.

Common Unilock Construction Problems We Solve in Upland
- Efflorescence bloom on Brussels Block and Beacon Hill patios. After Upland’s hot, dry summers and seasonal winter rains, mineral salts wick through the paver face and leave a white chalky film. This is usually a base-drainage and sealer issue, not a bad paver, and we diagnose it by looking at what’s underneath, not just what’s on top.
- Wall-face separation and cap loosening on U-Cara retaining walls. On the 91784 foothill lots, expansive soils shrink during dry months and pull the graded pad slightly away from the block, and the wall cap shows it first. We see this constantly above Base Line Road, and the fix is almost never gluing the cap back on. It’s re-compacting the pad and adding geogrid.
- Joint sand washout and edge restraint movement on flat-valley driveways. Santa Ana winds blast debris across driveways in Upland’s older neighborhoods, and when a monsoon-style storm follows, the water channels along the edges and scours the joint sand. The pavers hold, but the surface loosens, and edges migrate.
- Differential settlement on driveways near Euclid Avenue and Riverside Drive. Older citrus-era subgrades were never compacted or drained to modern paver standards, and when a paver driveway goes down over that legacy soil, ruts show up within two seasons. We rebuild the base, not the surface.
- Cap course drift and freeze-thaw on Rivercrest wall blocks. Rivercrest is a tumbled wall block, and on Upland’s clay-rich valley soil, the wall can shift slightly as the ground wets and dries through the year, leaving caps out of alignment. We reset and re-level them when the base is still sound.
Unilock Service in Upland: What Local Conditions Mean for Your Equipment
In the 91784 foothill ZIP above Base Line Road, Upland’s graded pads and expansive soils routinely open hairline cracks along patio perimeters and wall footings after dry-season shrinkage. That soil movement is Upland-specific: it comes from the alluvial fan geology at the foot of the San Gabriel Mountains, and it does not happen the same way down in the flat, irrigated valley around downtown or over the city line in Rancho Cucamonga or Claremont. For Unilock owners, it means a U-Cara retaining wall or a Brussels Block patio built to flat-valley specs will pull apart within a few years. So on every foothill project, we scope drainage, base depth, and wall geogrid into the plan before a single paver is laid. We test the subgrade, check where water flows during a winter rain, and build the base to resist the shrink-swell cycle. That’s the difference between a patio that lasts twenty years above the foothills and one that needs a tear-out in five.
Unilock Models & Products We Service in Upland
We build and repair the full Unilock system: Brussels Block, the tumbled traditional paver that anchors most Upland patios; Beacon Hill, the flagstone-look paver homeowners choose for a more natural surface; U-Cara, the multi-piece retaining and landscape wall system; and Rivercrest, the tumbled wall block for garden walls and seat walls. We use genuine Unilock pavers, U-Cara wall units, caps, and the manufacturer’s specified base and joint-sand system so walls and pavement perform as engineered. We don’t substitute thin aftermarket block on structural walls. Because we buy direct, we can typically source any Unilock line for Upland projects quickly, which keeps a repair or build from stalling while materials wander through a distributor’s queue.

FAQs – Unilock Construction in Upland
The white film is efflorescence, caused by mineral salts wicking up through the paver after Upland’s wet winters and hot summers. It means water is moving through your base and evaporating through the surface, and the fix is usually drainage improvement and a proper sealer, not replacing the pavers. Call (855) 473-6535 for a diagnosis and an exact quote, and we’ll tell you honestly if it’s cosmetic or structural.
Yes, and we do it regularly, but only after we scope the slope, check the expansive-soil behavior, and build the proper base and geogrid. A U-Cara wall on a graded foothill pad without that prep will separate from the slope within a few dry seasons, and we won’t build one that’s slated to fail.
They hold up well when the base and joint sand are installed to spec. The heat and wind themselves don’t damage quality pavers; what damages the installation is joint-sand blowout and water channeling when wind-driven debris clogs drainage. We build edge restraint and joint stabilization to account for exactly those Upland conditions.
A paver driveway flexes with Upland’s clay soils and can be lifted and re-leveled if a section settles. Concrete can’t. But a paver driveway needs a properly compacted subgrade, and many older Euclid-area lots have the original citrus-era soil underneath that was never prepared for modern loads. We’d check your subgrade before recommending either option.
We repair when the base and drainage are sound: we reset the courses, re-level the caps, and re-sand joint by joint. But when wall courses have separated because the subgrade failed, patching the face just hides the problem, and we rebuild the base instead. The call comes down to what’s underneath, not what’s visible.
