Unilock Construction in Upland, CA | Alder Contractors
Unilock paver and wall installation in Upland runs $3,500 – $18,000 depending on scope, and we’re the independent contractor that handles everything from paver driveways to retaining walls across 91784, 91785, and 91786. What sets our Unilock work apart here is that we build for the city’s two-speed reality: fire-zone foothill lots and historic-district downtown streets, sometimes in the same week. Call (833) 467-7020 for a free estimate, and we’ll walk your property with you before we quote anything.
Why Upland Residents Choose Us for Unilock Service
Unilock pavers and walls show up on driveways, patios, and retaining walls all over Upland, from the 1950s tract homes in the 91786 core to the larger foothill properties climbing toward the San Gabriels in 91784. We’ve installed Unilock products on dozens of Inland Empire properties, from Rancho Cucamonga Unilock service calls to Upland foothill jobs, and we know which lines hold up to Santa Ana winds and which base treatments stop clay soil from heaving. Nelson Ibarra, our owner, grew up in the Willow Avenue corridor of Rialto and has spent nearly three decades working the homes of the Inland Empire. He’ll tell you the same thing we tell every Upland homeowner: the paver is only as good as what’s underneath it. We use Unilock OEM pavers and wall units for replacements and additions so color and texture match, and we specify quality aftermarket polymeric sands and base aggregates where they meet or exceed spec. If a section is failing because of base or drainage problems, we rebuild it rather than patching pavers that will shift again. That’s the difference between a surface that lasts and one that needs a callback.

Common Unilock Construction Problems We Solve in Upland
- Efflorescence on Brussels Block and Copthorne pavers. Upland’s winter rains, followed by hot dry spells, pull mineral salts to the surface of pavers when the base wasn’t choked off properly at install. We see this on older Upland driveways and patios where the original installer skipped the aggregate choke layer. We clean the surface and address the base issue, not just the white haze.
- Edge spalling and chipping on driveway pavers. Where de-icing salts have been used, or where pavers weren’t compacted to manufacturer spec, edges start to chip. Upland’s temperature swings between cold foothill nights and hot valley days make this worse. We replace damaged units with matching Unilock OEM pavers and correct the compaction issue.
- Weep-hole staining and color fade on retaining walls. Foothill lots in 91784 sit on clay soils that hold water behind walls. When drainage wasn’t installed correctly, you get staining at weep holes and fading across the wall face. We rebuild with proper drainage aggregate and filter fabric so water exits where it’s meant to.
- Joint sand loss and paver shifting after Santa Ana wind events. Upland’s wind corridor strips joint sand fast when polymeric sand wasn’t installed to manufacturer depth. Pavers start to shift, and the surface loses its interlock. We re-sweep, re-activate, or rebuild with proper depth and edge restraint.
- Base failure from clay soil expansion. Upland’s native clay expands and contracts with moisture, which heaves a poor base. We’ll see centered depressions and cracked edges on driveways that looked fine for a few years, then failed all at once. A geotextile separator and proper aggregate depth fixes the root cause.
Unilock Service in Upland: What Local Conditions Mean for Your Equipment
Here’s the thing about Upland that affects every Unilock project: the 91784 foothill properties sit in a Santa Ana wind corridor and CalFire brush-clearance zone, so installations there must use noncombustible edge restraints and base materials that won’t wash out during the first post-fire-season rain. Meanwhile, downtown jobs near Euclid Avenue often trigger historic-district review, which means pavers that complement historic streetscapes without mimicking them. Two very different permitting and detailing realities within the same city. On a paver driveway replacement in the 91784 foothill area above the San Gabriel wash, we pulled out a failing asphalt drive and installed Unilock Brussels Block over a compacted aggregate base with a geotextile separator and concrete edge restraint. The original drive had heaved from clay soil and wind-driven debris. We regraded for positive drainage away from the garage, and the homeowner now has a surface that handles both brush-clearance inspections and daily parking without rutting. That’s the kind of site-specific work Upland demands, and it’s what we plan for from the first site visit.
Unilock Models & Products We Service in Upland
We install and service the Unilock lines Upland homeowners actually use. Brussels Block for driveways and patios; Beacon Hill for a tumbled, aged look on walkways and pool decks; Copthorne for a larger-format paver that works well on contemporary foothill builds; and Estate Wall for retaining walls and seat walls. For replacements and additions, we order Unilock OEM units to match your existing color and texture; we don’t sub in some off-brand paver that’ll look wrong the day it goes in. Polymeric sands, base aggregates, and edge restraints are sourced from quality aftermarket suppliers where they meet or exceed Unilock’s installation spec. We stock common base and joint materials for fast turnaround on Upland projects, and we order pavers direct by line and color so we’re not waiting on a local yard to guess what you need. We’re an independent contractor, not a dealer, so we specify what your site actually needs. See our full Unilock sales & service page for more on how we approach the brand.

FAQs – Unilock Construction in Upland
Yes, but only with the right base and edge treatment. Sloped lots in 91784 need a geotextile separator, a properly compacted aggregate base, concrete edge restraint, and drainage that directs water away from the slope face. We install Unilock pavers on foothill slopes regularly, and the key is matching the base detail to the grade and soil. Skip the edge restraint or skimp on base depth, and the first heavy rain will move pavers downhill. Call (833) 467-7020 if you want us to take a look at your slope; the estimate is free.
Projects near the Euclid Avenue historic corridor may need to go through design review, which means the city staff wants to see that new hardscape is compatible with the historic streetscape, not identical to it. We’ve worked with Upland homeowners on pavers that read as appropriate for older homes without creating a period-pastiche that looks forced, and we bring that same approach to Unilock repair in Montclair when historic compatibility matters there too. The process is navigable, but you want a contractor who knows what triggers review and what doesn’t. We’ll tell you during the estimate if your project is likely to need it.
Brussels Block is the workhorse for Upland driveways. It’s a tumbled, multi-size paver with enough surface irregularity to hide the fine dust that Santa Ana winds blow across the valley, and it handles vehicle loads well over a proper base. Copthorne also holds up on larger driveways, especially on newer foothill builds with more contemporary lines. The paver choice matters less than the base preparation, honestly; in Upland’s clay soil, the base is what keeps a driveway from heaving. We’ll spec the line that fits your property and your budget.
It depends on the wall height and where the project sits. Retaining walls over a certain height generally require a permit and possibly engineering review, and patio work in the foothill fire zones may be subject to brush-clearance and noncombustible-edge requirements. We handle the permitting conversation as part of our scope; our general contractor license covers hardscape and exterior work, and we’ve pulled permits in Upland for walls, driveways, and full exterior renovations. We also manage permits for San Antonio Heights Unilock service projects in their specific fire-zone requirements. Call (833) 467-7020 and we’ll tell you exactly what your project needs.
Start with a good polymeric sand installation at the correct depth, which keeps joint material from blowing out and pavers from shifting. After that, it’s about seasonal maintenance: sweep debris off the surface before it gets ground in, rinse pavers with water rather than pressure-washing at full blast, and address any low spots where dust collects. Pavers in Upland’s wind corridor sometimes need joint sand touched up after a particularly rough Santa Ana season. If you’re seeing sand loss or shifting, call us before it gets worse; a small re-sanding is cheaper than a rebuild.
