Unilock Construction in Upland, CA | Elmwood Contractors
We provide independent Unilock paver, driveway, and retaining wall construction across all three Upland ZIP codes: 91784, 91785, and 91786, plus Unilock service in Claremont. What sets our Unilock work apart here is that we build for Upland’s two very different construction regimes: engineered foothill grades under wildland-urban interface rules up the hill, and flatland tract driveways on expansive soils down below. One contractor, every trade, interior to exterior. Call (866) 253-8554 to schedule your free estimate and get the right Unilock product specified for your exact lot.
Why Upland Residents Choose Us for Unilock Service
We’ve installed Unilock pavers and walls across Upland’s sloped foothill lots and flatland drives, so we know which profiles, base depths, and joint sands actually hold up under Santa Ana winds and expansive soils. Brussels Block on a flat 91786 driveway behaves differently than Brussels Block on a 91784 grade break. That distinction matters, and it’s exactly the kind of thing Nolan Shepherd has spent two decades learning. He grew up in Fullerton’s Sunny Hills neighborhood, where half the houses on his street were built in the late ’60s, and he knew by his teenage years which ones were going to have foundation problems—insight that now shapes our Unilock repair in Montclair too. That early read on soil and slope now translates directly into how we prep a Unilock base in Upland. We’re an independent contractor, not a Unilock dealer or authorized installer, which means our recommendations are driven by what performs on your lot, not by what a manufacturer incentive program tells us to push. We name the brands going into your home before the contract is signed, and for hardscape that means genuine Unilock units matched with aftermarket base aggregates and polymeric sands we’ve tested in Southern California’s heat cycles.

Common Unilock Construction Problems We Solve in Upland
- Efflorescence bloom on Brussels Block and Beacon Hill pavers. Upland’s hot-dry summers pull moisture up through the paver body, and when the base drainage is inadequate, salts precipitate on the surface as that white, chalky film. We fix the drainage first, then address the bloom.
- Edge spalling and paver migration on sloped 91784 driveways. Where the base wasn’t engineered for grade, Santa Ana wind-driven runoff scours the edges and every tire pass works the pavers loose. We rebuild with a geogrid-reinforced base and edge restraints rated for slope.
- Retaining wall bulging on Seneca block walls. Upland’s expansive soils push on walls that were installed without proper geogrid layering and crushed-stone drainage behind the block. A surface patch won’t hold; we reset the wall with the drainage and reinforcement the original job skipped.
- Joint sand loss and rutting on 91786 driveway aprons. The post-war slab driveways in Upland’s flatlands meet new paver transitions at the apron, and that junction is where water pools and base washes out. We cut out the failed apron and re-bed it with a stabilized base, then use a polymeric sand formulated for vehicle loading.
- Heaved driveways from expansive soil movement. The same clay that cracks stucco in Upland’s dry climate also lifts paver driveways when the base isn’t isolated from the subgrade. We install a geotextile separation layer and adjust the base depth to the soil conditions on your particular street, not a generic spec.
Unilock Service in Upland: What Local Conditions Mean for Your Equipment
Above roughly the 2100-foot contour in the foothill edges of 91784, a paver hardscape is treated as a wildland-urban interface (WUI) exterior assembly. That’s a spec that never comes up on 91786 flatland driveways. Ember-resistant detailing and noncombustible edging matter as much as the pavers themselves, because the building department will ask about them, and because an ember landing in a paver joint filled with dry organic debris is a fire pathway. On a sloped Euclid Avenue-adjacent lot in 91784, our crew tore out a heaved 1990s driveway and rebuilt it with Unilock Brussels Block on a geogrid-reinforced base with a channel drain to shed Santa Ana runoff. We re-set the Seneca wall at the grade break with proper drainage behind the block. That drive has stayed flat through two summers. When you live in the foothill edges of Upland, your hardscape is part of your home’s fire envelope, and we build it that way from the first compacted lift.
Unilock Models & Products We Service in Upland
We work with the Unilock lines most common in Upland: Brussels Block, the workhorse for driveway and patio surfaces; Beacon Hill, the tumbled profile that shows up on a lot of Upland’s older custom homes; Tribeca Cobble, popular for walkways and pool surrounds on the flatland lots; and Seneca block for retaining walls on grade breaks. For repairs, we source genuine Unilock units so color and dimensional match stays true across the repair line, whether the job is in Upland or calls for our Rancho Cucamonga Unilock service. For base aggregates and joint sands, we use aftermarket products where they outperform, because a repair is only as good as what’s underneath it. We’ll tell you honestly when a failing wall or drive needs reconstruction rather than a surface patch. The right material in the right place. Everything else is just catching up to that decision.

AfterUnilock Service Pricing in Upland
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
What drives the number is your lot. A flatland 91786 driveway replacement with standard base depth lands on the lower end. A sloped 91784 job with geogrid reinforcement, WUI-compliant edging, and channel drainage lands higher, because the engineering hours and material quantities are simply different. Every free estimate includes a written line-item quote that names the Unilock product line, the base spec, and the joint sand going into the job. Call (866) 253-8554 to schedule yours.

FAQs – Unilock Construction in Upland
Yes. Sloped lots in Upland’s foothill ZIP require a deeper, geogrid-reinforced base with drainage designed for grade and Santa Ana runoff, while 91786 flatland driveways typically use a standard compacted aggregate base over geotextile fabric. The paver itself is the same; what’s underneath it is not. Call (866) 253-8554 for a site-specific base recommendation.
We source genuine Unilock Brussels Block for repair so the color and dimensional match stays true across the joint line. Keep in mind that older pavers have UV-aged, so a fresh unit will look slightly brighter at first, then blend as it weathers. If the remaining base is also failing, we’ll tell you that a partial patch won’t hold, and quote a full replacement of the affected section.
If your property sits above roughly the 2100-foot contour, yes. The hardscape is reviewed as part of the wildland-urban interface assembly, which means ember-resistant detailing, noncombustible edging, and defensible-space compatibility. We coordinate that spec during the estimate so there are no surprises at plan check.
Upland’s expansive soils press against Seneca block walls that were installed without proper geogrid reinforcement and crushed-stone drainage behind the block. The wall face starts to lean or bulge as the soil expands with moisture. A surface patch won’t correct the failure; the wall needs to be reset with correct drainage and reinforcement. Call (866) 253-8554 and we’ll assess what’s behind your wall.
Efflorescence is salts migrating through the paver body when water moves upward through the base. In Upland’s hot-dry cycles, that happens when base drainage is inadequate and water sits under the pavers. The fix is to correct the drainage, then clean the bloom. If we’re installing new, we spec the base so it never has standing water in the first place. Call (866) 253-8554 for an assessment.
