Unilock Construction in Upland, CA | Workshop Contractors
We install, repair, and rebuild Unilock paver driveways, patios, and retaining walls across Upland. As an independent general contractor, not a manufacturer affiliate, we bring years of field experience with Unilock products into every job. The thing that sets our work apart here is simple: we know how these pavers and walls behave on Upland’s expansive clay and steep foothill slopes, and we build accordingly. Call (844) 384-3361 for an estimate grounded in local soil reality, not a brochure.
We’re Workshop Contractors, led by Noel Figueroa, and we’ve been working the Inland Empire long enough to know that a paver installation is only as good as the base under it and the drainage around it. Unilock makes excellent products. The failure we see in Upland almost never comes from the pavers themselves; it comes from what was under them, or what wasn’t, when the original install happened. That’s where our work starts. For broader project context, you can explore our Unilock sales & service page, and for everything else we cover, see our Upland service area details.
Why Upland Residents Choose Us for Unilock Service
Noel Figueroa grew up in the Vineyard neighborhood of Ontario, where he learned from the same generation of tradesmen who built half the houses on his street. He trained at Chaffey College, where the construction technology program put him on real job sites before he could rent a truck. That background matters when you’re dealing with a paver driveway on a Upland hillside lot that’s shifted after two rainy seasons.
We stock genuine Unilock replacement pavers and wall blocks for matching existing installations, and we also keep high-quality aftermarket polymeric sand and base material that, frankly, outperforms OEM in our clay soils. When a client on a foothill street in 91784 called after winter storms because their Brussels Block driveway had heaved and settled near the garage, we removed the affected pavers, excavated to stable soil, re-compacted the base in lifts, installed a perforated drain pipe and gravel behind the bulging retaining wall, and re-laid everything with fresh polymeric sand. The driveway is level now and the wall is stable with positive drainage away from the house. That’s the kind of correction we do in Upland all the time.
One contractor, every trade. From the roof down to the pavers, we handle it. And because we’re a licensed general contractor, not a specialty subcontractor, the person managing your drainage improvements and the person laying your Unilock pavers is the same person reporting to you.

Common Unilock Construction Problems We Solve in Upland
- Base settlement and sinking pavers on sloped driveways in 91784. Expansive clay expands when wet and contracts when dry. If the original base wasn’t compacted in lifts, or if no geotextile fabric was used between native soil and aggregate, the pavers shift. We excavate, correct the base, and re-lay the same pavers when they’re still sound.
- Efflorescence and salt deposits on Brussels Block pavers after winter rains. Efflorescence is a mineral salt deposit that gets pulled to the surface as water moves through the paver. In Upland, it’s most common where drainage is poor and water pools against the house. We identify the water path first, fix it, then address the paver surface.
- Retaining wall block movement and bulging from hydrostatic pressure. After heavy rain on foothill lots, water builds up behind walls built without drainage. That pressure pushes the wall outward. We regrade the swale, add a French drain and gravel behind the wall, and rebuild the affected section with matched Unilock block.
- Surface spalling and color fading on older Elegance pavers. Intense summer sun and Santa Ana wind events accelerate surface wear on pavers that weren’t sealed, or were sealed with the wrong product. We evaluate whether the paver can be salvaged with a proper cleaning and sealant, or whether selective replacement makes more sense.
- Patio edge failure where pavers meet the house. In Upland’s winter storm cycles, runoff from roofs without gutters undermines the edge restraint on paver patios, causing pavers to creep away from the foundation. We correct the drainage first, then re-lay with a properly embedded edge restraint.
Unilock Service in Upland: What Local Conditions Mean for Equipment
Here’s something Upland-specific that matters a lot: homes on the north-side streets that back up to the San Gabriel foothills in 91784 frequently need retaining walls and swales regraded after heavy rain seasons. This is a pattern we see repeat in the canyon-adjacent pockets every single year, and it’s not something contractors in Ontario or Chino deal with on the same scale. The original construction on these foothill lots often predates modern drainage detailing. Many Unilock walls and paver patios were built without engineered drainage behind them, so when rain hits, expansive clay holds water against the wall face. Hydrostatic pressure builds. The wall moves. The pavers above shift with it.
For Unilock owners in Upland, this means a paver problem is rarely just a paver problem. It’s a drainage and slope-stability problem that happens to show up in the pavers. We routinely regrade swales, add French drains behind walls, and install perforated pipe before re-laying a single paver. That’s a fix that’s rarely needed in flatter inland cities, and it’s why our Upland service looks different from our work elsewhere in the Inland Empire.
Noel likes to say: build it right the first time. The second time costs twice as much and nobody’s happy about it. That applies double on a foothill lot in Upland.

FAQs – Unilock Construction in Upland
In Upland, shifting pavers on driveways in 91784 and other foothill ZIP codes are almost always caused by expansive clay under the base. When the clay saturates in winter, it swells; when it dries in summer, it contracts, and any pavers installed without proper compaction or geotextile fabric between native soil and aggregate will move. The fix is excavating to stable soil, re-compacting in lifts, installing fabric, and re-laying the pavers, not just dumping more sand on top. Call (844) 384-3361 and we’ll assess the base under your driveway.
Yes. When we repair a Brussels Block patio or walkway, we source genuine Unilock replacement pavers when available to match the existing installation in color and size. Unilock paver lines have been produced in different manufacturing runs over the years, and if we can’t get an exact match, we’ll tell you that before we start, and we’ll work with you on a blend or a replacement section rather than making a mismatched patch that looks worse than the original problem.
Efflorescence is mineral salts surfacing through the paver, and in Upland it’s most common on patios where water pools against the house after winter rains. The way to prevent it is not a coating; it’s drainage. We correct the grading so water moves away from the patio, we make sure the base drains properly, and then we clean the pavers with a product rated for efflorescence removal. If we re-lay a section, we use polymeric sand that resists water migration. For an exact plan for your patio, call (844) 384-3361.
A paver driveway in Upland typically runs $7,000 – $18,000 depending on square footage, base condition, slope, access, and whether drainage correction is needed. Foothill lots in 91784 often run toward the higher end because of the base correction and drainage work that flatter-lot driveways don’t need. Replacement of an existing driveway runs $5,000 – $14,000. The only way to get an exact number is a site visit and a written scope. Estimates are free; call (844) 384-3361 to schedule one.
Yes. Leaning or bulging Unilock retaining walls in Upland foothill areas are nearly always the result of hydrostatic pressure from water trapped behind the wall in clay soil. We excavate behind the affected section, install perforated drain pipe and gravel, regrade the swale above the wall, and rebuild the block with proper geogrid reinforcement. We use genuine Unilock wall block when available to match the existing wall. Call (844) 384-3361 for an assessment before the next rain season.
