Unilock Construction in Ontario, CA | Workshop Contractors
We install and repair Unilock paver patios, driveways, and retaining wall systems throughout Ontario, CA. We’re an independent crew, not a dealer, which means we recommend the Unilock product that actually fits your lot’s soil and sun exposure, not the line someone’s trying to move that month. The thing that separates our Unilock work in Ontario from generic installs is how we handle the expansive clay under the older south-side neighborhoods. Call (844) 384-3361 for a free estimate on any Unilock project, from a new paver driveway to releveling a settled Brussels Block patio.
Why Ontario Residents Choose Us for Unilock Service
We’ve been taking apart and rebuilding hardscape in the Inland Valley long enough to know that a Unilock patio in Ontario doesn’t behave like one in Claremont or Upland. The soil is different. The drainage is different. The way the Santa Anas push sand out of joints is different. Noel Figueroa grew up in the Vineyard neighborhood and learned the fundamentals at Chaffey College, where the construction technology program put him on local job sites early. He has spent the years since working across the Inland Empire, including Unilock service in Chino and around Ontario, where he is known for the kind of finish work that holds up under a second look, pavers that line up, edges that stay put, and joints that don’t pump sand after the first wind season. When we quote a Unilock job here, we quote it for Ontario’s soil and Ontario’s climate, not a generic spec sheet.
As Unilock sales & service specialists, we handle everything from material selection to final compaction. We source genuine Unilock units for repairs so color and dimension match existing courses, and we use aftermarket polymeric sand and edge restraints where they outperform the factory option. You get one crew responsible for the whole job.

Common Unilock Construction Problems We Solve in Ontario
- Joint sand loss and edge migration on Brussels Block driveways. Santa Ana wind seasons in Ontario pull the fines right out of joints when the edge restraint is short. We see this on slab-on-grade lots throughout the older neighborhoods south of Holt, where driveway edges sit close to the house slab and there isn’t enough room for a proper restraint. We relevel, reset the edge, and switch to a polymeric sand that holds in wind, so the sand doesn’t pump out every fall.
- Efflorescence blooming on gray-toned Unilock pavers. The expansive clay in south Ontario holds moisture under the bedding layer, and that moisture wicks up through gray Brussels Block and Beacon Hill units, leaving white hazy patches. We treat the surface and adjust the base drainage, but the real fix is in the subgrade prep most installers skip entirely.
- Settling and lippage on Beacon Hill and Umbriano walkway pavers. Walkways laid over a thin compacted base on post-war lots near downtown almost always develop lips between courses. The clay expands and contracts, and without a thick enough base, every paver moves independently. We pull the affected section, recompact a proper base, and relock the same units where they’re still sound.
- Uni-Stone retaining wall face spalling and cap cracking. Walls backfilled without drainage in Ontario’s hardpan clay soils trap water behind the face. In summer heat, that trapped water and the expanding clay create pressure that spalls the block face and cracks caps. We add clear drainage rock and a proper drain line, then rebuild the affected courses.
- Slab-edge settling where paver patios meet house footings. Many post-war Ontario homes have shallow footings that shift on clay, and patio pavers laid right up against the slab move with them. We add positive drainage away from the slab and compact the base deeper than the original install, so water isn’t sitting against the house and the pavers stop shifting.
Unilock Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario’s south-side post-war homes sit on slab-on-grade with shallow footings over expansive clay, and that single fact drives most of the Unilock work we do here. Paver driveways and patios need a deeper, more aggressively compacted base and positive drainage away from the slab, something we rarely see called for in the foothill cities like San Antonio Heights. On a 1950s slab-on-grade home south of Holt Boulevard, our crew pulled up a settled Brussels Block driveway whose edge had heaved on the clay and re-laid it over a deeper compacted base with proper edge restraint and polymeric sand. The sound units went back in so the color matched. The customer got a flat, positively drained driveway that won’t pump sand in the next Santa Ana season.
This is what we mean when we say Ontario Unilock knowledge has to be built here, not imported. A contractor from Rancho Cucamonga who only works decomposed granite slopes will quote a base depth that fails on our clay in two seasons. This is the one thing a generic Unilock page can’t tell you because it doesn’t hold the shovel here. For the full picture of the neighborhoods we work, see our Ontario service area page.
Unilock Models & Products We Service in Ontario
We install and repair the full Unilock residential product range, including Brussels Block and the Brussels Dimensional System, Beacon Hill smooth pavers, the Uni-Stone retaining wall system, and large-format Elegance and Umbriano slabs. We source genuine Unilock units for spot repairs so the color and dimensional profile match the existing courses. Where the factory parts fall short, like joint sand and edge restraint, we stock aftermarket polymeric options that hold up better in Ontario’s wind and clay. That means faster local turnaround because we’re not waiting on a dealer delivery.

AfterUnilock Service Pricing in Ontario
Unilock paver and wall costs in Ontario vary based on the condition of your subgrade, how much excavation and recompaction the clay demands, and which product line you choose.
| Unilock Service | Typical Ontario Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
Most of the variance comes down to your lot. Deeper clay means more base, more compaction, and more disposal. A free estimate from us includes an on-site look at the subgrade and a written line-item quote, not a hand-wavy number over the phone. Call (844) 384-3361 to get specific numbers for your Ontario property.

FAQs – Unilock Construction in Ontario
Yes, we install permeable Unilock paver systems. They work well in Ontario where the clay subgrade holds water, because the open joints let water move down into the base instead of pooling on the surface and finding the house slab. We recommend them for patio areas especially, where the grade is relatively flat and surface drainage is a problem most conventional installs never solve. Call (844) 384-3361 to talk through whether a permeable system makes sense for your specific lot.
No. We’re an independent crew that installs and repairs Unilock products throughout Ontario. We’re not authorized, sponsored, or warrantied by Unilock, and that independence is what lets us tell you when a different product or a different base design makes more sense than what a dealer would default to. We can recommend the right system for your site instead of the one someone’s inventory says to push.
Most spot repairs and releveling jobs on Unilock patios and walkways finish in one to three working days. Full driveway rebuilds over a deeper compacted base typically run one to two weeks, depending on excavation and how much disposal the clay demands. The schedule starts with a free site visit. Call (844) 384-3361 and we’ll tell you a realistic window for your specific project.
We handle Brussels Block and the Brussels Dimensional System, Beacon Hill smooth pavers, Uni-Stone retaining wall systems, and the large-format Elegance and Umbriano slab lines. We carry genuine Unilock units for repairs on these lines, matched for color and dimension, and we keep aftermarket edge restraints and polymeric sand in stock for the Ontario climate. If you have an older Unilock line and you’re not sure what it is, send a photo and we’ll identify it.
Releveling and resetting a settled Unilock driveway in Ontario typically falls in the $5,000 to $14,000 range when we’re replacing the failed base, not just spot lifting. The final number depends on how deep the clay compaction problem goes and how many of the original units are still sound enough to reuse. Reusing sound units keeps the color matched and the cost down. Call (844) 384-3361 for a written quote, free.
