Unilock Construction in Ontario, CA | Hampton Contractors
We provide our General Contractor in Ontario for independent Unilock construction service across Ontario, CA, from paver driveways and patios to retaining wall work in the older core and the newer subdivision rings. The single thing that makes our Unilock work different here is how we prepare the base: Ontario’s slab-on-grade tract homes sit on shrink-swell clay that moves, and a paver driveway only survives if we over-excavate and re-compact beneath it. We install genuine Unilock units with manufacturer-specified edge restraint and polymeric sand. Call (833) 467-4075 for a free estimate on any Unilock project in Ontario.
Why Ontario Residents Choose Us for Unilock Service
We work with Unilock product lines day in and day out across Ontario’s 91764, 91798, 91758, and 91761 ZIP codes. Brent Calloway grew up in the High Desert and has been on job sites since he was eighteen, and that background shapes how we approach every paver field we set. We know the difference between a driveway that photographs well and one that still looks tight after five summers of 100-degree heat and Santa Ana wind. As an independent contractor, we’re not manufacturer-affiliated or authorized. That means we can tell a homeowner in Ontario straight when a full re-lay makes sense and when lifting, re-grading, and re-setting the existing field gets the same result for less money. We carry the full Unilock sales & service range through our supplier relationships, and we spec OEM units so color and dimension line up with the manufacturer’s warranty. Good work doesn’t need a disclaimer.

Common Unilock Construction Problems We Solve in Ontario
- Efflorescence and salt bloom on the paver face. Ontario’s inland summers bake moisture up through unsealed units, and that mineral residue shows up as a white haze within the first hot season. We clean the surface, address drainage, and seal when the paver is dry enough to hold a sealer properly.
- Joint sand blow-out and paver edge creep. Santa Ana winds scour open joints and push against any perimeter that isn’t mechanically restrained. In Ontario, we set edge restraint deeper than a coastal install would require. Where sand is already gone, we re-sweep manufacturer-specified polymeric sand and reset the edge before it fails.
- Base settlement and paver rocking on shrink-swell clay. The core neighborhoods in 91761, 91762, and 91764 sit on slab-on-grade foundations over clay that cracks and heaves. When a paver driveway rocks or dips, the problem is almost never the paver. It’s the base under it. We lift, over-excavate, and re-compact with aggregate before re-setting the field.
- Hairline cracks and spalled edges where pavers were set tight against existing slab flatwork. Ontario’s older concrete patios and walkways shift with the clay, and pavers butted against that movement crack at the contact line. We cut in a proper joint and mechanically isolate the paver field from the slab so the failure stops.
- Drainage that sends water under the paver field. Ontario’s hot, dry weather makes homeowners forget how hard a winter storm can hit. We re-grade the sub-base slope and add drainage so water moves away from the field, not through it. A paver driveway in Ontario fails from below, never from the surface.
Unilock Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario’s older core tracts were built slab-on-grade over shrink-swell clay that cracks and heaves under inland heat. That’s not a footnote; it’s the whole story for a paver driveway in 91761, 91762, or 91764. A Unilock driveway here lives or dies on how far we over-excavate and re-compact the base beneath the existing slab edge. Almost every core-neighborhood quote we do in Ontario reveals the same problem: the original flatwork was poured on a thin sand base over moving clay, and the slab edge has already cracked. A homeowner who wants a “cheap” paver overlay on top of that is buying a failure. The overlay looks fine through March, then the first hot summer cooks the ground, the clay shrinks, the base shifts, and the pavers rock. We won’t sell that job. We over-excavate about eight inches, lay geotextile, install a compacted aggregate base, and only then set the Unilock field with edge restraint and polymeric sand. The paver is the finished surface; the base is the product. In Ontario, the base is the hard part.
Unilock Models & Products We Service in Ontario
We install and service the full range of Unilock hardscaping products across Ontario, including Brussel Dimensional Stone with its classic cobble look, Cambridge Pavingstones with ArmorTec for a harder surface that resists salt and wear, Beacon Hill Flagstone for walkways and pool decks, and the Lineo and other retaining-wall block systems. When a field needs new units to match an existing install, we source genuine Unilock rather than aftermarket imitations, because color batch and dimensional tolerance matter when you’re weaving new pavers into an old field. We stock common polymeric sand and edge restraint locally for fast turnaround on Ontario jobs. Partial rebuilds are routine: if one section has settled or cracked, we lift only that area, re-grade the base, and re-set with matching units. A full tear-out is rarely the first option.

AfterUnilock Service Pricing in Ontario
What drives the cost of Unilock work in Ontario is the base. A straight sand-set overlay in a core-neighborhood yard might look cheap on paper, but it fails inside the first hot season. Our pricing reflects the excavation, geotextile, aggregate, and compaction that actually make a paver field last here.
| Service | Price Range (Ontario) |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Driveway Sealing | $250 – $700 |
Every estimate includes a written line-item quote, not a handshake number. We walk the site, probe the base where we suspect clay movement, and tell you straight whether a partial rebuild or full replacement is the right call. Call (833) 467-4075 to schedule your free estimate in Ontario.

FAQs – Unilock Construction in Ontario
No, not as a direct overlay. In Ontario’s older core, the concrete has usually cracked because the clay under it moved, and pavers set over that same moving slab will rock and separate within the first hot season. We remove the concrete, over-excavate the base, re-compact with aggregate, and set the Unilock field properly. Call (833) 467-4075 for an exact quote on your driveway.
They will if the perimeter isn’t mechanically restrained and the joints aren’t set with a manufacturer-specified polymeric sand. In Ontario’s wind corridor, we set edge restraint deeper than standard and make sure the sand has a chance to cure before the first wind event hits. If your existing joints are scouring, call us at (833) 467-4075 and we’ll re-sweep and re-set before the field creeps.
Cambridge Pavingstones with ArmorTec is the line we recommend for west-facing patios in Ontario and Rancho Cucamonga Unilock service areas. ArmorTec is a hardened surface treatment that resists surface wear and salt, and it stands up to direct afternoon heat better than softer concrete units. That said, the paver line matters less than the base and drainage. Call (833) 467-4075 and we’ll walk your patio and spec the right product for your exposure.
Yes. In Ontario, the apron section is often the first to fail because it sits right where the original slab edge meets the garage floor, and that’s exactly where clay movement shows up. We lift the settled section, re-grade and re-compact the base, and re-set matching Unilock units with edge restraint and polymeric sand. A partial rebuild is usually the right answer. Call (833) 467-4075 for a free on-site assessment.
Yes, and we do this regularly in Ontario’s core ZIPs and San Antonio Heights Unilock service areas. The key is a proper isolation joint so the pavers don’t butt directly against the shifting slab. We cut in a clean separation, set the paver field on its own compacted base, and tie the two surfaces together visually while keeping their structural movement independent. For a quote on your patio, call (833) 467-4075.
