Unilock Construction in Ontario, CA | Polaris Contractors
We provide independent Unilock paver and wall installation, repair, and replacement across Ontario, CA. The one thing that separates our Unilock work here from a generic install is how we prep the base: Ontario’s expansive soils and old citrus-grove lots in the 91764 ZIP demand excavation and stabilization most crews skip. If you’re planning a paver driveway, patio, or retaining wall in Ontario, call Polaris Contractors at (855) 473-6535 for a free estimate.
Why Ontario Residents Choose Us for Unilock Service
Our crew has installed Unilock pavers and walls across the Inland Empire for over a decade, building a deep working knowledge of how their system performs in Ontario’s soil and climate. We know which Unilock lines hold their color under the Inland Empire sun and which base prep actually prevents settlement on expansive clay. We are an independent contractor, not authorized by Unilock, and we bring honest, field-tested expertise to every project.
Rick Sondermann, our owner, grew up in Corona del Mar and spent nearly three decades building and renovating homes along the Newport Beach coastline. He learned construction fundamentals at Saddleback College, and his father was a finish carpenter who believed in doing things once and doing them right. That philosophy drives how we approach every Unilock paver job in Ontario: do it right the first time, because the second time always costs more.
As a full-scope general contractor, we handle Unilock hardscaping as part of a larger project when needed, whether that’s a paver driveway tied to a new roof, a patio next to a kitchen remodel, or a full exterior refresh. One team, full scope. From the roof down to the pavers. See our Unilock sales & service overview or our Ontario service area page for details on coverage.

Common Unilock Construction Problems We Solve in Ontario
- Base failure and paver settlement in Ontario’s expansive soils. Rapid soil drying during the hot, dry summers causes clay to shrink and crack, which transfers directly to pavers when the base wasn’t excavated deep enough. We see this constantly in older Ontario neighborhoods where installs from the 1990s and early 2000s skipped proper compaction.
- Efflorescence and color fading on Brussels Block pavers. Ontario’s intense UV exposure and temperature swings put real stress on Unilock colorants, especially when the pavers were sealed with a cheap product. The chalky white efflorescence and washed-out browns we see on older Brussels Block driveways are almost always a sealant failure, not a paver failure.
- Chipping and cracking from heavy loads or improper compaction. In Ontario, where logistics traffic and delivery trucks are a daily reality, driveways take a beating. Pavers installed without adequate compaction of the sub-base and bedding layer crack and chip under heavier vehicles. This is common in neighborhoods near the warehouse corridors and along routes truckers use.
- Weed growth and joint erosion in Belgium-style blocks. When polymeric sand wasn’t installed correctly, or has been allowed to wash out, Ontario’s Santa Ana winds blow debris and weed seeds into open joints. Winter rains then flush the joints further. We regularly see Beacon Hill and Brussels Block patios with grass and weeds growing through seams that should be locked tight.
- Poor drainage and edge restraint failure. Ontario’s occasional winter rains, combined with improper drainage planning, cause edges to shift and pavers to drift. Without solid edge restraint and positive slope, a paver patio or driveway starts moving within a few seasons.
Unilock Service in Ontario: What Local Conditions Mean for Your Equipment
In Ontario’s 91764 ZIP, many postwar homes sit on former citrus groves. Old irrigation lines and organic debris remain in the soil, and that legacy shapes how Unilock paver installations have to be done here, in a way you won’t find in a new subdivision in Rancho Cucamonga or Chino Hills, though we also provide Unilock service in Chino. When we excavate for a paver driveway or patio in this part of Ontario, we regularly hit rotted irrigation pipe, decomposed root systems, and pockets of organic matter that compress over time. If you lay Unilock pavers over that without removing the debris and re-compacting the base, you’ll get settlement within two or three years, no matter how well the pavers themselves are installed. That’s why we over-excavate in 91764, haul out the organic material, and bring in structural fill. It adds a day or two to the job, but it’s the difference between a paver surface that lasts two decades and one that dips after two rainy seasons.
Unilock Models & Products We Service in Ontario
We work with Unilock’s full line of concrete pavers and wall systems, including the Brussels Block, Beacon Hill, Onyx Wall, and Elegance lines. Most Ontario jobs we take on involve these four product families. For repairs and extensions, we use Unilock’s OEM components, pavers, wall units, and their proprietary polymeric sand, for color and dimensional consistency. For base materials and geotextiles, we source quality aftermarket products chosen specifically for Ontario’s clay and former-ag land conditions. We’ll always give you an honest repair-versus-replace assessment: if the base is failing, replacing the surface alone is a waste of money. We stock common Unilock paver profiles and matching polymeric sand so Unilock repair in Montclair and repairs across Ontario can move quickly.

FAQs – Unilock Construction in Ontario
No, Unilock pavers won’t crack from heat alone. The paver itself is designed for temperature swings. Cracking happens when the base underneath fails, usually from inadequate compaction or expanding clay. We address that at the source with proper excavation and soil stabilization. Call (855) 473-6535 if you’re seeing hairline cracks spread across a paver surface.
We remove them. Old citrus-grove irrigation lines in Ontario’s 91764 ZIP are usually galvanized steel or clay tile, and they’re almost always abandoned. When we excavate for a new Unilock paver driveway, we identify any remaining lines, cap them if they’re live, and haul out the debris. Leaving them in place creates voids that lead to settlement later.
Brussels Block is our default recommendation for Ontario driveways that handle delivery traffic. It’s thick, it interlocks well, and it holds up under repeated loading if the base is compacted correctly. The key isn’t just the paver, it’s the preparation. A properly compacted base under Brussels Block will handle daily delivery trucks without chipping. Call (855) 473-6535 and we’ll assess your specific driveway.
It depends on the scope. A paver patio that doesn’t change drainage or coverage usually doesn’t need a permit in Ontario, but a new driveway or a significant replacement often does, especially if it affects the public right-of-way or stormwater flow. We handle the permitting questions during our estimate walk. Call (855) 473-6535 and we’ll tell you what applies to your property.
Yes, in most cases. We use Unilock’s OEM pavers and their proprietary polymeric sand, and we match the existing product line and color as closely as the lot variations allow. If your pavers have been in place for a decade or more, there may be some color difference between old and new, but we’ll work with you to minimize it. Call (855) 473-6535 for a free repair assessment.
