Unilock Construction in Fontana, CA | Polaris Contractors
Unilock pavers and retaining walls need a contractor who knows both the product line and the ground it’s going into. Polaris Contractors provides independent Unilock installation and repair across Fontana, from 92334 up through 92337. What sets our work here apart is straightforward: we know the soil conditions south of the 10 well enough to plan bases that won’t settle, and we know which Unilock lines hold their color under a Fontana August sun. Call us at (855) 473-6535 for a free estimate on your paver driveway, patio, or wall project. We serve the entire Fontana area, including the older mill-era neighborhoods and the newer north-side tracts.
Why Fontana Residents Choose Us for Unilock Service
We’ve been installing Unilock products long enough to know exactly how they behave in the Inland Empire. Rick Sondermann, our owner, has spent three decades building and renovating homes across Southern California, and he’s particular about hardscape because he’s seen too many patios sink or fade because someone saved a few dollars on base prep. We stock Unilock OEM pavers, wall units, and geogrid so repairs and new installations match in both color and structure. We use Unilock sales & service expertise born from real installation work, not just reading spec sheets. And because we’re a full-scope general contractor, we handle the whole project under one agreement: the excavation, the base, the pavers, the drainage, and the final finish. When a Fontana homeowner calls us about a sagging paver driveway on the south side, we already know what we’re likely to find when we dig.

Common Unilock Construction Problems We Solve in Fontana
Fontana’s climate and history create a specific set of Unilock failure patterns. Here’s what we see most often:
- Base failure and settlement from undocumented fill. South Fontana properties near the former Kaiser Steel mill often sit on buried slag, ash, and industrial debris. That material compacts unevenly over time and causes pavers to dip, crack, or shift. We over-excavate and rebuild the base with engineered fill before reinstalling the pavers.
- Efflorescence and color fade on lighter pavers. Brussels Block and similar lighter Unilock colors take a beating from Fontana’s intense UV exposure and smog. The white chalky residue and dulling are especially visible on driveways. We clean, recondition, and reseal pavers to bring color back, and we’ll tell you frankly if a paver is too far gone to save.
- Santa Ana wind-driven joint sand loss. Permeable paver systems lose joint sand during wind events. Once the sand goes, pavers shift and weeds move in. We re-sand with the correct polymeric materials and check the edge restraints, which are often the real culprit on Fontana patios.
- Retaining wall bulging in clay-heavy soils. Older Fontana neighborhoods have expansive clay that swells and shrinks with moisture. Without proper geogrid reinforcement, Unilock walls bulge and lean. We rebuild walls with the right grid depth and drainage behind the face.
- HOA-governed modifications in north Fontana. The master-planned tracts in 92336 and 92337 often require HOA approval for paver driveways and walls. We’ve worked with enough Fontana HOAs to know what documentation they expect, which keeps your project from stalling.
Unilock Service in Fontana: What Local Conditions Mean for Your Equipment
Here’s what we understand about Fontana that few other Fontana General Contractor teams will tell you before the shovel goes in the ground. The city’s construction identity is inseparable from the former Kaiser Steel mill site, and the legacy of that industrial era is literally underneath the surface in older south-side neighborhoods. When you excavate for a Unilock paver driveway or patio near the old mill footprint, you routinely hit buried steel slag, ash, and undocumented fill. That material does not compact uniformly. It causes differential settlement that shows up as sunken pavers and cracked edge restraints within a few seasons. In the newer north Fontana tracts, you’re working with graded, documented fill and you almost never see this. A contractor who gives you the same base spec for a 92335 job and a 92336 job is setting one of those projects up to fail. We don’t do that. We plan our over-excavation and engineered fill in south Fontana like the ground is going to move, because it already has. That’s the difference between a patio that stays flat for a decade and one that’s being torn out in three years.
Unilock Models & Products We Service in Fontana
We work with the full Unilock line, including Brussels Block, Beacon Hill, U-Cara wall systems, and Rialto Unilock service. We also field a lot of questions from homeowners comparing Unilock to Techo-Bloc, and we’ll walk you through the honest differences in color retention, texture, and price so you can make the call. For repairs, we use Unilock OEM pavers and wall units to guarantee a structural and visual match. For base materials like aggregate, we source from local suppliers who understand the Inland Empire’s soil needs. That hybrid approach gives you the manufacturer’s color and dimensional consistency where it matters, without overpaying for materials that don’t need a brand name. Most of what we need for a Fontana paver repair is available locally, which keeps turnaround times short.

FAQs – Unilock Construction in Fontana
Yes, but not without extra base work. We over-excavate through the debris layer, remove it, and rebuild the subgrade with engineered fill compacted in lifts. Skipping this step is why some south Fontana driveways sink within a few years. Call (855) 473-6535 for a free on-site look at what your lot needs.
Darker, textured pavers like Beacon Hill hold up better against UV fading and smog staining than lighter, smoother lines like Brussels Block, and our Glen Avon Unilock service covers similar climate conditions. That said, Brussels Block remains a popular Fontana choice for its classic look, and we seal it to slow the fade. We’ll show you samples side by side in full sun so you can see exactly what to expect after five Fontana summers.
Santa Anas don’t push walls over, but they do dry out the surrounding soil and strip moisture from joint sand. The real wind-related issue is with paver patios, where wind-driven sand loss loosens the surface. For walls, the bigger Fontana concern is clay soil expansion. Proper drainage and geogrid depth handle both.
Typically yes for a full driveway replacement, though patio installations often fall under different rules. HOA approval adds another layer in north Fontana tracts. We pull permits and handle HOA documentation as part of our scope, so you’re not stuck chasing paperwork. Call (855) 473-6535 and we’ll confirm what applies to your address.
North Fontana sits on graded, engineered fill from the 1990s-2000s master-planned developments, so it’s predictable and stable, unlike areas covered by our Pedley Unilock service. South Fontana, especially around 92335, has undocumented fill and buried industrial debris from the Kaiser Steel era. North-side jobs usually need standard base prep. South-side jobs need over-excavation and a rebuilt subgrade. That’s the honest difference.
