Unilock Construction in Rialto, CA | Timberline Contractors
We install and repair Unilock segmental paving, retaining walls, and permeable systems across Rialto’s 92376 and 92377 ZIP codes, and also offer Unilock in San Bernardino. What separates our Unilock work here is simple: we build paver patios and driveways for Rialto’s specific combination of high water table, Santa Ana winds, and 100-degree-plus summer days, not for a generic Southern California climate. If your Unilock patio is heaving, your joints are washing out, or your Brussels Block has gone chalky in the sun, call (866) 253-5808 for a straight answer and a free estimate.
Why Rialto Residents Choose Us for Unilock Service
We’ve been running Unilock pavers on Rialto job sites long enough to know which unit profiles hold up on a 1960s ranch lot in 92376 and which ones fight you every step of the way. Nelson Fung, our owner and Rialto General Contractor, learned materials the hard way: staring at tile and concrete samples as a kid at the hardware stalls on Broadway in Chinatown, LA, then years swinging hammers on remodels across the LA basin. That background matters when we’re spec’ing base depth for a Unilock field over saturated subgrade or deciding whether your existing patio needs repair or full replacement. We’re an independent Unilock service provider, not manufacturer-affiliated or authorized, so when we tell you a Beijing Block patio will outlast a poured slab on your lot, that’s field experience talking, not a dealer incentive.
We carry genuine Unilock matching units and Unilock-approved polymeric joint sand for repairs, so color, texture, and joint profile stay consistent across your existing field. For base rock, edge restraint, and drainage, we spec quality generic materials rather than paying a brand premium that doesn’t buy you anything. That’s the honest way to run a Unilock job in Rialto.

Common Unilock Construction Problems We Solve in Rialto
- Efflorescence bloom on Brussels Block. Rialto’s hot, dry summers with irrigation cycling pull soluble salts to the surface of Portland-cement-based Unilock units, leaving a white powdery film. It’s especially bad on north-facing patios in 92376 that get shade and moisture retention. We clean and seal against recurrence, and we’ll tell you honestly what’s cosmetic versus structural.
- Polymeric sand joint failure on Town Hall permeable installs. Santa Ana wind-driven dust plus periodic monsoon rain blows out joints where edge restraint or base compaction was shortchanged. We see this on older Rialto patios where the original installer skipped the open-graded base spec. The fix is joint re-sanding and, often, rebuilding the restraint so the next wind season doesn’t do it again.
- Paver heave and lippage from expansive soils. Parts of Rialto sit on a high water table that standard patio and driveway inspections miss. Paver fields over an under-built base rock shift each wet season, leaving edges sticking up. We test drain-down and build deeper open-graded bases than a typical inland job so the field stays flat.
- UV-faded and chalky face on darker Unilock colors. Charcoal Brussels Block after years of 100-degree-plus summer exposure loses its color and gets a chalky feel. It’s cosmetic but it drives replacement decisions. We can advise on whether color restoration makes sense or whether you’re better off re-topping with Beacon Hill in a lighter tone.
- Driveway edge failure on paver driveways. Rialto’s 92377 area has newer larger homes, and many have paver driveways that lose edge units because the restraint wasn’t tied to a proper concrete haunch. We rebuild edges with a deep, locked-in restraint so the field doesn’t creep outward.
Unilock Service in Rialto: What Local Conditions Mean for Your Equipment
Here’s something most paver pages won’t tell you: the high water table under parts of Rialto, especially in the older 92376 ranch tracts, is the single most overlooked cause of Unilock failure in this city. You can’t see it from the surface. But on Unilock installations here we test drain-down before we ever lay a unit, and we build a deeper open-graded base than we would on a dry inland lot five miles east. Why? Because a paver field over saturated subgrade heaves and shows lippage within one or two wet seasons regardless of how well the units are made. Unilock makes a good paver. It can’t fix a bad base. On a 1960s ranch home off Riverside Avenue in the 92376 ZIP, we tore out a heaved concrete patio and installed a Brussels Block patio with a deepened open-graded base and proper edge restraint after finding the subgrade staying wet. Two seasons of Santa Ana wind and summer sun later, the joints held and the field stayed flat where the old slab had cracked. That’s the difference between knowing Rialto and just knowing pavers.

Unilock Models & Products We Service in Rialto
We install and service the full range of Unilock segmental paving and retaining wall products, including:
- Brussels Block – tumbled, small-format, cobble look. Popular for Rialto patios in 92376.
- Brussels Dimensional – large-format tumbled slab for a smoother, more contemporary finish.
- Town Hall – permeable, open-graded segmental paver for driveway and walkway applications where drainage matters.
- Beacon Hill – flagstone-style concrete paver that reads more natural and hides UV fading better than darker units.
- Sandon – thin-profile tumbled paver for overlays on existing concrete pads.
When we repair an existing Unilock field, we source genuine matching units and Unilock-approved polymeric joint sand so the color, texture, and joint profile stay consistent across the whole surface. For base, edge restraint, and drainage we use quality generic materials, because the brand premium there doesn’t buy you a better result. Repair is almost always the right call for isolated settlement or joint loss; full replacement only makes sense when the base itself failed or your color line has been discontinued.

What drives the cost on a Rialto Unilock job is base depth and drainage prep. If we’re building over saturated subgrade in 92376, the excavation and open-graded base work is heavier than a standard inland install. That’s not a markup. That’s the job done right. A free estimate with us includes a look at your drainage, your existing base (if any), and a written line-item quote, not a round number. Call (866) 253-5808 to schedule yours.

FAQs – Unilock Construction in Rialto
Yes, Unilock pavers hold up well in Rialto’s heat if the base is built for it. The pavers themselves won’t crack under normal thermal expansion the way a poured slab can, but the base and edge restraint must be spec’d for Rialto’s high water table and expansive soils. On a dry, compacted base, a Unilock driveway in 92377 will outperform concrete over a decade. On a wet, under-built base, even the best paver will heave. Call (866) 253-5808 for an exact quote on your driveway, estimates are free.
That’s efflorescence, and it’s extremely common on Brussels Block in Rialto because our hot, dry summers with irrigation cycling pull soluble salts out of the Portland cement in the units. It’s cosmetic, not structural, but it’s persistent. We clean it off and seal the surface to slow its return. If it keeps coming back despite sealing, the issue may be water wicking up from below, which we can diagnose when we’re on site.
In most Rialto cases, a paver driveway replacement on the same footprint does not require a building permit, but if you’re expanding the driveway, adding a retaining wall over three feet, or changing drainage patterns, the city may require one. Rialto has stricter local amendments to the California Building Code in some areas, particularly around water management. We handle permits when they’re needed and can tell you upfront whether your project triggers one.
Yes, and we do it regularly across Rialto. We source genuine matching units from Unilock and blend them into your existing field so the color and texture differences disappear, especially if your pavers have some UV fade. The bigger question is whether the base under the settled area is sound. If it is, repair is straightforward. If the base has washed out or compacted unevenly, we’ll tell you before we touch a single unit.
The answer is edge restraint and base compaction. Poor edge restraint is the main reason joints blow out on Town Hall permeable installs when the Santa Ana winds kick up dust and rain follows. We install a locked-in edge restraint tied to a concrete haunch and spec an open-graded base that holds the units in place. Call (866) 253-5808 and we can check your existing joints before the next wind season.
