We’re not a manufacturer-authorized dealer. We’re an independent Unilock service provider, which means we tell you the truth about what works on Riverside soil whether that’s a genuine Unilock unit or a smarter base design the catalog never mentions. Tom Barrett has been building in Southern California since 1998, and his sons run our crews. If you want to look us up before you call, our license number is published right alongside Tom’s name and address. Ask anyone on your street, or look up the license number yourself.

Why Riverside Residents Choose Us for Unilock Service

We actually know Unilock’s product lines, and we know what happens to them on Riverside ground. Most hardscape crews can lay pavers on flat, stable soil. But Riverside isn’t most places. Our crews have rebuilt Unilock installations after clay heave, after seismic settling, after edge restraint failure that other contractors walked away from. We understand why a Unilock Richcliff driveway in the Wood Streets behaves differently than the same paver in Irvine.

Tom Barrett grew up in the San Fernando Valley watching crews pour foundations with his dad on weekends. He learned the trade at Los Angeles Trade-Technical College, and the last two decades have been spent building, Kitchen Remodeling in Riverside, and remodeling across Southern California. His oldest boy showed the same interest in tools at sixteen, and that’s how Barrett & Sons got its name. We run background-checked crews who carry the Barrett & Sons name on their shirts. A live person answers our phone 24/7, not a voicemail box.

Common Unilock Construction Problems We Solve in Riverside

• Edge restraint failure on expansive clay. Riverside’s Vertisol clay swells in winter and shrinks in summer. Pavers migrate outward as the soil moves, leaving gaps at the perimeter. We re-set with deeper base and geo-grid reinforcement so the edges actually hold.
• Sand joint washout on sloped driveways. Heavy downpours hit Riverside hard, especially near Alessandro Heights. Joint sand washes out, pavers start rocking, and the surface wears unevenly. We re-joint with polymer sand and correct drainage so it doesn’t happen again.
• Base material breakdown from clay subgrade moisture swings. When the clay under a paver bed holds water, the base breaks down and the pavers settle unevenly. We see undulating patios and walkways all over Riverside’s older neighborhoods. The fix is excavation, fabric separation, and proper compaction.
• U-Cara wall panel joints opening up behind hillside retaining walls. Box Springs Mountain foothill zones see water retained behind walls, and the panel joints open up over time. We address the drainage problem first, then re-set the panels.
• Discontinued color matching. Unilock changes their color runs over the years. When a section of driveway needs patching and the color’s discontinued, we source quality aftermarket equivalents and test for freeze-thaw and efflorescence resistance before quoting.

Unilock Service in Riverside: What Local Conditions Mean for Your Equipment

Here’s the thing most Unilock pages won’t tell you: Riverside’s city engineering department requires preliminary soils reports for any paver project over 1,000 square feet. The reports flag expansive Vertisol clay in most neighborhoods below the Box Springs foothills. That’s not a formality. It changes the entire subgrade design. Unilock installations in Riverside demand a heavier crushed-rock base and deeper excavation than anything a coastal contractor quotes. We’re talking 18 inches of over-excavation in some spots, with fabric-separated Class II road base and re-compaction in lifts. Out-of-area bids routinely omit $1,500 to $4,000 in subgrade prep, and the homeowner finds out when the pavers heave two years later. We price it in from the start because we’ve already seen what happens when you don’t.

Last summer our crew rebuilt a Unilock Richcliff paver driveway in the Wood Streets neighborhood after the original base cracked from clay swell. The pavers had heaved upward nearly two inches at the garage apron. We excavated down 18 inches, installed fabric-separated Class II road base with vertical edge restraints, re-compacted in lifts, and re-laid the Richcliff units with polymer sand. The homeowner now reports zero movement through a full wet-dry cycle. We’ll do it right the first time, or we’ll come back and make it right.

Unilock Models & Products We Service in Riverside

We work with Unilock’s full hardscape catalog, and we can tell you which lines hold up best on Riverside soil. Estate Series pavers like Rivenstone and Courtstone give you that old-world texture, but the base underneath matters more than the paver on top. U-Cara Multi-Face Wall System panels are popular for hillside retaining walls, and Brussels Block pavers still show up in a lot of Riverside’s older patios. We prefer genuine Unilock replacement units to match color and dimensional tolerances exactly. When a color’s discontinued, we source quality aftermarket equivalents and test them before quoting. We replace individual damaged pavers when the base is sound. If base failure is causing recurring movement, we recommend full re-installation rather than piecemeal repairs.

FAQs - Unilock Construction in Riverside

How does Riverside’s expansive clay affect a new Unilock paver driveway compared to a concrete slab?
Unilock pavers actually handle clay movement better than a monolithic concrete slab because individual units can flex at the joints. But that only works if the base is built for it. A concrete slab on expanding clay cracks and heaves as one piece. Pavers on a properly engineered base, with deeper excavation and geo-grid edge restraints, move slightly and settle back. The key is the base. Most Unilock failures we see in Riverside are base failures, not paver failures. Call (877) 610-1318 and we’ll talk through your specific lot.

What’s the most common Unilock failure you see in hillside neighborhoods like Alessandro Heights?
Joint washout on sloped driveways. When a heavy rain hits a sloped Unilock driveway, the sand washes out of the joints and the pavers start rocking under vehicle weight. Without joint sand holding the units in place, the whole surface shifts over time. We re-joint with polymer sand that hardens after wetting, and we grade the slope for proper drainage. If your driveway’s rocking after rain, call (877) 610-1318 before the pavers start cracking.

Can you match Unilock Richcliff pavers installed 10 years ago if I want to extend my patio?
Sometimes yes, sometimes not. Unilock changes their color blends over time, and a Richcliff paver installed ten years ago has also weathered in Riverside’s sun. We’ll bring out samples from the current Richcliff line and compare them against your existing units in daylight. If the match is close enough, we’ll use genuine Unilock. If the color’s discontinued, we source quality aftermarket equivalents and test for freeze-thaw and efflorescence resistance before quoting. Call (877) 610-1318 to schedule a sample comparison.

Do Unilock paver driveways need sealing in Riverside’s hot, dry summers?
Sealing is optional, not required. Riverside’s intense summer heat can fade paver color over time, and a quality sealer with UV inhibitors slows that fade. But the real threat to your Unilock driveway isn’t sun, it’s the clay underneath. We’d rather see you spend money on a proper base than on a sealer that mostly makes the pavers look wet. If you want sealing for color retention, we can do it. But get the base right first. Call (877) 610-1318 for honest advice on what your driveway actually needs.

Why did my paver joints fill with mud and weeds after heavy rain?
That’s a drainage problem. Mud gets into paver joints when water carries soil up through the joints or across the surface from an adjacent slope. Weeds take root in whatever organic material collects in the open joints. The fix is cleaning out the contaminated joints, re-jointing with polymer sand, and fixing the drainage so water isn’t flowing over or pooling on the pavers. In Riverside, this is especially common on lots that slope toward the house. Call (877) 610-1318 and we’ll diagnose it.
