AfterUnilock Construction in Pomona, CA | Barrett & Sons Construction
We provide independent Unilock paver and wall installation across Pomona, from driveways in 91766 to patios in the Lincoln Park historic district. The one thing that makes our Unilock work here different: we plan every base, joint, and edge for expansive clay and the Pomona fault, because that’s what actually determines whether your pavers stay flat for 20 years or start heaving in 18 months. Tom Barrett and his sons run the crews, we pull permits, and every price change comes in writing. Call (877) 610-1318 for a free estimate.
Why Pomona Residents Choose Us for Unilock Service
We’ve been laying Unilock pavers in Pomona long enough to know which patterns hold up on clay and which ones don’t. Brussels Block, Beacon Hill, Richcliff, Lineo - we work with all of them, and we stock enough units locally to turn around repairs without waiting on a slow freight order. Tom Barrett grew up in the Valley, learned the trade at LA Trade-Tech, and has spent the better part of two decades building across Los Angeles, including Kitchen Remodeling in Pomona. He’s not a franchise dispatching strangers. The name on the truck is the name answering the phone.
We’re an independent Unilock service provider, not a manufacturer-owned or authorized dealer. That matters because our loyalty is to your property, not a sales quota. If a base repair calls for commercial-grade crushed stone instead of an OEM-spec fill, we’ll say so. If a wall needs geogrid reinforcement beyond the printed spec because Santa Ana winds hit Pomona harder than El Segundo, we’ll put that in writing and explain why. Our Unilock sales & service work is built around what actually survives here, not what a catalog says should work everywhere.
Common Unilock Construction Problems We Solve in Pomona
- Edge creep and joint widening on paver driveways. Pomona’s expansive clay heaves seasonally - it swells when winter rains arrive and shrinks during 105°F summers. That cycle pushes edges outward on driveways that were laid without adequate base reinforcement. We pull the perimeter units, reset the edge restraint, and recompact the base so the joints stay tight.
- Settling and lippage at paver-to-concrete transitions. The Pomona fault runs through this city, and differential movement concentrates where pavers meet poured concrete - driveway aprons, walkway transitions, garage lips. We see trip hazards here that homeowners in Claremont don’t. The fix is re-setting the transition with a compacted crushed stone wedge and fresh sand, not just patching the low spot.
- Efflorescence and surface scaling from irrigation runoff. In Pomona’s flat western neighborhoods, sprinkler runoff ponds against patio edges and wicks up through the pavers. That’s the white crusty residue you see after the dry season. It’s a drainage problem, not a paver defect. We correct the base pitch and add a geotextile moisture barrier before re-setting units.
- Retaining wall units cracking under wind load. Santa Ana gusts hit 50-60 mph in Pomona’s eastern pinch point every fall. Over-height Unilock walls without geogrid reinforcement lean, crack, and eventually fail. We re-engineer the wall’s reinforcing layers while reusing the original facing units where they’re still sound.
- Shallow bedrock ripping up standard base prep. In the parts of 91766 that sit within two miles of the San Jose Hills, bedrock outcrops force a switch from standard excavation to rock wheel saw-cutting. Contractors from Ontario or Chino who’ve never hit that condition lose days and blow budgets. We expect it and bid it from the start.
Unilock Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s the part you won’t find on a national Unilock page. Pomona’s western ZIP codes, especially 91766, sit close enough to the San Jose Hills that shallow bedrock outcrops regularly interrupt paver installations. In flat Ontario or Chino, you dig down, lay base rock, compact, and go. In Pomona, a standard excavation can hit stone two feet below grade, and that changes everything: you need a rock wheel saw-cut, a thinner compacted lift, and often a moisture barrier over the remaining bedrock before the first paver goes down. Skip that step, and your patio becomes a cracked, uneven mess after one wet winter. We plan for bedrock before we quote, so there’s no surprise change order when the crew’s shovel hits granite. Last March, on a Brussels Block patio in the Lincoln Park historic district near Garey Avenue, our crew found the original 2004 installation heaving along the east edge where the clay subgrade meets an old stone retaining wall. We saw-cut the shallow bedrock ledge, removed 38 units, recompacted the clay with a moisture barrier, and reinstalled the pavers with Edge Restraint and fresh joint sand. Six months later the owner reported zero movement even after the first winter rains.
Unilock Models & Products We Service in Pomona
We install and repair the full Unilock paver and wall lineup: Beacon Hill for driveways with a classic tumbled edge, Brussels Block for that old-European cobble look that suits Pomona’s pre-1920 Craftsman homes, Richcliff for a modern linear profile on mid-century ranches, and Lineo for clean contemporary patios. For color-matched repairs, we source genuine Unilock units so new sections blend with aged ones. For base and drainage components, we use commercial-grade crushed stone and geotextile fabric that outperform OEM-specified fills in Pomona’s clay. We repair and re-set individual units when the base rock is intact. We recommend full pavement replacement only when the subgrade failure is widespread - and we’ll show you the evidence before we propose it.
Unilock Service Pricing in Pomona
What you’ll pay depends on site conditions, and in Pomona, site conditions are never neutral. Bedrock proximity, clay depth, drainage pitch, and whether the project is in a historic district all move the number. Here’s where our Pomona work typically lands:
| Service | Typical Pomona Range |
|---|---|
| Paver Driveway Installation | $7,000 - $18,000 |
| Paver Patio Installation | $3,500 - $11,000 |
| Concrete Driveway Installation | $4,500 - $12,000 |
Every estimate is free, written, and line-itemed. If site conditions change mid-job - we hit bedrock, we find clay softer than the test pit showed - you get a written change order before any work proceeds. No surprise invoices at the end.

FAQs - Unilock Construction in Pomona
Yes. Pomona’s expansive clay swells with winter moisture and shrinks in summer heat, so a standard base that works in coastal LA county will heave and shift here. We over-excavate below the clay line, lay commercial-grade crushed stone, add a geotextile separator, and compact in lifts. It’s more work, but it’s the only way a paver driveway stays flat on this soil. Call (877) 610-1318 if you want us to look at your base before you sign a contract.
Paver patios handle differential ground movement better than poured concrete because the joints flex, but only if the base and edges are built for it. We set edge restraints deep, add a compacted crushed stone wedge at any paver-to-concrete transition, and use flexible joint sand so movement gets absorbed instead of cracking units. If you’re near the fault trace, we’ll tell you during the estimate and build accordingly.
We can get close, but a 15-year-old paver has years of Pomona sun and rain exposure that no new unit perfectly matches. We source genuine Unilock Brussels Block in the original colorway and blend new units with your existing ones at the transition line so the eye doesn’t catch the difference. For exact matching, we can pull a unit from a hidden area of your current patio and re-set it in the new walkway, then backfill with the closest new match.
Generally, yes. Individual paver units can shift and re-set without cracking, while a monolithic concrete slab has to crack somewhere when the ground moves. But the system’s only as good as its subgrade. We don’t frame pavers as earthquake-proof; we build them so that when the Pomona fault moves, your patio flexes rather than fails. That starts with a base spec we’ve refined on local jobs since 1998.
That’s efflorescence - minerals wicking up through the paver from trapped moisture below. In Pomona, the usual culprit is irrigation runoff ponding against paver edges on flat lots, especially west of the 57 where the grade runs shallow. We fix it by correcting the base pitch, adding a moisture barrier, and re-setting the affected units. If you’re seeing the white crust, call (877) 610-1318 and we’ll tell you if it’s drainage or something else. The estimate’s free.
