Unilock Construction in Pomona, CA | San Bruno Construction
We provide independent Unilock paver, wall, and step installation across Pomona, working from the manufacturer’s published base and compaction specs rather than a dealer’s sales sheet. What makes our work here different is simple: we know the slabs under Pomona’s citrus-era and mid-century homes, and we’ll cut one out and re-pour it before we lay good pavers over bad subgrade. If you’re planning a Unilock driveway, patio, or retaining wall in Pomona, call Noel Carvalho and the team at (866) 472-1908 for a free estimate.
Why Pomona Residents Choose Us for Unilock Service
We’re an independent contractor that has installed Unilock pavers, walls, and steps across the San Gabriel Valley for years. Because we’re not tied to Unilock, we’ll tell a Pomona homeowner straight when a failed patio is a base problem the same paver would fail on again. That’s the difference between a contractor who installs pavers and one who builds the substrate they sit on correctly.
Noel Carvalho grew up off El Camino Real in San Bruno and trained in construction technology at Skyline College, where he learned to read plans and understand load paths before a single tool comes out of the truck. That discipline shows up in every Unilock job we run in Pomona, from a small Beacon Hill patio behind a 1920s bungalow near Lincoln Park to a full Umbriano driveway on a 1960s tract lot in 91766. We coordinate all trades, buy genuine Unilock units and matching edge restraints, and pull permits when the job requires them. See our full Unilock sales & service page for the scope of what we handle.

Common Unilock Construction Problems We Solve in Pomona
Most Unilock failures in Pomona start below the paver, not on top of it. Here’s what we typically walk into:
- Edge spalling and joint creep on driveways. When a base is compacted in thin lifts over Pomona’s expansive clay, the pavers rock and chip at the field’s leading edge. We see this constantly on 1950s and 1960s driveways in the 91766 and 91767 ZIPs, where the original slab approaches were poured thin and never addressed before someone laid pavers over them.
- Efflorescence on gray and tan pavers. The hot, dry inland swings and Santa Ana wind cycles pull trapped moisture up through pavers, leaving that chalky-white bloom on Brussels Block and Cambridge Cobble fields. It’s not a paver defect. It’s water trapped under an impermeable base that never should have been laid that way in this climate.
- Retaining wall settlement and lean. Hillside lots near the foothills put real lateral pressure on Unilock walls. When a wall was built without geogrid or proper drainage aggregate, it starts leaning within a few seasons. We rebuild the wall the way it should have been done, with the right reinforcement and a drainage layer behind it.
- Polymeric joint-sand washout at garage-apron transitions. This shows up where a paver field ties into an older concrete slab that wasn’t cut and re-poured to the new grade. The apron settles or drains wrong, water channels through the joints, and the sand washes out. We fix the transition properly instead of just re-sanding.
- Paver skin over a failing slab. A detached 1950s garage gets converted to an ADU, and someone lays pavers over the original slab without checking what’s underneath. The slab has no footing, the clay beneath it moves, and the pavers telegraph every crack. We cut the old slab out, re-pour the approach to code, and then lay pavers.
Unilock Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s the insight that matters for Pomona specifically: the citrus-era and mid-century lots around Lincoln Park and downtown frequently sit on raised or pier-and-beam foundations with detached garages whose original slabs were poured thin, often without proper footings. When we tie a new Unilock patio or driveway into one of these old slabs, the slab itself is usually the weak point, not the pavers. If we don’t address it, we’re laying a beautiful paver field over a surface that will move, crack, and destroy the work within a few seasons.
On a garage-conversion ADU off the Lincoln Park area, our crew pulled the old driveway to pour a proper apron for the new unit and found the 1950s slab had been poured without a footing over expansive clay. We re-poured the approach with a compacted aggregate base and installed a Umbriano paver driveway tied into the new ADU entry, so the field drains to the street and won’t heave when the clay swells. The homeowner got a finished driveway that passed inspection instead of a paver skin over a slab we’d be back to fix.
Unilock Models & Products We Service in Pomona
We install and service the full range of Unilock residential product lines, including Brussels Block (tumbled, dimensional pavers with that old-world texture), Cambridge Cobble (tumbled units with the look of European setts), Beacon Hill (smooth, clean-lined wall and patio units that work well on Pomona’s Spanish Colonial and Craftsman-era homes), and Umbriano (the textured plank-style paver we recommend most often for driveways because it handles Pomona’s heat and traffic well).
On repairs, we buy genuine Unilock units and matching edge restraints. We don’t substitute whatever pallet a yard has on hand. On small repairs we match and relay existing pavers wherever we can. A patio or driveway only gets torn out and rebuilt when the base itself is failing, because relaying good pavers over bad subgrade just resets the same problem.

FAQs – Unilock Construction in Pomona
Rarely. Most pre-1978 garage slabs in Pomona were poured thin and without proper footings over expansive clay, so they move. Laying pavers directly over one means the pavers will telegraph every crack. We inspect the slab first and usually recommend cutting it out and re-pouring with a compacted aggregate base. Call (866) 472-1908 and we’ll take a look at yours.
That’s efflorescence, and it’s common in Pomona’s hot, dry inland climate with its Santa Ana wind cycles. It happens when water gets trapped under an impermeable base and pushes minerals up through the paver. The fix is drainage, not scrubbing. We can assess whether your base is trapping water and what to do about it.
Yes, in most cases. Any hardscape tied to a new ADU or garage conversion in Pomona requires review under current building codes, especially with seismic Zone D requirements. We pull permits and coordinate inspections so the finished work passes the first time. Call (866) 472-1908 or ask about Upland Unilock service for your ADU’s patio or driveway scope.
In most cases, yes, but the real question is why it’s leaning. If it was built without geogrid or proper drainage aggregate into a hillside lot, the wall needs to be rebuilt correctly, not just pushed back. We’ll assess the wall, explain what failed, and give you an honest answer on Unilock repair in Montclair or rebuild options. Estimates are free at (866) 472-1908.
Yes, Unilock in La Verne and Pomona handles heat and wind well when the base is built right. The pavers themselves won’t fail from 95°F summers. What fails is a base compacted in thin lifts over expansive clay, or a poorly tied-in concrete apron. We build the base to Unilock’s published specifications, which is what actually determines longevity here. Call (866) 472-1908 for an exact quote on your driveway.
