Unilock Construction in San Bernardino, CA | Alder Contractors
We provide independent Unilock paver installation and repair across San Bernardino, from downtown Craftsman neighborhoods to foothill properties in 92407, and also offer Unilock service in Muscoy. What makes our work here different is simple: we build for the Cajon Pass wind corridor. That means wind-rated edge restraints, stabilized joint sand, and base compaction methods tuned to San Bernardino’s expansive clay soils, not a generic spec sheet. Call (833) 467-7020 for a free estimate on paver driveways, patios, replacements, or repairs.
Why San Bernardino Residents Choose Us for Unilock Service
Unilock pavers are a premium product, but they only perform as well as the base underneath them. We’ve spent years working with Unilock sales & service product lines across the Inland Empire, and that experience tells us exactly where shortcuts show up later. Nelson Ibarra, our owner, grew up in the Willow Avenue corridor of Rialto and studied building technology at Chaffey College before spending three decades on Inland Empire job sites. He taught our crews one rule that applies to every paver project we touch: do it right the first time – the callback always costs more than the extra hour up front.
We serve the entire San Bernardino area as an independent contractor, not a manufacturer affiliate. Our clients get honest material guidance, OEM-recommended edge restraints and polymeric sand, and a crew that has seen how Unilock pavers actually hold up through triple-digit summers and winter wind events. We’re not reading a spec sheet to you. We’re telling you what we’ve fixed, replaced, and installed across 92401, 92402, 92403, and 92404, plus our Unilock in Highland projects.

Common Unilock Construction Problems We Solve in San Bernardino
- Paver shifting from Santa Ana winds. The Cajon Pass funnels wind directly into San Bernardino’s northern neighborhoods. Exposed driveways lose joint sand fast, and once that sand goes, pavers start walking. We re-set shifted units, re-compact the base, and install wind-rated edge restraints that hold the perimeter. This is one of our most frequent calls in the fall and winter months.
- Color fading from desert UV exposure. San Bernardino summers regularly top 105°F, and darker Unilock colors like Richcliff’s smoked shades absorb that heat and fade faster than lighter tones. We help clients select colors that age better under our sun, and we can clean and re-seal existing surfaces to restore depth without replacing the whole patio.
- Efflorescence on older neighborhood patios. In downtown 92401 and 92410, original housing stock sits on soils that hold moisture. When base compaction was never done right, water pools under pavers, wicks up through the joints, and leaves that chalky white residue on the surface. We address the drainage problem first, then clean the pavers. Skip the drainage fix and the efflorescence comes back.
- Edge restraint failure in foothill yards. Properties in 92404 and 92407 sit on expansive clay that swells and shrinks with moisture. Standard plastic edging flexes, spikes pop out, and the paver field starts creeping. We use rigid edge restraints sized for soil movement, which keeps Unilock borders tight and straight years longer.
- Base failure under older driveways. A paver driveway is only as good as what’s underneath it. In San Bernardino’s mid-century tract neighborhoods, we regularly find original driveways built on thin gravel bases never meant for vehicle loads. We replace the base properly, compact it in lifts, and run the numbers on load-bearing depth before the first paver goes down.
Unilock Service in San Bernardino: What Local Conditions Mean for Your Equipment
San Bernardino is not a flatland city. The foothill edges of 92407 and 92404 fall inside the wildland-urban interface, where the city’s brush-fire history drives defensible-space and ember-resistant construction requirements. Here’s what that means if you’re planning a Unilock paver project on a foothill property: even a hardscape addition can trigger a WUI review, and older properties often need a separate right-of-way permit for the driveway apron where it meets the street. The city’s historical building department runs its own process, distinct from what you’d face in Fontana or our Unilock in Rialto service area. We handle that paperwork weekly. Our crews know which permits apply, when a soils report gets requested, and how to phase the work so the paver installation isn’t held hostage by a review delay. Most flatland contractors inland never touch these requirements, and they show up on the wrong side of a stop-work order because of it.
Unilock Models & Products We Service in San Bernardino
Our crews work regularly with Unilock’s core paver families: Brussels Block, Beacon Hill, Richcliff, and Town Hall. Each one performs differently under San Bernardino conditions. Brussels Block, with its tumbled edges and varied surface, hides minor shifting better than a tight-fit product like Town Hall, which shows every millimeter of movement. Beacon Hill’s larger format moves less but demands a dead-flat base. Richcliff’s modular look suits modern homes in newer foothill developments, but its darker tones need the UV conversation. We keep common edge restraints and polymeric sand stocked for fast turnaround on repairs across San Bernardino, and for replacement or additions we order from local supply chains, not drop-shipped pallets from out of state.

AfterUnilock Service Pricing in San Bernardino
Paver work in San Bernardino is priced on a few variables: access, base condition, total square footage, and whether we’re repairing or replacing. Here’s where typical project budgets land:
| Service | Typical Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
What drives the spread is base work. A paver patio over flat, compacted soil runs toward the lower end. A driveway that needs full excavation, new gravel base, and wind-rated edge restraints runs higher. Our free estimate includes a written line-item breakdown before you commit to anything, and the number we quote is the number we build to. Call (833) 467-7020 to schedule yours.

FAQs – Unilock Construction in San Bernardino
Strong, dry winds funneling through the Cajon Pass scour joint sand out of paver surfaces, especially on exposed driveways and patios facing the windward side. Once the joint sand goes, pavers shift and the surface loses structural integrity. We install wind-rated edge restraints and use stabilized polymeric sand designed for high-wind exposure, which locks joints far longer than standard sand. Call (833) 467-7020 if your paver joints are blowing out – we’ll assess it free.
Yes, but only with the right base preparation. Expansive clay swells with moisture and shrinks in drought, which moves the subgrade under your pavers. We over-excavate, install a properly graded aggregate base, and sometimes specify a geotextile separator to keep clay from migrating into the gravel. Skip that step and you’ll see heaving within two or three wet seasons in 92404 or 92407.
Often yes, especially on older properties where the driveway apron meets the public right-of-way. The city requires a right-of-way permit for that section, and foothill properties may trigger a wildland-urban interface review even for hardscape. We pull the permits and pass the inspections. For an exact answer on your street, call (833) 467-7020 and we’ll check the address.
Consistent 105°F-plus summers accelerate UV degradation on darker paver colors, and surface temperatures on dark pavers can exceed what lighter tones reach by a wide margin. The pavers themselves remain structurally sound for decades, but the color mutes faster. We recommend lighter colorways for full-sun exposures in San Bernardino and can apply a quality sealer to slow fading on existing installations.
First, fix the drainage and base compaction problem that’s letting water pool under the pavers – that’s the root cause in older downtown neighborhoods. Then clean the surface with an efflorescence-specific cleaner, not muriatic acid, which can etch the paver face. Re-seal after the surface is dry and the drainage is corrected.
