Unilock Construction in Foothill Ranch, CA | San Bernardino Contractors
We provide independent Unilock paver and retaining-wall construction across Foothill Ranch as your trusted Foothill Ranch General Contractor. Most of our work here is tear-out and rebuild of 1990s hardscape that’s failing on sloped, clay-heavy lots. We’re not an authorized Unilock dealer, but we know these products well enough to tell you when a surface can be saved and when it needs to come up. Call (855) 473-5620 for a free estimate.
Why Foothill Ranch Residents Choose Us for Unilock Service
Unilock pavers show up all over Foothill Ranch because the Mediterranean and Spanish-revival tract homes built in the late 1980s and 1990s were originally designed with them. Driveways, patios, walkways, and low retaining walls using Brussels Block and Cambridge Cobble are everywhere. What makes our work different is that we understand what happens to those pavers after 25 to 35 years on this terrain. Ruben Castillo, our owner, learned framing and concrete the hard way, watching his uncle reroof and rebuild houses in San Bernardino’s Westside. That background shapes how we approach base prep, drainage, and grade on every Unilock job. If the base isn’t right, no paver on top of it will stay put. We also offer Unilock sales & service, so whether you need new material or a repair on existing hardscape, we can handle both.

Common Unilock Construction Problems We Solve in Foothill Ranch
- Efflorescence and salt bloom on Brussels Block and Cambridge Cobble. Foothill Ranch lots with irrigation runoff trapped against the house keep paver bases damp. That moisture pulls minerals up through the paver, leaving white chalky deposits on the surface. We clean the bloom and address the drainage that caused it.
- Edge spalling and paver walk-out on driveways and patios. Expansive clay under Foothill Ranch swells in wet winters and shrinks in dry summers. Bases that weren’t engineered for that movement let pavers shift outward along the edges. We reset the edge restraint and rebuild the base where it’s failed.
- Differential settlement on sloped lots. Many Foothill Ranch homes sit on grades that pitch toward Whiting Ranch or the foothills. Unilock patios and walkways on those slopes develop joints that open up and trip lips at transitions. We lift, re-grade, and reset so the surface reads flat and drains properly.
- Faded or chipped surface color after 20+ years of Santa Ana wind and UV. The dry, hot wind events that sweep through the Santa Ana foothills take a toll on paver color. Older Unilock units can look sun-bleached and brittle. We color-match replacement units where possible.
- Retaining-wall block face cracking behind Estate Wall systems. When drainage behind a Unilock Estate Wall was never addressed, hydrostatic pressure builds and cracks the wall face. We rebuild with clean gravel, weep holes, and proper backfill so the wall doesn’t fail again.
Unilock Service in Foothill Ranch: What Local Conditions Mean for Your Equipment
While we also offer Portola Hills Unilock service, Foothill Ranch is essentially built out against Whiting Ranch Wilderness Park and Limestone Canyon. There’s no undeveloped land left. That means nearly every Unilock paver or retaining-wall job here is a tear-out and rebuild of a 1990s-era hardscape rather than new-lot installation. The original wood decks and balconies from that build-out are failing in bunches, and the hardscapes underneath them often need attention too. Base prep and demolition of the old failed assembly drive the scope and cost more than the pavers themselves. On a home off Saddleback Ranch Road backing toward Whiting Ranch, our crew tore out a 1990s paver patio whose Unilock Cambridge Cobble had heaved and walked out along the slope edge. We re-graded the sub-base for the clay, added proper drainage away from the house, and reset the field with color-matched Cambridge Cobble plus new polymeric joints, so the patio drained and locked back together instead of puddling at the wall. That’s the kind of work this community needs, and it’s why we approach Foothill Ranch jobs differently than flatland subdivisions.
Unilock Models & Products We Service in Foothill Ranch
We work on the Unilock lines most common in Foothill Ranch: Brussels Block, Cambridge Cobble, Estate Wall retaining-wall systems, and Beacon Hill Flagstone. When a repair needs replacement units, we source genuine Unilock pavers and wall blocks so the new material blends with the existing field. For patio and driveway rebuilds, we use quality compactable base and polymeric joint sand, not whatever bag is cheapest. Our stance is honest: isolated spalled or settled units get lifted and reset. A driveway or patio on a failed base gets rebuilt, because patching over bad base just buys one more season. If it’s not built right the first time, you’re just paying for it twice.

FAQs – Unilock Construction in Foothill Ranch
Yes. Concrete pavers like Unilock Brussels Block and Cambridge Cobble are non-combustible, so they’re compliant with Chapter 7A ignition-resistant material requirements in Foothill Ranch’s wildfire-urban interface zones. The pavers themselves aren’t the issue. What matters is the ember-resistant venting and ignition-resistant detailing on the adjacent structure, which we coordinate as part of the overall hardscape and exterior scope. Call (855) 473-5620 for a free assessment of your specific lot.
No. We’re an independent general contractor. San Bernardino Contractors is not authorized, sponsored, or endorsed by Unilock. That independence means we give you straight answers about when a Unilock surface can be repaired versus rebuilt, without pushing you toward replacement because a manufacturer program says so.
Yes. We source genuine Unilock units for color-matched repairs and expansions. Aftermarket pavers rarely match the color, profile, or texture of a 25-year-old field, and the mismatch is obvious from ten feet away. We’d rather take the time to find the right unit.
Most isolated repairs, like resetting a settled paver or fixing edge spalling, take one to two days. A full patio or driveway tear-out and rebuild typically runs three to seven working days, depending on access, slope, and whether we need to re-engineer the base for expansive clay. We’ll give you a schedule before work begins.
Patio installations run $3,500 to $11,000. Paver driveways are $7,000 to $18,000. Driveway replacement runs $5,000 to $14,000, and sealing is $250 to $700. The biggest cost driver in Foothill Ranch is demolition and base repair on older 1990s hardscapes. Call (855) 473-5620 for an exact quote, estimates are free.
