Unilock Construction in Torrance, CA | Barrett & Sons Construction
We provide independent Unilock construction service across Torrance, and while we also handle Kitchen Remodeling in Torrance, the short answer for pavers is this: most failing jobs here trace back to two things, the city’s expansive clay soil and the salt-heavy marine air off Torrance Beach. We’ve been working with Unilock Courtstone, Thornbury, Brussels Block, and Lineo stone on Torrance jobsites for years, and we carry the right base materials and edge restraints to handle what this specific city throws at a paver installation. If your patio or driveway is heaving, spalling, or losing joint sand, call (877) 610-1318 for a straight answer and a free estimate.
Why Torrance Residents Choose Us for Unilock Service
Tom Barrett grew up in the San Fernando Valley, learned framing and build science at Los Angeles Trade-Technical College, and has spent the better part of two decades working across Los Angeles County. He started Barrett & Sons Construction in 1998, and his sons run crews today, including our Unilock sales & service work. We are not a factory-authorized Unilock dealer, and we won’t pretend otherwise. What we are is an independent contractor that handles these paver systems every week, which means we can pull a damaged border, match the existing color tone, and rebuild the base correctly without selling you a full tear-out you don’t need.
In Torrance specifically, that matters. The post-war ranch homes east of Hawthorne Boulevard sit on slab foundations over clay that swells and shrinks with every wet winter and dry summer. A paver patio installed with a thin base will telegraph every soil shift straight up through the surface. We spec base rock, geotextile fabric, and edge restraints for those conditions, not for a showroom floor. And we put every scope and every change in writing before work starts.
Common Unilock Construction Problems We Solve in Torrance
Here’s what we see most often when we pull up to a Torrance home:
- Base settlement and heaving on older slab-on-grade homes. The 1955-1975 tract neighborhoods east of Hawthorne Boulevard sit on expansive clay. When that soil moves, Unilock Courtstone and Brussels Block surfaces can develop dips, ridges, and trip hazards. A patio that looked flat in June can be a lawsuit waiting by February.
- Efflorescence and surface spalling near the coast. The marine layer doesn’t just fog your windows; it keeps paver surfaces damp for months at a time. Salt-laden air accelerates surface degradation, especially on older concrete pavers that have lost their factory sealer. We see chalky white deposits and pitted surfaces throughout the 90501 and 90503 ZIPs near Torrance Beach.
- Edge restraint failure along driveways and walkways. Original plastic or thin aluminum edging from 1970s installations shifts under vehicle loads and soil movement. Once the edge lets go, the whole field of pavers starts wandering outward. We replace it with modern aluminum or steel restraint, buried properly.
- Polymeric sand erosion from irrigation overspray and winter rains. Joint sand washes out, pavers rock underfoot, and weeds push through. This is chronic in Torrance because sprinkler overspray hits paver surfaces daily, and the marine layer keeps joints damp enough that the sand never fully cures.
- Cracked and stained individual pavers with a sound base. When a single Courtstone or Thornbury unit cracks but the base is stable, we replace only the damaged units. Full tear-out is a last resort reserved for failed bases or drainage problems that can’t be fixed any other way.
Unilock Service in Torrance: What Local Conditions Mean for Your Equipment
Here’s something that doesn’t show up on a generic Unilock page: in Torrance’s northern corridor, up near the PBF Energy refinery, any significant paving excavation below 12 inches should trigger a Phase I environmental site assessment before base prep begins. Decades of hydrocarbon operation have left pockets of detectable soil contamination in parts of the surrounding residential grid, and if you discover that mid-project, the permit stops, the budget blows, and everybody stands around waiting. We coordinate that assessment early, because the alternative is a stalled job and an angry homeowner holding a change order they should have seen coming. Contractors in Redondo Beach or Lawndale rarely think about this, but in north Torrance, it’s just how the ground works. We plan for it from day one.
Unilock Models & Products We Service in Torrance
We install and repair Unilock Courtstone pavers, Thornbury pavers, Brussels Block pavers, and Lineo dimensional stone. When color match and structural warranty matter, we use genuine Unilock units. When the base or the jointing is the problem, we use proven aftermarket materials that outperform factory spec for Torrance’s specific soil and moisture conditions: compacted Class II base rock, high-grade geotextile fabric, and polymeric jointing compounds rated for wet coastal environments. We keep common edge restraints and joint sand on hand for quick turnarounds across the 90510, 90501, 90502, and 90503 ZIP codes, so a simple border repair doesn’t sit waiting on a parts order for two weeks.

FAQs - Unilock Construction in Torrance
Most of the time it can be repaired. If the pavers themselves are sound but the base has settled, we lift the affected section, compact a proper base, and re-lay the original units. On a porch retrofit in the Seaside Ranchos neighborhood, we found original 1970s Courtstone pavers with edge spalling and severe joint washout from irrigation mist plus salt air. We pulled the damaged border, added a Class II base and modern aluminum edge restraint, then re-laid the reclaimed Courtstone with high-performance polymeric sand. The color matched, and the patio has decades left in it. Full replacement only makes sense when the base has failed entirely or drainage can’t be corrected.
Efflorescence is a mineral deposit that forms when moisture moving through the paver carries calcium to the surface and leaves it behind as the water evaporates. In Torrance, the marine layer keeps paver surfaces damp for extended stretches, so the cycle runs almost continuously near the coast. You can clean it, but unless you address the moisture source and reseal properly, it will come back. We can’t stop nature, but we can clean, seal, and recommend jointing that slows the cycle dramatically.
For any excavation below 12 inches in the refinery-adjacent northern corridor, yes, plan on it. Decades of hydrocarbon operation have left detectable soil contamination in pockets of the surrounding grid, and finding it mid-project triggers expensive remediation and permit delays. Call (877) 610-1318 and we’ll tell you whether your site is in a zone where this applies before you spend a dollar on base prep.
For soil movement, smaller-format pavers like Brussels Block tolerate flex better than large-format units, because more joints absorb the movement. For salt air and marine-layer moisture, Lineo dimensional stone and denser concrete units resist surface spalling longer than older, more porous pavers. We’ll match the right line to your specific site conditions, not just to a color swatch. Call (877) 610-1318 for a free site assessment.
Driveway replacement typically runs $5,000–$14,000 depending on square footage, base condition, and whether we can salvage any existing pavers. A paver driveway installation lands between $7,000 and $18,000. The only way to get an exact number for your Torrance property is to walk it. Estimates are free, and every scope arrives in writing before work starts. Call (877) 610-1318.
