Unilock Construction in Los Angeles, CA

Unilock Construction in Los Angeles, CA | Rowan Construction Group

We provide independent Unilock paver installation and repair across Los Angeles, from hillside patios in Silver Lake to flatland driveways & pavers in Los Angeles in the San Fernando Valley. The one thing that makes our Unilock work here different is that we plan for what Los Angeles does to hardscape: expansive clay that heaves, seismic retrofit ordinances that reshape building scopes, and a sun load that fades lesser products. Call (470) 298-9650 for a written estimate before any work starts.

Why Los Angeles Residents Choose Us for Unilock Service

We’re not an authorized Unilock contractor, and we say that plainly because it matters. What we are is a crew that has installed and repaired Unilock product lines across Los Angeles’s varied terrain for years, which means we know how Beacon Hill Flagstone behaves on a slope and how Brussels Block holds up under Valley heat. Our founder, Grant Rowan, grew up in the Crenshaw district and trained in construction technology at Los Angeles Trade-Technical College, where the coursework covered concrete and estimating before he ever touched a paying job. That background means we quote Unilock work the way we build it: with numbers on paper, not guesses. We offer flat written pricing before the first paver is set, and every visit includes a documented photo record so you can see what we found and what we did.

Common Unilock Construction Problems We Solve in Los Angeles

• Paver shifting and heaving on Valley clay. Expansive clay soils across the San Fernando Valley floor shrink during the long dry season, then swell hard after winter rains. That cycle lifts and drops the sub-base beneath Unilock pavers. We see driveways in Van Nuys and Northridge where sections rise a half-inch or more each season. The fix is never just re-leveling the surface pavers; it’s excavating and rebuilding the base.
• Edge restraint failure on hillside installs. In hillside communities through the Santa Monica Mountains, perimeter pavers slide outward over time when edge restraints weren’t anchored for slope and gravity. Silver Lake and Echo Park have the same problem on terrace patios. We re-anchor with proper edging and compacted base, not just cosmetic resetting.
• Fading and surface wear from intense UV exposure. Older Unilock pavers in flatland neighborhoods like Woodland Hills show surface fading after years of direct sun. Some of it is chalky efflorescence; some is genuine pigment breakdown. We tell you which one it is before we recommend anything.
• Joint sand erosion under seasonal downpours. Los Angeles may be dry most of the year, but when winter storms hit, they hit hard. Joint sand washes out of Unilock patios, widening gaps and inviting weeds. We replace with polymer-modified joint sand that holds better through repeated wet-dry cycles.
• Dingbat building ground-level hardscape cracking. Pre-1980 wood-frame apartment buildings over open parking levels, the classic LA “dingbat,” transmit movement down to surrounding ground-level hardscape. Unilock pavers around these structures crack when the base below wasn’t designed flexible enough to absorb structural settling. We build those bases differently.

Unilock Service in Los Angeles: What Local Conditions Mean for Your Equipment

Los Angeles is the only major U.S. city with a mandatory soft-story retrofit ordinance, Ordinance 183893, requiring thousands of pre-1980 wood-frame apartment buildings over open parking levels to be seismically retrofitted on a city-enforced deadline. That structural reality reaches the paver work around those buildings. Any ground-level Unilock hardscape next to a dingbat building must be designed with a flexible sub-base that can absorb structural movement during and after a retrofit, otherwise the pavers crack along load paths no one planned for. A paver patio that would be straightforward in Glendale or Pasadena becomes a different job when the adjacent building is about to be lifted and reinforced. We plan for that on the front end, because redoing hardscape after a retrofit is more expensive than doing it right the first time.

Unilock Models & Products We Service in Los Angeles

We work with the full range of Unilock concrete paver products, with the most common in Los Angeles being Beacon Hill Flagstone for organic-looking patios, Brussels Block for driveways and walkways, Copthorne for a more formal modular look, and Richcliff for a contemporary linear aesthetic. For repairs, we use OEM Unilock pavers and matching joint sand whenever possible to keep color and dimensional consistency, sourcing locally from LA masonry suppliers to manage lead times. When heaving has compromised the base, we’ll tell you honestly that patching surface pavers rarely lasts more than one wet season in our expansive soils. Full replacement of the damaged section is the only fix that holds.

FAQs - Unilock Construction in Los Angeles

Will Unilock pavers shift on my Los Angeles property if I live in a hillside area like Silver Lake?
Yes, they can, if the base wasn’t engineered for slope. Hillside patios need deeper excavation, properly anchored edge restraints, and compacted aggregate that resists downward creep. Our crew recently replaced an old asphalt driveway with Unilock Brussels Block for a homeowner in Woodland Hills, where the expansive clay had caused the asphalt to heave and crack every winter, as part of our Fence Installation - Los Angeles and hardscape services. We excavated 12 inches, installed geotextile fabric and a new 6-inch compacted aggregate base, then laid Brussels Block with a sand-set jointing compound. Two winters later, the driveway shows no movement, and the owner told us it was the first time they hadn’t had to patch after the rains. Call (470) 298-9650 to have us assess your slope.

My Unilock patio in the San Fernando Valley has sunken areas after winter rains. Is that a pavers problem?
Usually it’s a base problem, not a paver problem. The pavers are fine; the compacted layer underneath wasn’t thick enough or was built on unprepared expansive clay. Patching the surface won’t fix it because the movement is coming from below. We excavate to proper depth, install or restore the base, and re-lay the same pavers if they’re still sound. Call (470) 298-9650 for a written assessment.

Can you match my existing Unilock pavers if I only need a small driveway repair?
In most cases, yes. We source OEM Unilock pavers from local LA masonry suppliers to match color and dimensions as closely as the product’s current production allows. Older pavers may have UV-faded, so a perfect match isn’t always possible, but we’ll show you the comparison before we install anything. For a precise quote on your specific product, call (470) 298-9650.

Are Unilock pavers strong enough for a driveway in Los Angeles with our earthquake and soil movement?
Yes, when the base is built for it. Unilock driveway pavers have compressive strength ratings that handle vehicle loads fine. The failure point in Los Angeles is almost always the sub-base: expansive clay, inadequate compaction, or missing geotextile. We build bases to stay stable through wet-dry cycles and minor seismic movement. Call (470) 298-9650 and we’ll show you what a proper base looks like.

How do I get a same-day permit for a Unilock paver patio in Los Angeles?
Patio and hardscape work that doesn’t add structural elements often qualifies for over-the-counter same-day permits through LADBS, but adding a single structural element, like a raised planter wall or a covered structure, pushes the project into the standard queue. That’s a three-to-five-month delay in Los Angeles, which can kill a financing or ADU timeline. We structure scopes carefully to stay in the over-the-counter lane when possible. Call (470) 298-9650 and ask us about permitting for your specific site.
