Unilock Construction in Long Beach, CA

Unilock Construction in Long Beach, CA | Rowan Construction Group

We install, repair, and reset Unilock pavers, patios, driveways, and retaining walls across Long Beach as an independent contractor - not a manufacturer affiliate. What sets our Unilock work apart here is that we consult seismic and subsidence maps before we ever set a base, because ground movement in this city is not a hypothetical. If your Unilock patio or walkway has shifted, cracked, or separated, call (470) 298-9650 for a written quote before any work starts.

Why Long Beach Residents Choose Us for Unilock Service

Grant Rowan founded Rowan Construction Group in 2007, and he trained in construction technology at Los Angeles Trade-Technical College before spending two decades on residential and light commercial projects across LA County. That background matters when you’re dealing with a paver system that failed because the ground underneath it moved. We’ve rebuilt enough Unilock installations in Long Beach to know the difference between a base problem and a paver problem, and we write that difference into a line-item quote. Our crews are background-checked and uniformed, and every visit includes a documented photo record, so you see what we found and what we did. We’re an independent Unilock sales & service provider, which means we quote OEM and aftermarket fixes based on what actually holds up in Long Beach, not what a corporate rep tells us to say.

Common Unilock Construction Problems We Solve in Long Beach

• Paver drift and edge separation on canal-adjacent lots. Naples Island and Belmont Shore sit on chronically saturated soil. Standard sand-set bases shift as the ground swells and contracts, so Unilock pavers migrate toward the canal slope or separate at the edges. We fix this with deeper excavation, geogrid reinforcement, and proper drainage, not just more sand.
• Efflorescence and salt-spall pitting on coastal pavers. The marine layer within a mile or two of the shoreline leaves a persistent chalky white residue on Brussels Block and Umbriano pavers. We treat the source, reseal when the type permits, and advise on long-term maintenance for salt-air exposure in Long Beach.
• Retaining wall settlement in Wrigley and Rose Park. Older Unilock walls in these pre-1940 neighborhoods were often built on bases that never accounted for historic subsidence differentials. We see wall faces bulging or the first course sinking while the rest stays put. The fix usually requires partial dismantling and base reconstruction.
• Rutting and joint blowout on driveways near retrofit zones. Long Beach’s mandatory soft-story retrofit ordinances bring heavy equipment onto residential blocks. Unilock driveway pavers in those neighborhoods can rut or blow sand joints under concentrated loads they were never designed to carry. We reset with a compacted base built for the actual traffic.
• Mismatched replacement units after spot repairs. A cracked paver replaced with the wrong color or finish looks worse than the crack. When we replace Brussels Block, Umbriano, Beacon Hill Flagstone, or Town Hall units in Long Beach, we source OEM color-matched pieces for visible areas and document the difference if aftermarket is the only option.

Unilock Service in Long Beach: What Local Conditions Mean for Your Pavers

Long Beach sits directly atop the Newport-Inglewood Fault, and parts of the city also sit over the Wilmington Oil Field, which subsided by as much as 29 feet in the worst areas before injection programs stabilized the ground. For Unilock pavers, that means something very specific: in West Long Beach and near Terminal Island, two neighboring lots can sit at measurably different original grades. A contractor who assumes a standard 4-inch base and 1% slope is guessing. We request historical subsidence maps before bidding foundation-dependent work in those zones, and we check elevation differentials across the project area before we quote. What looks like a simple patio reset is sometimes a full regrade with soil stabilization. That is the Long Beach-specific difference, and it is why we price our Long Beach service area projects with a written scope that names the base depth, drainage path, and any regrade work, so you are not surprised when the real condition shows up.

Our crew was called to a 1930s bungalow in Rose Park where the homeowner’s Unilock Brussels Block walkway had buckled in several spots. After pulling permits and checking historic subsidence maps, we found the original sand base was undercut by differential settling that left a 4-inch drop across a 20-foot run. We re-excavated, added geogrid and crushed base, re-set the existing pavers with OEM replacements for about 40 cracked units, and the walkway now holds level through the winter wet season. Measure twice, say it once, show your work.

Unilock Models & Products We Service in Long Beach

We work on the full range of Unilock lines commonly installed across Long Beach: Brussels Block, Umbriano, Beacon Hill Flagstone, and Town Hall. Brussels Block and Town Hall are the workhorses on older driveways and walkways in Wrigley and Rose Park. Umbriano shows up frequently on Belmont Shore patios, and Beacon Hill Flagstone is common on higher-end yards throughout the east side. For visible patios and walkways, we source OEM replacements so the color and surface texture stay consistent. For base repair and reseating, we often recommend aftermarket polymeric sand and bedding materials where they perform as well or better for less money. We are straightforward about the threshold: if the original base has failed across more than 30% of the area, or if UV fading makes patch-matching impossible, we tell you replacement is the honest call rather than selling you a patch that will look wrong in a year.

FAQs - Unilock Construction in Long Beach

Do Long Beach’s seismic retrofit ordinances affect how we should install Unilock pavers around a soft-story building?

Yes, because retrofit work brings heavy lifts and equipment onto residential lots, and the paver base near the building has to carry loads it was never designed for. We specify a deeper compacted base and geogrid reinforcement around soft-story buildings in Long Beach, and we coordinate the paver work with the retrofit schedule so the pavement goes in after the heavy equipment is done. Call (470) 298-9650 to talk through your specific site.

Why do our Unilock pavers near Belmont Shore show white chalky stains that keep coming back?

That white staining is efflorescence, and in Belmont Shore it keeps returning because the salt-laden marine air and persistent moisture cycle mineral salts up through the paver surface. Coatings without proper surface preparation make it worse. We remove the mineral deposits, address any drainage that is feeding moisture into the system, and recommend a maintenance schedule that fits a coastal Long Beach property. Call (470) 298-9650 and we’ll take a look.

Can you match a 20-year-old Unilock Beacon Hill patio if we only need a few units replaced?

Sometimes. If the pavers still carry their original color and the lot is shaded enough to minimize UV bleaching, OEM replacements can blend within an acceptable range. If 20 years of Long Beach sun has faded the surface, a patch will show regardless of what we source, and we’ll tell you that before you spend the money. We’d rather give you an honest answer than a patch that looks wrong.

Is it true that parts of Long Beach need a soils report before installing a Unilock retaining wall?

Yes, in specific areas. West Long Beach, the blocks near the port, and Terminal Island have documented historic subsidence from Wilmington Oil Field extraction, and a retaining wall built without checking the ground’s history can settle or lean within a few years. We request historical subsidence maps and, where the grade indicates unusual movement, recommend a soils report before we bid the base. That is a Long Beach-specific requirement you will not hear from every contractor.

How do you handle Unilock driveway pavers that have shifted after the ground settled from old oil field activity?

We start by identifying where the settlement happened and how much movement there is across the driveway. If the differential is significant, we re-excavate the affected section, stabilize the subgrade, rebuild the base with crushed aggregate and geogrid, and re-set the pavers with OEM replacements where units are cracked. If the settlement continues, we discuss drainage and soil stabilization before the pavers go back down. Call (470) 298-9650 and we’ll quote the repair with a written scope.
