AfterUnilock Construction in Irvine, CA | Rowan Construction Group Irvine
We provide independent Unilock paver and retaining wall construction across Irvine, with pricing written before any work starts and crews who understand how the city’s village-level HOA approvals shape every material choice. The one thing that makes our Unilock work here different: we’ve navigated ARC approvals in Woodbridge, Turtle Rock, Northwood, and the Great Park Neighborhoods enough times to know that the paver palette we’re allowed to install changes block by block, and we plan for that delay in every quote. Call (657) 227-2502 to schedule your free estimate.
Why Irvine Residents Choose Us for Unilock Service
We’ve placed Unilock sales & service work across Irvine since before the Great Park Neighborhoods broke ground, and we’ve learned that generic paver knowledge doesn’t survive here. The city’s dual-approval reality - City of Irvine building permits plus village-level HOA Architectural Review Committees - means a contractor who knows the product but not the process will leave you with pallets of Brussels Block you can’t legally install.
Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College before founding Rowan Construction Group in 2007. His crew has worked the Irvine Spectrum area specifically, where mixed commercial-residential zoning and tight HOA standards keep every scope honest. We source genuine Unilock units for visible faces and use quality aftermarket polymeric sand and edge restraint where spec allows. Every project gets a written flat price before work begins, a documented photo record on every visit, and our 365-Day Done Right Promise backed by The Haven Standard. Measure twice, build it once, write it down.
Common Unilock Construction Problems We Solve in Irvine
- Efflorescence bloom on Brussels Block and Beacon Hill Flagstone - Irvine’s dry-season irrigation cycles, especially where HOA-maintained turf meets paver edges, drive calcium salt deposits to the surface. We see this most in older villages like University Park where sprinkler heads were retrofitted after original hardscape installation. The fix isn’t acid washing; it’s identifying the irrigation overlap and resealing with a breathable silane-siloxane treatment.
- Polymeric sand washout along driveway aprons and walkway edges - Fall Santa Ana wind events drive rain horizontally across exposed edges, stripping incompletely cured joint sand. In Woodbridge, we pulled a failed driveway apron where Brussels Block had been laid over an uncompacted base and the polymeric sand was washing out toward the HOA sidewalk every Santa Ana event. We re-excavated, reset edge restraint to the correct grade, and re-laid with matching Unilock Brussels Block so the ARC wouldn’t flag a color mismatch. The result held through the next wind season and the homeowner passed the HOA’s follow-up inspection.
- Edge restraint failure on Umbriano driveways - The smooth, mottled finish of Umbriano shows every base flaw, and we’ve found multiple Irvine jobs where base compaction was spec’d for the flat HOA grade rather than the actual slope of the driveway. Water follows the true grade, undermining the restraint. We compact to the measured slope, not the assumed one.
- Joint shifting and lippage on Pisa II wall caps - Taller hillside terraces in Turtle Rock and Northwood need the manufacturer’s geogrid spec followed exactly. Skipping layers to save on fill creates cap movement within two wet seasons. We pull the spec sheet and build to it.
- Color mismatch on replacement sections - Unilock’s dye lots shift year to year, and ARCs in Irvine’s master-planned villages often require original or approved-equivalent materials. We source from Unilock’s West Coast distribution to minimize lot variance, and we document the existing color with photos under neutral light before ordering.

AfterUnilock Service in Irvine: What Local Conditions Mean for Your Equipment
Irvine’s village-level HOA Architectural Review Committees - Woodbridge, Turtle Rock, Northwood, and the Great Park Neighborhoods each with their own CC&Rs - must approve paver color, texture, and material before a Unilock order can be placed, so the brand palette we’re allowed to install differs block by block. This isn’t a formality; we’ve seen ARC rejections for Unilock Umbriano in a color approved three doors down because the specific village’s updated design guidelines changed in 2019. We build this approval timeline into every quote, typically adding two to four weeks before material can be ordered. The same process means we can’t start demolition until the ARC approval letter is in hand, or the homeowner faces stop-work orders and redo requirements. Our Irvine service area coverage includes pre-submittal meetings with ARC coordinators to catch palette restrictions before they become change orders.
Unilock Models & Products We Service in Irvine
We work with the full Unilock residential line: Brussels Block for traditional tumbled applications, Beacon Hill Flagstone for natural-stone aesthetics, Umbriano for smooth contemporary finishes, and the Pisa II retaining wall system for grade changes and terrace construction. Because we’re independent - not a Unilock-authorized dealer - we can spec across these lines based on site conditions and ARC requirements rather than pushing current dealer stock. We keep common Brussels Block and Umbriano units in regional supply for fast replacement matching, and we maintain relationships with Unilock’s West Coast distribution to access specific dye lots when ARC approval requires them. For wall work, we stock Pisa II corner units and cap pieces locally; for jointing, we use quality aftermarket polymeric sand rated for the joint width and traffic load, not whatever came cheapest.

FAQs - Unilock Construction in Irvine
Yes, virtually always. Irvine’s master-planned structure means the village-level Architectural Review Committee must approve paver color, texture, and material before work begins, separate from any City of Irvine building permit. We include ARC pre-approval in our project timeline and can assist with submittal documentation. Call (657) 227-2502 to discuss your village’s specific requirements.
Unilock Brussels Block, with its tumbled finish and beveled edges, handles wind-driven debris and thermal cycling better than smooth-faced alternatives in our experience across Irvine. The textured surface hides minor impact marks, and the traditional joint pattern performs well with flexible polymeric sand. For contemporary aesthetics, Umbriano works but requires more precise base drainage to prevent the mottled surface from showing efflorescence streaks.
We can match most Unilock lines if the original dye lot is still in production. We photograph existing pavers under neutral light, document the unit size and finish, and source from Unilock’s West Coast distribution. Where the original color is discontinued, we present the closest current match for your ARC’s approval before ordering. Call (657) 227-2502 and we’ll assess what’s possible.
Three factors dominate: premature exposure to irrigation before full cure, Santa Ana wind-driven rain stripping uncured joints, and base settlement creating voids that sand falls into. We see all three in Irvine, often in combination. Our fix addresses the root cause - regrading drainage, resetting edge restraint, or adjusting irrigation timing - not just sweeping in new sand.
We do when the project involves slab penetration for drainage, lighting, or structural connection, just as we do for Irvine Bathroom Remodeling projects that require plumbing rough-ins. Irvine’s older villages - Woodbridge, University Park, Northwood Pointe - sit on post-tension concrete slabs with tensioning cables that can be live decades after pouring. We request original cable layout drawings from the Irvine Company’s construction archive before any slab cutting, because severing a cable causes catastrophic structural failure and voids contractor liability coverage. This step adds time but eliminates risk. Call (657) 227-2502 to discuss your specific site conditions.
