AfterUnilock Construction in Irvine, CA | Rowan Construction Group
We’re Rowan Construction Group, and we install, repair, and replace Unilock paver systems across Irvine. We’re an independent contractor, not a Unilock dealer or factory affiliate, and we’ve been doing this since 2007. What makes our Unilock work different in Irvine specifically: we understand the dual-permit reality, the village-level Architectural Review Committees, and the WUI fire codes that apply to homes in Quail Hill, Shady Canyon, Orchard Hills, and Portola Springs. Call (470) 298-9650 for a written estimate before anyone picks up a tool.
Why Irvine Residents Choose Us for Unilock Service
Grant Rowan founded this company after training in construction technology at Los Angeles Trade-Technical College, where the coursework covered concrete, framing, and estimating before he ever took a paying job. That early discipline shaped how we work now: we put the number in writing, we document what we find, and we don’t proceed on any change until the change order is signed. Under Clause 1 of The Haven Standard, that’s not optional, it’s the entire point. For Unilock work in Irvine, we bring experience with Richcliff pavers, Umbriano pavers, Lineo Dimensional Stone, and Estate Wall systems, and we’ve installed them in enough Irvine villages to know which CC&Rs will restrict paver color and which won’t. We use genuine Unilock pavers and wall blocks for color-matched additions, but we specify high-quality aftermarket geotextiles and permeable base materials where the job calls for better drainage performance than factory-standard bedding. Background-checked, uniformed crews. A documented photo record on every visit, included as standard. And a live person answers the phone 24/7.
Common Unilock Construction Problems We Solve in Irvine
- Rutting and uneven settling in driveways. Irvine sits on decomposed granite subgrades. When a previous installer skimped on GAP (graded aggregate base) depth to cut costs, the pavers settle unevenly within a few seasons. We excavate, recompact, and rebuild the base to the depth the location actually requires.
- Efflorescence and color fading on south-facing patios. Irvine’s intense sun and low annual rainfall, roughly 12 to 13 inches, pull mineral salts to the surface of tinted concrete pavers. The white haze is efflorescence. We clean it correctly and apply a breathable sealer where appropriate, and we’ll tell you honestly when a paver has simply faded past the point of restoration.
- Joint sand loss and weed sprouting near property lines. HOA common-wall setbacks in attached units get chronic irrigation overspray. That water flushes polymeric sand from the joints. We re-sand with the right product and recommend drainage adjustments so the problem doesn’t return in six months.
- Spalling at paver edges near downspouts. Even in Irvine’s mild winters, concentrated runoff from a downspout can cause freeze-thaw cycling at the edge of a patio. The fix is drainage redirection, not just paver replacement, which is the part most contractors skip.
- Mismatched patch jobs from the 1990s. Older Irvine tracts have Unilock pavers that are no longer in current production. We source compatible lines or salvage and re-lay original pavers where possible, and we’ll tell you before we start whether a true color match is achievable.
BeforeAfterUnilock Service in Irvine: What Local Conditions Mean for Your Equipment
Irvine is one of America’s largest master-planned communities, and the Irvine Company still exerts substantial control through village-specific CC&Rs. That means an Unilock driveway or patio addition in Woodbridge or Northwood requires two separate approvals: the City of Irvine building permit with its grading and erosion check, and the village Architectural Review Committee’s sign-off on paver color, pattern, and permeability. Skip the ARC submission and you can receive a stop-work order even with a valid city permit in hand. The city’s inspectors will not sign off on final occupancy if HOA approval was never obtained. Contractors from Anaheim or Unilock repair in Santa Ana routinely underestimate this because they work in cities where a building permit is the only gate. We don’t make that mistake, and we make sure the paperwork is approved before the first paver comes off the pallet.
Unilock Models & Products We Service in Irvine
We install and repair the full range of Unilock residential systems: Unilock sales & service work we handle includes Richcliff pavers for driveways and walkways, Umbriano for larger-format patio applications, Lineo Dimensional Stone for clean contemporary lines, and Estate Wall for retaining and seat walls. For color-matched additions, we use genuine Unilock pavers and blocks. For edge restraints, filter fabric, and bedding sand, we specify aftermarket geotextiles and permeable base materials that meet Irvine’s WUI and HOA drainage standards. When a paver shows deep structural cracks or base failure, we advise targeted excavation and recompaction rather than piecemeal patchwork, because the base is the part that fails first.

FAQs - Unilock Construction in Irvine
Yes, in most Irvine villages you need both a City of Irvine building permit and approval from your village’s Architectural Review Committee before installing or significantly expanding a paver driveway. The ARC approval is a separate legal requirement baked into your deed. If you skip it, you can get a stop-work order even with a valid city permit. We handle both submissions as part of our scope. Call (470) 298-9650 and we’ll walk you through exactly what your village requires.
It can. Homes in Quail Hill, Shady Canyon, and Orchard Hills that back up to open scrubland fall under California’s Wildland-Urban Interface fire codes. Those codes govern ignition-resistant construction assemblies, Class A roofing, and ember-resistant venting, and they can also restrict your hardscape choices. In some areas, permeable paver systems are required to manage runoff without creating fire-safe problems. We specify pavers and base materials that satisfy both your HOA and the WUI code.
Sometimes, and we’ll tell you honestly before you spend money. Unilock has shifted production lines over the decades, so an exact color match for a 1990s paver is not always possible. We first check whether a current production line is visually compatible. If not, we look at salvage options or propose a deliberate contrast design that reads as intentional rather than mismatched. The honest answer is always free. Call (470) 298-9650.
Rutting almost always comes back to the base, not the paver. Irvine’s decomposed granite subgrade is unforgiving when the GAP layer was skimped. If the base wasn’t excavated and compacted to the right depth, vehicle weight pushes the pavers down into the subgrade and you get two wheel-track ruts. The fix is excavation, recompaction, and proper base depth, then re-laying the pavers. Patchwork won’t hold. Call (470) 298-9650 for a written assessment.
Yes, a paver patio changes your site’s drainage characteristics, and Irvine’s grading checks treat that seriously. If your patio creates runoff toward a structure or a neighbor’s property, the city or your HOA may require a permeable system or additional drainage. We design the base and jointing to manage water correctly from the start, and we document everything so your permit inspection goes cleanly. Call (470) 298-9650 for a free estimate that covers drainage as part of the scope.
