AfterUnilock Construction in Austin, CA | Rowan Construction Group
Unilock construction service in Austin means matching the right paver line to your side of the Balcones Escarpment, because the limestone west and the clay east demand different base specs, edge restraints, and joint materials. We’re Rowan Construction Group, an independent Unilock service provider (not manufacturer-affiliated or authorized), and we’ve installed and repaired Unilock pavers and walls across Austin since 2007. On a Travis Heights patio that had settled a foot into fat clay, our crew excavated down 10 inches, laid geogrid and compacted limestone, and relayed the Courtstone dead level. Call (470) 298-9650 for a free estimate on your Fence Installation in Austin or Unilock project.
Why Austin Residents Choose Us for Unilock Service
The crews we send to your Austin property work with Unilock lines daily: Brussels Block for patios, Courtstone for pool decks and walkways, Mattoni for driveways, and Richcliff for retaining walls. That matters because each model behaves differently on the two Austins. West of MoPac, where caliche sits under everything, Mattoni needs a deeper compacted base than a tract-home installer might give it. East of I-35, where Vertisol clay swells and shrinks with every drought cycle, Brussels Block edges sink if the restraint isn’t sized for heave. We stock OEM Unilock color-matched repair units for patios and walls under 10 years old, and for structural problems we recommend a full lift-and-relay rather than patching. Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College and has spent two decades on residential and light commercial projects, the kind where the finished work looks like it was always supposed to be there. We carry that discipline into every Austin paver job.
Common Unilock Construction Problems We Solve in Austin
- Brussels Block patio edges sinking at the paver-wall junction. East Austin’s expansive black clay shrinks during multi-year droughts, pulling soil away from edge restraints that were undersized to begin with. The edge dips, the wall separates, and water gets under the base. We excavate, install proper edge restraint, and relay the border with compacted crushed limestone.
- Courtstone units spalling at corners after a hard freeze. Winter Storm Uri in February 2021 exposed how many Austin patios were laid tight-jointed with no sand cushion. When ice forms in the joint, the paver corners pop. We relay with a 1-inch sand setting bed and leave room for thermal movement.
- Mattoni driveway courses heaving on west Austin limestone lots. Where the base was laid over poorly compacted caliche fill, the pavers shift under car weight and create trip hazards. The fix is rarely a patch: we pull the course, recompact the subbase, and relay with proper slope.
- Richcliff retaining walls leaning after heavy rain events. When perforated drain pipe behind the wall is missing or clogged, water pressure pushes the face outward. We rebuild the wall, install the pipe at the right invert, and backfill with clean aggregate.
- Patios over existing concrete slabs that crack through the pavers. Austin’s clay moves, and a cracked slab underneath transfers movement up through the Unilock units. We assess whether a slab overlay or full removal and base rebuild makes sense for your site.
BeforeAfterUnilock Service in Austin: What Local Conditions Mean for Your Equipment
Every Unilock patio or driveway in central Austin’s Brentwood or Travis Heights must be designed around the city’s Heritage Tree ordinance, which requires a permit and mitigation payment to remove any tree 19 inches or greater in diameter. Protected live oaks grow all through these 1950s ranch-home neighborhoods, and their root zones extend well past the drip line. Our crews regularly reroute paver borders and reduce square footage to keep a patio out of a heritage oak’s critical root zone. That’s a design constraint our clients in Round Rock or Cedar Park, where the ordinance doesn’t apply, never face. It adds design time and sometimes thousands of dollars to a project. We pull the tree survey before we ever order the pavers, because finding a 24-inch live oak after the base is dug is how budgets and schedules go sideways. When you call us for Unilock service in Austin, the first question we ask is what’s growing on your lot.
Unilock Models & Products We Service in Austin
We service and install the Unilock lines most common in Austin landscapes: Brussels Block for its traditional tumbled look, Courtstone for a cleaner contemporary edge, Mattoni for driveways that need to hold car weight, and Richcliff for walls and steps. For parts, we use OEM Unilock color-matched units for repairs on patios and walls under 10 years old. For structural failures, we don’t mix new pavers into a failing base; we recommend a full lift-and-relay so the paver wear and the base movement stop fighting each other. On Austin’s clay soils, aftermarket polymeric sand like Gator Maxx is our standard joint material because it flexes with the ground rather than cracking. We stock base materials and edge restraints for both sides of the escarpment, so turnaround on an Austin repair doesn’t wait on a truck from Dallas.

FAQs - Unilock Construction in Austin
East Austin’s Vertisol clay shrinks during drought cycles and heaves when it gets wet, which pulls the soil away from edge restraints and lets the border pavers drop. If the restraint was undersized or omitted, the edge separates and water gets under the base. The fix is excavation, proper restraint, and a compacted limestone base that doesn’t move with the clay. Call (470) 298-9650 for a written assessment.
We can, but on Austin’s moving clay we usually advise against it. A slab that’s already cracked will transfer movement up through the pavers, and you’ll see the same crack pattern reappear in your Brussels Block within a season or two. Full removal and a proper base rebuild costs more up front but stops the problem at the source. We’ll show you both options in writing.
Unilock pavers have a textured surface that performs well when wet, better than smooth concrete or glazed tile. Austin’s flash-flood rain events, especially in the spring and fall, can leave standing water on patios with poor slope. We set paver patios at a minimum 1% slope away from the foundation so water drains instead of pooling. Call (470) 298-9650 and we’ll check your current patio’s drainage while we’re there.
Yes, if the pavers are the same lot and color and the original patio is stable. We don’t mix old and new Unilock units on the same surface because color variation and wear differences will show. If your leftover Courtstone or Brussels Block is clean and uncracked, we can extend the patio with a properly prepped base. The quote will tell you whether reuse saves enough to justify it.
During a kitchen remodel, mortar, grout, paint, and oil can stain Unilock pavers if they’re not protected. We lay heavy-duty drop cloths and plywood staging over paver surfaces before any demolition or trades work begins, and we seal vulnerable areas with a breathable paver sealer if the remodel runs long. If a stain does happen, we clean with a paver-safe product rather than acid or pressure-washing that can etch the surface. Call (470) 298-9650 to fold paver protection into your remodel scope.
