Unilock Construction in Garland, CA | Rowan Construction Group
We provide independent Unilock paver installation and repair across Garland, and the one thing that makes our work here different is this: we’ve spent nearly two decades watching how North Texas black clay moves under mid-century slab homes, and we spec every Unilock job around that movement. We’re not manufacturer-affiliated, but we know these pavers cold. If you’re pricing a paver driveway, patio, or a full teardown-and-rebuild, call (470) 298-9650 for a written line-item estimate before anyone picks up a tool.
Why Garland Residents Choose Us for Unilock Service
Grant Rowan founded this company in 2007 after training in construction technology at Los Angeles Trade-Technical College, where the coursework put framing, concrete, and estimating ahead of salesmanship. That discipline carries through on every Unilock job we take in Garland. We’re a local Unilock sales & service provider, not a factory-authorized shop, which means we can match OEM pavers when they make sense and recommend better base materials when they don’t.
What Garland homeowners get from us is a flat written price before work starts, a signed change order before any scope shifts, and a documented photo record of what we found and what we did. No call-for-a-quote runaround. No manufactured urgency. The estimate shows the paver line, the base depth, the edge restraint, and the labor number in black and white. Grant’s rule applies here the same as it does on a structural remodel: measure twice, say it once, show your work.
Common Unilock Construction Problems We Solve in Garland

- Edge settling along driveways and walkways. Garland sits on expansive black clay that shrinks hard during summer drought and heaves after spring rains. Unilock pavers near the edges of a driveway lose bedding support first, which is where you see the telltale 2- to 3-inch lip against the concrete apron.
- Joint sand washout in older patios. Low-lying central Garland lots have been shedding storm runoff across paver patios for decades. Once the poly sand washes out, the joints open, weeds get in, and the pavers start drifting out of plane.
- Hairline cracks and spalling from differential settlement. The slab homes that define Garland’s renovation market move unevenly. When a 1950s unreinforced slab shifts, any hardscaping attached to it shifts too. We regularly see Unilock units with hairline cracks that trace the foundation movement underneath.
- Root incursion through aging paver joints. Post-war lot trees in Garland have had 50 to 70 years to mature. When roots push under a paver patio, they lift units and crack the joint sand. Pulling the affected rows is the only fix that lasts.
- Failed base material under heavy use. Older Garland paver installations often sit on 2 to 3 inches of sand over raw clay. When the clay cycles, the sand migrates, and the pavers start rocking. We rebuild these with stabilized aggregate at the correct depth for this soil.

AfterUnilock Service in Garland: What Local Conditions Mean for Your Equipment
Here’s the part most Unilock pages won’t tell you. Garland has one of the highest concentrations of unreinforced 1950s slab homes in Dallas County. When you pull a permit for a paver driveway replacement in neighborhoods off Belt Line Road or around central Garland’s older subdivisions, the city inspector frequently wants documented proof of the slab’s condition before hardscaping can proceed. That’s because a paver installation is rarely just a paver installation here. We’ve seen a “simple” paver patio permit turn into a foundation documentation project because the existing slab had cracked and moved enough that the inspector needed to see what the hardscape would sit on. Mesquite and Richardson jobs don’t hit this wall at anything like the same rate. Garland’s specific clay subgrade makes foundation disclosure a near-standard part of hardscaping contracts here, and our crews document that condition in the written scope so the permit process doesn’t stall.
Unilock Models & Products We Service in Garland

We install and repair four Unilock lines that have a strong track record in North Texas: Brussels Block, Courtstone, Richcliff, and Thornbury. Brussels Block and Courtstone are the classic modular units you see on mid-century Garland walkways and driveways. Richcliff gives a longer, linear profile that works well on newer additions in north Garland. Thornbury is our go-to for patios where the homeowner wants a tumbled, older look without waiting 20 years for it.
For repairs, we use Unilock’s OEM pavers whenever a color match and fade profile require it. On full teardown-and-rebuild jobs on 50-year-old clay-heavy lots, Grant will often specify an aftermarket stabilized aggregate base combined with OEM paver units. That keeps the finished surface true to the original look while cutting waste and bringing the material cost down where it doesn’t affect performance.
Unilock Service Pricing in Garland
Here are the line-item ranges you should expect on a written Garland estimate:
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000-$18,000 |
| Paver Patio Installation | $3,500-$11,000 |
| Driveway Replacement | $5,000-$14,000 |
What drives the number: the base depth required for Garland’s clay, whether the existing slab needs documentation or remediation before the permit clears, and which Unilock line you choose. A Brussels Block driveway on a stable slab lands at the lower end. A full teardown-and-rebuild on a moving slab with a Thornbury surface runs higher. Every estimate includes the written scope, the paver line, the base spec, and the labor number. Call (470) 298-9650 for an exact quote on your project.

FAQs - Unilock Construction in Garland
Edge sinking is almost always a bedding failure where the clay shrank most during the drought and the edge restraint didn’t hold. The center of the patio has more paver weight and interlock keeping it stable; the edges have no adjacent units to buttress them. The fix is pulling the affected rows, rebuilding the edge with a deeper stabilized base, and reinstalling the original pavers. Call (470) 298-9650 and we’ll send a written quote for the repair.
If the cracks run through individual units but the base underneath is stable and the pavers aren’t rocking, a spot repair with OEM matching pavers can work. If the cracks trace a visible movement line in the slab or the driveway has a visible lip at the apron, the base has failed and spot repair will fail again within a season or two. We document the condition in the written scope so you know which situation you have before you spend anything.
On older central and south Garland lots with unreinforced 1950s slabs, yes, frequently. The inspector wants to know what the hardscape is going on top of, especially if the existing driveway shows cracking or out-of-level movement. Our crews document the slab condition as part of the pre-permit scope so you’re not surprised mid-project.
Courtstone and Richcliff both perform well on Garland clay when installed on a proper stabilized aggregate base at the right depth. The paver line matters less than the base underneath it. A quality base absorbs the movement cycles that would otherwise crack units or open joints. The paver choice is about the look; the base spec is about survival.
Hail and wind don’t break pavers directly, but they do accelerate joint deterioration by knocking loose debris into seams and stripping aging poly sand. After a significant hail event, we recommend checking joint sand levels and edge restraint before the next rain cycle. Call (470) 298-9650 and we’ll take a look. Estimates are always free.
