AfterUnilock Construction in Dallas, CA | Rowan Construction Group
We provide independent Unilock in Irving and across Dallas with paver installation and repair, and the one thing that separates our work here from anywhere else is the ground itself. Blackland Prairie clay moves 3 to 4 inches every season, and a Unilock patio or driveway built without accounting for that movement will fail within two wet-dry cycles. If you need honest repair-versus-replace advice on Unilock pavers in Dallas, call (470) 298-9650 for a free estimate with a written price before any work starts.
Why Dallas Residents Choose Us for Unilock Service
Our crews work on Dallas Driveway & Pavers projects, including Unilock patios and walkways across the city’s shifting clay, and we know exactly how to build bases that won’t fail when the ground beneath them heaves and shrinks. We are an independent Unilock service provider, not authorized by Unilock, and that independence lets us recommend the right fix rather than the manufacturer’s preferred product every time. Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College and has spent two decades on residential projects where the difference between a lasting install and a callback was the prep work nobody sees. In Dallas, that prep work is everything. We carry genuine Unilock pavers for color and size matching on existing installations, and we stock quality aftermarket options when a full rebuild makes more sense than chasing a discontinued line. Our crews are background-checked and uniformed, and every visit includes a documented photo record so you can see what we found under the pavers before we put them back.
Common Unilock Construction Problems We Solve in Dallas
- Edge settlement and wave-like depressions. Dallas contractors who skip deep compaction on clay subgrades leave Unilock pavers rocking within the first year. We see this constantly in East Dallas and Oak Cliff, where the original installs used 3 to 4 inches of sand over raw clay and the pavers now show visible swales after two wet-dry cycles.
- Efflorescence and chalky color fading. Prolonged 100-degree-plus summers beat on older Unilock patios until the surface looks unevenly patched. Flippers in Lake Highlands and the M Streets often power-wash and reseal with the wrong product, which locks in the chalky look instead of fixing it.
- Driveway border rows spreading outward. Unilock driveway pavers shift and crack when trucks or construction vehicles drive over edges that lack proper concrete edge restraints bedded on Dallas’s expansive clay. The border rows spread, then the interior pavers follow.
- Weeds and ant colonies pushing pavers up from below. Dallas’s freeze-thaw cycles and heavy Gulf rain events break down polymeric sand joints faster than homeowners expect. Once the joints fail, weeds and ant colonies lift individual Unilock pavers, creating a bumpy, uneven surface.
- Hail chipping on paver steps and caps. Dallas sits in Hail Alley, and large Unilock paver steps and caps get chipped and spalled by hailstones, especially on older installations where the concrete mix was more porous. This is a real failure mode here, not a theoretical one.
BeforeAfterUnilock Service in Dallas: What Local Conditions Mean for Your Pavers
Dallas sits on Blackland Prairie clay that can heave and shrink 3 to 4 inches seasonally, so any Unilock paver project here needs a compacted aggregate base at least 8 to 10 inches deep with geotextile fabric underneath. That standard would be overkill on Austin’s limestone bedrock, but in Dallas it is the floor, not the ceiling. Our crew rebuilt a 20-year-old Unilock Brussels Block patio in Lakewood where the original installer had used only 3 inches of sand over the clay. The pavers had sunk 2 inches at the center and the edge restraints had disappeared entirely. We lifted every paver, excavated to 10 inches, installed geotextile and compacted crushed concrete base, then relaid the original Brussels Blocks after cleaning them, using new genuine Unilock edge restraints and polymeric sand. One year later, after a summer of 105-degree heat and a 6-inch October rain, the patio is flat and solid. That is what the Blackland Prairie demands, and that is what we build for.
Unilock Models & Products We Service in Dallas
We work on Unilock Brussels Block, Courtstone, Richcliff, and Town Hall lines across Dallas. When matching an existing installation matters for color and size, we source genuine Unilock pavers so the repair blends rather than patches. For full replacements, we often recommend quality aftermarket pavers with similar dimensions and a better warranty for Dallas’s clay conditions. Honest stance: if more than 25 percent of the base has failed, we recommend a full lift, re-grade, and rebuild rather than piecemeal patching that repeats the same cycle. For broader context on Unilock sales & service, our approach is the same whether the job is a repair or a new install.
Unilock Service Pricing in Dallas
Here are the line-item ranges we quote for Unilock work in Dallas. These are flat written prices, not estimates that drift once the crew arrives.

What drives the cost in Dallas is the base depth. An 8-to-10-inch compacted aggregate base with geotextile costs more than a thin sand bed, but it is the difference between a patio that lasts and one that sinks. Every quote includes a written scope and a written warranty. Call (470) 298-9650 for a free estimate with the number in writing before anyone picks up a tool.

FAQs - Unilock Construction in Dallas
Because the original installer treated Dallas clay like stable soil. Blackland Prairie clay heaves and shrinks 3 to 4 inches seasonally, and a base of 3 to 4 inches of sand over raw clay cannot resist that movement. The pavers look fine for a few months, then the first wet-dry cycle pulls the base apart and the surface develops waves and settlement. The fix is a full rebuild with 8 to 10 inches of compacted aggregate and geotextile fabric. Call (470) 298-9650 and we’ll give you a written price before any work starts.
In most cases, yes. Unilock Brussels Block and similar lines are dense enough to survive lifting, cleaning, and relaying. We reuse sound pavers whenever the base failure is the problem rather than the paver itself. If the pavers are cracked, spalled from hail, or too faded to match, we’ll tell you honestly which ones need replacing and which don’t. The decision shows up in the written quote, not as a surprise mid-project.
It does, especially on older installations where the concrete mix was more porous. Hailstones in Dallas storms chip and spall large Unilock paver steps and caps, leaving rough edges and exposed aggregate. Newer Unilock lines hold up better, but no paver is immune to a direct hit from Hail Alley. If your patio or steps show fresh chipping after a storm, we can assess whether the damage is cosmetic or structural. Call (470) 298-9650 for an exact quote, estimates are free.
A poured concrete edge restraint, bedded below the paver border and anchored beyond the clay’s movement zone. Without it, the border rows spread outward under vehicle weight and the entire driveway loses its lock. We use concrete edge restraints on every Unilock driveway in Dallas, regardless of the paver line. The cost is a line item in the written estimate, not an add-on later.
The answer is joint stabilization that survives Dallas weather. We use polymeric sand with a higher binding resin content than what most installers buy, and we re-compact the joints after installation and again after the first heavy rain. When joints stay sealed, weeds and ant colonies have no entry point. If an older patio already has failing joints, we clean out the old sand, treat the ant colonies, and re-sand before re-compacting. Call (470) 298-9650 and we’ll put the fix in writing.
