Unilock Construction in Dallas, CA | Barrett & Sons Construction
Barrett & Sons Construction provides independent Unilock in Irving and across Dallas for paver installation, repair, and replacement. We are not a factory store or manufacturer affiliate, and we don’t pretend to be. What we are is a local crew that has pulled up, re-based, and re-set more Unilock patio and driveway pavers on this city’s black gumbo clay than we can count. The thing that makes our Unilock work different here comes down to one word: base. Get the base wrong on Dallas clay and the prettiest Brussels Block patio on the street will look like a washboard in two seasons. Call (877) 610-1318 and we’ll tell you what your project actually needs, before anyone picks up a shovel.
Why Dallas Residents Choose Us for Unilock Service
Tom Barrett founded this company in 1998, and his sons run crews most days. Tom learned his trade at Los Angeles Trade-Technical College, starting with framing and finishing with enough hours in the field to know the job never lies. We have been installing premium hardscape brands, including Unilock, across the local area for over 29 years. Homeowners in Dallas pick us because we answer our own phone, show up when we say we will, and put every scope and allowance in writing before a single paver moves. We are an independent Unilock service provider. That means when your Unilock sales & service need comes up, we can recommend what’s actually right for your Dallas lot, not what a corporate catalog tells us to push this quarter.
We stand behind the work with our written 90-Day Done Right Promise. If something’s not done right, Tom comes back and makes it right, one call. That’s not a slogan. It’s on every contract.
Common Unilock Construction Problems We Solve in Dallas
- Edge restraint failure from clay heave. Dallas’s expansive black gumbo swells and shrinks inches seasonally. Without a concrete edge restraint tied into a proper base, perimeter Unilock pavers spread outward and lose interlock. We see this on patios all over Oak Cliff and Kessler Park.
- Settling and lippage in Unilock driveways. The moisture cycles here create voids under the bedding layer. Pavers then dip and create trip lips. A 20-year-old Unilock driveway in 75204 with visible edge spreading usually has exactly this failure underneath.
- Efflorescence and surface spalling on Brussels Block. Dallas hard water irrigation combined with repeated wet-dry cycles pulls salts up through lighter Unilock units. The white chalky residue is efflorescence; the flaking surface is spalling. Both are common on older Brussels Block patios.
- Joint sand washout on sloped lots. Intense North Texas storm events sheet water across Oak Cliff lots with real grade. Unilock jointing sand washes out fast, leaving pavers loose. We replace it with Unilock brand polymeric sand that locks up after setting.
- Patio heaving at the foundation corner. A dry summer shrinks the clay, then October rains resaturate it just as fast. The soil swells at different rates next to a house foundation, which is exactly where Unilock patios often lift and separate.
Unilock Service in Dallas: What Local Conditions Mean for Your Work
Dallas sits directly over the Woodbine aquifer recharge zone, and that matters for paver work more than people realize. The aquifer influence amplifies the black gumbo soil’s swelling cycle. In 2023, drought-driven clay shrink drove more foundation calls in Dallas than in any other Texas metro, and that same shrink translates straight to Unilock paver heaving and edge separation. A patio in Dallas doesn’t move like a patio in Austin or Fort Worth. It moves harder, faster, and in two directions seasonally. Our crew pulled up to a 1940s craftsman in Kessler Park, 75208, where a Unilock Beacon Hill Flagstone patio had opened a 2-inch lip at the house foundation corner after a dry summer followed by October rains. We lifted the affected pavers, re-compacted a full 12-inch crushed limestone base with geotextile over the shifting clay, re-set with new Unilock jointing sand, and added a concrete edge restraint. Nine months later that paver surface is still table-flat while the neighbor’s un-restrained patio has buckled. That’s the difference between doing Unilock work in Dallas and doing it almost anywhere else.
Unilock Models & Products We Service in Dallas
We install, repair, and replace the full range of Unilock residential lines, including Brussels Block, Beacon Hill Flagstone, Courtstone, and Lineo Dimensional Stone. For replacement work we source genuine Unilock pavers and Unilock brand polymeric sands so new units match the existing color and texture as closely as every job allows. When an older line has been discontinued and genuine units are not available, we use industry-verified bedding and edge materials from Dallas suppliers rather than pretending a mismatch is a match. Our crews keep common jointing sand and edge restraints stocked locally so most Dallas service area repairs move fast. If paver damage runs beyond 20% of the surface area, or the clay has caused repeated structural failure, we’ll say it plainly: a full base re-compaction and re-install will outlast a patch job nearly every time.
Unilock Service Pricing in Dallas
Pricing on Unilock work in Dallas depends on the base more than the pavers. If we’re installing over clay that has never moved, the job costs less. If we’re repairing heave damage or rebuilding a base that failed, the job costs more. Here are the current line-item ranges for the Unilock work we do most often in Dallas:
| Service | Price Range |
|---|---|
| Paver Patio Installation | $3,500 - $11,000 |
| Paver Driveway Installation | $7,000 - $18,000 |
| Driveway Replacement | $5,000 - $14,000 |
Every free estimate includes a written line-item scope. No allowances that are not on paper, no change orders that appear after the fact. Call (877) 610-1318 and we’ll walk the site and give you numbers you can actually work from.

FAQs - Unilock Construction in Dallas
Yes. Dallas clay swells and shrinks more aggressively than most Texas soils, so the base has to be deeper, better compacted, and separated from the clay with geotextile. A standard 4-inch base that works in parts of Austin will not hold in Dallas. We use a full 12-inch crushed limestone base with geotextile and concrete edge restraint on Dallas Unilock patios and driveways because anything less fails on this soil. Call (877) 610-1318 for an exact base recommendation on your lot.
Yes, as long as the Beacon Hill Flagstone color is still in production or available through our supplier network. We source genuine Unilock units first and match color and texture before removing anything. If your specific color has been discontinued, we’ll tell you before we start and show you the closest available option. No surprises.
Yes, and this is a Dallas-specific hazard most cities don’t face. Post-tensioned slabs contain high-tension steel cables that are catastrophically dangerous if cut. Before any saw-cutting around your foundation for paver work, we locate and mark the cables. This is not a DIY step. It’s a trained-professional step, and we do it on every Dallas job near a post-tension slab.
Because Dallas sits on expansive black gumbo clay over the Woodbine aquifer recharge zone. Summer drought shrinks the clay and creates voids under the bedding layer. Winter and spring rains resaturate the clay and it swells, lifting pavers at different rates. The fix is a proper 12-inch base with geotextile and concrete edge restraint, which we install on every Unilock job in Dallas. Call (877) 610-1318 for a free look at your patio.
If the edges are spreading, the base has likely failed or was never built for Dallas clay. At 20 years old with visible movement, a full base re-compaction and re-install will outlast any patch job. We’ll tell you straight what the numbers look like for both options and let you decide with the full scope in writing. Estimates are free, and the number is (877) 610-1318.
