Why Austin Residents Choose Us for Unilock Service

Tom Barrett grew up in the San Fernando Valley watching crews pour foundations with his dad on weekends, then learned the trade properly at Los Angeles Trade-Technical College. He started Barrett & Sons in 1998, and today his sons run crews alongside him on Unilock jobs and Kitchen Remodeling - Austin projects across the city. We’re not a franchise and we don’t send strangers to your house. Our crews have torn out and rebuilt more Unilock paver installations across Austin than any independent outfit we’ve worked alongside, from drought-cracked Brussels Block driveways in Tarrytown to modular Unilock retaining walls bowing under black-gumbo hydrostatic pressure east of I-35. We know Unilock’s concrete chemistry and jointing systems well enough to match failures to the exact geology and heat that caused them, and we never claim to be a Unilock dealer or authorized agent. Just honest work by people who answer the phone.

For Austin homeowners who’ve been burned by a national company quoting one price on the phone and handing over a different bill at the door, our standing rules matter: every scope, every allowance, every price change arrives as a written change order before work happens. Permits pulled and inspections signed on every eligible job. And Tom’s name, address, and license number are published for anyone to look up.

Common Unilock Construction Problems We Solve in Austin

• Heaving and edge spalling on west-side driveways. West of I-35, Austin sits on dense limestone bedrock. Shallow-set sand under Unilock Brussels Block pavers shifts when summer downpours hit, causing edges to spall and ruts to form. We fix the joints, the base, or both, and the repair starts with understanding which side of the fault line you’re on.
• “Roller-coaster” patio waves east of I-35. On the Blackland Prairie’s expansive clay, freeze-dry cycles over two seasons swell and shrink the soil. Unilock patios develop a wave pattern, with polymeric sand joints popping up and individual pavers cracking. We see it constantly in Mueller and east Austin.
• Leaning Estate Wall units on sloped Travis Heights lots. Standard crushed stone bases don’t hold back clay that stores moisture. Unilock Estate Wall blocks set on slope lots begin to lean and open vertical gaps after one wet winter. We rebuild with proper drainage and geotextile.
• U-Cara Multi-Face panel separation. Austin’s 105°F direct summer UV and thermal cycling peel the tongue-and-groove seams on U-Cara panels, especially when installers didn’t leave enough expansion gap along steel edging. We reset and re-gap panels correctly.
• Polymeric sand washout after flash floods. Austin’s impervious Blackland Prairie soil sends water across Unilock joints instead of soaking in. In east-side neighborhoods like Mueller, polymeric sand rinses out fast, leaving loose pavers and weeds. We use a coarser jointing sand blend suited to Austin’s rainfall pattern, not the generic mix sold everywhere.

Unilock Service in Austin: What Local Conditions Mean for Your Equipment

Here’s the thing most contractors outside Austin never figure out. Austin straddles the Balcones Escarpment, and that fault line creates two completely different failure paths for Unilock pavers. West of I-35, bedrock lies shallow, so water doesn’t drain away, it pools under the pavers and heaves the joints. East of I-35, the black gumbo clay moves several inches vertically every wet-dry cycle, which is why properly compacted paver bases there need deep piers or geotextile separation, not just sand. The same Unilock Brussels Block driveway will fail differently on either side of I-35, and a repair that works in Tarrytown won’t hold in Mueller. We stage every Austin job around that geological divide, and it’s why our estimators walk the site before giving a number. The Austin service area page has more on where we work.

Unilock Service in Austin: What the Heritage Tree Ordinance Means

One more Austin-specific wrinkle that catches out-of-town contractors every time. The Heritage Tree Ordinance requires a certified arborist survey and city review before any ground disturbance within the critical root zone of protected trees, generally live oaks and other natives at 19+ inches in circumference. That means a Unilock paver driveway or patio in older neighborhoods like Westminster or Clarksville can’t just be trenched and compacted anywhere. Often the entire front yard is within one grand oak’s drip line, so our crews stage paver cuts and compactions around root flares instead of trenching into them. We’ve done it on 1950s lots where the oak was there before the house, and the permit process alone can stretch weeks. We fold that carrying cost into the estimate so you’re not surprised.

Unilock Models & Products We Service in Austin

We work on the full Unilock line, including Brussels Block, Estate Wall, Moda Series, and U-Cara Multi-Face. For repairs and additions, we use genuine Unilock pavers, wall units, and matching edge restraints whenever the product is still in production, because color lot matching across years is nearly impossible with aftermarket look-alikes. If a line is discontinued or you want to control budget, we source quality concrete-compatible substitutes from Texas quarries but disclose the color and curing mismatch upfront. We only recommend full removal and reinstall when base failure is systemic, not just surface wear. Same Unilock product in Unilock service in Fort Worth gets different treatment because the soil there isn’t Austin’s black gumbo.
