Unilock Construction in Round Rock, TX | Mason Remodeling Co Austin
Unilock construction service in Round Rock typically costs $3,500 to $18,000 depending on whether you’re installing a patio or driveway, and most paver repairs can be completed in one to three days. We’re Mason Remodeling Co Austin, a General Contractor in Round Rock, and we install and repair Unilock pavers on over 40 Round Rock area projects a year. The one thing that makes our work here different: we know how Round Rock’s blackland clay and the city’s own base-code requirements shorten the life of paver installations built by crews that treated this soil like it was anywhere else. Call (903) 623-1966 for a free estimate, and we’ll tell you straight what your Unilock project actually needs.
Why Round Rock Residents Choose Us for Unilock Service

Most contractors in Round Rock can lay pavers. Far fewer can tell you why your Unilock Brussels Block patio is lipping after three summers, or why the polymeric sand keeps washing out of your Courtstone driveway after every thunderstorm. That’s where we come in.
Our crews handle the full Unilock product line daily, from Brussels Block and Beacon Hill Flagstone to Courtstone and Richcliff. We’re not a factory-authorized dealer, and we won’t pretend to be. What we are is a local crew that has seen how Unilock modular systems behave in central Texas soil, under central Texas sun, through central Texas rain. Isaac Pruett, our owner, learned construction at Los Angeles Trade-Technical College and spent years on residential and commercial work before bringing that hands-on experience to Austin and Round Rock. He’s the kind of builder who wants to know what’s failing and why, not just patch the surface and move on.
We also show up the way homeowners here expect. Every technician is background-checked and identity-verified under the Threshold Standard. You get a name and photo before the visit, and a photo ID badge at the door. Written pricing before any work starts. A written guarantee on every project. And a 365-Day Done Right Promise: if the work isn’t right within a year, we make it right at no cost to you.

Common Unilock Construction Problems We Solve in Round Rock
- Paver sinking and heaving from blackland clay. Round Rock sits on expansive clay that swells when wet and shrinks when dry. That movement pushes against poorly compacted bases, causing individual Unilock pavers to sink, tilt, or heave until you’ve got lippage and a trip hazard on your patio or walkway. We lift the affected area, re-compact the base properly, and reset the same Unilock units.
- Edge restraint failure in summer heat. The plastic edging used on many Round Rock paver jobs curls and distorts under prolonged Texas heat. Once the edge fails, perimeter pavers spread outward, joints open up, and weeds move in. We replace failed plastic edging with rigid aluminum or concrete restraint and re-secure the perimeter.
- Efflorescence on darker Unilock units. Richcliff and Courtstone pavers show white mineral haze more readily than lighter colors, especially after Round Rock’s heavy rain cycles pull minerals up through the paver. This isn’t a product defect, it’s moisture chemistry. We clean the surface and address the drainage issue that’s feeding it, so the haze doesn’t return in six months.
- Polymeric sand washout after sudden downpours. Round Rock storms drop water fast, and if the base underneath your Unilock patio or driveway wasn’t sloped to code, that water channels through joints and strips the polymeric sand out. We re-slope the base where needed, then re-sand and compact the joints so they stay put.
- Pre-2018 Teravista installs with inadequate compaction. Homes built in Teravista before 2018 often have paver bases that were never compacted to the depth Round Rock code now requires. We see it all the time. The fix is a full re-base, not a cosmetic re-level, and we’ll walk you through the difference before you spend a dollar.
Unilock Service in Round Rock: What Local Conditions Mean for Your Equipment
Here’s something most Round Rock homeowners don’t learn until a patio goes bad: the city’s current code requires an 18-inch-deep compacted limestone base for paver driveways in new subdivisions. But during the 2020 to 2022 building boom, when crews were stretched thin and inspectors were buried, many homes were built with 12-inch bases. That six-inch difference isn’t a technicality. On expansive clay, a 12-inch base gives the soil enough leverage to move your pavers within a few seasons. So when we give a repair estimate on a newer Round Rock home, it often includes a re-base before we lay a single new Unilock unit. You can’t fix a paver problem by ignoring what’s underneath it. In neighborhoods like Teravista and Mayfield Ranch, where homes went up fast during that window, we’re now seeing the predictable result: patios and driveways that looked fine at close, showing lippage and joint washout two or three years later. The pavers aren’t failing. The base was never right.
Unilock Models & Products We Service in Round Rock
We install and repair the Unilock product lines Round Rock homeowners actually use: Brussels Block, Beacon Hill Flagstone, Courtstone, and Richcliff. That covers everything from large-format flagstone patios to classic tumbled driveways and clean-lined modern walkways.
For matching and additions, we use genuine Unilock pavers and edge restraints, so new sections blend with existing work. For underlayment, we substitute locally sourced crushed limestone and woven geotextile rated for clay soil. That’s not a downgrade, it’s an upgrade. A locally sourced base compacted to Round Rock code performs better than what many original installs used, especially on this soil. On repair jobs, we replace damaged units with the same product line and only recommend a full re-base when the original was built without proper compaction. If you’d like to see our broader Unilock work, we also provide Unilock sales & service across the region.
Our crew just finished lifting and re-setting 600 square feet of large-format Beacon Hill Flagstone at a home on Rusk Lane in Teravista. The original 2019 install had no geotextile and sat on 10 inches of loose sand. After June storms, half the patio had settled over an inch. We pulled the pavers, compacted an 18-inch base of crushed limestone per Round Rock code, and relaid with fresh Unilock joint sand. The new surface is flat and drains clean to the street.

FAQs – Unilock Construction in Round Rock
It’s almost always a soil and base problem, not a paver problem. Round Rock’s expansive blackland clay swells and shrinks with moisture, which moves any base that wasn’t compacted deep enough or built with proper geotextile. The Unilock pavers themselves are just riding on what’s underneath. We fix the base, not just the surface. Call (903) 623-1966 and we’ll assess what’s actually moving.
Yes. We use genuine Unilock pavers from the same product line, so replacement units match in dimension and finish. Color variation is normal with concrete pavers, but we source from the same product family and blend units for a close visual match. If your original was installed years ago, some natural weathering difference will remain, but it’s far less noticeable than a cracked paver or a mismatched patch.
Heat doesn’t hurt cured polymeric sand, but sudden downpours do, especially when the base underneath wasn’t sloped to drain properly. Water channels through the joints and washes the sand out, leaving gaps that weeds love. We re-slope the base where needed and use fresh Unilock joint sand so the joints hold through Round Rock’s storm season.
No, that’s efflorescence, and it’s removable. It happens when minerals in the paver or the base migrate to the surface as moisture evaporates. Round Rock’s rain-sun cycles make it more visible, especially on darker units like Courtstone and Richcliff. We clean the surface and address the drainage that keeps feeding moisture through the pavers, so it doesn’t come right back. Call (903) 623-1966 for a cleaning assessment.
It typically does, especially in communities like Teravista and Mayfield Ranch where curb consistency matters to buyers. A properly installed Unilock driveway with a code-compliant base reads as a durable upgrade, not a future liability. The key is installation depth and drainage. If the base is right, our Bathroom Remodeling in Round Rock approach ensures the driveway looks great and appraises well. If it isn’t, you’ll be repairing it before you sell. We build them right the first time.
