Why San Antonio Homeowners Choose Unilock Construction
We provide San Antonio Unilock service for construction, repair, and installation across the area, from paver driveways and patios to U-Cara retaining walls. Our crews have lifted, cleaned, and reinstalled Unilock pavers on hundreds of San Antonio properties, and we understand exactly how EnduraColor and Series products behave in our clay soil, hard water, and 300-plus days of annual sun. Mason Remodeling Co San Antonio is an independent Unilock service provider, not a factory-authorized dealer, which means our recommendations are driven by what actually works on San Antonio ground, not a corporate script. Call (254) 269-5071 for a free estimate.
What separates our Unilock work from a general hardscape crew is simple: we have seen what San Antonio does to these pavers over a decade, and we fix the base, not just the surface.
Why Trust Mason Remodeling Co San Antonio for Your Unilock Construction?
Our technicians work with Unilock Brussels Block, Richcliff, Beacon Hill Flagstone, and U-Cara systems week in and week out, and that repetition means we know what a failing paver base feels like under a probe before we ever lift a unit. Isaac Pruett, our owner, learned construction fundamentals at Los Angeles Trade-Technical College and has spent two decades on job sites across the Southwest. He and our crew have been working San Antonio jobs for years, from gut renovations near the King William Historic District to quiet kitchen rebuilds in neighborhoods across the city.
Unilock pavers are a spec-grade product, but they are only as good as the base beneath them. San Antonio’s expansive clay shrinks in summer drought and swells after storms, and that movement will expose any shortcut in sub-base preparation within two or three seasons. Because we also handle General Contractor services and whole-home remodels, we approach Unilock installations with a builder’s eye: we check drainage, we check the soil, and we tell you what we find before we quote. Every project gets a written price before any work starts, and every crew member who arrives at your door is background-checked, uniformed, and introduced by name and photo before the visit under The Threshold Standard.
Know who’s coming, know what it costs, know it’s covered, that’s the whole job before the job starts.

Common Unilock Construction Problems We Fix in San Antonio
- Efflorescence on EnduraColor surfaces. San Antonio’s hard tap water and irrigation overspray leave mineral deposits that dry as a white haze on Unilock’s color-pop faces. On Richcliff walls and Brussels Block patios, this is not a manufacturing defect; it is our water chemistry meeting the paver’s surface. We clean it with non-acidic methods that remove the haze without dulling the finish.
- Paver shifting and edge rutting on Brussels Block driveways. Our expansive black clay contracts hard during summer droughts and swells after rain, and driveway edges take the worst of it. Brussels Block driveways that were installed without a geotextile base or proper Clearbit sub-base will start to migrate outward and sink at the edges. We see this most often on homes built in the 1970s through 1990s across the north and west sides of San Antonio.
- UV color fade on Beacon Hill Flagstone patios. San Antonio gets more than 300 days of intense sun per year, and older Beacon Hill Flagstone patios show it as a two-tone effect: areas under furniture stay rich while exposed sections wash out. This is not a product failure; it is UV doing what UV does to any pigmented concrete. We can repair or replace the faded units and apply a breathable sealer to even out the look.
- U-Cara wall panels loosening or tilting. The U-Cara Multi-Face Wall System relies on a properly compacted backfill, and on San Antonio hillside lots the rocky, coarse backfill material has to be installed in lifts. When it is not, panels loosen or lean as the soil settles. We excavate, re-compact in lifts, and reinstall the panels so the wall stands plumb.
- Joint sand washout after flash droughts. When San Antonio goes weeks without rain and then gets a sudden downpour, water moves fast across paver surfaces and strips joint sand. We re-sand with polymeric sand that sets and resists washout, and if the base has been compromised by repeated erosion, we lift and reinstall the affected section rather than hiding the problem with a quick re-sand.
Unilock Parts & Our Repair-vs-Replace Approach
We source genuine Unilock pavers and wall components from local distributors whenever color-match or warranty considerations matter. Unilock’s blends are specific, and a close-color aftermarket substitute will show itself within a season. For sand, sealers, and edging, we stock high-quality compatible aftermarket brands to keep costs controlled where the OEM name adds no performance value.
Our honest stance on repair versus replace comes down to the base. If the sub-base has failed, no amount of surface patching will hold. We lift and reinstall with proper Clearbit base and geotextile to prevent recurrence. If the problem is surface staining or minor joint washout, a cleaning and polymeric re-sand is the right fix, and we will not sell you a rebuild you do not need. Call (254) 269-5071 for an honest assessment.
Our Unilock Service Process – Step by Step
- 1
Diagnosis. We inspect the paver surface, probe the joints, check edging and drainage, and identify whether the base is sound or compromised. On U-Cara walls, we check for lean, bulging, and backfill settlement.
- 2
Repair or install. We lift only the affected area when possible, then reinstall with proper base material and joint sand. For new Unilock installations, we prep the sub-base, lay geotextile, and set pavers to manufacturer spacing.
- 3
Test. We run water across the surface to confirm drainage, check joint sand compaction, and verify edges are secure. On retaining walls, we confirm plumb and panel alignment.
- 4
Warranty. Every completed project is covered by a written guarantee with clearly stated terms. If a repair or installation fails within 365 days, we return at no charge, no dispute process, no conditions.

FAQs – Unilock Construction Service in San Antonio
Can Unilock Brussels Block pavers handle San Antonio’s hot summers without fading or becoming too hot to walk on?
Unilock Brussels Block pavers are not going to fade under San Antonio sun the way painted concrete does; the color runs through the paver body. As for heat, they absorb warmth like any concrete product, and darker blends will feel warmer on bare feet in July. A lighter color blend and a breathable siloxane sealer helps moderate surface temperature. Call (254) 269-5071 to talk through the right blend for your San Antonio patio or driveway.
Is efflorescence on my Unilock Richcliff retaining wall a defect?
No. Efflorescence is mineral salts from San Antonio’s hard water wicking to the surface of the paver and drying as a white haze. It is a cosmetic and environmental condition, not a manufacturing defect, and it will not harm the paver’s structural integrity. We remove it with non-acidic cleaners that do not etch or dull the EnduraColor finish. Call (254) 269-5071 and we will assess whether it is simple efflorescence or something else.
Can you repair just one sunken section of my Unilock paver driveway, or do I need to replace the whole thing?
In most San Antonio driveways, we can lift and reinstall the sunken section without touching the rest. The deciding factor is what the base looks like underneath. If the sub-base in that area has failed due to clay movement or poor original compaction, we rebuild that section with proper Clearbit base and geotextile. If the base is sound, the fix is faster and less expensive. Call (254) 269-5071 for a written quote.
What is the best way to clean Unilock pavers without damaging them?
Use a garden hose, a stiff-bristle brush, and a pH-neutral cleaner made for concrete pavers. Avoid muriatic acid and high-pressure washing; both can strip the surface color and open the paver to faster UV fade. We once saw a 15-year-old Beacon Hill Flagstone patio in Stone Oak where a pressure washer plus muriatic acid had stripped the color from two dozen pavers. We matched the faded blend with exact factory replacement pavers, cut out the damaged units, and finished with a breathable siloxane sealer to even the look.
Does Unilock’s U-Cara wall system work on a slope in San Antonio?
Yes, but the backfill preparation matters more than the panels themselves. San Antonio hillside lots have coarse, rocky soil that must be compacted in lifts behind the wall. When it is not, panels loosen and the wall leans. Our crews excavate, re-compact in lifts, and reinstall the panels properly. Call (254) 269-5071 to have us look at your slope and give you a straight answer.
