Unilock Construction in San Antonio, TX | Elmstead Remodeling San Antonio
We provide independent Unilock paver and wall installation and repair across San Antonio, from Alamo Heights to Terrell Hills and out toward Schertz and Fair Oaks Ranch. What makes our Unilock work here different is simple: we plan every hardscape around San Antonio’s shallow limestone ledges, clay-driven soil movement, and total lack of zoning. Those three local realities change how a paver driveway or patio should be built and repaired. If you’re researching Unilock construction service in San Antonio, call (432) 233-0976 and we’ll walk the site with you before quoting anything.
Why San Antonio Residents Choose Us for Unilock Service
Unilock pavers and walls are built well, but their long-term performance in San Antonio depends almost entirely on what sits beneath them. Our crews have spent years cutting through limestone shelf rock, compacting road base over expansive clay, and resetting pavers that shifted after a drought summer. Graham Stein, who leads our San Antonio team, learned the construction trade at Los Angeles Trade-Technical College and has spent decades framing, finishing, and fixing what matters most to homeowners. Around here, that means knowing when a settled paver is a Unilock issue and when it is the soil under the paver giving way. We stock genuine Unilock replacement units locally for faster turnaround and use quality aftermarket polymeric sand and base materials where they outperform the original. We are an independent Unilock service provider, not a manufacturer-authorized dealer, which means our loyalty is to the finished job on your property, not to a corporate program. We also offer full Unilock sales & service support, so a repair conversation can turn into a new installation plan without switching contractors.

Common Unilock Construction Problems We Solve in San Antonio
- Edge spalling on Estate Series pavers. When a limestone base settles unevenly during a San Antonio summer drought, the edge course takes point loads it was never meant to carry. Individual units crack or chip at the corners. We reset the base, re-compact, and replace only the damaged pavers with matching Unilock units.
- Clogged Eco-Promenade permeable joints. Caliche dust from nearby construction and San Antonio’s dry winds works into the permeable joints and blocks infiltration. You end up with surface ponding in a driveway that was supposed to drain through. We remove the old joint material, flush the system, and re-sand with a compatible aggregate that keeps water moving.
- Rivercrest wall units tipping outward. In neighborhoods like Alamo Heights, bedrock can sit a foot below the surface. When the footing soil shrinks around slab-on-grade homes, wall units lean. We dig back, rebuild the buried course, and add drainage so the wall does not lean again after the next rainy season.
- Polymeric sand erosion between Old Greenwich pavers. Sudden flash floods wash sand from the joints, leaving channels. Car tires then shift pavers. We re-sand with Gator Maxx and address the grade so runoff moves away from the slab instead of across it.
- Driveway settlement across the board. San Antonio’s expansive clay shrinks during drought and swells after rain. Pavers and concrete driveways both move. We diagnose whether the issue is base failure, drainage failure, or both before recommending a repair path.
Unilock Service in San Antonio: What Local Conditions Mean for Your Equipment
Here is the part most out-of-town contractors miss. San Antonio has no municipal zoning. None. That means homeowners across the city have added driveways, patios, and walkways without a clear setback map or utility easement document to guide the work. When we start digging, we routinely hit limestone shelf rock just inches below the grass line, and we call 811 multiple times on the same property because utility laterals are scattered. You do not face this as sharply in Austin or New Braunfels. In Alamo Heights and Terrell Hills, bedrock can sit a foot down, turning a simple edge-course reset into a jackhammer job. For Unilock owners, this means your paver driveway or patio is only as stable as the base we build around that limestone and caliche. That instability is also why we emphasize base preparation and drainage on every job. A paver is a manufactured product. The ground under it is a San Antonio condition. On a recent project in Terrell Hills, we reset a 400-square-foot Old Greenwich driveway where one side had settled almost two inches after the 2023 summer drought. Our tech jackhammered out a limestone ridge under the edge course, brought in 8 tons of compacted road base, and re-laid the original pavers with new Gator Maxx sand. The owner’s parking pad now drains away from the slab instead of toward the garage. That is the difference between patching a paver and fixing the San Antonio ground beneath it. We cover all of this as part of our San Antonio service area work.
Unilock Models & Products We Service in San Antonio
We install and repair the full range of Unilock hardscape products homeowners in San Antonio actually use, including our Bathroom Remodeling in San Antonio. That includes Estate Series pavers, Eco-Promenade permeable pavers, Rivercrest wall units, and Old Greenwich pavers. When a unit needs replacement, we order genuine Unilock product so the fade and texture match the surrounding field. When a section has lost its structural base entirely, we usually recommend re-compacting and resetting the original units rather than spot-patching, because a patch over a failed base will fail again. For materials like polymeric sand, joint stabilizer, and compacted road base, we use quality aftermarket products that are stocked locally for faster San Antonio turnaround. The goal is the same whether we are repairing eight pavers or installing an entire driveway: the finished surface should look intentional and stay put through San Antonio’s drought-and-flood cycle.

What drives the cost in San Antonio? Shallow bedrock adds excavation time. Expansive clay means deeper base prep. No zoning means we may spend extra time locating utilities before we dig.

FAQs – Unilock Construction in San Antonio
Yes, when the base is prepared correctly. Unilock pavers are engineered for heavy loads, but no paver survives a base that flexes over uneven limestone. We excavate down to the rock, add compacted road base, and level before laying. The paver is rarely the weak point. The prep is. Call (432) 233-0976 and we can assess your specific driveway.
Almost always the soil. San Antonio’s expansive clay shrinks during drought and swells after rain. That movement, not a manufacturing defect in Unilock pavers, is what causes sections to sink. We diagnose the cause, re-compact the base, and reset the original pavers where possible. Call (432) 233-0976 for a site walk and written assessment.
No. Spalling at the edge course is usually isolated to the units receiving constant water. We replace only the damaged pavers with genuine Unilock product, then adjust the irrigation heads so the overspray stops hitting the surface. The rest of the driveway stays intact. Call (432) 233-0976 and we can give you an exact replacement cost.
Yes, with the right base. Caliche is dense and drains slowly, so a standard permeable installation will underperform if the sub-base is not excavated deep enough. We dig out the caliche, install an open-graded base, and backfill so the permeable joints can actually infiltrate. Without that prep, you get ponding. With it, the system works. Call (432) 233-0976 for a free estimate on a permeable installation.
Because the footing soil expanded and shifted, not because the Rivercrest wall units failed. When clay swells after rain and then shrinks during drought, walls without proper drainage and a deep enough buried course will lean. We rebuild the footing, add drainage gravel behind the wall, and reset the units. Call (432) 233-0976 for a full assessment and written price.
