Call (432) 547-6806 for a free estimate on any Unilock project.
Why Alamo Heights Residents Choose Us for Unilock Service
Plenty of crews can lay pavers. Far fewer can diagnose why an existing Unilock patio is sinking along the foundation line of a 1930s Tudor, or why joint sand keeps washing out after every heavy rain. That’s the difference. Luca Romano, our owner, grew up in East Los Angeles and learned the trade at Los Angeles Trade-Technical College before spending decades running hardscape and remodel jobs across the Southwest. He and our crews have worked Alamo Heights long enough to know that every block has its own drainage pattern and that roots from a 60-year-old live oak don’t respect property lines. We bring that local familiarity to every Unilock job we quote. We’re an independent service provider, which means we’re not tied to a single manufacturer’s sales targets. Our job is to tell you straight whether your existing Unilock pavers can be salvaged or whether full reinstallation makes more sense.

Common Unilock Construction Problems We Solve in Alamo Heights
Unilock makes a solid product. But nothing lasts forever in this climate. Here’s what we see most often around Alamo Heights:
- Edge restraint failure on paver driveways. When edge restraints pull away or were never installed properly, pavers migrate outward and sink along concrete curbs and foundations. We see this on older Alamo Heights homes where driveways were built right up against the house, leaving no room for error. We re-set the edge, install proper restraints, and re-lay the affected rows.
- Joint sand washout after heavy rain. Alamo Heights gets hit with intense downpours and flash flooding in spring and fall. Polymeric sand that’s old or improperly activated washes out of paver joints, leaving pavers rocking and uneven. We remove the old sand, clean the joints, and re-sand with a properly activated product matched to the Unilock line.
- Efflorescence and surface spalling. The clay-rich soils around Alamo Heights hold moisture against the underside of pavers. That moisture wicks up through older Unilock pavers, leaving white mineral deposits on the surface. Over years, it can cause spalling, where the top layer flakes off. We can clean efflorescence and replace spalled pavers when the base is still sound.
- Heaving and cracking over expanding clay. This is the big one. The clay soil under Alamo Heights expands and contracts with every wet-dry cycle. Pavers laid without proper base prep lift and crack as the ground moves beneath them. We see sections pushed up by roots as much as by soil movement. When the sub-base is shot, we re-excavate and rebuild it properly.
- Root displacement along driveways. Mature live oaks and other protected trees send roots under paver surfaces, lifting whole sections of driveway or patio. This isn’t something a quick re-level fixes. We hand-dig around the root zone, install barriers, and re-lay the pavers on a stable base.
Unilock Service in Alamo Heights: What Local Conditions Mean for Your Equipment
Here’s a fact about Alamo Heights that shapes every Unilock project here: the city’s tree preservation ordinance is strict, and protected live oaks dictate where pavers can go and how the base gets built. You can’t just scrape the ground flat with a machine near a protected tree. Our crews often hand-dig root zones ourselves, and we install root barriers before laying Unilock pavers. In practice, that adds about 15 to 20 percent to labor on an Unilock driveway compared to a city without the same rules. It’s not optional work, though. Skip the root barrier, and a mature live oak will push new pavers out of alignment within a few years. We’d rather build it right the first time and have you call us for a new project, not a warranty claim.
Our crew rebuilt a Unilock Courtstone driveway on Arvin Road where a mature live oak had lifted and displaced a 6-foot swath of pavers near the garage. We hand-excavated around the root flare, installed geotextile fabric and a root barrier, then re-laid the Courtstone with new edge restraints and polymeric sand. That driveway has now sat through two spring hailstorms and not a single paver has shifted. That’s what local knowledge buys you.
Unilock Models & Products We Service in Alamo Heights
We work across the Unilock lineup that shows up most often on Alamo Heights properties. That includes Unilock Brussels Block, a classic tumbled paver that fits right in with older Craftsman homes. Unilock Courtstone shows up on a lot of driveways and pool decks around here, and it’s what we re-laid on Arvin Road. Unilock Richcliff and Unilock Thornbury are newer lines we see on modern additions and full replacement jobs. Our parts policy is straightforward: when we’re matching existing patterns or repairing a small section for our Bathroom Remodeling in Alamo Heights, we use genuine Unilock pavers and matching joint sand. If the original line has been discontinued and a full replacement makes sense, we’ll recommend a current Unilock line that fits the home’s era and style. We keep common replacement pavers and sand stocked locally so Alamo Heights jobs don’t stall waiting on a pallet from out of state.

FAQs – Unilock Construction in Alamo Heights
They can if the base is built correctly. Clay soil expands and contracts with moisture, and that movement transfers straight through pavers if the base is too thin or poorly compacted. The fix is proper excavation, a well-compacted aggregate base, and the right joint sand. Pavers themselves rarely crack from soil movement; they crack when the base fails underneath them. Call (432) 547-6806 and we’ll tell you whether your existing base was built for this soil or needs to be redone.
Unilock Brussels Block is the one we recommend most for pre-war Alamo Heights homes. Its tumbled edges and muted color range read as aged and settled, which suits Spanish Eclectic front entries and side patios better than a crisp, modern paver. Courtstone also works well, especially for driveways. Come to your estimate with photos of the home and we’ll set samples against the exterior so you can see the match in daylight.
Without root protection, yes, they probably will. Alamo Heights’ protected live oaks send roots out far past the canopy, and those roots will lift pavers over time. We hand-dig near root zones and install root barriers before the base goes in. That’s standard practice for our crew in the 78209 ZIP code, not an add-on. It adds some labor cost, but it’s the difference between a driveway that lasts 10 years and one that needs re-leveling in three.
We pull the settled pavers, inspect the base and any edge restraints, then rebuild the section from the bottom up. On older Alamo Heights homes, the original edge restraints are often missing or degraded, which lets pavers sink right against the foundation line. We re-establish the edge, compact the base, and re-lay the pavers with matching sand. If the sub-base is intact, this is a targeted repair, not a full replacement. Call (432) 547-6806 and we’ll give you a written price for the section that needs work.
Joint sand washout. Alamo Heights gets brief but intense downpours, and old or improperly sealed polymeric sand washes right out of paver joints. Within days, pavers start rocking and shifting under foot. We remove the old sand, clean the joints, and re-sand with an activated product that holds through the next storm. If your patio feels loose after rain, call (432) 547-6806. A re-sand now is a lot cheaper than a full re-lay later.
