Why San Antonio Homeowners Choose Unilock Construction
We provide independent San Antonio Unilock service, handling everything from paver driveway installs to patio rebuilds and edge restraint repair. Our crew has rebuilt, re-leveled, and re-edged more Unilock paver surfaces across San Antonio than most local GCs, so we know the difference between a failing paver and a failing base. We’re not a Unilock dealer and we’re not authorized by Unilock. We’re a local remodeling contractor that works on their products every week. Call (432) 547-6806 for a free estimate.

What makes our Unilock work different is simple: we treat the base like the foundation it is. In San Antonio, expansive clay soils heave and shrink through every drought and downpour cycle. A paver surface that looks good for six months and fails in year three is usually a base problem, not a paver problem. We fix both. Luca Romano, owner of Sawyer Remodel San Antonio, learned the trade at Los Angeles Trade-Technical College and has spent decades on real job sites across the Southwest. He still walks every finished job himself because handing over a level, solid surface is the part of the work that matters.
Why Trust Sawyer Remodel San Antonio for Your Unilock Construction?

Unilock makes a dozen-plus paver lines, and they don’t all fail the same way. Brussels Block reacts differently to clay heave than Richcliff does. Town Hall has different joint tolerances than Camelot. If a crew doesn’t know that, they’ll give you a generic fix that might hold for a season and then fail again. Our technicians work with Unilock products directly: we identify the series, check the base condition, and fix the actual cause, not just the symptom.
We’re an independent New Braunfels Unilock service provider, which means we’re free to tell you when a repair is worth it and when replacement is the honest call. We use genuine Unilock units when color-matching matters and premium polymeric sands and drainage fabrics that meet or exceed OEM specs when base performance matters more. Every job gets a written price before work starts, a live arrival time, and photo updates before and after. That’s the Relay Standard, and it applies to every Unilock job we touch in San Antonio. Luca’s philosophy runs through all of it: the craft comes first. Everything else follows.

Common Unilock Construction Problems We Fix in San Antonio
Here are the Unilock-specific failures we see most often in San Antonio, and why they actually happen:
- Edge restraint failure on driveways. When the plastic or aluminum edging along a Brussels Block or Town Hall driveway loosens or shifts, the outer pavers start spreading. You’ll see gaps opening along the border and the whole surface losing interlock. This is a restraint problem, not a paver problem, and it’s one of the most common issues on San Antonio driveways where vehicles cross the edge daily.
- Settling and rutting from clay-rich soil. San Antonio’s expansive clay swells when wet and shrinks when dry. If the base wasn’t compacted properly or lacks geotextile separation, paver surfaces settle into waves and ruts. We see this constantly in Alamo Ranch, Helotes, and other northwest-side neighborhoods where the clay is especially active. The pavers themselves are usually fine; the base underneath needs rebuilding.
- Efflorescence and surface pitting. White crusty stains on Unilock pavers are efflorescence: mineral salts rising through the paver as moisture evaporates. It’s common after San Antonio’s periodic heavy rains and flash flooding. Power washing alone won’t stop it from returning. The joint sand needs to be cleaned and replaced with a quality polymeric sand, and drainage needs to be checked so water isn’t pooling under the surface.
- Cracked or spalled pool coping. Unilock coping units around pools take a beating from freeze-thaw cycles and de-icing salts. Edges spall and flake. In San Antonio’s climate, the bigger culprit is usually UV exposure plus poor drainage behind the coping, which lets water sit against the units and degrade them slowly.
- Joint sand washout. After heavy rain, you should not see channels forming between pavers. If you do, the joint sand is washing out and the pavers will start shifting. This is a maintenance reality in San Antonio’s flash-flood conditions, and it needs to be caught before the base erodes and individual units crack under uneven load.
Unilock Parts & Our Repair-vs-Replace Approach

Here’s how we think about parts and the repair-or-replace decision, so you know exactly what you’re paying for and why.
When color-matching matters for a repair or an extension, we source genuine Unilock units so the new pavers blend with the existing surface. Unilock’s color blends vary slightly by manufacturing run, so pulling from the same product line is the only way to get a close match. We also stock compatible polymeric sands, edge restraints, and drainage fabrics locally so we’re not waiting on shipments for common repairs.
We don’t automatically push replacement. If a few pavers are cracked or a small section has settled, repair is usually cheaper and gets the surface back to level. But we’re honest about thresholds: if base failure affects more than 30% of the surface, you’re throwing money at a losing battle. Rebuilding the base and reinstalling the pavers is the right call at that point. Call (432) 547-6806 and we’ll give you a straight answer, not a sales pitch.
Our Unilock Service Process – Step by Step
- 1
Diagnosis. We walk the surface with you, check for edge restraint movement, joint sand condition, and base settlement. We identify which Unilock series you have and note any color-matching or drainage issues specific to San Antonio’s clay and drainage patterns.
- 2
Written price. Before any work starts, you get a line-item price in writing. The number you approve is the number you pay. No surprises at the end.
- 3
Repair or install. For repairs, we excavate only what’s needed, compact properly, and reinstall with new edge restraints and polymeric sand. For installs, we build the base from the ground up with geotextile and proper compaction.
- 4
Test and finish. We run water over the surface to check drainage, verify edge restraints are secure, and walk every inch with you before we call it done.
- 5
Warranty. Every Unilock job carries our 365-Day Done Right Promise: if it’s not done right, we make it right, in writing.

FAQs – Unilock Construction Service in San Antonio

Edge restraint failure is the culprit in most cases. The plastic or metal edging that holds the perimeter pavers in place loosens or breaks, and the outer units start drifting outward, breaking interlock across the surface. Repair involves resetting or replacing the edge restraint and re-tensioning the pavers with fresh joint sand. Call (432) 547-6806 and we’ll inspect it before it spreads further.
Yes, we match existing Unilock Richcliff pavers for patio extensions. We source genuine Unilock units from the same product line and work to match the color blend as closely as the manufacturing run allows. It won’t be invisible, but it’ll blend well enough that only you’ll notice. Call (432) 547-6806 for a free estimate on the extension.
Yes, efflorescence and spalled edges on Unilock pool coping are usually repairable. The white crust is mineral salt, and we treat it by cleaning the surface, replacing joint sand, and correcting drainage behind the coping. Spalled edges on individual units can sometimes be addressed by rotating or replacing those units. If the damage is isolated, repair is cheaper than full coping replacement. Call (432) 547-6806 to have it looked at.
A properly installed Unilock Construction in Alamo Heights, TX driveway should last 25 to 30 years with periodic joint sand top-ups and edge restraint checks. The pavers themselves will outlast the base if the base was built right. The wild card here is the expansive clay soil. Get the base wrong and you’ll see waves and ruts within five to seven years. Get it right, with geotextile and proper compaction, and it holds through drought and flood cycles.
We use premium polymeric sands that meet or exceed Unilock’s specs for joint performance. When a project calls for a specific Unilock jointing compound for color or texture reasons, we’ll use that. But most of the time, the best-performing polymeric sand on the market does a better job in San Antonio’s climate than the basic options, so that’s what we install. Call (432) 547-6806 if you want to talk through options for your specific surface.
