Unilock Driveway & Pavers: The San Antonio Owner’s Guide
Unilock paver driveway installation in San Antonio runs $7,000 to $18,000 for a standard two-car driveway, and we stock a full range of Unilock-compatible pavers, edge restraints, joint sand, and base materials on our trucks. If your Unilock driveway or patio has shifted, sunk, or cracked at the edges, the fix is usually the base layer, not the pavers themselves, and we can typically assess and quote the repair the same day we look at it. Homeowners most often discover a problem after a heavy rain when they see a low spot holding water, or when a paver rocks underfoot near the edge of the driveway.
Which Unilock Models This Applies To
Unilock makes pavers and wall systems, not a single model, so the compatibility question comes down to the product line: Brussels Block, Courtstone, Thornbury, Richcliff, Beacon Hill Flagstone, Mattoni, and Town Hall are the lines we see most on San Antonio driveways and patios. The gotcha is that each line has its own thickness and dimensional tolerance. Brussels Block runs 60mm thick, which handles driveway loads when installed over a proper base, while some of the thinner patio lines like Mattoni sit at 40mm and will crack under vehicle weight. If you don’t know which line you have, flip over a loose paver and look at the back. Most Unilock pavers have the series name stamped or embossed on the underside, and that’s the fastest way to confirm what you’re working with before anyone starts matching product.
On the OEM versus aftermarket question: Unilock pavers are manufactured with a specific aggregate mix and a surface texture that’s hard to match perfectly from a different plant. We recommend OEM Unilock product whenever it’s available. Color lots shift between manufacturing runs, so if you’re patching an existing driveway, we’ll order from the current lot and blend the new pavers in from a less visible area of the existing installation, moving the old ones to the patch zone. That’s the detail that keeps a repair from looking like a patch job. Sawyer Remodel San Antonio is an independent service provider, not affiliated with Unilock, which means we match product honestly and tell you when a color match is going to be close rather than exact.

Signs Your Unilock Driveway & Pavers Is Failing
- Water pooling in low spots after rain. This means the base underneath has settled or washed out in that area. In San Antonio’s clay-heavy soil, the freeze-thaw cycle is less of a factor than the drought-soak cycle, where soil contracts during dry months then swells and shifts when the rain finally hits.
- Pavers rocking or clicking when you walk or drive over them. A rocking paver means the bedding layer has broken down or the paver has cracked at a corner. Rocking pavers chip fast, and a chipped corner on a 60mm Brussels Block is a trip hazard, not just an eyesore.
- Edge pavers separating from the main field. This is an edge restraint failure. The plastic or aluminum edging wasn’t spiked deeply enough or has pulled loose, and once the edge lets go, the whole field starts creeping outward under vehicle load.
- Weed growth or ant mounds between joints. Polymeric sand has failed or was never installed. Once weeds root in the joints, they hold moisture against the paver sides, and that moisture accelerates edge chipping and movement.
- Visible cracks running through multiple pavers in a line. A straight-line crack usually points to a base or sub-base problem, not individual paver failure. The pavers are just broadcasting what the ground underneath is doing.

AfterReplacement Cost & What’s Included
For a full Unilock driveway replacement in San Antonio, budget $7,000 to $18,000 depending on square footage, access, and whether the existing base can be salvaged or needs full excavation and rebuild. For a repair rather than a full replacement, a smaller job like resetting a sunken section or replacing failed edge restraint typically falls between $500 and $3,500. The range is driven by three things: how much base has to be removed and recompacted, whether we can reuse your existing pavers or need new product, and whether site access allows machinery or requires hand work.
Every quote includes the base work, bedding sand, pavers, edge restraint, joint sand, and haul-off of the old material. You’ll get a written price before any work starts, and the number on that quote is the number you pay. Every Unilock paver job we do carries our 365-Day Done Right Promise: if something isn’t done right, we make it right. In writing, on every job.
DIY or Call Us?
Here’s what you can safely check on your own: sweep your Unilock driveway clean and look for low spots, cracked pavers, loose edges, and joints where sand has washed out. Mark the problem areas with chalk or tape and take photos. That’s genuinely useful information for us before we arrive.
What you shouldn’t do is start pulling pavers to “see what’s underneath.” The base layer is load-bearing and engineered. Once you break the compacted base or disturb the bedding layer, you’re committing to a rebuild, and doing it by hand without a plate compactor means the repair will sink again within a year in San Antonio’s clay soil. The same applies to edge restraints. If we skip proper recompaction, the repair fails and we’re back out under warranty anyway, so our crew does it right the first time. If you’ve got a paver problem, take the photos and call us at (432) 547-6806. The estimate is free.
FAQs
Unilock pavers themselves typically last 25 to 40 years, but the installation’s lifespan is set by the base. In San Antonio’s clay soil, a properly compacted base should hold for 20-plus years before you see meaningful movement. We see driveways that need base work at the 10 to 15 year mark, usually because the original installer skimped on base depth or compaction. Call (432) 547-6806 and we’ll tell you if your problem is a simple paver repair or a base rebuild before we book anything.
Yes, partial repairs are common and often the right call. A sunken section, failed edge, or cracked cluster can usually be isolated, rebuilt, and re-laid without touching the rest of the driveway. The main reason a repair turns into a replacement is base failure across a wide area or a color-lot mismatch so severe the patch would look wrong. Get a quote at (432) 547-6806 and we’ll give you both options in writing.
Most paver repairs take one day on site. A full driveway teardown and replacement usually runs two to four days depending on size, access, and how much old base material has to be hauled off. You’ll get a written schedule with the quote, and our arrival time is tracked live under The Relay Visibility Guarantee, so you’re not burning a day waiting on a crew that hasn’t shown.
We keep common Unilock line items and all the structural pieces on the trucks: edge restraints, spikes, bedding sand, and polymeric joint sand. Product-specific pavers are ordered per job from the local Unilock distributor so you get the current color lot rather than a warehouse compromise. Call us at (432) 547-6806 with your paver’s series name from the back of a paver and we’ll tell you exactly what’s available for your repair.
