Unilock Driveway & Pavers: The Austin Owner’s Guide
Unilock driveway and paver installation in Austin typically runs $7,000 to $18,000 for a standard two-car driveway, depending on square footage, the paver line you choose, and how much base prep the soil requires. We stock Unilock pavers and can usually have your project quoted within 48 hours. Most Austin homeowners discover they need us after a hard freeze or heavy rain season: pavers sink, edges separate, weeds push through joints, or a section of the driveway looks like it’s slowly sliding toward the street.
You’re not imagining it. Austin’s clay-heavy soil expands and contracts with moisture more aggressively than almost anywhere in Texas, and Unilock pavers sit directly on top of that movement. When the base layer isn’t done right – or when it was done years ago and has since eroded – the pavers shift. The fix usually isn’t replacing individual pavers. It’s rebuilding what’s underneath them.
If you’ve got a Unilock driveway in Mueller, Tarrytown, Circle C, or anywhere else in Austin, this guide covers what fails, what it costs to fix, and whether you should touch it yourself.
Which Unilock Models This Applies To
We work with the full Unilock paver catalog, but most Austin driveways we see use Hollandstone, Brussels Block, Courtstone, Richcliff, or Umbriano. Each has a different profile, joint width, and thickness spec, and that matters when it comes to matching replacement pavers. A Hollandstone paver is 60mm thick with a chamfered edge. Richcliff runs 60mm to 80mm depending on application and has a more irregular, flagstone-like face. If you mix a 60mm paver into an 80mm run, you’ll feel the height difference every time you roll a trash bin over it.
Here’s the compatibility gotcha most people don’t know: Unilock changes paver color lots over time, and a paver you bought in 2018 may not match the same color name in 2026. Sun fading does the rest. Austin’s UV exposure is relentless. That’s why we always match from physical samples, not product codes alone. If you have leftover pavers from the original install, keep them – they’re the most accurate color reference we’ll ever get.
On OEM versus aftermarket: Unilock doesn’t really have an “aftermarket” in the way appliance parts do. What you’re buying from us is genuine Unilock product, sourced through our supplier partnerships that include Belgard and Techo-Bloc as alternates when a customer wants a different look. We recommend staying with genuine Unilock for driveway repairs because the dimensional tolerances match what’s already in the ground. Off-brand “lookalike” pavers from big-box stores are usually 50mm thick, which means your repaired section will sit lower than everything around it.

Signs Your Unilock Driveway & Pavers Is Failing
- Pavers sinking in one area. This almost always means the base underneath that section has washed out or was never compacted properly. Austin’s heavy spring rains push fine soil through the base rock, creating voids that the pavers slowly collapse into.
- Edges creeping outward. Driveways without proper edge restraint – usually a concrete or aluminum edge buried along the border – will spread under vehicle weight. You’ll see a widening gap between the driveway and your lawn or garage apron.
- Weeds or grass growing through joints. Normal joint sand washes out over time, and once it’s gone, weed seeds find a home. More than a cosmetic issue, it signals that the interlock between pavers is weakening.
- Standing water after rain. A properly pitched Unilock driveway drains in under an hour. Puddles that stay for a day mean the pavers have shifted enough to change the slope, and water is now working against you instead of away from you.
- Loose or rocking pavers underfoot. When you step on a paver and it moves, the joints have failed and the individual unit is no longer locked into the surrounding field. Left alone, that one loose paver becomes ten.

AfterReplacement Cost & What’s Included
Paver driveway installation in Austin runs $7,000 to $18,000 for a full project. If you’re repairing a section rather than replacing everything, we price by the square foot based on what we find when we open it up. A typical 200-square-foot repair of failed base and pavers usually lands between $2,500 and $5,000.
Here’s what drives cost:
- Base rebuild depth. Austin code for vehicular paver applications generally calls for 6 to 8 inches of compacted base rock, plus 1 inch of bedding sand. If the original installer cut corners, we’re digging deeper and hauling more material.
- Paver line and thickness. Richcliff and Umbriano cost more per square foot than Hollandstone. Thicker pavers cost more to buy and more to ship.
- Access and demolition. A driveway with easy street access and a clear path for equipment costs less than one behind a gate or up a slope.
- Drainage corrections. If water has been pooling because the original pitch was wrong, fixing the slope adds labor and sometimes a channel drain.
Every quote is written and line-itemed before work starts. You’ll see the material cost, the labor, the haul-off, and the warranty terms. Our workmanship warranty covers paver installation for 365 days from the completion date. If your pavers shift, sink, or separate in that window, we come back and fix it at no cost. That’s the 365-Day Done Right Promise, and it applies here just like it does on our kitchen and bath remodels.
DIY or Call Us?
You can safely do a few things yourself. Pulling weeds and refilling joint gaps with polymeric sand is a weekend job most Austin homeowners can handle. It won’t fix a structural problem, but it will slow down the damage and buy you time.
What you should not do is lift pavers and try to rebuild the base yourself. A Unilock driveway is a load-bearing surface. Pavers on a bad base channel vehicle weight unevenly, which means one section holds the weight of your F-150 while another section flexes. The risk isn’t just a bad-looking driveway – it’s cracking pavers, trip hazards, and a repair bill that doubles because the failed patch now has to be torn out before the real fix can start. Digging out and compacting base material properly requires a plate compactor, correct aggregate, and moisture management. Most homeowners don’t have that equipment in the garage. Isaac Pruett’s crew does.

FAQs
Unilock pavers themselves carry a transferable lifetime warranty against manufacturing defects, and the units routinely hold up for 30 to 40 years in Austin’s climate. The base underneath them, however, typically needs attention every 15 to 20 years depending on soil movement and drainage. A paver driveway that’s failing at year 10 almost always has a base problem, not a paver problem. Call (903) 623-1966 and we’ll tell you which one you’re dealing with.
Yes, individual pavers can be swapped out. The catch is color matching – Austin sun fades pavers unevenly, so a brand-new paver often stands out against the surrounding field for a year or two until it catches up. We pull from your leftover stock if you have it, or match from the closest current Unilock lot. If the damage comes from a structural issue below, replacing the paver alone won’t fix it, and you’ll be looking at the same problem again after the next freeze-thaw cycle.
A standard two-car driveway replacement in Austin takes 3 to 5 working days from demolition to final compaction. Smaller repair sections can often be done in a single day. Weather plays a role – we can’t compact wet base material properly, so rain days push the schedule. We’ll tell you the timeline in writing before we start.
We stock the most common Austin driveway lines – Hollandstone, Brussels Block, and Courtstone – in our most requested color blends. Specialty lines like Richcliff and Umbriano are ordered per project, which typically adds 5 to 7 business days to the schedule. We’ll tell you up front what’s in stock and what isn’t, and the lead time is written into your quote.
