Unilock Driveway & Pavers: The Austin Owner’s Guide
If you’re looking for Unilock driveway pavers or replacement pieces in Austin, the installed price for a paver driveway typically runs $7,000 to $18,000, and repair work on existing Unilock surfaces usually falls between $400 and $2,500 depending on how many units need pulling and re-setting. We stock Unilock-compatible pavers and can match most current and recently discontinued Unilock lines, often same week. Most Austin homeowners find out they have a problem the hard way: a paver shifts under a car tire, a section sinks after a heavy rain, or efflorescence (that white chalky film) shows up across the surface and won’t wash off.
Which Unilock Models This Applies To
Unilock breaks their product lines into a few families, and the part you need depends on which one is in your driveway. The most common in Austin are the EnduraColor series (including Beacon Hill, Courtstone, and Richcliff), the U-Cara multi-piece wall system, and the older Brussels Block and Hollandstone lines that were installed heavily in Texas suburbs through the 2000s and 2010s. Each series uses different joint widths, thicknesses, and edge profiles, so a Richcliff paver will not sit right next to a Brussels Block unit even if the color looks close.
Here’s the compatibility gotcha most people don’t know until it’s too late: Unilock pavers have the series name and a part code molded into the underside of the paver. Flip one over before you call us. If the code is worn off, measure the thickness. Most Austin driveway pavers are 60mm or 80mm. Residential driveways should be 80mm; some builders cut corners with 60mm and those fail faster under Texas heat and clay soil movement. We carry both thicknesses in common Austin colorways (Sierra, Sandalwood, and Burnt Clay).
On OEM versus aftermarket: Unilock pavers are concrete units, not precision mechanical parts. A quality aftermarket match from a Texas supplier is fine for most repairs if the color, size, and texture align. The failure point isn’t usually the paver itself, it’s the bedding and joint sand underneath, which is where we spend most of our labor time. For current EnduraColor lines, we recommend OEM to keep the color warranty intact.

Signs Your Unilock Driveway & Pavers Is Failing
- Sinking or low spots. Austin’s black clay soil expands and contracts hard with moisture swings. If the gravel base wasn’t compacted right, pavers sink and hold water after rain. You’ll see puddles that stay for hours.
- Shifting pavers with a gap at the edge. The edge restraint has failed or was never installed. Without it, the whole field walks outward over time. You’ll notice a widening gap against the curb or garage slab.
- Weeds and sand loss between joints. Polymeric sand has broken down or washed out. Joints widen, pavers rub against each other, and edges start chipping. This is the earliest warning sign and the cheapest fix.
- White chalky film across the surface. Efflorescence from moisture moving through the paver. Common on shaded Austin driveways and north-facing slopes where the surface never dries out completely. It’s cosmetic but it means water isn’t draining correctly.
- Cracked or spalled pavers in car-tire paths. A 60mm paver on a soft base under daily vehicle load will crack. We see this constantly on older homes in Bouldin Creek and Travis Heights where drives are short and tight, so the same tire path gets hammered daily.
Replacement Cost & What’s Included
In Austin, spot repair on a Unilock driveway runs $400 to $2,500 when we’re pulling up to roughly 100 square feet, fixing the base, and re-setting the pavers. A full paver driveway installation lands between $7,000 and $18,000 depending on the square footage, paver thickness, base depth (we go deeper than code minimums), and access to your yard. The range is wide because a 400-square-foot driveway with easy access is a different job than an 800-footer behind a narrow fence gate in Crestview where every wheelbarrow load is a hike.
What’s included in our number: demolition and base excavation, gravel sub-base and sand bedding, paver material (OEM Unilock or matched equivalent), edge restraints, polymeric joint sand, and compaction. We write the price before we start and the number on the invoice is the number you approved. The work is covered under our 365-Day Done Right Promise, and if the base settles within that year, we come back and re-set it. No charge.

AfterDIY or Call Us?
Here’s the honest split. You can safely diagnose a failing driveway yourself: look for standing water, run your hand across joints to check for sand loss, and check if edge pavers have shifted. That part costs you nothing and helps you talk smart when you call us. What you shouldn’t DIY is pulling up a section of driveway and re-setting it. Pavers are heavy (80mm units run 20 to 25 pounds each), an improperly compacted base will sink again within a season, and Austin’s clay soil means you’re fighting the ground the whole time if you don’t have plate compactors and the right gravel mix.
Plus, there’s a practical limit: nobody wants a half-finished driveway for three weekends while they learn on the job. We’ve fixed enough DIY attempts in the Zilker and Barton Hills neighborhoods to say this with confidence. Measure twice, cut once, then we actually build the thing. Call (409) 834-4854 if you’d rather have it done once, correctly, with a written price before the first paver comes up.
FAQs
Unilock driveway pavers in Austin typically last 25 to 40 years when installed on a properly compacted base with adequate drainage. The pavers themselves are concrete units rated for decades of use, but the base material underneath is usually what fails first in Central Texas due to expansive clay soil and heavy rain cycles. A 60mm paver on a thin base may show problems within 5 to 10 years. If you’re unsure what’s under your driveway, we’ll core a small test hole during the estimate and tell you exactly what you’re working with. Call (409) 834-4854 to schedule a free inspection.
Yes, in most cases individual damaged pavers or small settled sections can be pulled, the base re-compacted, and the pavers re-set for $400 to $2,500 depending on the size of the repair area. You only need full replacement when the base has failed across a large section, paver thickness is wrong for vehicle loads, or you’re changing the driveway layout. We always quote repair before jumping to replacement. For an exact number on your driveway, call (409) 834-4854 and we’ll put a written price in front of you before any work starts.
Most spot repairs on Unilock driveways in Austin take one working day, while a full paver driveway installation runs three to five days depending on size, access, and weather.
