Unilock Driveway & Pavers: The Orange County Owner’s Guide
Unilock driveway and paver installation in Orange County typically runs $7,000 to $18,000 for a full driveway, depending on square footage, base prep, and paver line. We stock Unilock-compatible pavers from the Brussels, Richcliff, and Thornbury lines, and can match most existing Unilock colors and sizes on the truck. Most Orange County homeowners discover they need replacement pavers after a few winters of rain and shifting clay soil: edges start to sink, joints open up, or individual pavers crack along the driveway’s load path.
If your Unilock driveway is showing settled spots, cracked units, or wide joints that let weeds through, you’re not alone. Orange County’s expansive soil, the kind that swells in winter rain and shrinks in August heat, works against even well-installed paver driveways. The fix is usually straightforward: pull the affected area, re-grade the base, and reset the pavers on compacted aggregate.
Which Unilock Models This Applies To
Unilock makes three paver families that dominate Orange County driveways: the Brussels Block (tumbled, old-world look), the Richcliff (linear, contemporary, comes in 3-piece modular sets), and the Thornbury (smooth-top, tight joints, often used for more formal driveways). Each family has its own joint width and unit dimensions. A Brussels paver is not interchangeable with a Richcliff paver, even if the color name matches.
Here’s the compatibility gotcha most homeowners hit: Unilock color names repeat across lines, but the pigment batches differ enough that a “Sierra” Brussels paver won’t match a “Sierra” Thornbury paver side by side. You need the exact product code from the underside of an existing paver, or a clear photo of the paver face and joint, to match it correctly. We pull the Unilock spec sheet before we order anything, so the replacement paver matches the driveway you already have, not a close approximation.
Unilock pavers are OEM-spec products. There’s a healthy aftermarket for “Unilock-compatible” pavers at big-box stores, but those units are often thinner, with looser dimensional tolerances. That translates to uneven joints and a patch that reads as a patch. For a driveway that carries vehicle weight every day, we recommend genuine Unilock units. The spec sheet is traceable, the color is consistent, and the compressive strength rating is documented.

Signs Your Unilock Driveway & Pavers Is Failing
- Settled or sunken sections along the wheel path. The base underneath has failed, usually because it was never compacted deep enough, or because water has washed fines out of the aggregate. Reset the pavers and the base, or the depression returns within a year.
- Wide, open joints with weeds or ant activity. Joint sand is gone, and that means the pavers are no longer locking against each other. Every rain event washes a little more base out, and the problem compounds.
- Cracked or spalled paver faces. A crack in the paver itself, not the joint, usually means point load stress: a heavy vehicle parked in one spot, or a paver bedded on a void. That paver is done; replacement is the fix.
- Edges dropping off along the driveway border. The edge restraint has failed or was never installed properly. Without edge restraint, the whole perimeter starts to migrate outward.
- Standing water pooling in low spots after rain. Paver driveways should drain. If water ponds, the sub-base is uneven or clogged. Orange County’s clay soil makes this worse, because water can’t percolate down once the aggregate is saturated.

AfterReplacement Cost & What’s Included
For a full Unilock driveway replacement in Orange County, budget $7,000 to $18,000 installed. The range comes down to three things: total square footage, how much of the existing base can be salvaged, and which Unilock line you’re matching. A partial repair, like resetting a settled wheel path or replacing a dozen cracked pavers, runs lower, but we quote that after we see the driveway.
Every Bradford Remodeling Co Orange County quote includes the paver units, new bedding sand, joint sand, base aggregate where needed, edge restraint repair, and full site cleanup. You get a written price before we start, and the number doesn’t move unless you change the scope. The 365-Day Done Right Promise covers the paver work too: if the pavers settle, crack, or the joints fail within a year of completion, we come back and correct it at no charge.
DIY or Call Us?
You can safely inspect your Unilock driveway yourself: look for sunken areas, open joints, cracked pavers, and standing water after rain. That tells you what’s failing. What you should not DIY is the reset itself. Pulling pavers without proper edge support will loosen the adjacent units, and a badly compacted base will resettle within a season. Paver work is not dangerous in the way a garage-door spring is, but the failure mode is expensive: a botched reset turns a $700 repair into a $14,000 driveway replacement.
If you’re in Orange County and your Unilock driveway is settling or cracking, call us at (562) 262-2907. We’ll look at the paver, tell you what it needs, and give you a straight number before any work starts.
FAQs
A properly installed Unilock driveway in Orange County lasts 25 to 30 years with basic maintenance, but the base underneath typically fails before the pavers do. Our clay soil expands and contracts with moisture, and that movement is what kills most paver driveways here by year 12 or 15, not the paver units themselves. If your base was compacted well and the edge restraint is solid, the pavers themselves will outlast the driveway. Call (562) 262-2907 and we’ll tell you honestly whether your base is worth saving or a full reset makes more sense.
Yes, in most cases a settled Unilock driveway section can be repaired without replacing the whole driveway, as long as the base failure is localized. We pull the affected pavers, re-compact the base, add fresh aggregate where it’s washed out, and reset the pavers to grade. If the settlement runs the full length of the wheel path, the repair starts to approach replacement cost, and we’ll show you that math before you decide. Estimates are free, and the written price covers the whole repair.
A typical settled-section repair on a Unilock driveway takes one day on site, sometimes two if we’re replacing a large area or the base needs a full re-grade. We don’t rush the compaction, because that’s the part that determines whether the repair holds. You’ll have the driveway back the same day for most partial resets. Call (562) 262-2907 and we’ll give you a timeline with the quote.
We stock common Unilock Brussels Block and Richcliff pavers on the truck in the colors we see most in Orange County, so we can usually start a repair the same week. Less common colors and the Thornbury line we order direct from the Unilock distributor, which adds a few days. Send us a photo of your pavers and we’ll tell you what we have on hand.
