Unilock Driveway & Pavers: The Santa Clarita Owner’s Guide
Unilock paver driveway installation in Santa Clarita runs $7,000 to $18,000 installed, with most driveways landing between $9,500 and $14,000 depending on square footage, paver line, and base prep. We stock and install Unilock-compatible pavers, edge restraints, bedding sand, and polymeric joint sand, and we can usually get your driveway repaired or replaced within one to two weeks of the estimate. Most Santa Clarita homeowners find us after a winter of rain, when pavers start shifting, sinking, or separating at the edges.
You’ll know something’s wrong when you feel a paver rock under your tires, see water pooling in a low spot, or watch weeds push up through the joints a few months after they were “sealed.” This page tells you what’s actually failing, what it costs to fix in Santa Clarita, and whether you should grab a rubber mallet or call us.
Which Unilock Models This Applies To
This covers the Unilock paver lines installed most often in Santa Clarita driveways, patios, and walkways: Brussels Block, Courtstone, Hollandstone, Mattoni, Richcliff, Thornbury, and the permeable Town Hall and Eco-Optiloc systems. Each line uses a specific joint width and bedding layer, and matching the wrong paver to an existing driveway is the most common install mistake we see.
The fast way to identify what you have: look at the leftover paver from the original job, or pull one from the edge and check the back. Unilock stamps product codes on the underside of most pavers, plus a date code that tells you which manufacturing run it came from. Color lots vary between runs, so even the exact same paver bought two years apart will show a visible shade difference. That’s why we order full pallets for repairs, never single boxes.
For driveway applications specifically, you want a minimum 60mm paver thickness. The 80mm commercial-grade pavers hold up better under Santa Clarita’s summer heat cycles and the occasional delivery truck or RV. As an independent contractor, we’re not affiliated with Unilock, but we install their product lines because they’ve held up reliably across hundreds of driveways we’ve done in the SCV.
Styles & brands we work with
Signs Your Unilock Driveway & Pavers Is Failing
- Sinking or rutting in the wheel paths. The base layer wasn’t compacted deep enough, or water has eroded the aggregate underneath. In Santa Clarita’s clay-heavy soil, poor drainage accelerates this faster than almost anything else.
- Pavers shifting or separating at the edges. The edge restraint, usually plastic or aluminum, has failed or was never installed. Once the border lets go, the rest of the field follows within months.
- Weeds or ants pushing through the joints. Polymeric sand has broken down or washed out. Left alone, the joints widen, pavers start moving, and the cycle gets worse every rain.
- White haze or surface flaking. This is efflorescence or spalling, common in cheaper concrete pavers but sometimes showing up in older Unilock lots. Sun exposure on Santa Clarita’s southwest-facing driveways accelerates spalling on any concrete product.
- Standing water that takes hours to drain. The slope was never set correctly, or the base has settled unevenly. Puddles that sit against the garage slab will eventually find their way under it.

AfterReplacement Cost & What’s Included
A full Unilock paver driveway in Santa Clarita runs $7,000 to $18,000 installed. The range depends on three things: square footage, the paver line you choose, and how much of the existing base we have to remove and rebuild. Here’s the line-item breakdown:
- Demo and haul-off of existing driveway: $1,200 – $3,500
- Excavation and base prep (6 – 8 inches of compacted aggregate): $2,000 – $5,000
- Unilock pavers, bedding sand, edge restraints, polymeric sand: $3,000 – $8,500
- Labor, screeding, compaction, finishing: $800 – $2,500
Every quote is a written, line-item price before we break ground. No change orders, no “we hit rock” surcharges. The 365-Day Done Right Promise covers the install: if a paver shifts, a joint fails, or the edge lets go within a year, we come back and fix it. That’s in writing on every job.
DIY or Call Us?
You can safely reset a loose paver, pull a weed, or sweep new polymeric sand into a few gaps. Those are maintenance jobs, not structural repairs. What you shouldn’t do is try to relevel an entire section, regrade the base, or replace edge restraints without pulling up the border. Pavers look simple, but once you lift a section you’ve disturbed the interlock, and getting it back flat without the right plate compactor and screed rails rarely works. Luca Romano has seen enough DIY releveling jobs that ended up worse than the original problem, with the homeowner paying twice to have it fixed.
If the issue is more than a few pavers, call us at (661) 592-1977. We’ll come out, tell you what’s actually failing, and give you a written price. No pressure, no guesswork.
FAQs
A properly installed Unilock paver driveway lasts 25 to 40 years in Santa Clarita’s climate, with the base layer doing most of the heavy lifting. Pavers themselves rarely fail; what fails is the base underneath or the edge restraint around it. If your driveway is sinking after five years, the problem isn’t the paver, it’s what’s under it. Call (661) 592-1977 and we’ll tell you honestly whether you need a repair or a full redo.
Yes, in most cases we can pull up a failed section, fix the base, and reinstall the original pavers if they’re still intact. The catch is color matching: older pavers have sun-faded, and new pavers from a different lot won’t blend perfectly. We’ll show you the match before we order anything. For a free estimate on a partial or full repair, call (661) 592-1977.
A typical Santa Clarita single-wide driveway takes three to five working days from demo to final compaction. Larger jobs or permeable paver systems with deeper aggregate bases can run seven to ten days. We’ll give you a written schedule before work starts, along with The Relay Visibility Guarantee: live arrival times, before-and-after photo updates, and a digital invoice you pay from a link.
We order directly from Unilock’s regional distribution, which means we get full pallets with matching lot codes, not mixed boxes from a big-box shelf. We also stock edge restraints, bedding sand, and polymeric sand on our trucks for repairs. The same applies to the other brands we carry parts for, including KraftMaid, Cambria, and Silestone. Call (661) 592-1977 and we’ll confirm availability and lead time before you commit to anything.
