Unilock Construction in Colton, CA | Polaris Contractors
We provide independent Unilock paver installation, repair, and rebuilding across Colton, ZIP 92324, and also offer Unilock in Grand Terrace. The thing that separates our Unilock work here from anywhere else in the Inland Valley: we design for expansive clay and 100°F heat cycling before we lay a single paver. Polaris Contractors is not authorized or financially affiliated with Unilock, but we know these systems on a level only comes from years of pulling up failed installations and fixing what the original base should have been.

Why Colton Residents Choose Us for Unilock Service
Colton’s homes sit on ground that moves. North-side lots near the San Bernardino foothills shift with every winter rain and summer drought cycle, and plenty of Unilock driveways and patios in this city were installed by crews who never accounted for that movement. Our crews have cut apart enough heaved Brussels Block and settled U-Cara walls in Colton to know what holds and what gives. Rick Sondermann, our owner, grew up in Corona del Mar and has spent nearly three decades building and renovating across Southern California; he learned at Saddleback College that the first thing to get right is what’s under the surface. That’s why every job starts with a base and drainage assessment, not a paver count. We source genuine Unilock units and matching edge restraints for color consistency, and we use quality aftermarket polymeric joint sand and geotextile where the spec allows. You get straight answers about whether your base is worth saving or needs to be rebuilt. If you’re in Colton, we’re nearby and ready to look at your project.

Common Unilock Construction Problems We Solve in Colton
- Efflorescence blooming on Brussels Block and Beacon Hill pavers. Winter rains in Colton wick moisture up through expansive clay sub-bases, leaving chalky white mineral deposits on the paver surface. The bloom itself is cosmetic, but it signals a drainage problem underneath that will only get worse in the wet years.
- Edge spalling and face cracking from UV and heat cycling. When pavers are set on a base placed during a dry Santa Ana spell and never re-compacted, the surface shifts slightly every time the temperature swings 40 degrees in a day. Edges chip, faces crack, and the joints open up.
- Joint sand washout and rutting on driveways. Over Colton’s shifting clay, base prep that skipped geotextile separation lets fines pump up between units. The first storm washes out the sand, and within a season the driveway ruts where tires track.
- U-Cara retaining wall settlement and cap shifting. Footings dug too shallow for the swell-shrink movement near the foothills cause walls to lean, caps to slide, and the wall’s face to separate. This is a structural problem, not a paver problem.
- Whole-surface failure from a compromised subgrade. The most common issue we find is that the pavers themselves are fine; the clay underneath never was. Re-sanding a surface on failed expansive clay is a temporary fix at best.
Unilock Service in Colton: What Local Conditions Mean for Your Equipment
Colton’s north-side lots near the San Bernardino Mountain foothills sit on expansive clay that swells with winter rain and shrinks through 100°F summers. A generic Unilock page won’t tell you this, and neither will a Colton General Contractor without paver-specific experience. What we know from reclaiming failed paver installations here is that the paver itself is rarely the culprit. On a sloped lot off the north foothill edge, we pulled up a heaved Brussels Block driveway where the original builder had set pavers on barely compacted native clay. We excavated to a deeper compacted aggregate base, added geotextile separation and a drainage swale toward the street, then re-laid the pavers with fresh edge restraint and polymeric joint sand. The surface has held flat through two rain seasons instead of rutting at the first storm. That’s the standard for Unilock work in Colton: engineered base depth, real drainage, and a paver laid the way Unilock’s spec intends. Colton’s pre-1980s homes also tend to hide aluminum wiring and underslab plumbing, which matters when a driveway rebuild uncovers what’s underneath and we need to coordinate with other trades. That’s our full-scope approach carrying its weight.
Unilock Models & Products We Service in Colton
We install and repair the full range of Unilock systems most common in Colton: Brussels Block, Beacon Hill, Onyx, and the U-Cara retaining wall line. When a paver needs to be matched dimensionally and by color, we source genuine Unilock units so a patio patch doesn’t look like a patch. In cases where OEM parts aren’t available for older production runs, we use aftermarket options that meet the same dimensional spec, and we’re upfront about the difference. Edge restraints are sourced to match the existing system’s profile. For faster turnaround in Colton, we keep common polymeric joint sands and geotextile in our regional supply chain so we’re not waiting on a truck from back east before a rebuild can start. The truth we’ll tell you plainly: if the base and drainage are sound, repair is the right call. If the subgrade has failed on expansive clay, rebuilding is the only honest recommendation.

FAQs – Unilock Construction in Colton
The clay soil on Colton’s north side near the foothills swells when it rains and shrinks in the heat, and a base built without that movement in mind will push pavers around with it. The fix is a deeper compacted aggregate base with geotextile separation. We see this constantly. Call (855) 473-6535 and we’ll assess your base and tell you what it needs.
Heat and UV don’t damage the paver itself in a way that requires replacement, but they do stress the base and the joint sand. Daily temperature swings cause micro-movement, and if the base was never fully compacted, those swings show up as spalling edges and cracked faces over time.
Yes, we source genuine Unilock Brussels Block units and match color and dimensions as closely as the current production run allows. We’re upfront about any color drift between older installed pavers and a fresh pallet, and we’ll show you samples before we commit.
On Colton’s expansive clay, we plan for a minimum of 6 to 8 inches of compacted aggregate base over a geotextile separation layer, deeper where drainage or slope demands it. Anything less on the north side is a driveway that will rut by spring.
Many Colton lots near the foothills need some form of retention to keep a paver surface stable, especially if the grade drops more than a foot or two across the yard, and our Unilock service in Rubidoux handles similar terrain challenges. We’ll tell you if your slope is manageable on grade or if a U-Cara wall has to be part of the scope.
