Unilock Construction in Highgrove, CA | Polaris Contractors
We install, repair, and replace Unilock paver driveways, patios, and retaining walls throughout Highgrove. The single biggest thing that sets our Unilock work apart here is how we handle the base: Highgrove’s expansive clay makes paver work a base-reconstruction job first, a surface job second. Whether it’s a Brussels Block driveway or an Estate Wall that’s bowing, our crew at Polaris Contractors knows exactly what this soil does to hardscaping. Call (855) 473-6535 for a free estimate on any Unilock project in Highgrove.
We’re an independent contractor serving all of Highgrove service area ZIP 92313. Not authorized by Unilock, but deeply experienced with their product lines. More on that below.
Why Highgrove Residents Choose Us for Unilock Service
Here’s the honest version: any paver installer can drop stone on sand. The difference is knowing what’s underneath, and Highgrove doesn’t let you guess. Rick Sondermann, our owner, learned the fundamentals at Saddleback College in Mission Viejo and has spent nearly three decades in residential construction across Southern California. The lesson that stuck: the foundation decides whether the surface lasts.
Our crew has installed and repaired Unilock hardscapes across the Inland Empire for years, from Unilock in Grand Terrace to Highgrove, and we know how their segmental retaining wall and paver systems perform in Highgrove’s expansive clay and 100°F summers. We stock genuine Unilock replacement units and OEM-approved polymeric sand for fast turnarounds. When you call us, you get a straight answer about whether your project needs a re-level, a partial rebuild, or a full tear-out. No drama, just useful information.
We’re a full-scope general contractor, which matters more than it sounds. A Unilock patio is rarely just a patio. It drains toward your foundation, it meets your fence line, it wraps around the garden wall. One team handling the whole property means the paver work actually fits the rest of the home. From the roof down to the pavers, we manage the entire scope.

Common Unilock Construction Problems We Solve in Highgrove
Highgrove has a particular way of testing hardscape. Here’s what we see most often:
- Efflorescence and white salt staining on Brussels Block pavers. Highgrove’s low rainfall combined with irrigation overspray leaves mineral deposits that get pulled to the paver surface as water evaporates. It’s especially visible on darker Unilock colors. We remove it with the right chemical treatments and adjust the drainage that causes it in the first place.
- Paver settlement and lippage over expansive clay. This is the big one in Highgrove. The clay expands when damp and contracts when dry, so pavers laid on an undersized base will start to settle unevenly within a few seasons. If your paver edges are trip hazards, the base failed. We rebuild it.
- Estate Wall block cracking or bowing on sloped lots. Many Highgrove properties have grade changes. When a Unilock Estate Wall goes up without proper drainage behind the wall face, water pressure builds up during irrigation season and pushes the blocks forward. We see bowing walls on the rural parcels all the time, and the fix is always drainage and reinforcement, not just re-stacking.
- Color fading and surface spalling on older Unilock pavers. Highgrove summers regularly top 100°F with intense UV exposure. Older Unilock units lose surface pigment over years of direct sun. You’ll see faded centers on patios where pavers were cut from different production runs. We match replacement units carefully, but faded fields sometimes need a full replacement to look right.
- Polymeric sand failure in Highgrove’s heat and low rainfall. Joint sand that’s never activated properly, or is the wrong type for the joint width, breaks down faster here. Dusty, crumbling joints let weeds take hold and pavers shift. We use Unilock-approved polymeric sand rated for inland climates.
Unilock Service in Highgrove: What Local Conditions Mean for Your Equipment
Here’s something most paver companies won’t tell you: Highgrove’s unincorporated county parcels, like many we see providing Colton Unilock service, often have older driveways and patios poured directly on grade without proper base compaction. They were built in the 1950s through 1970s, long before anyone thought about what expansive clay would do over 60 or 70 years. So a Unilock paver project here frequently requires full base reconstruction, not just a surface overlay. You can’t simply lay new pavers over a cracked slab and expect it to hold.
We learned this the hard way for you. On a half-acre parcel off a rural lane in Highgrove, we tore out a cracked 1970s concrete driveway and installed a new Unilock Brussels Block paver driveway with a compacted aggregate base and edge restraints. The original slab had heaved from clay movement, so we excavated 8 inches, re-graded for drainage, and set the pavers with polymeric sand. The homeowner now has a stable, repairable surface that handles the summer heat and winter rains without the cracking they had before. That’s what a proper base buys you.
Unilock Models & Products We Service in Highgrove
We work with the Unilock product lines most common in Highgrove and the broader Inland Empire: Unilock Brussels Block, a tumbled-edge paver popular for driveways and patios; Unilock Beacon Hill, a flagstone-textured paver for walkways and pool decks; Unilock Estate Wall, a large-format segmental retaining wall block; and Unilock Pisa2, a smaller profile retaining wall unit commonly used for garden walls and short grade changes.
For repairs, we source genuine Unilock replacement units to maintain color and dimensional match. Aftermarket pavers from other manufacturers never match the chamfer, texture, or color blend of original Unilock product, and it shows. For joint sand and edge restraints, we use OEM-approved products. Our full-scope team also handles the accompanying work: fence lines that meet the paver edge, drainage that keeps water moving away from the house, and any structural adjustments needed under the hardscape.

FAQs – Unilock Construction in Highgrove
Yes, but only with a properly engineered base. Highgrove’s clay expands and contracts enough to crack rigid materials, so we excavate to stable depth, compact an aggregate base, and sometimes add geotextile fabric to isolate the structural layer. Skip the base work and the pavers will settle within a few seasons. Call (855) 473-6535 for a site evaluation before you commit to any quote.
Intense UV and 100°F+ summers fade older Unilock paver surfaces over time, and heat accelerates joint sand breakdown—something we address with Unilock service in Rubidoux and throughout the region. We specify UV-stable polymeric sand and match replacement pavers to current production runs. A patio that’s been baking in Highgrove sun for 15 years will never perfectly match a new paver, but we’ll get it close and be honest about it.
Most Highgrove driveway replacements with Unilock pavers run $7,000 to $18,000, depending on size and base condition. If we’re tearing out an old concrete slab that’s heaved from clay movement, plan for the higher end. Get exact numbers by calling (855) 473-6535 for a free estimate.
Yes. We repair bowing Estate Wall and Pisa2 units by reconstructing the wall face, adding proper drainage behind the wall, and reinforcing with geogrid where the slope requires it. If the wall has shifted beyond repair, we’ll tell you honestly and quote a rebuild instead of patching a failing structure.
