Unilock Construction in Highgrove, CA | Moreno Valley Builders
We install and repair Unilock paver driveways, patios, and retaining walls across Highgrove, and the one thing that separates our work here from anywhere else is soil. Highgrove sits on expansive adobe clay that heaves in winter and shrinks in summer, and a Unilock system built to survive that movement needs engineered base prep, perimeter drainage, and a permit set that goes through Riverside County, not a city counter. If you’re pricing a Unilock driveway, patio, or wall in the 92313 ZIP, call (877) 752-3154 for a free site evaluation. This is our Unilock sales & service specialty, and we’ve been doing it long enough to know what fails here and why.
We’re an independent contractor. Not Unilock-authorized, not manufacturer-sponsored. That independence means we tell you plainly when a base is worth saving, when it’s not, and which material actually belongs under your pavers given what a Highgrove General Contractor knows its ground does every wet and dry season.
Why Highgrove Residents Choose Us for Unilock Service
Noel Trevino grew up in Sunnymead Ranch and has spent nearly three decades building across the Inland Empire. He’s pulled out enough cracked Unilock Brussels Block driveways on Highgrove’s adobe lots to know that the paver itself is rarely the problem, and that same experience informs our Colton Unilock service. The problem is almost always what’s underneath. We bring that same read-the-soil-first approach to every Unilock patio, driveway, and retaining wall we touch in Highgrove.
We stock and source genuine Unilock pavers, wall units, and accessories when the original profile is still in production. When a color has been discontinued, we pull a base sample and match it as closely as possible with a quality domestic hardscape product. You’ll know which route applies to your job before we start, and you’ll see the numbers in writing. Our Highgrove service area coverage means short site-visit turnaround, and because we know the local permitting path, we don’t burn your time on avoidable plan-check corrections.

Common Unilock Construction Problems We Solve in Highgrove
- Cracked and heaved Brussels Block pavers on driveways. Expansive adobe clay swells with winter moisture and shrinks hard in summer. That movement cracks pavers and snaps the edge restraints on driveways installed over thin, non-engineered base. We see this constantly on older Highgrove properties.
- Rutting and rocking patio pavers with joint sand washout. Storm runoff with nowhere to go undermines the compacted base under Unilock patios. The pavers then rock, the rutting starts, and polymeric sand disappears from the joints. Without a drainage fix, no re-sanding job holds.
- Failing joint sand and loose step caps on Beacon Hill Flagstone installs. A lot of Highgrove’s 1990s-to-2000s Unilock Beacon Hill work went in over base that was never designed for shrink-swell soil. The caps loosen, the joint sand breaks down, and the topography of the patio starts drifting.
- Bulging or leaning Thornbury retaining walls. Thornbury wall blocks installed without geogrid and proper drainage lean after a few wet-dry cycles. On Highgrove’s sloped semi-rural parcels this happens faster than you’d think, and the fix is never just pushing the wall back.
- Sun-baked fading and surface wear on south-facing Unilock patios. Highgrove’s inland heat and the 92313 ZIP’s long, dry summers beat down on pavers year after year. UV and heat accelerate surface wear, especially on older Unilock lines that predate today’s color-stable blends.
Unilock Service in Highgrove: What Local Conditions Mean for Your Equipment
Highgrove isn’t Riverside. It isn’t Grand Terrace. It’s an unincorporated Riverside County island, and that changes the construction paperwork every time. A Unilock paver driveway or patio that would be permit-exempt in neighboring incorporated cities goes through the full County of Riverside Building & Safety plan review and inspection process here. That’s not a trivial distinction. It means your hardscape plans need to account for expansive adobe soils in a way that a city building department across the boundary might never ask for.
We’ve worked through enough of those County submittals to know what the reviewers look for on a Highgrove parcel. Engineered base sections. Geogrid where the soil report calls for it. Perimeter drainage that actually moves water off the pad. If the details aren’t right on paper, they won’t be right in the wall. And on a semi-rural parcel off Spring Street in Highgrove, we rebuilt a heaved Brussels Block driveway that had cracked and shifted after years of adobe movement. We removed the failed base, installed a geogrid-reinforced aggregate section with a perimeter drainage channel, and re-laid the pavers with new edge restraints and polymeric joint sand. That driveway now sits tight through summer cracking and winter storms. The same job across the line in Grand Terrace might never have needed the County stamp, but here it’s the only way a Unilock driveway survives, as we know from providing Unilock service in Rubidoux and nearby communities.
Unilock Models & Products We Service in Highgrove
We work on the Unilock lines that show up most often on Highgrove’s mid-century ranch lots and semi-rural parcels: Brussels Block pavers for driveways, Beacon Hill Flagstone for patios and walkways, Thornbury for retaining walls, and Brussels Dimensional Stone wall units for planter walls and seat walls. If your installation is older and the original Unilock color is still in production, we source it directly. If it’s discontinued, we don’t pretend otherwise. We pull a base sample, match the profile and color as closely as possible with a proven domestic line, and show you the comparison before anything gets ordered. For fast Highgrove turnaround, we keep common joint sand, edge restraints, and base aggregates staged locally so the site work isn’t waiting on a materials truck.

On a Highgrove job, the big cost drivers are site prep and base work, not the pavers themselves. If the adobe soil is compromised, the base has to be rebuilt with proper drainage and sometimes geogrid. That’s labor and material up front, but it’s the only way the pavers hold. Skip it and you’ll be calling us back in three years. Our free estimate includes a site walk, a soil read, and a written line-item quote. Call (877) 752-3154 to schedule yours. We’ll tell you straight whether a repair makes sense or a full rebuild is the only honest route.

FAQs – Unilock Construction in Highgrove
In most cases, yes. Because Highgrove is an unincorporated Riverside County island, hardscape work that wouldn’t trigger a permit in Riverside or Grand Terrace often requires County of Riverside Building & Safety plan review and inspection here. That’s especially true for driveways, retaining walls, and any project with drainage implications on expansive soil. We handle the permit package, the engineering coordination, and the inspections as part of the job. Call (877) 752-3154 and we’ll tell you early whether your specific project needs a permit.
Highgrove’s expansive adobe clay is the culprit. The soil swells when wet and shrinks when dry, which puts constant movement stress on any rigid paver installation. If the base underneath wasn’t engineered for that shrink-swell cycle, the pavers crack, the edge restraints break, and the surface starts to heave and rut. The fix is always in the base and drainage, never in simply swapping out cracked pavers.
If your Brussels Block color and profile are still in production, yes, we source genuine Unilock units to match. If the line has been discontinued, we pull a base sample and match the color and profile as closely as possible with a quality domestic hardscape product. We show you the comparison before ordering. Call (877) 752-3154 for a free match evaluation on your Highgrove property.
Significantly. On stable, well-drained ground, base prep is straightforward. On Highgrove’s expansive adobe, we frequently have to over-excavate, install geogrid reinforcement, and add perimeter drainage to prevent future heave and settlement. That adds material and labor compared to a job in a neighboring city with more forgiving soils. It’s also the difference between a patio that lasts decades and one that fails in five years. Call (877) 752-3154 for an exact quote, estimates are free.
