Unilock Construction in Highgrove, CA | Stallion Contractors
We provide independent Unilock in Grand Terrace and nearby Highgrove, handling paver and wall installation, repair, and replacement. The one thing that separates our Unilock work here from what you’ll get with a crew out of Riverside or San Bernardino: we know how Riverside County’s unincorporated permitting and Highgrove’s expansive soils change the way a paver system has to be built. Stallion Contractors is not authorized, sponsored, or endorsed by Unilock. We’re a full-scope general contractor who has installed and repaired enough Unilock product in the I-215 corridor to know exactly where these systems fail and why. Call (855) 600-3192 to talk through your project or get a free estimate.

Why Highgrove Residents Choose Us for Unilock Service
Unilock makes a good paver. But a paver is only as good as the base under it. In Highgrove, where clay soil swells and shrinks with every wet-dry cycle, the base is everything. We build bases that handle that movement without cracking, shifting, or settling into a wavy mess two summers later. Ruben Montoya, our owner at Stallion Contractors, grew up in Colton and spent two-plus decades working Inland Empire soil before he ever put his name on a hardscape project. He’s seen what cheap base work does on these lots, and he’d rather walk you through exactly what your project needs than let you find out the hard way.
We’re a general contractor, not a one-trade hardscape shop. That means when your Unilock patio ties into a roof drain, a retaining wall, or a driveway approach, the same crew handles it all. One contractor. Every trade. The materials come from our network of 50-plus vetted brand partners, which includes Unilock for hardscaping alongside names like Cambria, GAF, and James Hardie for the rest of the home. Pro-grade materials, professionally installed.
For an honest look at what your project needs, call us at (855) 600-3192. Estimates are free, and we’ll tell you straight whether repair makes more sense than replacement.

Common Unilock Construction Problems We Solve in Highgrove
- Efflorescence on Brussels Block pavers. That white, chalky film on your Brussels Block patio is salt deposits wicking up through the paver. Highgrove’s irrigation water and alkaline soil make this common. We clean and reseal the affected area, and if the source is poor drainage beneath the pavers, we fix that too, because sealing over a drainage problem just moves the stain somewhere else.
- Base failure and settlement in Estate Wall segments. Highgrove’s expansive clay pushes and heaves when it gets wet. Walls built on shallow, uncompacted base start leaning or cracking within a few seasons. We rebuild the base with compacted aggregate, add drainage behind the wall, and reset the blocks. A wall that’s just patched will fail again.
- Paver shifting and edge restraint failure near washes. Seasonal flash floods in Highgrove’s drainage areas move water fast. Without proper edge restraints and on-site retention, pavers shift, spread, and sink at the edges. We reinstall with edge restraint systems rated for the load and re-grade so water actually goes where it should.
- Color fading and surface wear on Beacon Hill pavers. Highgrove’s UV exposure is relentless, and Santa Ana winds add abrasion. Older Beacon Hill installations lose their color depth and start looking tired. We can match the original Unilock blend in most cases and replace only the damaged section, or resurface the full area if the wear is widespread.
- Driveway paver movement under vehicle load. A paver driveway that wasn’t built over the right base depth will rattle and shift under daily traffic. On Highgrove’s rural lots, where driveways tend to run long, that’s a lot of paver to redo. We assess the base, not just the surface, and we’ll only recommend full replacement when the base is truly done.
Unilock Service in Highgrove: What Local Conditions Mean for Your Equipment
Here’s what nobody tells you about installing Unilock hardscape in Highgrove: because the community is unincorporated, any project that changes drainage or adds impervious cover can trigger Riverside County flood-control review. That applies to paver driveways and large patios, not just structures. Inside the City of Riverside, a contractor pulls a building permit and moves on, while Unilock service in Rubidoux faces similar county requirements. In Highgrove, the county looks at your entire parcel, the nearby washes, and how your new paver surface changes water flow across your land and your neighbor’s. If the drainage plan doesn’t pencil out, the design has to change before we can install. We’ve done enough of these county reviews to know how to design paver systems that pass the first time, and for properties off Center Street or any of the older mid-century lots, that extra step often dictates whether you need on-site retention or modified grading. It’s not red tape for its own sake. It’s the county making sure the next flash flood doesn’t take your pavers with it.
On a property off Center Street in Highgrove, we repaired a failing Unilock Estate Wall that had settled due to poor drainage and expansive soils. The homeowner called us because the wall had a visible crack running through three courses of block. We rebuilt the base with compacted aggregate, added a French drain behind the wall, and reset the blocks with proper geogrid reinforcement. The fix held because we addressed the root cause, not just the crack. That’s the difference between patching and repairing.
Unilock Models & Products We Service in Highgrove
We install and repair the Unilock lines most common in Highgrove yards: Brussels Block, Estate Wall, Beacon Hill, and Pisa2. Brussels Block is the pick for patios and walkways where you want a classic tumbled feel. Estate Wall is the segmented retaining wall you see holding back slopes on the larger rural lots. Beacon Hill is the driveway paver for vehicle loads. Pisa2 is the dimensional wall block that works well for planters and seat walls.
When we repair existing Unilock installations, we source genuine Unilock replacement units whenever they’re available, so your new pavers match the old ones in color and dimension. We also use compatible OEM accessories and high-quality aftermarket base materials and polymeric sands that meet or exceed Unilock specifications for this region’s conditions. If a specific Unilock blend is discontinued, we’ll tell you that upfront and show you the closest match before any work starts.

FAQs – Unilock Construction in Highgrove
Most likely yes. Because Highgrove is unincorporated, Riverside County Building & Safety reviews paver driveway projects, and if the work changes drainage or adds impervious cover, the county’s flood-control division gets involved too. A paver patio may not need a building permit if it’s small and doesn’t alter drainage, but we check before we quote. Call (855) 600-3192 and we’ll tell you what your specific site will need.
That’s efflorescence, salt deposits left behind when water moves through the paver and evaporates at the surface. In Highgrove, the alkaline soil and irrigation water load the rising moisture with minerals, so the white film shows up more than it would in other areas. We clean and seal the surface, and if the moisture source is trapped water under the pavers, we address the drainage so the problem doesn’t return. Call (855) 600-3192 for an assessment.
We don’t just reset the blocks. We pull the wall, rebuild the base with compacted aggregate, install drainage behind the wall, and reset the blocks with proper geogrid reinforcement. Highgrove’s expansive clay is what causes the settlement in the first place, so skipping the base and drainage work means the wall will fail again, something we also address with Unilock repair in Loma Linda. Call (855) 600-3192 for a free estimate.
For driveways, Beacon Hill is built for vehicle load and holds up well under our UV. For patios, Brussels Block gives you a dense surface that handles foot traffic and looks right on Highgrove’s larger lots. The more important variable is the base and edge restraint system, which is what actually survives a flash flood. We design both to county drainage standards. Call (855) 600-3192 to talk through your site.
Usually yes. We keep common Unilock blends accessible and source genuine replacement units when the model is still in production. If your particular blend has been discontinued, we’ll match the closest available option and show you a sample before we install. Call (855) 600-3192 and we’ll check your paver against current Unilock stock.
