Unilock Construction in Highgrove, CA | Square One Builders
We install and repair Unilock paver driveways, patios, and walkways across Highgrove, including Brussels Block, Beacon Hill, Copthorne, and Town Hall product lines. What sets our Unilock work apart here is that we treat every job as a site-specific civil problem: Highgrove’s unincorporated Riverside County status means grading, septic setbacks, and well-line locations dictate the engineering before a single paver gets set. If you’re planning a paver project or your existing Unilock surface is shifting, call us at (877) 688-9930 for a free estimate.

Why Highgrove Residents Choose Us for Unilock Service
Our crew has installed and repaired Unilock pavers on Highgrove’s irregular, acreage lots long enough to know how Riverside County permitting, septic setbacks, and intense heat exposure affect base prep and joint sand. We’re an independent Unilock service provider, not a manufacturer-authorized dealer, which means we’re free to recommend what actually works for your lot rather than what a brand rep wants pushed. We also offer Colton Unilock service for properties just west of here. Brent Calloway, our owner and general contractor, spent his early years in Orange County’s Midway City pocket learning framing and concrete the ground-level way, and that same instinct against cutting corners drives how we build every paver base in Highgrove. We use Unilock OEM color-matched joint sand and edge restraint where warranty consistency matters, and quality aftermarket base aggregates and geotextiles where the brand doesn’t specify. One contractor, every system, from the base up.

Common Unilock Construction Problems We Solve in Highgrove
- Efflorescence blooming on Brussels Block and Beacon Hill pavers. Highgrove’s mineral-heavy well water leaves white calcium deposits on paver faces after summer irrigation cycles. We clean the surface, address drainage that keeps the pavers damp, and apply a breathable sealer so the bloom doesn’t return in six months.
- Joint sand washout and paver shifting on sloped driveways. Santa Ana winds strip loose joint material, and rain channels off unpermitted grade changes cut paths through the sand. We re-sand with polymeric material, fix the grade where the county allows, and set edge restraint that actually holds.
- Edge restraint failure near septic leach fields. Soil movement around leach lines undermines the compacted base and pushes paver edges outward on Highgrove lots where the septic system sits close to the driveway or patio. We excavate to stable soil, rebuild the base in lifts, and use heavier edge restraint.
- Color fading and surface pitting on older Copthorne and Town Hall units. Sustained 100°F+ heat and UV exposure without proper sealing breaks down the paver face over time. We assess whether the units are structurally sound and, if so, clean, re-sand, and seal rather than pushing full replacement.
- Base failure from poor initial compaction. On larger, irregular Highgrove lots where original installs were done by crews unfamiliar with expansive inland soil, the base settles and the pavers follow. We pull the affected area and rebuild rather than patch over the problem.
Unilock Service in Highgrove: What Local Conditions Mean for Your Equipment
Because Highgrove is unincorporated Riverside County, Unilock driveway and patio projects here require county grading and right-of-way approvals rather than a city permit. That’s not a small distinction. On lots with private wells and septic systems, we must locate and protect underground utilities before any base excavation begins, and the county plat doesn’t always match what’s actually buried. On a ranch property off the Center Street corridor, we tore out a failing asphalt drive and installed a Unilock Brussels Block driveway, but first had to hand-dig around a septic line the county plat didn’t show. We re-compacted the base in lifts to account for the slope, set OEM edge restraint, and finished with polymeric sand, then sealed it after a 10-day cure window to survive the next Santa Ana event. That’s the Highgrove difference: the paver pattern matters less than what’s underneath it, and what’s underneath it here is rarely standard.
Unilock Models & Products We Service in Highgrove
We service the full range of Unilock residential paver lines common in Highgrove: Brussels Block, Beacon Hill, Copthorne, and Town Hall, along with matching edge units and coping. For repairs, we use Unilock OEM color-matched joint sand, edge restraint, and polymeric sand for warranty-consistent work. For base aggregates and geotextiles where Unilock doesn’t specify a branded product, we source quality aftermarket material locally so we’re not waiting on a distributor in Riverside for every load. If your existing pavers are structurally sound, we re-sand and re-level. If the base has failed, we pull and rebuild, start from square one, build it right. Our Unilock sales & service team can identify your specific paver line from a photo before we even schedule the site visit.

FAQs – Unilock Construction in Highgrove
Yes, in most cases. Highgrove’s unincorporated status means Riverside County handles grading and right-of-way approvals, not a city building department, so your paver driveway project needs county sign-off before base work begins. We handle the permit package and coordinate with the county as part of our scope, and we bring the same thoroughness to our Unilock service in Rubidoux. Call (877) 688-9930 and we’ll confirm what your specific lot requires.
The mineral-heavy well water common on Highgrove acreage properties leaves calcium deposits on paver faces, especially Brussels Block and Beacon Hill units after irrigation cycles. We clean the surface, fix the drainage that keeps pavers damp, and seal with a breathable product so the bloom doesn’t return. An exact quote is free; call (877) 688-9930.
Not over an active leach field, no. Riverside County requires setbacks between hardscape and septic components, and most Highgrove lots need the leach lines located and marked before we can design the patio. We’ll work around the system, not on top of it, and pull the county’s septic records as part of your estimate. Call (877) 688-9930 to walk the site with us.
Copthorne and Town Hall units wear the intense heat better than lighter-colored lines, but the real answer is base preparation and polymeric sand with edge restraint. The paver is only as stable as the base beneath it, and Highgrove’s loose, wind-scoured topsoil means we compact in lifts and set restraint on every open edge. Call (877) 688-9930 for a paver selection that fits your lot.
We repair first. If your pavers are structurally sound, we re-sand, re-level, and seal. If the base has failed, meaning the pavers are shifting, sinking, or the edges are spreading, we pull and rebuild the section properly rather than patching over it. Either way, you’ll get a straight answer on what’s fixable and what isn’t. Call (877) 688-9930 for an honest assessment.
