Unilock Construction in Highland, CA | Square One Builders
We provide independent Unilock paver and wall construction across Highland, CA, from flatland ranch lots to hillside parcels along the city’s northern foothill edge. What makes our Unilock work here different is simple: we spec and install based on how Santa Ana wind events, wildland-urban interface requirements, and slope drainage actually behave in Highland, not on what a dealer happens to be pushing that season. If you’re pricing a paver driveway, patio, or retaining wall, call us at (877) 688-9930 for a free estimate.
Is Unilock Right for Highland’s Climate?
Most of the time, yes, but the paver line matters more here than it does in flatland Inland Empire cities. Highland sits where the Cajon Pass funnels Santa Ana winds down from the high desert, and the northern boundary butts against San Bernardino County wildland-urban interface zones. That combination means hardscape gets evaluated for things a Corona or Riverside backyard never has to answer for: ember-resistant surfaces, defensible-space clearance, and runoff control on slope-draining grades. We’ve laid Unilock in San Bernardino County and across enough Highland properties to know which systems hold up and which need extra base prep before the first paver goes down.

Why Highland Residents Choose Us for Unilock Service
We’re a general contractor, not a paver-only shop, and that changes how a Unilock project gets scoped. When a driveway re-lay exposes a drainage problem, we fix the drainage. When a patio field butts against a retaining wall that’s starting to lean, we address the wall—something we handle with Unilock repair in Muscoy and nearby communities too. Brent Calloway, our owner and general contractor, came up doing ground-level work, framing, concrete, and finish carpentry, and that full-scope instinct carries into every hardscape job we take on in Highland. You’re not hiring a paver installer who hopes the rest of the yard cooperates. You’re hiring one accountable team that sees the whole site.
We’re also an independent Unilock service provider, not a manufacturer-authorized dealer. That independence means we recommend the Unilock product line that fits your application and budget, and we source genuine Unilock units matched to your existing series and color when repair work comes up. No one’s telling us to push a particular line because inventory is sitting in a yard.
Common Unilock Construction Problems We Solve in Highland
These are the failure patterns we see most often on Unilock installations across Highland:
- Efflorescence bloom on Brussels Block and Beacon Hill. Highland’s alkaline soils and hard irrigation water leave white mineral deposits on paver surfaces, especially where sprinkler overspray hits the field every morning. It’s cosmetic but persistent, and it typically needs a cleaning and re-sanding approach rather than a quick sealant that traps moisture underneath.
- Base and edge restraint failure on hillside driveways and patios. Winter storm runoff that isn’t graded away from the paver field gets under the edge restraint and starts working the base loose. We see this repeatedly on north Highland properties where a slope drains toward the hardscape instead of around it.
- Joint sand washout after intense winter rain. When polymeric sand was under-applied or the base wasn’t compacted in lifts, the first heavy rain pulls joints clean and pavers start shifting within a season. Two Santa Ana seasons later, the field looks wavy and the edges are spreading.
- Chipping and spalling on U-Cara wall caps and paver edges. Highland’s hot summers followed by cold winter snaps stress the outer surface of wall caps and paver edges. Heavy equipment turning on a driveway edge makes it worse. We see cap units that fracture along the top corner, not through the body of the block.
- Repair-vs-replace decisions gone wrong. When a field has widespread base failure, patching individual pavers doesn’t work. We’ll tell you when a full re-lay is cheaper than chasing individual fixes because the base underneath is the problem. That honesty saves Highland homeowners money over a two or three year period.
Unilock Service in Highland: What Local Conditions Mean for Your Equipment
Highland’s northern boundary runs along the base of the San Bernardino Mountains, and the wildland-urban interface zones there mean hardscape is often reviewed for ember-resistant, non-combustible surfaces and defensible-space clearance. A paver patio or driveway isn’t just a design decision on those properties, it’s part of the fire-defensibility picture. Pavers are naturally non-combustible, which helps, but the spec gets weighed against clearance requirements, slope drainage, and how the hardscape connects to the home’s ignition zone. On a hillside property off the city’s northern foothill edge near Unilock in Redlands territory, we re-laid a failing Brussels Block driveway where storm runoff had undermined the edge restraint and washed out the joint sand. We pulled the field, re-compacted the base in proper lifts, reset the units, re-sanded with polymeric joint sand, and re-graded the swale so winter runoff drains off the drive instead of under it. That surface has held through two Santa Ana seasons since.
Unilock Models and Products We Service in Highland
We install and repair the Unilock lines that perform best in Highland’s climate and terrain. Brussels Block, a tumbled dimensional paver, is our most common driveway and patio unit. Beacon Hill, a flagstone-look paver, works well for patios and walkways where a more natural surface fits the hillside aesthetic. Town Hall handles structural and permeable applications where runoff management matters. For retaining walls, we spec U-Cara, a segmental wall system that holds slopes along foothill-edge lots.
On the parts side, we source genuine Unilock units matched to your existing series and color so repairs blend rather than patch. We also use quality polymeric joint sand and commercial-grade edge restraint rather than bargain substitutes. What we stock locally varies by project, but we handle procurement for every job so Highland homeowners aren’t chasing down matching units themselves.

FAQs – Unilock Construction in Highland
No. We’re an independent Unilock service provider, which means we recommend product lines based on what your Highland site actually needs, not what a dealer program is incentivizing. We source genuine Unilock units for every install and repair, and we’re transparent about OEM versus aftermarket parts throughout the project.
Yes. When matching existing pavers or wall units, we source genuine Unilock units in the same series and color so repairs blend with the original field. For joint sand and edge restraint, we use commercial-grade polymeric sand and hard edge restraint, not the bargain products that fail after one Highland winter.
Highland’s hot inland summers speed up the curing process for base materials and can make polymeric sand activation tricky if installers don’t account for surface temperature. We schedule paver work for the cooler parts of the day during peak summer months and adjust the sand activation process so joints set correctly rather than flash-curing and failing later. The heat doesn’t stop the work, it just changes how careful we have to be about timing. Call (877) 688-9930 and we’ll walk you through the best window for your project.
We install and repair Brussels Block, Beacon Hill, Town Hall, and U-Cara across Highland. Each has different strengths: Brussels Block for driveways, Beacon Hill for patios, Town Hall for structural or permeable applications, and U-Cara for retaining walls on sloping lots. If you have an existing Unilock field we didn’t install, we can usually match the line and repair it.
Driveway replacement in Highland typically runs $5,000 to $14,000 depending on the condition of the existing base, whether drainage work is needed, and which Unilock line you choose. A paver driveway installation from scratch ranges $7,000 to $18,000. Hillside properties with runoff issues land higher. Call (877) 688-9930 for an exact quote, estimates are free.
