Unilock Construction in Highland, CA | Alder Contractors
We provide independent Unilock paver installation and repair across Highland, and the one thing that separates our work here from a flat-lot paver job is slope. Highland sits at the foot of the San Bernardino Mountains, so nearly every hardscape we touch has to account for fast winter runoff, wind-driven joint sand loss, and wildland-edge fire code that flatland neighbors never think about. We’re led by Nelson Ibarra, an Inland Empire builder who’s spent decades working these foothills, and we carry a full lineup of Unilock pavers for patios, driveways, and walkways. Call (833) 467-7020 for a free estimate.
Why Highland Residents Choose Us for Unilock Service
We’ve been installing Unilock systems in Highland long enough to know exactly how Brussels Block behaves after five summers of 100-degree heat, and what Cambridge Cobble does when Santa Ana winds strip the joint sand out of a driveway. That kind of local familiarity matters more in Highland than it does on the valley floor, because the foothill geometry here punishes shortcuts. We’re an independent installer, not an authorized Unilock dealer, and we buy their product on the open market just like any homeowner would. That keeps our recommendations straight: when a Unilock system fits the site, we say so, and when a different base or drainage approach will hold up better, we tell you before we ever lay a paver. Our Unilock sales & service work covers the full Highland service area, from the valley-floor tracts to the hillside lots off the 330.
Nelson Ibarra grew up in the Willow Avenue corridor of Rialto and got his trade grounding at Chaffey College before spending the better part of three decades on Inland Empire job sites. His rule applies to every paver job we take: do it right the first time, because the callback always costs more than the extra hour up front.

Common Unilock Construction Problems We Solve in Highland
Most Unilock failures in Highland don’t start with the paver itself. They start with what’s underneath it and what’s happening around it. Here’s what we pull up on a regular basis:
- Wind-driven joint sand washout on driveways and patios. Highland’s Santa Ana winds don’t just dry things out; they physically strip the fine material from paver joints. Once that sand goes, the pavers lose lateral support and start to wander. We see this most on east-facing driveways and exposed patios near the foothill benches, and we fix it with a proper re-sand and edge restraint, not a quick sweep-in that’ll blow out again by October.
- Efflorescence bloom on Brussels Block and Cambridge Cobble. Highland’s irrigation water runs hard, and when that water wicks up through pavers and evaporates under intense inland sun, it leaves a white mineral crust on the surface. It’s not structural, but it’s ugly, and most homeowners assume the paver is failing. We clean it correctly and adjust the drainage so water stops cycling through the paver bed.
- Hairline cracking and corner spalling from shallow base prep. Much of Highland sits on alluvial-fan soils that expand and shift seasonally. Lay pavers on a thin base of sand over that soil and you get cracked corners within two or three winters. When we find this, we don’t patch. We lift the affected field, re-excavate to the proper depth, and rebuild the base so the pavers stop fighting the soil.
- Edge migration and lippage on sloped patios. The downhill course of a patio loses its line when the grade wasn’t set to move water away from the structure. Puddling against the house leads to freeze-thaw shifting in winter, even in Highland’s mild climate, and the pavers walk out of line. We re-grade, reset, and lock the edge so it doesn’t happen again.
- Hardscape too close to the structure near the wildland edge. Homes backing onto the San Bernardino National Forest foothills face defensible-space requirements, and an old paver patio tight against the wall can become a fire-hardening problem. We review setback and non-combustible perimeter details as part of every estimate in these zones, not as an afterthought.
Unilock Service in Highland: What Local Conditions Mean for Your Equipment
Highland properties near the wildland edge run up against defensible-space and ignition-resistant construction rules that don’t apply on the flat valley floor south of the city. That changes how we detail paver patios here in ways a generic paver crew wouldn’t think to look for. Perimeter materials, non-combustible edging, and how close hardscape sits to the structure all get reviewed with fire hardening in mind, not just drainage. On a Beacon Hill patio job off the foothill side of Highland, our crew found the original install had been laid on a thin base with no positive slope, so winter runoff had pooled against the house and the downhill course of pavers had walked out of line. We pulled the affected field, re-excavated to a deeper compacted base, reset the units with fresh polymeric sand, and re-graded so water sheds away from the structure and the wildland edge instead of sitting against the wall. That’s the difference between a paver job that looks good in spring and one that still looks good after five fire seasons.
Unilock Models & Products We Service in Highland
We work with the Unilock lines that perform best in Highland’s specific conditions: Brussels Block and Cambridge Cobble for their dense surface finish and color stability under heavy UV, Beacon Hill for larger-format patio runs where the scale suits a bigger lot, and Il Campo for a hand-set look that holds up on sloped terrain. When it comes to repairs, we use Unilock service in Loma Linda and our own matching units, edge restraints, and polymeric joint sand where color and dimensional match matter, and quality aftermarket restraint and drainage components where performance beats brand fidelity. For sun-faded, settled, or spalled fields, we tell owners straight whether a targeted lift-and-relay will hold or whether the base needs re-excavation. No sugarcoating; the base is the truth.

FAQs – Unilock Construction in Highland
Yes, but only after the first full year, and only with a penetrating sealer, not a film-forming one. Highland’s sun breaks down film sealers fast, and the dust from Santa Ana winds gets into everything. A penetrating sealer locks the joint sand, slows efflorescence on Brussels Block, and doesn’t peel. We’ll tell you when sealing makes sense and when it’s a waste of money. Call (833) 467-7020 and we’ll walk your driveway and give you a straight answer.
No. We’re an independent installer that buys Unilock pavers on the open market, the same as any contractor or homeowner. That independence means our advice about Unilock products isn’t tied to a manufacturer sales agreement. We recommend Unilock in Redlands and the surrounding area when it fits the site, and we say so when another paver or a different base approach would hold up better in Highland’s foothill conditions.
Most targeted lift-and-relay repairs on a patio or driveway run three to five days, depending on how much of the base needs re-excavation and whether we’re re-grading for drainage. Full paver patio installations typically run one to two weeks, and driveway installations land around two to three weeks. Highland’s foothill lots often add time for slope work and access. We give you a schedule at the estimate, not after you sign.
We install and repair Brussels Block, Beacon Hill, Cambridge Cobble, and Il Campo. Those four lines cover most of the Unilock surfaces in Highland, and we stock matching units and accessories for them locally, which means Unilock repair in Muscoy and color-matched repairs don’t sit waiting on an order from the distributor. If you have a different Unilock line, call us and we’ll match it.
Paver driveway repair in Highland typically runs $500 to $4,000 depending on how much of the field has settled, whether the base needs re-excavation, and whether we’re re-grading for drainage. If the driveway is sun-faded and spalled across the whole surface, replacement lands between $5,000 and $14,000. Call (833) 467-7020 for an exact number; the estimate’s free and it’s the only way to know what your base is actually doing under there.
