Unilock Construction in Highland, CA

Unilock Construction in Highland, CA | Square Deal Contractors

We install and repair Unilock paver driveways, patios, and retaining walls across Highland, CA. The factor that separates a Unilock installation that stays flat and true on a Highland hillside from one that heaves and shifts within two seasons comes down to how the base was built on your specific lot’s decomposed granite subgrade. We’re an independent contractor crew, not a Unilock dealer or authorized affiliate. We simply know the product line and install it to spec on terrain most valley-floor installers never deal with.

Why Highland Residents Choose Us for Unilock Service

Highland’s housing stock climbs from mid-century ranch homes near the valley floor up into newer custom hillside builds. That means we see two very different Unilock installation scenarios in the same ZIP code. The flat lots need disciplined base prep. The foothill lots need over-excavation, geogrid, and drainage planning before the first paver gets set.

Nolan Breckett, our owner, grew up in the Baker Ranch area of Lake Forest and spent three decades learning construction the way it actually goes, including the construction technology program at Saddleback College. He’s straight about what a Highland lot needs and what it doesn’t. We don’t reuse a valley-floor base spec from a Redlands job and hope it holds on a sloped Highland parcel. We dig, we test what’s under the surface, and we build the base your specific soil demands. We’re also an established Unilock sales & service resource for homeowners who want genuine product knowledge without a manufacturer’s showroom script.

Common Unilock Construction Problems We Solve in Highland

Here’s what we’re called to fix most often in Highland, and why it happens here specifically:

• Efflorescence on Brussels Block and Cambridge pavers. Highland’s winter rains can be intense when they arrive, and after hard soaking, salts wick up through the joint sand and leave chalky white residue on the paver face. We clean it properly and address the drainage that feeds it.
• Polymeric sand washout on sloped driveways. When runoff concentrates before reaching a drainage channel, it scours the joints right out. On Highland hillside driveways this is a repeat offender. We re-grade the slope break, add the channel where it belongs, and re-sand with quality polymeric.
• Pisa2 retaining wall courses leaning or bulging. Set a segmental wall on decomposed granite without proper geogrid and compacted aggregate, and it will lean. We see this on hillside lots throughout Highland where the original installer treated DG like stable valley soil.
• ArmorTec face spalling and edge chipping. Highland’s rocky foothill subgrade sits close to the surface. Bed pavers too thin over rock that wasn’t over-excavated, and the paver edges chip under load. We remove, excavate, and set on a proper compacted base.
• Heaved paver fields after heavy rain cycles. Saturated DG expands and shifts. Without a clean aggregate base, a Unilock driveway on a Highland hillside will move. We rebuild it so it stays put.

Unilock Service in Highland: What Local Conditions Mean for Your Equipment

Highland sits on decomposed granite and rocky foothill soil that changes dramatically from parcel to parcel, even within a few hundred feet. A Unilock paver or wall base that was fine on one street can fail on the next because the subgrade is entirely different. Crews that assume uniform valley soil, like you’d find with Unilock in San Bernardino, get surprised at inspection or shortly after. So we over-excavate and re-compact per lot, not per template. One job off the foothill edge near the national forest boundary taught us this the hard way: a heaved Brussels Block driveway where the original crew had bedded pavers directly over DG with almost no base. We pulled the whole field, over-excavated, brought in compacted aggregate, added a drainage channel at the slope break, and re-laid fresh Brussels Block with polymeric sand. That driveway has held through two Santa Ana seasons since. Know what you’re getting into before the first nail goes in, and around here that starts with the dirt.

Unilock Models & Products We Service in Highland

We work with the Unilock lines most common across Highland: Brussels Block, Cambridge Pavingstones with ArmorTec, Beacon Hill Flagstone, and the Pisa2 retaining wall system. For Unilock repair in Muscoy and across Highland, we source genuine Unilock units so the color, dimension, and ArmorTec finish match your existing field. We don’t patch a Cambridge patio with a different manufacturer’s paver and call it close enough. For jointing and base, we use quality polymeric sand and clean aggregate, not whatever bag is cheapest at the big-box. When a wall or driveway has failed structurally, we’ll tell you plainly that re-laying over a bad base just repeats the failure. Repair only makes sense when the subgrade is sound.
