Unilock Construction in Upland, CA

Unilock Construction in Upland, CA | Square Deal Contractors

We’re Square Deal Contractors, and we install and repair Unilock pavers, walls, and driveways across Upland. We’re an independent contractor, not a Unilock dealer, which means we recommend the specific Unilock line that fits your lot’s soil and slope rather than whatever the manufacturer is pushing this quarter. The thing that makes our Unilock work different here is simple: Upland sits on expansive clay, and if the base under those pavers isn’t built for that clay, you’ll be repairing it again in three years.

Why Upland Residents Choose Us for Unilock Service

Nolan Breckett grew up in Lake Forest and learned construction sequencing through Saddleback College’s construction technology program, where the instructors drilled one thing into him: the base decides everything. Three decades later, that’s exactly how we approach Unilock work in Upland. We’ve installed Brussels Block driveways off Euclid Avenue, Beacon Hill patios in the 91784 foothill lots, and U-Cara retaining walls on sloped yards where Foothill Boulevard design guidelines dictate the wall’s height and setback. We stock OEM Unilock alignment systems and caps locally so wall profiles match exactly, and we don’t sell tear-outs when a reset and re-sand will do. If you’re researching contractors, our Unilock sales & service page covers the broader scope of what we handle.

Common Unilock Construction Problems We Solve in Upland

• Heaved and shifted pavers on driveways and patios. This is the big one in Upland. Expansive clay swells when wet and shrinks when dry, and a base set too thin can’t absorb that movement. We see it constantly on fill lots where the original grading wasn’t done for paver loads.
• Efflorescence and joint-sand loss on Brussels Block and Beacon Hill. Upland’s hot, dry summers followed by winter rain pull moisture through the pavers and leave white mineral deposits on the surface. The joint sand washes out on sloped lots that drain toward the house. We address both the drainage slope and the sand type.
• Leaning U-Cara retaining walls. When the geogrid is undersized or the slope wasn’t stepped for the foothill grade, wall blocks settle and lean over time. We rebuild these walls with proper grid depth, drainage rock behind the wall, and a base cut into the slope rather than perched on top of it.
• Settlement at driveway aprons. Old citrus-grove root cavities and abandoned irrigation lines run under many Upland driveways. When the base was poured over those voids and the roots decay, the apron settles and ruts. We excavate down, remove the remnants, and re-compact before any new base goes in.
• Edge restraint failure on patios and walkways. Upland’s freeze-thaw cycle isn’t severe, but the Santa Ana winds and dry summers cause soil to shrink away from edge restraints. Once the edge opens up, pavers spread and the whole surface loosens. We install deeper edge restraint and compact the base wider than the finished surface.

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

Upland sits on an alluvial fan at the base of the San Gabriel Mountains, and the soil here is expansive clay that shifts with every wet-dry cycle. Walk a neighborhood off Euclid Avenue or around downtown and you’ll see paver driveways that looked flat five years ago now rippling at the edges. That’s not a paver problem. That’s a base problem. Base prep, not the paver, decides whether your driveway or patio survives in Upland. On former citrus parcels, we routinely hit old grove-root voids and abandoned irrigation lines when we excavate, and those have to be dug out and re-compacted before any Unilock base goes down. If you skip that step, you’re building on a hollow. The paver will find it eventually. This is also why we always check the slope and drainage on every Upland job, because runoff toward the house on those sloped foothill lots in 91784 will push water under the pavers and undo even the best base.

Unilock Models & Products We Service in Upland

We install and repair the full Unilock line we recommend for Upland conditions: Brussels Block for driveways and patios that need a classic, durable surface, Beacon Hill for a more textured flagstone look that hides joint-sand shift better, Bristol Valley for tighter fits and smaller surface work, and the U-Cara retaining wall system for sloped lots where the wall needs to hold back real grade. We use genuine Unilock units and matching OEM caps and alignment systems, because mixing aftermarket caps with new blocks gives you a wall that looks right for two weeks and wrong for ten years. Where existing pavers are sound, we reset and re-sand rather than sell you a full tear-out. Where the base failed, we correct the base. You’ll know the difference in the estimate.

FAQs – Unilock Construction in Upland

Can Unilock pavers be installed over the expansive clay soils common in Upland?
Yes, but only with proper base construction. We excavate deep enough to remove the active clay layer, then install geotextile fabric, compacted aggregate base, and proper edge restraint so the pavers float on a stable platform that doesn’t shift with the clay beneath. Skip that excavation and you’ll get heaving. Call (866) 623-7205 and we’ll walk your lot and tell you what your specific soil needs.

Why is my Unilock patio turning white with efflorescence?
That white mineral deposit is moisture moving through the paver and carrying salts to the surface, which Upland’s hot, dry summers and winter rains accelerate. It’s cosmetic, not structural, but it signals a drainage issue. If water is running underneath the pavers, the base is slowly washing out. We can fix the slope, replace the joint sand with a polymer product, and clean the surface so it stays clean. Give us a call at (866) 623-7205 and we’ll take a look.

My U-Cara retaining wall is leaning toward the Foothill Boulevard side of the yard – what went wrong?
That’s almost always a geogrid problem. The grid was either undersized, installed too short, or not stepped properly for the slope. Sitting on Upland’s clay makes it worse because the ground behind the wall swells and pushes. We rebuild these walls with proper grid depth and drainage rock, and we cut the base into the hill rather than resting it on top. Call (866) 623-7205 for a wall assessment.

Do older Upland lots need special base prep before a paver driveway?
Yes, especially former citrus parcels. Old grove roots and abandoned irrigation lines leave voids under the surface that collapse over time and cause settlement. We excavate those areas, remove the organic material, and re-compact with proper aggregate before the Unilock base goes down. If your lot had citrus or any irrigation remnants, we’ll factor that into the estimate. Call (866) 623-7205 to schedule a site visit.

Can you match new Unilock pavers to my existing Brussels Block or Beacon Hill sidewalk?
We can. We source matching Unilock units from local distributors, and we check the color lot before installation so the new section blends with what’s already there. If your existing pavers are sound, we can reset and re-sand the whole surface so it looks uniform. Call (866) 623-7205 and we’ll bring samples out to match against what you have.
