Unilock Construction Service Nationwide

Why Saratoga Homeowners Choose Unilock Construction

We provide independent Unilock construction repair and installation across Saratoga, handling everything from Brussels Block driveway re-sets to Onyx wall rebuilds, and also offer Cupertino Unilock service. Our team is not an authorized Unilock dealer, and we don’t claim to be. What we do offer is hands-on experience with how Unilock concrete products actually behave on Saratoga’s sloped lots, clay-heavy soils, and oak-rooted properties, which is where modular paver systems tend to develop real problems. If you’re looking for a contractor who knows Unilock’s product lines well enough to fix a failing driveway rather than just lay a new one, call us at (877) 358-6557.

Most Saratoga hardscape failures we see have nothing to do with the paver itself. Brussels Block, Beacon Hill, and Rivercrest are well-made concrete units. What fails is what’s under and around them: base compaction, edge restraint, joint sand, and drainage. We fix the system, not just the surface.

Why Trust Viceroy Construction for Your Unilock Construction?

Neil Drummond grew up in the Saratoga foothills, not far from the old orchard land along Cox Avenue, and trained in the building trades program at West Valley College. That background in concrete, framing, and structural work translates directly to how we approach Unilock installation on problematic terrain. A paver driveway on a 6% grade with a protected oak 12 feet away is a structural problem first and a cosmetic one second. We scope it that way.

Our Unilock work is built around what actually holds up here. We match Unilock’s original paver and wall-system units for visible repairs so color, texture, and dimensional tolerances stay consistent. For the hidden layers, we use quality aftermarket base aggregate, edge restraint, and polymeric joint sand where those products outperform the original spec. That’s not a corner cut. It’s the difference between a patio that holds its joints through three wet seasons and one that needs re-sanding every spring. The details you don’t see are the ones that matter most.

We’re a full-scope general contractor, which means the same team that handles your Unilock driveway can also manage your kitchen remodel, roof replacement, or ADU addition. One contract, one point of contact, no finger-pointing between subs.

Common Unilock Construction Problems We Fix in Saratoga

• Joint sand washout and paver migration on sloped driveways. After heavy winter rain, water sheets down Saratoga driveways and strips the joint sand straight out. Without sand locking the units, Brussels Block and Cambridge-style pavers begin to drift, especially near the apron and the curb cut. The fix is proper edge restraint, re-compaction, and a high-performance polymeric sand, not just sweeping more sand into the gaps.
• Efflorescence and salt bloom on paver faces. We see a lot of white, powdery patches on Brussels Block and Beacon Hill surfaces in Saratoga. This happens when moisture moves through the paver and evaporates, leaving mineral salts on the face. If the base beneath is trapping water, the bloom keeps coming back no matter how many times you rinse it. The long-term fix is addressing what’s under the paver, not scrubbing the surface.
• Polymeric sand failure at the edge-restraint line. On curves and borders, the joint sand breaks down first. Once the edge restraint fails or wasn’t installed with enough depth, the field spreads and the perimeter gaps open up. We see this constantly on Unilock patios with curved borders in Saratoga backyards. The repair involves pulling the border course, installing proper restraint, and re-sanding the perimeter joints.
• Frost heave and settling on clay-heavy soils. Saratoga’s clay soil expands and contracts with moisture, and when a Unilock patio is laid over an under-compacted base, the surface starts to shift within a season or two. Sections settle, the pattern breaks, and trip hazards appear. The repair is rarely a patch job; the affected area needs to come up, the base re-excavated and mechanically compacted, and the pavers re-laid.
• Tree-root pressure under Unilock patios and walkways. Oak and redwood roots spread wide and shallow in Saratoga. When a patio sits near a protected tree, roots push upward and lift paver sections over time. We work within arborist requirements and root-zone limits, often using deeper base excavation and root barriers where the city allows them.

Unilock Parts & Our Repair-vs-Replace Approach

For visible repairs, we source Unilock’s own paver and wall-system pieces so the replacement matches the existing field in color, texture, and dimension. Unilock’s modular lines have specific manufacturing tolerances, and using a different manufacturer’s paver next to a Brussels Block driveway looks wrong even from the street. For base aggregate, edge restraint, and polymeric joint sand, we use quality aftermarket products that meet or exceed the original spec, because that’s where the performance actually comes from.

Honest repair-vs-replace call: if a failure is confined to joint sand, edge restraint, or a settled base, we re-set and re-sand the affected area. If more than about a fifth of the field is cracked, spalled, or heaved, we recommend a full re-lay rather than chasing individual pavers. Patching a field that’s failing across 30% of its surface just means paying twice. Call (877) 358-6557 and we’ll walk the site and tell you which path makes sense.

Our Unilock Service Process – Step by Step

1. 1
   Site walk and diagnosis. We inspect the full field, not just the visible problem. That means checking edge restraint depth, probing the base, testing drainage, and marking settled sections. On Saratoga hillside properties, we also note slope angle and runoff paths.
2. 2
   Targeted removal and base correction. We pull the affected pavers or wall units, mark them for re-use where possible, and re-excavate the base to proper depth. Compaction is done in lifts, not all at once, because that’s what prevents future settlement.
3. 3
   Re-lay or full install. Unilock’s modular units go back in with consistent joint spacing, proper edge restraint, and pattern alignment. For new installations, we match the manufacturer’s laying pattern and account for slope drainage.
4. 4
   Joint sand and compaction. We sweep high-performance polymeric sand into the joints, water it according to spec, and run a plate compactor over the surface where appropriate. The sand activates and locks within 24 to 48 hours.
5. 5
   Final walkthrough. Neil walks the finished job himself. We check joint tightness, edge restraint, drainage flow, and surface level before we call it done. Workmanship is covered under our warranty, and we stand behind the re-lay.

Unilock Products We Service & Install in Saratoga

We work with Unilock’s core product families: Brussels Block, the tumbled paver with the dimensional variation that makes replacement matching critical; Beacon Hill, the flagstone-style slab that shows efflorescence more readily on shaded lots; and the Onyx and Rivercrest wall systems for retaining walls and seat walls on sloped Saratoga properties. We also handle Cambridge-style cobble and plank profiles for driveways, walkways, and patios. We do not stock Unilock units in a warehouse; we source them per job from local distributors so the batch matches your existing installation as closely as possible.

We Also Service These Brands

Viceroy Construction is not tied to a single manufacturer. Beyond Unilock, we install and service hardscape products from Belgard and Techo-Bloc, and our general contracting work spans KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Kohler plumbing fixtures. If your project goes beyond the driveway, we can handle the whole scope under one contract.
