Unilock Construction in Highland, CA | San Mateo Construction
We install, repair, and rebuild Unilock paver and retaining wall systems across Highland, CA, including one thing that sets our work here apart: hardscape on foothill parcels often has to clear Chapter 7A fire-hardening review at the same permit counter as the roof and siding. If you’re planning a paver driveway, patio, or Pisa2 wall in Highland’s 92346 ZIP, call (855) 901-7266 and we’ll walk the site and tell you exactly what the job needs. San Mateo Construction is an independent Unilock service provider, not a manufacturer-affiliated installer, and we’ve worked with Brussels Block, Beacon Hill Flagstone, Pisa2, and Town Hall across the East San Bernardino Valley for years.
Why Highland Residents Choose Us for Unilock Service
A paver driveway or patio fails from the base up, and on Highland’s soils that base does a lot of moving. We know which Unilock product lines hold up under inland heat, what happens when a base gets laid too thin over expansive clay, and how to repair a Brussels Block course so the new pavers blend with the old instead of standing out like a patch. Noel Carrington, our owner, grew up pouring concrete footings with his father and studied construction technology at Skyline College in San Bruno, and he brings the same eye to every hardscape job. If a Unilock patio is draining toward a garage slab instead of away from it, we say so. Then we fix the grade before we relay a single paver. We’re local to this work, but we’re not an authorized Unilock dealer; we’re a general contractor who uses a lot of Unilock and knows how their systems behave in Highland’s climate.

Common Unilock Construction Problems We Solve in Highland
- Efflorescence blooming on Brussels Block and Beacon Hill Flagstone. Highland’s winter rains wick moisture up through the base, and when it evaporates through the paver face it leaves white mineral residue. We see it most often where grading around older ranch foundations pushes water under the patio instead of away from it.
- Polymeric sand joint failure and paver shifting. Dry Santa Ana winds blast grit into the joints, and the thermal swing between hot inland days and cold foothill nights makes pavers flex. Once the sand degrades, Brussels Block units start drifting, and a few crooked courses lead to edge chipping.
- Base settlement and edge spalling on driveways and patios. Highland’s expansive soils swell and shrink through the year. If the original Class II base was under-compacted, which we find on plenty of post-war tract homes, the pavers sink, edges crack off, and the surface develops a washboard look.
- Color fade and surface scaling on older Unilock pavers. Years of intense UV and dry heat without resealing leave the color chalky and the surface rough. This is common on original mid-century patios where the pavers were installed before sealing was standard practice.
- Pisa2 retaining wall movement on sloped foothill lots. Runoff from winter rains pushes against walls that weren’t backfilled with proper drainage stone behind them. We’ve reset walls on lots where the original installer skipped the drain tile entirely.
Unilock Service in Highland: What Local Conditions Mean for Your Equipment
Highland sits at the base of the San Bernardino Mountains in a high-fire-severity zone, and Chapter 7A doesn’t just govern roofs and siding. Hardscape gets pulled into the review when it touches the building perimeter, because ember-resistant construction treats the first few feet around the structure as part of the ignition zone. On a foothill parcel near the national forest boundary, a paver patio or walkway that abuts the house may need noncombustible edging or wall caps specified in the permit packet. Flatland jobs in San Bernardino rarely hear the words “ember-resistant wall cap” in plan review; in Highland, they’re routine. Fencing gets even more scrutiny; a wooden fence running to a home’s outer wall has to be noncombustible within that perimeter zone, and we’ve had Unilock Pisa2 wall projects re-permitted because the wall cap material was flagged. This is the context a generic Unilock page misses, and it’s why we insist on seeing the parcel before quoting hardscape work in 92346’s foothill neighborhoods.
Unilock Models & Products We Service in Highland
We carry repair stock and order regularly from local suppliers who stock Unilock’s core lines, so Highland turnarounds stay practical. Brussels Block is a tumbled concrete paver with a worn-edge profile; Beacon Hill Flagstone runs larger, flatter, and more rectangular with a flagstone-like surface; Town Hall is the modular permeable slab line for a cleaner, cleaner modern lay; Pisa2 is the retaining wall system where batter and caps are built into the design. For repairs, we match Unilock OEM pavers, edge restraints, and polymeric sand so new units blend with existing courses and color. We don’t cut corners with off-brand lookalike pavers, and we’re clear about when a patch won’t hold: widespread base failure or more than roughly a third of cracked or heaved units usually means a rebuild, not a patch-and-go. Our experience with Unilock sales & service runs broad, and in Highland, that means we stock for the climate, not just the catalog.

What drives the cost on a Highland job: existing base condition, how much excavation and regrading is required, whether we’re pulling a fire-hardening permit alongside the paver work, and whether edge restraints or wall caps land in the Chapter 7A perimeter zone. A typical Brussels Block driveway replacement over failed base runs in the upper part of the driveway range because we’re rebuilding the subgrade, not just relaying pavers. Every estimate is free and includes a written scope with material specifics, not a verbal ballpark. Call (855) 901-7266 for exact numbers on your lot.

FAQs – Unilock Construction in Highland
Does Highland’s Chapter 7A fire zone affect a Unilock paver or wall project?
Yes, it can. Hardscape within the building perimeter often gets pulled into the fire-hardening permit review, and noncombustible edging, wall caps, or fence choices may be required where a paver patio or Pisa2 wall comes near the home’s outer wall. On flatland jobs in San Bernardino, these items don’t come up; in Highland’s foothill neighborhoods, they’re routine. Call (855) 901-7266 if you’re planning hardscape in the 92346 fire-severity zone and we’ll tell you what review looks like.
Why does my Unilock Brussels Block driveway keep shifting after winter rains?
The most common cause we find in Highland is a failed or under-compacted base over expansive soil. Water gets under the pavers, the clay swells and shrinks, and the units drift. Patching joints won’t solve it; the base needs recompaction and usually better drainage. That’s a rebuild, not a repair. We’ll come out and core-check the base before we quote anything.
Can you match new Unilock pavers to an existing patio color?
We match Unilock OEM pavers against the existing course, which includes color, texture, and wear. On older Brussels Block or Beacon Hill Flagstone, sun fade means a factory-fresh paver won’t match an original one perfectly, so we plan for blending and we’re honest about that. With the right lot and UV exposure, it usually settles in over time. Call us for a color-match consult.
Is it worth resealing a Unilock paver patio in Highland’s heat?
In Highland’s UV, yes. Sealing slows color fade and surface scaling, and on newer patios it’s the only maintenance that preserves the original finish. On older pavers that are already chalky, sealing alone won’t restore the color, but it will stop further degradation. Driveway sealing runs $250 to $700 depending on square footage, and we quote it as a maintenance item, not a rebuild add-on.
Do you handle Unilock retaining walls on sloped foothill lots?
We do. Pisa2 walls on sloped Highland lots need proper drainage stone, drain tile, and backfill compaction, and we regularly take them on after the original wall has started leaning or weeping. We’ve rebuilt walls where the drain tile was skipped entirely. If your wall is moving, call (855) 901-7266 and we’ll give you a straight read on whether it’s reset or replace.
