Unilock Construction in Ontario, CA | San Bruno Construction
We provide Unilock sales & service for paver driveways, patios, and retaining walls across Ontario, CA as an independent contractor. The thing that separates our Unilock work here from anywhere else in the Inland Empire is the ground itself: Ontario’s old citrus-and-dairy parcels and warehouse-district soils need deeper, geotextile-separated bases before a single Brussels Block paver goes down. If you’re planning Unilock work in Ontario, call (866) 472-1908 for a free estimate. We’re not authorized by Unilock, which is exactly why we can tell you what actually holds up.
Why Ontario Residents Choose Us for Unilock Service
We’ve pulled apart failed Unilock installs across Ontario’s mid-century tract neighborhoods and downtown grid, and we know the brand’s tolerances better than most crews who just lay pavers and leave. Base prep is everything. Edge restraint is everything. Joint sand selection is everything. Get one wrong and you’ll watch a Brussels Block driveway creep toward the garage within two winters. Noel Carvalho, owner of San Bruno Construction, grew up watching neighborhoods get built around him off El Camino Real in San Bruno and trained at Skyline College in construction technology, where reading plans and understanding load paths came before anything else. That’s the lens we bring to Unilock work in Ontario: we treat a paver driveway like a structural system, not a cosmetic layer. We stock Unilock’s own OEM edge restraints, joint sand, and wall connectors because off-brand substitutes don’t match the paver dimensions or the wall locking geometry. When we repair, we repair rather than replace when the base is sound. We’re an independent contractor and are not authorized, sponsored, or endorsed by Unilock.

Common Unilock Construction Problems We Solve in Ontario
- Efflorescence bloom on Brussels Block and Beacon Hill pavers. Ontario’s hot inland sun pulls salts to the surface after Santa Ana dry spells followed by winter rain. The white chalky film isn’t usually a bad batch: it’s trapped moisture migrating upward because the base isn’t draining. We fix the drainage, then clean and reseal the surface.
- Joint sand washout and paver migration on driveways over expansive clay. The warehouse districts and old citrus parcels in Ontario sit on soils that pump seasonally: swelling when wet, shrinking when dry. That movement forces pavers apart and washes out polymeric sand. We excavate down past the active zone and rebuild with geotextile and compacted aggregate before re-sanding.
- Edge restraint failure and paver creep on patios and driveways. When a previous installer locked in polymeric sand without a proper geotextile-and-aggregate base, or didn’t allow a genuine dry cure window, the edges fail first. Pavers start drifting. We reset Unilock’s OEM edge restraints and re-sand correctly.
- Alpine Stone and U-Cara wall courses bowing or settling. Ontario’s historical agricultural grading left fill in places that should never carry a leveling pad. Walls on uncompacted fill tilt and bow within a few seasons. We tear down to competent soil, compact an engineered base, and rebuild the wall so the courses actually align.
- Buried oil tanks and old agricultural piping during excavation. Downtown Ontario remodels frequently hit remnants of the city’s citrus and dairy past underground. It stalls the paver layout until the find is cleared. We coordinate the discovery so the project doesn’t spiral.
Unilock Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario’s warehouse-district and former citrus-and-dairy parcels sit on expansive soils and high historic water tables. A Unilock paver driveway or patio here needs a deeper, geotextile-separated aggregate base than the same square footage would in neighboring Rancho Cucamonga, because the subgrade moves more and drains differently. And downtown remodels can hit buried oil tanks or old agricultural piping mid-excavation, which stalls the paver layout until the find is cleared. We’ve handled both. On a mid-century tract house off the downtown grid, our crew pulled up a settled Brussels Block driveway where the pavers had crept toward the garage and the polymeric sand had washed out over two winters. Excavation revealed the original base sitting directly on expansive clay, so we removed it down past the active zone, laid geotextile and a deeper compacted aggregate base, reset the salvaged Brussels Block, and locked it with Unilock edge restraint and fresh joint sand. The driveway has held through two Santa Ana seasons since. Good construction doesn’t announce itself: it just works, year after year.
Unilock Models & Products We Service in Ontario
We work with the Unilock lines most common across Ontario: Brussels Block, the tumbled dimensional paver used for driveways and patios; Beacon Hill, the flagstone-style patio paver that shows efflorescence fastest when drainage is wrong; Alpine Stone, the tumbled retaining-wall block; and U-Cara, the segmental retaining-wall system with its own locking geometry. We use Unilock’s OEM edge restraints, joint sand, and wall connectors because substitutes don’t match the paver’s unit dimensions or the wall system’s geometry. For faster turnaround across Ontario, we keep OEM restraint and sand stock on hand, which means we’re not waiting on a parts order to re-set your driveway. For deep base rebuilds over pumping clay, we quote exactly what the excavation and compaction will take.

FAQs – Unilock Construction in Ontario
Efflorescence and sand loss almost always trace back to drainage. Ontario’s hot sun pulls moisture upward through the pavers, carrying salts that form the white bloom. The fix is correcting the base drainage before cleaning and resealing. Call (866) 472-1908 and we’ll tell you what’s happening under your specific driveway.
Yes, but the base build is different. Those parcels sit on expansive soils with high historic water tables, so we cut out the active clay zone and lay geotextile plus a deeper compacted aggregate base. Skip that step and the driveway pumps apart within a few seasons. Call (866) 472-1908 for an estimate that includes the excavation work Ontario’s soils actually require.
For most residential paver patios at grade, no. For driveway replacements that alter drainage patterns or for any retaining wall over three feet, yes. Ontario’s code enforcement is strict about redevelopment goals, so we check before we cut. Call (866) 472-1908 and we’ll tell you what your specific address triggers.
They accelerate wear, but they don’t wreck properly installed pavers. The real damage in Ontario comes from what the hot-dry-then-wet cycle does to the soil underneath. Santa Ana winds also kick dust and grit onto sealed surfaces, which means cleaning and resealing more often. Call (866) 472-1908 for a maintenance schedule specific to your patio or driveway.
It settles if the leveling pad sits on fill left over from Ontario’s agricultural days. We compact an engineered base down to competent soil before the first Alpine Stone or U-Cara course goes down, which is the difference between a wall that bows in two years and one that holds for decades. Call (866) 472-1908 for a free estimate on your wall.
