Unilock Construction in Daly City, CA

Unilock Construction in Daly City, CA | Framework Contractors

We provide independent Unilock construction service across Daly City – installing, repairing, and rebuilding segmental paver patios, driveways, and retaining-wall systems – and we also handle Unilock in Colma. The thing that sets our Unilock work apart here is that we build for the fog first: base prep on a Daly City hillside starts with a moisture check on the subgrade, not just a plate compactor. We’re a licensed general contractor based in Orange County, and we know these paver lines well enough to tell you which units belong on a slope and which ones don’t.

Why Daly City Residents Choose Us for Unilock Service

Noel Carbajal, our owner, started on stucco patches and porch reroofs before he was old enough to drive. He’s spent the better part of three decades building and remodeling, and he runs every project the same way: build it right the first time – the second time costs twice as much and nobody’s happy. His crew has laid Unilock pavers on enough graded hillside lots to understand what Daly City’s marine layer does to a paver field over a winter.

We’re not a manufacturer-authorized dealer, and we won’t pretend otherwise. What we are is an independent contractor who installs genuine Unilock products and buys them through established supply channels. That independence means our recommendations are driven by what the site actually needs. For Unilock sales & service across our territory, homeowners can stop by or call, and we’ll walk them through product selection, drainage requirements, and what a realistic budget looks like.

Working with us means one point of contact. Noel is the person who answers your questions about subgrade, geogrid, and joint sand – not a rotating service tech who’s never seen your property. He and our crews have handled enough hillside failures to know that the problem is rarely the paver. The problem is almost always what’s underneath it.

Common Unilock Construction Problems We Solve in Daly City

These are the failure modes we see most often on Daly City properties, and each one has a local cause:

• Base failure on steep graded lots. On the west-side streets, hillside driveways and patios settle and rut when the base wasn’t benched into the slope and tied into drainage. Flat compaction on fill won’t hold. We dig out, re-bench, and rebuild the base so water moves through and away, not under.
• Fog-driven efflorescence and white staining. The persistent marine layer keeps paver joints wet for weeks at a stretch. When polymeric sand wasn’t installed to spec, it mildews and hairline cracks show white bloom that won’t brush out. We remove the failed sand, clean the joints, and re-install correctly so the field stays clean.
• Retaining wall units bulging or leaning. Where original hillside walls were rebuilt without geogrid and free-draining backfill, the wall starts to lean within a few seasons. It’s common on the garage-under lots on the west side, where the old wall has already rotted. We rebuild these in Uni Stone wall units with grid and drainage behind them.
• Paver edge restraint loosening at driveway aprons. Where the grade breaks and the restraint fails, the whole paver field creeps downhill a few inches each season. We reset the apron courses, install proper edge restraint, and tie the base into the slope so the field stays where it belongs.
• Permeable pavers clogged with fog-belt silt. Unilock’s Eco-Priora system works well in Daly City when it’s maintained, but the fog and coastal runoff carry fine silt into the joints. We clean and recondition permeable surfaces rather than replacing them, which saves thousands against pulling up a field that’s still structurally sound.

Unilock Service in Daly City: What Local Conditions Mean for Your Equipment

Here’s the fact that matters more than any product brochure: Daly City’s fog belt cuts the drying window for base prep so sharply that on west-side hillside lots, we often run a moisture test on the subgrade before laying any base. A graded lot that reads dry at 6 inches on a Tuesday can be saturated by Thursday’s fog. Compacting over that wet subgrade is what makes a paver field fail in its first winter.

The marine layer doesn’t just dampen the ground – it changes the whole construction sequence. You can’t lay clean base over saturated soil and expect it to hold. You have to account for drainage before you ever set a paver. That’s why our Daly City bids almost always include a drain rock layer and a geotextile that a dry-climate bid would skip. It’s not an upsell. It’s what keeps the Daly City service area jobs from failing before the fog clears for summer.

On a hillside lot off the west-side streets near Westlake, we pulled out a rotting timber retaining wall holding up a garage-under driveway and rebuilt it in Uni Stone wall units with geogrid and a drain board against the damp hillside. The existing Brussels Block driveway was still solid, so we lifted the apron courses, re-benched the base into the slope, and reset the same pavers with new edge restraint instead of selling a whole new field. The homeowner got a wall that drains and a driveway that stops creeping downhill, for well under replacement cost.

Unilock Models & Products We Service in Daly City

We work with nearly the full Unilock residential lineup, but the lines we see most often in Daly City are Brussels Block (both Brussels Dimensional and the fullnose edging), Uni Stone and Uni-Decor wall units, Beacon Hill Flagstone in the smooth slab format, and the Eco-Priora permeable system for wet-lot drainage. Each one behaves differently on a slope, in the fog, and against a damp foundation.

For anything structural or visible, we buy genuine Unilock units and matching edge restraints. Mismatched thickness and old dye lots read badly next to existing courses – there’s no shortcut that survives a close look. For the drainage layer underneath, we use quality geotextile, clean drain rock, and spec polymeric sand rather than the cheapest bag on the shelf. Our honest position: a settled but sound field gets lifted, re-based, and reset. Pavers almost never wear out. A wall that’s already leaning gets rebuilt with new grid, not patched.

FAQs – Unilock Construction in Daly City

Can Unilock pavers be installed on the steep graded lots common on Daly City’s west side?

Yes, but only with the right base. We bench the base into the slope, tie it into drainage, and use geogrid where the grade exceeds what a flat installation would require. Skip that and the field will creep downhill. Call (844) 681-3590 for an exact quote on your lot.

Why do my Unilock pavers look white and stained after the foggy months?

That’s efflorescence – mineral salts wicking through the paver surface from prolonged joint moisture. The fog keeps joints wet, and when the water evaporates, the white bloom stays. We remove the failed joint sand, clean the surface, and re-install polymeric sand to spec so it stops recurring. If your pavers look white right now, call (844) 681-3590 and we’ll tell you if it’s fixable or if the joints need full replacement.

How do I know if my Daly City hillside retaining wall needs rebuilding or just repointing?

Look at whether the wall is leaning, bowing, or has horizontal cracks. If it’s just cosmetic mortar cracks with no movement, repointing may be enough. If the wall has moved even a few inches, the structural backfill has likely failed and a rebuild with geogrid is the only honest fix. Call (844) 681-3590 and we’ll come look at it.

Do I have to replace every paver if one section of my Unilock driveway has settled?

No. In most cases we lift the settled section, re-base it properly, and reset the same pavers with new edge restraint. The pavers themselves are almost never the problem – the base underneath is. We’ll tell you what’s reuseable and what isn’t, and the quote will reflect that instead of pushing a full replacement.

Can Unilock permeable pavers help with drainage on a Daly City lot that stays wet?

Yes. The Eco-Priora system is designed to move water through the joints and into a drainage layer below, which is exactly what a fog-belt lot needs. The catch is maintenance – fog and coastal silt will clog the joints over time, so the surface needs periodic cleaning to keep performing. Call (844) 681-3590 for a site assessment and we’ll tell you if permeable is the right call for your lot.
