Unilock Construction in San Carlos, CA | Daly City Construction
We provide independent Unilock installation, repair, and rebuild service across San Carlos, and the one thing that sets our work here apart is that we build for the hills. Unilock sales & service is most of what we do with hardscaping, but San Carlos demands more than paver knowledge: it demands knowing what happens when expansive clay meets a driveway at 15 percent grade, and that’s where we earn our keep. If you’re planning a Unilock paver driveway, patio, or retaining wall, call (866) 505-5254 for a free estimate.
Why San Carlos Residents Choose Us for Unilock Service
We’ve installed and repaired Unilock pavers and walls on San Carlos hillsides long enough to know the product line the way a mechanic knows a specific engine family. Noel Cabrera, our owner, grew up in Daly City’s Westlake district, where postwar tract homes taught him early what poor drainage does to a foundation. That background, plus his training in construction technology at City College of San Francisco, means he’s the person who walks your job, looks at the slope, and tells you what the house needs, not what you think it needs.
We’re independent. Unilock doesn’t authorize or badge us. Our credibility comes from tearing out failed systems and rebuilding them correctly, which is the only credential that means anything when a segmental wall starts to lean after one wet winter.
We use Unilock OEM pavers, wall blocks, and joint sand for replacements so color and dimension match the existing install. For base aggregates and geotextiles, we source aftermarket materials that meet or exceed local engineering specs. That combination gives you factory-correct surfaces on a foundation built for San Carlos soil.

Common Unilock Construction Problems We Solve in San Carlos
- Brussels Block settlement on sloped driveways. Driveways above Laurel Street negotiate grades that put enormous stress on paver bases. When the original install skips proper compaction for expansive clay, pavers develop lippage, the joint sand falls through, and the surface starts shifting under tire load.
- Beacon Hill efflorescence and surface spalling on hillside patios. San Carlos winter rains push water through joint sand and down to the paver base. On Beacon Hill pavers, that trapped moisture carries salts upward and causes the white chalky staining and surface flaking we see on canyon-facing patios.
- Estate Wall bulging or cracking on canyon lots. Segment retaining walls in San Carlos frequently fail because the original builder didn’t account for hydrostatic pressure. Clay soils hold water, and when drainage is missing or clogged, pressure builds behind the wall until blocks crack and the face begins to rotate.
- Bristol Valley rutting and shifting in driveway aprons near El Camino Real. These lower-lying areas see saturated subgrade during heavy rain, and heavy vehicle loads then work the pavers into the weakened base, creating ruts and surface movement.
- Joint sand loss across all paver surfaces. The marine layer and winter rains conspire to wash fines from paver joints. When joints empty out, individual pavers start working loose and the whole surface loses structural integrity.
Unilock Service in San Carlos: What Local Conditions Mean for Your Install
San Carlos sits where the flat bay plain meets the steep, wooded slopes of the Santa Cruz Mountains. That geography means construction here isn’t flat-lot tract building; it’s hillside engineering with drilled piers, retaining walls, and grading plans. On the hillside streets west of El Camino, contractors routinely deal with grade beams and caisson foundations to reach stable rock, similar to Unilock in Redwood Shores hillside conditions. For Unilock work, the permitting side is what catches people off guard: any addition on a slope typically triggers a geotechnical report, and that report often calls for an engineered retaining wall. Unilock Estate Wall segmental blocks frequently get specified for these grade changes because they’re flexible, permeable, and can be engineered to hold a cut slope. But the engineering report also means the wall base preparation must be deeper and the drainage more deliberate than anything on a flat Peninsula lot. We pull the geotech, read the recommendations, and build to them. That’s the difference between a wall that stands for 30 years and one that bulges after its second rainy season.
Unilock Models & Products We Service in San Carlos
We work with the full Unilock hardscape line that shows up on San Carlos properties. Brussels Block, Beacon Hill, Bristol Valley, and Estate Wall are the four we see and service most often, plus Belmont Unilock service when needed. Brussels Block gives you that tumbled, timeworn look that reads well on older San Carlos bungalows along El Camino and Laurel Street. Beacon Hill, with its flagged rectangular shape, suits patios and walkways where a cleaner line is wanted. Bristol Valley offers a premium driveway surface. Estate Wall is the workhorse for segmental retaining walls on sloped lots. For repair work, we stock the common OEM replacement pavers and wall blocks locally for fast San Carlos turnaround. When we need color lots matched, we order direct from Unilock distribution, but we always start with what’s already on site.

AfterUnilock Service Pricing in San Carlos
What you’ll pay depends on what’s under the pavers. A fresh paver driveway on a flat apron is straightforward. A steep driveway above Laurel Street that needs geogrid reinforcement, channel drains, and deeper base prep costs more because it’s a different scope of work. Here are the ranges we work within for San Carlos jobs:
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
Every estimate includes an on-site evaluation of base condition, drainage, and access. We give you a written line-item quote so you know what’s being built and what it costs. Call (866) 505-5254 to schedule your free estimate.

FAQs – Unilock Construction in San Carlos
If the wall is part of an addition or any permitted construction on a slope west of El Camino, San Carlos building department will likely require a geotechnical report. The report determines the wall’s design parameters, drainage requirements, and base depth. We coordinate with the geotechnical engineer and build the wall to the stamped plan. If you’re unsure whether your project needs one, call (866) 505-5254 and we’ll tell you straight.
The marine layer keeps moisture moving through paver surfaces for much of the year, especially on hillside patios that get morning fog. Constant moisture accelerates efflorescence on pavers like Beacon Hill and weakens joint sand over time. Proper base drainage and sealed joints reduce the problem significantly, and that’s what we build for on every San Carlos install.
Sometimes, and sometimes it’s a bad idea. On a flat, structurally sound slab, an overlay can work. On a hillside driveway where the concrete has already cracked from clay movement, installing pavers over it just transfers the movement problem to the pavers. We assess the slab first and tell you honestly whether an overlay will last or whether the concrete needs to come out. The assessment is free; call (866) 505-5254.
Brussels Block is what we install most often on steep San Carlos driveways, but the paver choice matters less than the base beneath it. A geogrid-reinforced base with a channel drain is what keeps pavers locked on a 15 percent grade. We use Unilock OEM pavers with an engineered base so the surface stays stable through wet winters. If your current driveway is shifting, call (866) 505-5254 and we’ll tell you whether repair is enough or a rebuild makes more sense.
With a properly engineered base and maintained joint sand, a Unilock driveway in San Carlos should give you 20 to 30 years of service. Driveways that fail early almost always fail because the base was underbuilt for the slope and soil, not because the pavers wore out. That’s why we focus on what’s underneath. Call (866) 505-5254 for a free estimate and we’ll inspect what’s happening below the surface.
