Unilock Construction in Elkhorn, CA | Daly City Construction
We’re Daly City Construction, and we install and repair Unilock pavers, walls, and driveways across Elkhorn, CA (95039) — unlike any Elkhorn General Contractor, we specialize in Unilock systems built for this soil. The honest truth about Unilock work here: Elkhorn’s high groundwater and saturated clay soils mean base preparation matters more than the paver itself. We’re an independent contractor, not Unilock-authorized, and we’ve spent years figuring out what actually holds up in this marine-influenced ground. Call (866) 505-5254 for a free estimate on paver driveways, patios, or replacements in Elkhorn.

We’re a full-scope general contractor with access to 50+ manufacturer brands, so Unilock is one strong option in a broader hardscaping conversation, not our only product. That matters when you’re weighing Unilock against other systems for your specific Elkhorn site. Unilock sales & service is something we handle end to end, from material selection through final compaction.
Why Elkhorn Residents Choose Us for Unilock Service
Noel Cabrera, our owner, grew up in Daly City’s Westlake district, where he spent summers watching his uncle re-frame a garage and learned early that real construction work is about what’s underneath the surface. That instinct carries directly into Elkhorn, where what’s underneath is usually saturated clay and groundwater that doesn’t drain. We don’t just lay pavers; we build bases that can handle what Elkhorn’s soil does to them.
We also respect the regulatory reality here. Elkhorn sits adjacent to the Elkhorn Slough National Estuarine Research Reserve, and that changes how drainage, runoff, and siting get reviewed. A contractor who doesn’t know that will scope your project wrong from day one. We do know it, and we plan for it from the first site visit. Elkhorn service area work is a regular part of our week, not an occasional trip.
When we quote an Elkhorn Unilock project, we’re quoting it with local soil, local drainage rules, and local weather in mind. Not a generic template. Tell me what the house needs, not what you think it needs – then we’ll figure out the right fix. That’s how Noel puts it, and it’s how our crew works.

Common Unilock Construction Problems We Solve in Elkhorn
- Paver settling and heaving from saturated clay subsoil. Elkhorn’s high groundwater table keeps clay soils wet year-round, and a base that wasn’t built with drainage in mind will fail within a couple of wet seasons. We pull the section, dig deeper, install aggregate and drainage mat, and re-set the pavers so they stay put.
- Efflorescence and surface staining from coastal moisture. The salt-laden fog off Monterey Bay leaves a white, chalky film on Unilock pavers that homeowners often mistake for product failure. It’s not a defect; it’s the marine air. We clean and seal to control it, and we can recommend sealers that hold up better in this specific environment.
- Joint sand erosion and weed growth from winter rains. When surface drainage doesn’t move water away from slough-side grade, the polymeric sand between Unilock joints washes out, then the weeds move in. We re-grade where needed, re-sand, and adjust drainage so the fix lasts more than one winter.
- Differential movement in Unilock retaining walls. Frost heave is rare in Elkhorn’s microclimates, but it does happen in spots, and expansive clay causes more problems year-round. Walls without proper engineered footings and drainage stone behind them start to lean or crack. We rebuild the wall section with the right footing and backfill.
- Paver replacement within existing installations. When individual Unilock units crack or stain beyond cleaning, we source matching color kits and replace single pavers or blocks rather than tearing out entire sections. That keeps the visual and structural consistency without a full rebuild cost.
Unilock Service in Elkhorn: What Local Conditions Mean for Your Equipment
Here’s the thing nobody outside this ZIP code fully appreciates: Elkhorn’s location next to the Elkhorn Slough National Estuarine Research Reserve means Unilock installations may require review under the Reserve’s watershed protection guidelines. That often triggers drainage and runoff control measures beyond standard building code. A paver patio that would sail through permitting in, say, Salinas can require a stormwater plan in Elkhorn. That’s not a burden; it’s the reality of building next to a federally protected estuary. And it changes material choices, base depths, and even where on the lot you can place hardscape without triggering extra review.
On a ranch-style property off Dolan Road, we installed a Unilock Brussels Block patio where the existing soil was saturated clay. Our crew excavated and replaced 12 inches of subbase with compacted aggregate and a drainage mat, then set the pavers with polymeric sand. Two wet seasons later, that patio hasn’t heaved or washed out. That’s what Elkhorn-specific base prep looks like in practice. Contractors who build here like they’re building inland get callbacks. We don’t.
Unilock Models & Products We Service in Elkhorn
We install and repair the full Unilock line we’ve worked with most often along the Monterey Bay coast, including Unilock service in Watsonville and nearby communities: Brussels Block, Beacon Hill, Il Campo, and Elegance. Brussels Block is our most common Elkhorn recommendation for driveways and patios because its tumbled edges and varied sizing hide the minor movement that coastal clay inevitably produces. Beacon Hill suits homeowners who want a cleaner, more contemporary line. Il Campo is a larger-format paver that reads well on rural-residential acreage homes, where a bigger visual field fits the scale of the property.
For repairs and expansions, we source genuine Unilock components and matching color kits. That matters more than people think. Aftermarket or mismatched units create visual seams and can have slightly different dimensions, which throws off joint lines. When a section is damaged but the base and drainage are sound, we replace individual pavers or wall blocks rather than pushing a full tear-out. It’s usually faster, cheaper, and structurally identical to the original installation.

What drives cost in Elkhorn specifically is the base work. If your soil is saturated clay with high groundwater, you’ll need deeper excavation, more aggregate, and possibly a drainage mat. That’s not a markup. It’s what keeps your pavers from settling. A free estimate from us includes a site walk, a soil check where feasible, and a written, line-item quote. Call (866) 505-5254 to schedule yours.

FAQs – Unilock Construction in Elkhorn
Elkhorn’s position next to the Elkhorn Slough National Estuarine Research Reserve means many Unilock projects require drainage and runoff review beyond standard building code. The Reserve’s watershed protection guidelines can trigger stormwater control measures that affect base depth, permeable surface choices, and siting. We handle this as part of every Elkhorn estimate. Call (866) 505-5254 and we’ll walk your specific lot before you commit to anything.
Yes, if the base is built for it. Elkhorn’s saturated clay requires deeper excavation, compacted aggregate subbase, and often a drainage mat before pavers go down. Skip those steps and settling is almost guaranteed within two wet seasons. Call (866) 505-5254 for a free estimate and we’ll tell you exactly what your soil needs.
Efflorescence is the white, chalky film that forms when moisture carries salts through the paver and evaporates on the surface. Elkhorn’s salt-laden fog and constant coastal moisture make it common. It’s not a product defect. We clean the surface and apply a breathable sealer suited to marine environments. For an exact quote on cleaning and sealing your Elkhorn pavers, call (866) 505-5254.
Brussels Block has tumbled edges and varied sizing that visually absorb the minor movement coastal clay produces. Beacon Hill is a cleaner, more uniform look, but it shows any base imperfection more clearly. For most Elkhorn driveways, we recommend Brussels Block unless you have a strong design preference for the contemporary line. Call (866) 505-5254 and we’ll bring samples to your property.
Unilock provides a product warranty on manufacturing defects, but installation workmanship and weathering performance are separate matters. Marine-influenced conditions in Elkhorn make base preparation the real warranty, and that’s ours to stand behind. As an independent contractor, we’re not authorized by Unilock, but we source genuine components and back our installation work. Call (866) 505-5254 for a free estimate.
