Unilock Construction in San Martin, CA | San Mateo Construction
We provide independent Unilock installation, repair, and re-leveling across San Martin, and the thing that sets our work here apart is simple: we build around Santa Clara County’s grading rules and the clay-heavy drainage patterns that come off multi-acre ranch parcels, not just the paver pattern. If your driveway apron, shop approach, or retaining wall is shifting after wet-season runoff, that’s a base and drainage problem first, and a paver problem second. Call (855) 901-7266 and we’ll look at the ground before we quote the surface.
Why San Martin Residents Choose Us for Unilock Service
Most San Martin properties aren’t suburban cul-de-sac lots. They’re older ranch homes on acreage, newer custom builds along the Llagas Creek corridor, and Monterey Road parcels with detached shops, barns, and gate aprons that absorb real vehicle loads. We’ve been building hardscape in those conditions long enough to know that a Brussels Block driveway has to be graded and compacted differently here than it would be with a Morgan Hill Unilock service. Our crew sizes the base for Santa Clara County rainfall patterns and the turning radius of a loaded truck, not just foot traffic.
Noel Carrington, who owns San Mateo Construction, has spent the better part of three decades on residential and light commercial jobs across San Mateo County before bringing that frame of mind to south-county ranch work. His approach carries over: figure out what the ground will actually do, then build for that. We’re an independent contractor. We don’t have a dealer agreement with Unilock, and we don’t need one. We specify their pavers and walls because they hold up on expansive clay when the base and drainage are right. See our broader Unilock sales & service scope for more on how we work with the full product line.

Common Unilock Construction Problems We Solve in San Martin
- Paver joint sand washing out and pavers shifting on clay-heavy soils. San Martin’s winter rain runs hard off multi-acre lots, and if the base wasn’t cut to direct water away from the paver field, the joint sand goes first, then the units start walking. We re-cut the base, add proper edge restraint, and re-sand with Unilock’s own joint material.
- Efflorescence and salt bloom on Brussels Block and Beacon Hill pavers. White chalky residue shows up where a slab holds water against a barn or shop wall. It’s a drainage symptom as much as a paver symptom. We fix the water path, clean the units, and only then address whether individual pavers need replacement.
- Retaining wall and step units settling or bulging at the base. Suburban-standard compaction fails on a graded ranch pad with concentrated roof and driveway flow. We see this constantly on U-Cara and Seneca walls that were installed without enough base depth for the actual runoff volume. Re-leveling starts with re-compaction, not face repairs.
- Faded or chipped edge pavers at ranch-entry gate aprons and shop approaches. Gate aprons off Monterey Road take truck and trailer loads that a walkway never sees. Edge units chip, fade, or crack when they’re not set on a full-depth base with real edge restraint. We match and replace the damaged run, then harden the edge detail.
- Heaving where runoff from a legalized barn drains straight across the driveway. This is the most San Martin-specific failure we deal with. When a previously unpermitted barn gets legalized through the County, the drainage pattern often gets overlooked until the first wet season pushes a seam across the paver field. We fix the grade, not just the seam.
Unilock Service in San Martin: What Local Conditions Mean for Your Equipment
Here’s what most paver pages won’t tell you because they weren’t written for this specific town. San Martin sits almost entirely in unincorporated Santa Clara County. There’s no city building department reviewing your project. That means paver aprons, retaining walls, and drainage work tied to a legalized barn or shop often need to go through the County’s grading and permit process, not a city counter. A contractor working in Morgan Hill or seeking a Gilroy Unilock service files through those city departments. Here, the review looks at your entire parcel’s drainage, not just the paver footprint. If you’re replacing or legalizing an outbuilding and your driveway or apron is part of that scope, the County will want to see grading and drainage plans as part of the package. We’ve pulled permits through that process enough times to know what gets flagged and what goes through clean. If the grading review requires a paver base deeper than a manufacturer’s typical residential spec, that’s exactly what we build. Unilock units themselves don’t fail on their own in San Martin. They fail when the base and drainage under them were designed for a different kind of parcel. That’s the information gap we close.
Unilock Models & Products We Service in San Martin
We work with the full Unilock hardscape line, but the models we spec most often for San Martin ranch properties are Brussels Block, the tumbled paver that holds up well on driveways and gate aprons; Beacon Hill, a flagstone-texture unit we use for patios and walkways where people want a less uniform look; U-Cara Multi-Face, the retaining wall system we use when a wall also needs to read as finished architecture; and Seneca, a wall block suited to lower retaining walls and seating edges. When we repair or extend an existing run, we match the original unit and use Unilock’s joint sand and edge restraint products rather than substituting generic cast concrete. We keep common units and materials on hand for San Martin jobs so a repair or extension doesn’t wait a week for a distributor run. Replacement happens only when the base has failed or the units themselves are spalled or cracked beyond salvage. Otherwise we lift, re-base, and relay.

AfterUnilock Service Pricing in San Martin
What you’ll pay depends on access, existing grade, whether the County requires a grading review, and how much base work the parcel actually needs. A ranch driveway with a steep approach and heavy runoff costs more to base correctly than a flat patio pad, and that’s the number that changes the quote the most. Here are the ranges we work within for San Martin projects:
| Service | Typical Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Concrete Driveway Installation | $4,500 – $12,000 |
| Driveway Replacement | $5,000 – $14,000 |

FAQs – Unilock Construction in San Martin
Often, yes, especially on parcels where the driveway is part of a larger scope involving a legalized structure or significant grading. San Martin falls under unincorporated County jurisdiction, so hardscape that changes drainage or is tied to a barn, shop, or second unit can trigger grading review even if the pavers themselves are technically a surface installation. We’ll check the parcel’s history and current permit status before we advise you one way or the other. Call (855) 901-7266 and we’ll tell you what applies to your specific property.
Because the base underneath them wasn’t built for the water and load that area actually gets. On a ranch parcel, rain runs off rooftops, concrete pads, and graded land in concentrated sheets, and if the edge of a paver field catches that flow, the base erodes from underneath. Add a barn door or shop approach that sees truck and trailer traffic, and the compaction has to be significantly deeper and tighter than a residential walkway. We re-cut, re-compact, add edge restraint, and re-lay the same units when they’re sound. For an exact diagnosis, call (855) 901-7266.
Yes. We match the existing unit by size, color family, and finish, and we use Unilock’s own replacement units rather than generic look-alikes. Tumbled pavers like Brussels Block age in a specific way, so if your existing run has been down for a few years we’ll talk about blending new units with existing ones or adjusting the layout so the transition reads intentional. We keep common San Martin-sized orders moving through our distributor faster than a one-off pickup would.
Yes, when the base is built for it. A paver apron at a ranch gate takes the turning load of trucks, trailers, and occasional heavy equipment, and Monterey Road parcels often have concentrated drainage running toward the entry. A properly compacted, properly edged Brussels Block apron handles that better than asphalt patchwork, but it has to shed water and resist lateral movement. We rebuilt one of these off Monterey Road where an old apron had heaved from legalized-barn runoff, and the fix was re-cutting the base so water moved away from the slab, then tying the apron edge into a U-Cara wall. That’s the right way on this kind of parcel. For your property, call (855) 901-7266 and we’ll figure out what applies to your gate and grading.
We schedule base work and compaction for the dry months because San Martin’s clay-heavy soil doesn’t compact well when it’s saturated, and you can’t get a clean paver set on a muddy subgrade. If your project involves drainage or grading review through the County, wet-season timing can also add weeks to permit turnaround. Plan the project so the base goes in between spring and early fall, and we can often complete the paver installation itself anytime the subgrade is dry. Call (855) 901-7266 and we’ll give you a realistic window for your specific site.
