Unilock Construction in San Martin, CA | Moreno Valley Builders
We install and repair Unilock pavers and walls across San Martin, from paver driveways and patios to retaining walls and walkways. The difference here isn’t the paver line itself, it’s what sits underneath: San Martin’s expansive clay soils move with every wet winter and dry summer, and a Unilock installation is only as good as its base prep. Moreno Valley Builders handles that part with the same attention we give the surface, and we’re one call away at (877) 752-3154.
We’re an independent Unilock installer, plain and simple. No manufacturer affiliation, no corporate program. What we bring is a decade-plus of working with the full Unilock line on San Martin’s rural lots, ranch homes, and newer custom builds, and a general contractor’s understanding of how county permitting and septic clearances shape every project here. For more on our broader material work, see Unilock sales & service.
Why San Martin Residents Choose Us for Unilock Service
Most contractors can lay pavers. Few can tell you why the same Unilock Brussels Block patio that holds up fine with Morgan Hill Unilock service starts shifting three years in on a San Martin parcel with heavy clay. The answer is almost always base failure, not paver failure. We over-excavate, install geotextile, and compact in lifts because we’ve seen what happens when someone skips those steps to save a few hundred dollars.
Noel Trevino grew up in Sunnymead Ranch and has spent close to three decades building and fixing homes across the Inland Empire and the South Bay. He picked up construction technology at Riverside City College, where the framing and concrete coursework gave him a foundation he still leans on. When a project has gone sideways, he’s the contractor people call to get it right the second time. That matters when you’re working with a San Martin General Contractor, where a misread county permit set or an undersized base means redoing work on a job site thirty miles from the nearest supply yard.
One contractor. Every phase. If the details aren’t right on paper, they won’t be right in the wall.

Common Unilock Construction Problems We Solve in San Martin
San Martin’s climate and soil create predictable failure patterns. Here’s what we see most often:
- Settling and heaving in paver driveways and patios. Expansive clay soils shrink during San Martin’s hot, dry summers and swell with winter rain. Without a properly engineered base with geotextile separation, the pavers ride that movement and you get dips, lippage, and cracked edges within a few seasons. This is the single most common call we get.
- Efflorescence on north-facing paver surfaces. White, chalky mineral deposits show up on Unilock pavers because local clay soils and irrigation water carry high alkalinity. North-facing patios and walkways stay damp longer, so the salts migrate to the surface and crystalize. It’s almost always cosmetic, but it looks terrible and generic cleaners make it worse.
- Joint sand erosion from winter frost and heavy rain. San Martin gets real frost in the winter and concentrated rain events. If the polymeric sand wasn’t installed correctly or was allowed to dry out during application, joints erode, pavers loosen, and weeds move in. Re-sanding is straightforward, but only if you address what caused the erosion in the first place.
- Color fading and surface wear from summer UV. Unilock pavers are color-through, but older installations sealed with low-grade products fade and chalk under San Martin’s intense summer sun. We strip old sealers and reapply or recommend leaving the surface natural depending on the paver line and age.
- Edge restraint failure on driveways and patios. Without a solid edge restraint, the perimeter pavers on a Unilock driveway drift outward under vehicle loads, especially on San Martin’s larger parcels where driveways run long and take turning stress.
Unilock Service in San Martin: What Local Conditions Mean for Your Equipment
Here’s the detail generic Unilock pages won’t tell you: San Martin is unincorporated, which means every paver project here pulls permits through Santa Clara County, not a city hall. On a rural parcel, that often triggers a well and septic review before any paver work can begin. A paver driveway replacement that might take four weeks with Gilroy Unilock service can take six to eight in San Martin, purely based on the county’s review backlog and septic clearance requirements.
Take a recent project off Llagas Avenue. A homeowner had an asphalt driveway cracking badly from expansive clay underneath. Before we could do anything, we obtained the Santa Clara County permit and verified septic clearance. Then we excavated 12 inches of clay, laid a geotextile separator, compacted a proper aggregate base, and installed Unilock Brussels Block in a herringbone pattern with polymeric sand. That driveway now handles winter rains and summer heat without shifting. The work itself took a few days. The permitting and clearance added weeks. Knowing that going in is the difference between a smooth project and a stressful one.
This is why homeowners across San Martin service area call us before they get three quotes. We already know what the county will ask for.
Unilock Models & Products We Service in San Martin
We work with the full residential Unilock line, including Brussels Block, Beacon Hill, Brussels Dimensional Stone, and Copthorne. Each has different dimensional tolerances, surface textures, and color blends, and matching a repair to an existing installation requires knowing which plant ran the original lot.
For repairs, we use Unilock OEM pavers to keep color and dimension consistent. Your project, your material choices. But for base materials and joint sand, we specify aftermarket products that meet or exceed Unilock’s specs for San Martin’s expansive clay and freeze-thaw cycles. We don’t stock full pallets of Unilock lines locally, what we do instead is work directly with Unilock’s Northern California distribution to get the right pavers pulled and staged for your project. That keeps turnaround tight without holding inventory that fades in the sun.

The biggest cost driver in San Martin isn’t the pavers, it’s the base. A proper geotextile, aggregate lift, and compaction protocol adds real cost, but skipping it is false economy when the clay underneath moves. A free estimate from us includes a site walk to check access, drainage, and existing base conditions, along with a written line-item quote. Call (877) 752-3154 to schedule yours.

FAQs – Unilock Construction in San Martin
Yes. San Martin is unincorporated Santa Clara County, so paver driveways and patios that change drainage or are tied to new construction require county permits, and rural parcels often need well and septic clearance before approval. We handle the permit package and the county coordination. If you’re replacing an existing driveway in kind, the path is usually simpler, but it still runs through the county. Call (877) 752-3154 and we’ll tell you exactly what your parcel needs before you spend a dollar.
The pavers themselves hold up fine, it’s the base that fails. Unilock’s concrete pavers are strong enough, but if the base under them is too thin or lacks a geotextile separator, San Martin’s shrink-swell clay cycles will move the whole assembly. We over-excavate and install a geotextile and compacted aggregate base that meets Unilock’s spec for poor soils.
That depends on the paver line, color, and how long it’s been in the ground. Old pavers fade even with color-through pigment, so a repair patch may be visible for a season or two until it weathers in. We pull OEM Unilock pavers from the line the original install used, and we’ll show you a sample before we cut anything.
Efflorescence is caused by water and soluble salts in the paver or base migrating to the surface. On San Martin’s north-facing surfaces, you’ll see more of it because the pavers dry slower. Prevention is mostly about drainage and a clean base, and if it appears, we use paver-safe efflorescence cleaners rather than acid washes that damage the surface. We can also re-seal with a product that allows the pavers to breathe.
Most paver driveways and patios take three to five working days on site once the base is prepped. The clock that matters in San Martin is the county permit window, which can add two to four weeks depending on parcel type and whether well and septic review is triggered. We sequence work so the county review happens while we order materials. Call (877) 752-3154 for a timeline based on your specific parcel.
