Unilock Construction in San Martin, CA | San Bernardino Contractors
Unilock paver work in San Martin runs on a different approval chain than it does five minutes up the road in Morgan Hill or Gilroy. We’re San Bernardino Contractors, and we install and repair Unilock pavers, driveways, patios, and retaining walls across this unincorporated stretch of Santa Clara County where county building review and well/septic verification often shape how a project gets sequenced. That means the base prep we do on a Brussels Block driveway off Llagas Road has to account for setback rules and drainage patterns that a city inspector would never flag. Call (855) 473-5620 and we’ll walk your specific parcel through what actually applies.
Why San Martin Residents Choose Us for Unilock Service
We’ve worked Unilock product lines long enough to know which pavers hold up under San Martin’s hot dry summers and which ones need a different base spec when winter rain hits the valley clay. Ruben Castillo, our owner, grew up watching his uncle reroof houses and frame garages out in San Bernardino; that’s where he learned to care about load paths and drainage before cosmetics. He carries that same stubbornness into every paver job. We are not authorized or sponsored by Unilock, and we don’t pretend to be. What we are is independent, hands-on familiar with Brussels Block, Beacon Hill, Umbriano, and Elegance, and honest about when a failing patio can be salvaged with re-sanding and re-leveling versus when full replacement is the smarter spend. If it’s not built right the first time, you’re just paying for it twice.

Common Unilock Construction Problems We Solve in San Martin
- Efflorescence on Brussels Block and other concrete pavers. San Martin’s dry summer heat pulls moisture up through the paver, and when winter rain follows, you get that white chalky bloom. It’s usually cosmetic but it tells you base drainage isn’t moving water away fast enough.
- Settling and heaving over clay soils. Large-lot ranch properties around San Martin often got minimal base depth when the original driveways went in. Expansive clay swells in winter and shrinks in summer, and pavers start to dip and shift. We excavate deeper than the original spec and recompact in lifts.
- Joint sand loss and weed intrusion. Umbriano and Beacon Hill installations without proper edge restraint lose polymeric sand after repeated wet-dry cycles. We see this a lot on driveways and patios where the original edge was just a row of pavers meeting lawn or bare dirt.
- Surface spalling and color loss on older Elegance pavers. Elegance is a premium line, but wildfire smoke residue and CalFire defensible-space equipment traffic can etch and dull the surface over time. We assess whether cleaning and sealing recovers the finish or whether your money’s better spent on selective replacement.
- Base washout from winter runoff. Properties on slopes or near drainage channels lose fines from the aggregate base during heavy rain. You’ll see pavers start to rock. We install a geotextile separator on any re-level project where runoff’s been a problem.
Unilock Service in San Martin: What Local Conditions Mean for Your Equipment
Here’s the thing most paver contractors won’t tell you until you’re already deep into a job: because San Martin is unincorporated, a Unilock paver driveway or patio that adds impervious surface or changes grading can trigger Santa Clara County building department review before permits are issued. And on many of these ranch-style lots off Llagas Road and throughout 95046, that review includes verification of private well and septic setbacks. We did a project where the homeowner wanted to expand their driveway pad; the county made us shift the design eight feet to keep runoff off the leach field. A job in Morgan Hill or Gilroy would have gone through a city building department and likely never touched a septic file. That approval chain changes sequencing. It can add a couple weeks before excavation starts. We factor it in from day one so your permit doesn’t become a surprise.

FAQs – Unilock Construction in San Martin
Yes, in many cases. Because San Martin is unincorporated, projects that add impervious surface, alter drainage, or require grading go through Santa Clara County building review, not a city building department. On rural residential and ranch parcels, that review often includes well and septic setback verification before permits are issued. Call (855) 473-5620 and we’ll figure out what your specific parcel triggers.
Expansive clay swells with winter moisture and shrinks through summer, which means a thin base guarantees settling. We excavate deeper than the typical 4-to-6-inch minimum, install a geotextile separator, and compact aggregate in lifts to create a stable platform that resists heaving. This is the single biggest reason some San Martin driveways fail in five years and others look flat at fifteen.
Yes, and they’re actually a smart choice for it. Unilock pavers are non-combustible, so a paver patio or driveway can serve as a defensible-space feature while improving drainage. On our Llagas Road project near Unilock in Corralitos, we replaced a failing concrete driveway with Brussels Block pavers specifically to meet defensible-space clearance while directing runoff away from the septic leach field. You’ll want to confirm your specific zone requirements with the county before finalizing a design.
Efflorescence is mineral salts carried to the paver surface by moisture. San Martin’s pattern of hot dry summers followed by winter rain makes it common on Brussels Block and other concrete pavers, especially where base drainage is weak. It’s usually cosmetic and can be cleaned, but if it keeps returning, the issue is water moving up through the base. Call (855) 473-5620 for a frank assessment; estimates are free.
Unilock paver driveways in San Martin typically run $7,000 to $18,000, while a comparable concrete driveway runs $4,500 to $12,000. Pavers cost more up front, but they handle clay-soil movement better than a monolithic slab and can be re-leveled section by section if shifting occurs. Over the life of a ranch property, pavers usually cost less per year. We’ll quote both and let you decide.
