Unilock Construction in San Martin, CA | Millwright Builders
We install and repair Unilock pavers, walls, and fire features throughout San Martin as a San Martin General Contractor. The difference here is drainage and subgrade: San Martin lots sit on native clay, run on private wells and septic, and answer to Santa Clara County rather than a city planning desk. That changes how a paver base gets built. Call (866) 925-0334 for a free estimate from a crew that has set Unilock on rural Llagas Valley ground before.
Why San Martin Residents Choose Us for Unilock Service
Our crew has spent enough seasons in San Martin to know what the valley floor does to hardscape. Noel Castañeda, who runs Millwright Builders, trained at Skyline College and spent two decades on Peninsula residential work before building the company. When he walks a paver job on a San Martin ranchette, he’s looking at grade, drainage, and what winter runoff will try to do to the edges. We specify the brand, explain the trade-off, and stand behind the install.
We’re an independent Unilock service provider, not a manufacturer affiliate. That means two things: we have no incentive to sell you a full replacement when a re-lay of your existing Brussels Block over a corrected base is the honest fix, and we match Unilock’s own edge restraints and polymeric sands where the product line calls for them while choosing quality aftermarket drainage components where they outperform hidden OEM-only options. Our Unilock sales & service work follows the same standard whether we’re in the county or the city.

Common Unilock Construction Problems We Solve in San Martin
- Joint sand washout on Brussels Block driveways. Winter sheet flow crosses unpaved shoulders onto paver aprons at rural San Martin properties near the Llagas Valley floor, washing polymeric sand from the joints until the blocks start to shift. We re-clean, re-sand with Unilock’s polymeric product, and repair the drainage that caused the washout in the first place.
- Settlement and lippage over native clay. San Martin lots carry expansive adobe clay. A paver patio set on sand without a compacted Class II base will heave and sag after the first wet season. We tear out, grade, compact, and re-lay the same pavers instead of selling you a new surface.
- Efflorescence on Beacon Hill Flagstone and Lineo wall faces. The cool, wet winter and spring pull salts through new pavers, leaving white bloom on the surface. We treat it properly and, more importantly, correct the moisture path behind it so it doesn’t come back every March.
- Edge restraint failure and lateral creep. Where sand-set pavers meet turf or grave, delivery trucks and horse trailers tracking past the apron push edges outward. We reset Unilock edge restraints and rebuild the confinement so the surface stays put.
- Drainage conflicts with septic systems. A paver driveway or patio built near a leach field without subgrade planning can direct runoff into the absorption area. We keep water moving away from the field and toward county-appropriate discharge points.
Unilock Service in San Martin: What Local Conditions Mean for Your Pavers
Because San Martin is unincorporated and many lots run on private wells and septic, a paver driveway or patio built near a leach field has to keep its subgrade and drainage away from the septic absorption area. This isn’t a detail that comes up in Morgan Hill or Gilroy. If the subgrade under a Brussels Block driveway channels runoff toward the leach field, the county can flag it during a permitted addition or ADU septic capacity review. The fix isn’t a thicker paver. It’s a graded base with a channel drain routed away from the absorption area before the first paver gets set.
That’s the part of Unilock work in San Martin that doesn’t show up on a showroom spec sheet. The spec sheet assumes a flat suburban lot with municipal storm drains. Around here, the grade, the clay, and the septic setback all shape the base design. Build it right the first time – the Santa Clara Valley weather will find out if you didn’t.
Unilock Models & Products We Service in San Martin
We work across the core Unilock lines: Brussels Block driveways and patios, Beacon Hill Flagstone surfaces, Estate Wall and Lineo Stone retaining walls, and Unilock fire features. For repairs, we stock Unilock’s matching edge restraints and polymeric joint sands locally so a San Martin job doesn’t wait on a freight shipment. Where a base has failed under an existing surface, re-laying those already-paid-for pavers over a corrected base is often the right call instead of a full replacement.

FAQs – Unilock Construction in San Martin
Yes. Unilock’s high-density pavers handle the valley heat and periodic frost better than poured concrete in most San Martin applications because the joint system flexes instead of cracking. The key is the base and drainage design underneath, which has to account for local clay expansion and winter runoff. Call (866) 925-0334 and we’ll assess your lot for free.
No. We’re an independent hardscape contractor serving San Martin and the wider San Martin service area. That independence means we can recommend the repair that fits your site, including re-laying existing pavers over a corrected base, rather than pushing a replacement.
We use Unilock’s own matching edge restraints and polymeric joint sands where the product line calls for them. For drainage components like channel drains and catch basins, we choose quality aftermarket products that outperform hidden OEM-only options.
Most joint re-sanding and edge restraint repairs finish in one day. A full base correction under a Brussels Block patio takes two to four days depending on size and access. We give a written timeline with the estimate.
