Unilock Construction in San Martin, CA | San Bruno Construction
We provide independent Unilock paver and retaining wall construction across San Martin, CA – driveways, patios, equestrian paths, and estate walls built for rural Santa Clara Valley properties – and also offer Morgan Hill Unilock service for nearby properties. What sets our work apart here isn’t the paver brand; it’s the excavation and base prep we do first, because San Martin’s horse properties sit on ground that was graded for pasture drainage, not vehicle loads. As an independent contractor, we’re not authorized or sponsored by Unilock, but we install, repair, and replace their systems every week. Call (866) 472-1908 for a free estimate on any Unilock project in San Martin.
Why San Martin Residents Choose Us for Unilock Service
Unilock pavers are a common sight on San Martin ranch entries and around barns, but too many installs fail early because the base underneath wasn’t built for what actually drives over it. Our crew understands the difference between a suburban driveway and a pasture access road – and we plan excavation depth, compaction, and drainage accordingly. Noel Carvalho, owner of San Bruno Construction, grew up in San Bruno and trained in construction technology at Skyline College, where he learned to read grades and think through load paths before a single tool comes off the truck. That training matters when an owner wants a Brussels Block driveway running past a horse barn to a shop on the back parcel. We carry OEM-compatible Unilock edge restraints, polymeric sand, and matching pavers, and we coordinate the entire job – grading, base, drainage, and paver setting – under one contract and one accountable crew. Our Unilock sales & service work across Santa Clara County keeps us sharp on the product line and its failure points.

Common Unilock Construction Problems We Solve in San Martin
- Base failure over expansive Santa Clara Valley clay. San Martin’s soil expands and contracts through wet and dry seasons. Ranch entries that were once ag pads capped with a thin layer of base will heave and settle, leaving pavers rocking under truck tires. We re-excavate to stable subgrade before setting any Unilock field.
- Polymeric joint sand washing out during winter rains. When a driveway drains toward a barn or arena instead of a defined swale, winter storms push water through the joints and strip the sand. Open joints collect weed seed and let individual pavers shift. We re-grade the drainage path before re-sanding.
- Efflorescence and salt bloom on Brussels Block and Beacon Hill faces. San Martin’s hot, dry summers pull mineral salts to the paver surface, then the first wet-season soak leaves a white bloom. This is cosmetic, not structural, but it alarms owners. We can clean and re-seal affected fields after checking for irrigation overspray that’s feeding the cycle.
- Edge restraint heaving at driveway aprons and pasture gates. Heavy truck and trailer traffic loads a base that was compacted for foot traffic only. Edging then lifts and the field’s outer course drifts. We reset edges with proper Unilock restraints and deeper base at load points.
- Retaining wall rotation on sloped ranch terrain. Unilock Estate Wall blocks are only as good as the footing and drainage behind them. On San Martin parcels where a slope was cut for a pad or arena, walls can rotate if backfill drainage wasn’t built. We repair the wall and the water problem together.
Unilock Service in San Martin: What Local Conditions Mean for Your Equipment
San Martin is an unincorporated Santa Clara Valley community of horse properties and small ranches, so construction here is dominated by agricultural and equine structures – barns, arenas, tack rooms, shops, and pole buildings – plus the accessory dwellings and additions that come with large rural lots. A paver driveway in San Martin rarely just connects a garage to the street. It runs from the road past barns, tack rooms, and arenas over ground that was graded for grazing and drainage, not for vehicle loads. That means the base excavation and compaction depth – not the paver choice – decide whether the install holds. We see this on properties along San Martin Avenue all the time: a compacted gravel lane that worked fine for a pickup fails within two seasons once a horse trailer uses it weekly. Our Gilroy Unilock service team sees the same pattern on rural parcels there. On one multi-acre horse property off San Martin Avenue, the owner wanted a Brussels Block driveway running from the gate past the barn to a new shop, and the old ag pad underneath had never been compacted for truck and trailer traffic. We stripped the pasture gradings back, re-built the base to depth with proper drainage shed toward the swale, and set the field with Unilock edge restraint – it has taken a wet winter and a horse trailer without a single rocking unit. Good construction doesn’t announce itself – it just works, year after year.
Unilock Models & Products We Service in San Martin
We install and repair the full range of Unilock paver and wall systems, including Brussels Block, Beacon Hill Flagstone, and Holland Stone pavers, plus the Estate Wall retaining system. For repairs we use Unilock’s own pavers, edge restraints, and polymeric sand – the color lots and thickness tolerances have to match what’s already down, and mixing brands on a repair shows. When a base is sound we reset and re-sand the existing field; when the subgrade has pumped or a wall has rotated, we re-excavate rather than veneer over a failing structure. Our San Martin service area coverage means we keep common Unilock paver profiles and restraint types on hand for faster turnaround on ranch and residential repairs.

AfterUnilock Service Pricing in San Martin
Most Unilock projects in San Martin involve paver driveways, patios, or a full driveway replacement on rural parcels where extra base work is often needed. Here’s what we typically see:
| Project | Typical San Martin Range |
|---|---|

What drives cost here is base preparation. If excavation hits old ag pad material or expansive clay, we go deeper and bring in more aggregate. That’s the line item that changes a bid on a San Martin ranch versus a tract lot. A free estimate includes a site walk where we check drainage, measure the load path, and identify any base failures before we quote a number. Call (866) 472-1908 to schedule one.

FAQs – Unilock Construction in San Martin
Usually no – not without stripping it first. Old ag pads in San Martin were graded for drainage and light equipment, not compacted for truck and trailer loads. Setting pavers on top of that is how you get rocking units within a season or two. We excavate to stable subgrade, re-compact in lifts, and then set the field. Call (866) 472-1908 and we’ll assess the pad before any quote.
Often yes, because San Martin is unincorporated Santa Clara County, and the County reviews grading and drainage changes – especially on larger parcels where a new driveway changes runoff patterns toward a swale, barn, or neighboring property. We handle the grading plan and submittal as part of the project. For specifics on your parcel, call (866) 472-1908.
Fine if the drainage is right. The problem is when a driveway sheds water toward a barn or arena instead of a defined swale. Then winter rains push through the joints and wash out polymeric sand. We re-grade the drainage path before re-sanding, which is the only way the joints stay intact long-term. Call (866) 472-1908 for a drainage and joint assessment.
No. That’s efflorescence – mineral salts rising to the paver face after a hot San Martin summer followed by the first wet-season soak. It’s cosmetic, and in many cases irrigation overspray is feeding it. We can clean and re-seal the field, but first we check the water source so the problem doesn’t come right back. Call (866) 472-1908 for a look at the affected area.
Yes, if the base is sound and the existing product line is still in production. We match Unilock’s color lots and thickness tolerances using the same product line, because mixing brands on a repair shows. If the base has failed or the field has shifted, a repair won’t hold – we’ll tell you plainly and re-excavate instead. Call (866) 472-1908 and we’ll tell you which path applies.
