Unilock Construction in San Martin, CA | Toolbox Contractors
We install, repair, and rebuild Unilock paver patios, driveways, and retaining walls across San Martin as an independent hardscape crew. What makes our Unilock work different here comes down to what’s under the pavers: expansive former-orchard clay, buried irrigation lines, and county-governed permitting that most contractors from Morgan Hill or Gilroy never deal with. If you’re planning a Unilock patio or driveway in San Martin, call (855) 382-3257 for a free estimate and we’ll tell you exactly what the soil will demand before we cut anything.
Why San Martin Residents Choose Us for Unilock Service
We’ve been setting Unilock pavers long enough to know that a paver is only as good as the base beneath it. That’s the whole ballgame in San Martin. Norm Castellano, our owner at Toolbox Contractors, grew up around half-finished houses and learned construction the hands-on way through San Bernardino Valley College’s construction technology program before spending close to two decades framing, roofing, and rebuilding kitchens across the Inland Empire. When he talks about base prep on expansive clay, it’s because he’s pulled up enough failed paver jobs to know exactly what shortcuts cause them.
We’re independent. No factory authorization, no brand badge. Our credibility comes from Unilock installations that stay flat and tight on San Martin parcels where other crews’ work has heaved, settled, or washed out. Tell me what you’ve got and we’ll tell you what it actually needs. That’s how we’ve always worked. Our Unilock sales & service work spans the full scope: new patio construction, driveway replacement, edge restraint fixes, and full base rebuilds when the clay wins.

Common Unilock Construction Problems We Solve in San Martin
- Efflorescence on Brussels Block and Cambridge pavers. San Martin’s winter rains saturate the clay-heavy former orchard soils, and when that moisture wicks up through the paver, it leaves white chalky mineral deposits on the surface. It usually signals a drainage problem at the base, not a defect in the paver itself. We fix the drainage and clean the bloom.
- Settlement and rocking pavers on Lineo and Cambridge patios. If the original crew skimped on aggregate base depth, expansive clay will heave and shift those pavers within a season or two. We see it constantly on San Martin ranch properties. The fix is pulling the field, re-cutting the base properly, and re-laying with compacted aggregate.
- Joint sand washout along driveway aprons. After a wet winter, driveway borders spread and pavers drift when edge restraints fail and joint sand washes out. On San Martin driveways that slope toward the road, this shows up first at the apron. We re-set the restraint, replace the sand with polymeric, and the field holds.
- Dulled ArmorTec surfaces and loosened wall caps. Hot dry summers with recurring wildfire concern mean ember exposure and heat cycling. Without polymeric joint sand, caps on Unilock retaining walls loosen and ArmorTec surface treatments dull faster. We rebuild those caps with the right joint material.
- Buried irrigation lines and old well casings under the base. Not a paver failure exactly, but it becomes one if you ignore it. On former orchard parcels across San Martin, excavation hits irrigation mains and well casings that shift drainage and destabilize the base. We locate and reroute before laying the field, which is why our work stays flat.
Unilock Service in San Martin: What Local Conditions Mean for Your Equipment
San Martin is unincorporated, which means Unilock driveway and patio projects here are permitted and inspected through Santa Clara County rather than a city building department. That alone changes the job. County reviewers look at drainage, grading, and fire-hardening in ways a city inspector handling Morgan Hill Unilock service might not. But the real wildcard is what’s buried on former orchard parcels. We’ve hit irrigation mains, shallow well casings, and old pipe runs during base excavation on more than one San Martin driveway. That discovery forces a redesign: how deep we can cut, where the drainage runs, whether the paver layout shifts. On a one-acre ranch parcel off Llagas Road, we tore out a cracked concrete apron and set a Unilock Cambridge ArmorTec paver driveway with a proper compacted aggregate base and polymeric joints. During excavation our crew struck an old orchard irrigation line and a shallow well casing, so we rerouted the drainage and re-graded away from the shop before re-laying the field. Two wet winters later the pavers are still tight at the edges with no washout. That’s what local knowledge buys you.
Unilock Models & Products We Service in San Martin
We work with the Unilock lines that dominate San Martin hardscape jobs: Brussels Block, Cambridge Pavingstones with ArmorTec, Beacon Hill Flagstone, and the Lineo permeable patio slab system. For repairs, we source genuine Unilock units and matching edge restraints so color and thickness align with the existing field. No substitute blocks, no mismatched borders. We keep a working stock of polymeric joint sand and compacted aggregate base on hand for San Martin jobs, which means we’re not waiting on a supply house run to start a repair. When you need a paver patio installed or a driveway rebuilt, we quote the real Unilock product and stand behind the install.

FAQs – Unilock Construction in San Martin
Yes. Because San Martin is unincorporated, driveway and patio projects go through Santa Clara County planning and building, not a city desk. The permit often triggers a drainage and grading review, especially on parcels with expansive soils or wildland-urban interface requirements. We handle the paperwork and the inspections as part of the job. Call (855) 382-3257 and we’ll tell you what your specific parcel will require.
That’s efflorescence, and in San Martin it’s usually the result of wet clay soils beneath the pavers pushing mineral-laden moisture up through the joints. The base isn’t draining. We fix the drainage, clean the surface, and re-joint with polymeric sand so it doesn’t come back. Call (855) 382-3257 for an assessment.
They can, but only if the base is built for it. Expansive clay moves when it gets wet and dries out. A proper compacted aggregate base with adequate depth absorbs that movement. Skimp on base depth and even the best Unilock paver will heave. We cut bases deeper on San Martin orchard parcels for exactly this reason.
Most San Martin paver patios run between $3,500 and $11,000 depending on size, base conditions, and whether we’re pulling out an old concrete slab first. Former orchard parcels with buried irrigation lines can add excavation costs. Call (855) 382-3257 for a line-item quote. Estimates are free.
Genuine. We source real Unilock units and matching edge restraints so color and thickness align with your existing field. We don’t patch a Unilock driveway with bargain blocks that don’t match. If a repair calls for a full base rebuild, we tell you that up front rather than bandaging it.
