Unilock Construction in San Martin, CA | Iron Beam Contractors
Unilock paver and retaining wall work in San Martin runs $3,500 to $18,000 for most driveways and patios, and the one thing that changes the job here more than anywhere else is what’s underground: septic leach fields, wells, and expansive clay. We’re an independent Unilock service provider covering San Martin and the surrounding Santa Clara Valley, and Nolan Driscoll built Iron Beam Contractors so homeowners get one accountable contractor from excavation to final joint sand. Call (833) 756-5936 for a free estimate on your San Martin hardscape.
Why San Martin Residents Choose Us for Unilock Service
We install Unilock pavers and retaining wall systems on San Martin’s large rural parcels, and we know how these units behave on expansive clay and long graded access runs. Because we’re independent, we specify the Unilock profile that fits your grade, drainage, and county permitting rather than being tied to one sales program. That’s the difference between a paver field that holds its line through three wet seasons and one that heaves at the soldier course by February.
Nolan spent years in this region’s soil, grade, and clay layers before he ever touched a beam, and that’s exactly the kind of hands-on knowledge you want when someone’s about to excavate near your septic system. Our crew has reset enough failed paver fields in San Martin to know what holds and what doesn’t. We carry genuine Unilock units and compatible edge restraints, polymeric joint sand, and geotextile from quality suppliers, not off-brand lookalikes that won’t match thickness or color. If you want Unilock sales & service done right the first time, we’re the team that knows what’s in the ground before we open it up.

Common Unilock Construction Problems We Solve in San Martin
- Efflorescence blooming on Brussels Block and Umbriano faces. San Martin’s wet winters push mineral salts up through the paver, leaving that white powdery bloom. We fix it by cutting proper base drainage, not just scrubbing the face. Without drainage work, the bloom returns next winter.
- Joint sand washout on long rural driveways. San Martin parcels often have steep grading or poor surface runoff, and water runs hard through paver joints. We replace washed-out sand with polymeric joint sand and add edge restraint so units stop migrating and lipping at the edges.
- Settlement and heaving on expansive clay. San Martin’s clay soil moves with seasonal moisture, and a base laid directly over clay will shift. We excavate to a compacted aggregate base with geotextile separation so the field stays level instead of opening gaps at the soldier course.
- Polysand erosion along pool decks and patio edges. Winter frost cycles and wildfire-season debris washing across San Martin surfaces erode joint sand fast. We re-sand and seal where the field is sound, and we replace only when the subbase has failed.
- Overlay failure on old concrete driveways. Paving over a cracked San Martin slab without addressing the clay movement underneath just transfers the cracks upward. We fix the base first, then lay the Unilock profile that fits the grade.
Unilock Service in San Martin: What Local Conditions Mean for Your Equipment
San Martin has no city hall. Every building permit, including hardscape permits for paver driveways and patios, runs through Santa Clara County, and most projects wait on well and septic sign-off before excavation can start. That’s not true twenty minutes up the road, where Morgan Hill Unilock service follows a different permitting path, and it changes how we schedule and scope Unilock work here. If your leach field sits on the east side of the parcel, your paver driveway can’t cross it, and we have to keep hardscape off drainfields and setbacks entirely. We’ve worked around this enough times to factor it into the estimate before we ever put a shovel in the ground. On one multi-acre parcel off a rural lane near San Martin, our crew tore out a heaved Brussels Block driveway apron where the old base had been laid directly over clay with no drainage. We excavated to a compacted aggregate base with geotextile separation, cut a drainage swale away from the septic leach field, and reset the field with new Unilock Brussels Block plus polymeric joint sand and proper edge restraint. The driveway came back level through the next wet season with no lippage at the soldier course. If the structure makes sense on paper, it’ll hold in the field. If it doesn’t make sense on paper, we fix it before we touch a beam.
Unilock Models & Products We Service in San Martin
We install and service the Unilock lines that hold up best on San Martin’s rural parcels, and we also provide Gilroy Unilock service to nearby communities. Brussels Block is our go-to for classic driveway and walkway work, a tumbled paver that hides wear well. Umbriano gives you that old-world finish for patios and driveways, and we’ve reset plenty of Umbriano fields where the joint sand had washed out. Beacon Hill is the flagstone-look patio paver we recommend when a homeowner wants a more natural surface. For retaining walls, we work with the Brussels Dimensional and Thornbury systems. We use genuine Unilock units and Unilock-compatible edge restraints, and we stock common profiles and polymeric sand locally so San Martin turnarounds don’t stall while parts ship from a distributor. When a field is 80% sound, we reset and re-sand rather than tear out. Full replacement only makes sense when subbase failure is widespread or the blend is discontinued.

FAQs – Unilock Construction in San Martin
Yes, in most cases. San Martin is unincorporated, so hardscape work with excavation falls under Santa Clara County permitting, and if your parcel has a well or septic system, those sign-offs often come first. We handle the permit path for you and tell you what’s needed before excavation starts. Call (833) 756-5936 and we’ll walk you through what your specific parcel requires.
That white bloom is efflorescence, mineral salts pushed to the paver surface by moisture moving through the base. In San Martin, our wet winters and expansive clay make it common on Brussels Block and Umbriano faces. The fix is drainage correction and proper base separation, not just surface cleaning. We’ll assess your patio and tell you if it’s a drainage problem or a maintenance issue.
Sometimes, but only if the underlying slab is structurally sound and the clay beneath it isn’t moving. On San Martin parcels with expansive soil, an overlay without base correction just transfers cracks upward through the new pavers. We’ll core a small section and tell you honestly whether an overlay makes sense or a full replacement is the better long-term call.
We map the leach field and setbacks before we design the hardscape, and we keep the paver field completely clear of it. San Martin parcels often have the leach field right where a driveway wants to go, which means adjusting the layout or the driveway path. It’s part of working on unincorporated county land, just as it is for Unilock in Corralitos, and we plan for it from the first site visit.
Umbriano holds up well on graded San Martin driveways with its tighter joint pattern, and Brussels Block works if the base and drainage are cut correctly. The paver line matters less than the base. On sloping rural parcels, we add geotextile separation, a compacted aggregate base, and edge restraint so the units don’t migrate. Call
