Unilock Construction in Los Altos, CA | Iron Beam Contractors
We install, repair, and rebuild Unilock paver driveways, patios, and walkways across Los Altos, CA, and offer our General Contractor in Los Altos services for full-project coordination. Most of our work here involves correcting failed installations that didn’t account for the town’s expansive clay soils or heritage-tree root zones. If you’re pricing a Unilock project in Los Altos, call (833) 756-5936 and we’ll give you a straight answer on what it takes to make it hold. We’re an independent Unilock installer, not a manufacturer-authorized dealer, which means we choose the right Unilock product for your site instead of pushing whatever’s in stock.
Why Los Altos Residents Choose Us for Unilock Service
We’ve torn out enough failed paver work in Los Altos to know exactly what goes wrong and when. The pattern is almost always the same: someone compacted the base too fast, ignored the clay layer underneath, and didn’t plan for what the tree roots would do in five years. We fix that.
Nolan Driscoll, who leads our team, learned structural work the hard way, framing and pouring across Orange County for two decades before starting Iron Beam Contractors. His principle is simple: “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.” That same discipline applies to every Unilock paver we set in Los Altos.
We carry genuine Unilock edge restraints, polymeric joint sands, and permeable aggregate blends matched to the specific paver profile and the drainage load it’ll face. No generic substitutes. No shortcuts on base depth. Unilock sales & service is what we do, and we’ve done it on enough Los Altos lots to know what the soil will do before the first paver goes down.

Common Unilock Construction Problems We Solve in Los Altos
- Clay-soil heave under driveways. Los Altos sits on expansive clay that swells in winter and shrinks in summer. When the base is under-compacted, that movement pushes Unilock pavers out of plane, causing rocking and joint-sand loss after the first wet winter. We over-excavate and compact in lifts to stop the heave before it starts.
- Heritage-tree root intrusion. Mature valley oaks and redwoods near lot lines will lift Unilock patio and walkway edges within a few years if the base depth isn’t planned around them. We see this constantly in the Country Club area and along older streets in Los Altos. Proper edge restraints and root-zone-aware base design are the fix, not just adding more sand.
- Drainage failures on sloped lots. A Unilock installation that doesn’t respect Los Altos’s impervious-surface rules ponds water against foundations during winter rains. That leads to efflorescence, settlement, and in the worst cases, water pushing into the crawlspace.
- Permeable paver clogging. Unilock Eco-Priora systems installed without proper geotextile and aggregate layers silt up fast in Los Altos’s dry-season dust. Infiltration stops, the pavers look tired, and the whole point of a permeable system is lost. Vacuum re-conditioning works short-term, but the real fix is rebuilding the aggregate cross-section correctly.
- Failed edge restraints. When a Los Altos paver driveway starts losing pavers at the perimeter, it’s usually because someone used a plastic restraint that couldn’t handle the clay movement or root pressure. We replace with Unilock’s genuine edge system, matched to the paver profile and pinned properly.
Unilock Service in Los Altos: What Local Conditions Mean for Your Equipment
Here’s the thing most out-of-town contractors don’t understand about Los Altos: the town enforces its impervious-surface and heritage-tree ordinances together. That changes what a Unilock project actually is. A permeable paver driveway or patio can satisfy both the site-coverage limit and the root-zone protection requirement, but only if it’s designed with the town’s tree-protection plan before the first paver goes down. On a rebuild in the Country Club neighborhood near the Los Altos Golf & Country Club, we installed a Unilock Eco-Priora permeable driveway where a mature valley oak sat within the root-protection zone, similar to our Unilock service in Stanford on heritage-tree properties. Our crew excavated by hand to avoid damaging the oak’s structural roots and laid the open-graded base and Unilock edge restraints. The driveway met the town’s impervious-surface calc and the arborist’s root-zone plan without a single tree-protection violation. That’s the difference between knowing the Los Altos Municipal Code and reading it for the first time at the permit counter.
Unilock Models & Products We Service in Los Altos
We work with Unilock’s structural and permeable paver lines, including Brussels Block, Beacon Hill, Town Hall, and Eco-Priora. Each has a different joint profile, base requirement, and drainage behavior. Brussels Block is our go-to for driveways that need to hold up under vehicle load on Los Altos clay. Beacon Hill and Town Hall suit patios and walkways where the look matters as much as the structure. Eco-Priora is the line we specify when the project has to reduce impervious surface to satisfy the town’s floor-area-ratio and site-development rules. We keep genuine Unilock edge restraints and matching polymeric sands on hand so we’re not chasing parts across the Bay Area when a Los Altos project needs to move.

What drives the cost in Los Altos is almost always the base repair. If we’re replacing a failed driveway, we’re not just laying new pavers on the old base. We’re over-excavating the clay, re-compacting in lifts, adding the right aggregate, and installing Unilock’s edge system. That’s why a driveway replacement lands where it does. Your free estimate includes a site walk, a look at what’s under the surface, and a written line-item quote. Call (833) 756-5936 and we’ll come out.

FAQs – Unilock Construction in Los Altos
Yes, a Unilock Eco-Priora permeable driveway can count toward reducing impervious surface on your Los Altos lot, which matters when the town’s floor-area-ratio and site-development rules are applied to a remodel or rebuild. The key is that the design has to be submitted with a tree-protection plan and approved before installation. We’ve done exactly this on Los Altos projects where a mature tree sat inside the root-protection zone and the permeable assembly satisfied both requirements. Call (833) 756-5936 and we’ll walk you through what a compliant design looks like for your specific lot.
Los Altos’s expansive clays swell in winter and shrink in summer, which means any Unilock installation needs a deeper, better-draining base than a typical Bay Area project. Under-compacted clay heaves the pavers out of plane, and once that starts, the joint sand washes out and the system fails. We over-excavate, compact in lifts, and use the right aggregate cross-section for the specific soil we find on site.
Most Unilock paver work that changes site coverage, grading, or is tied to a remodel will require design review and possibly Planning Commission approval in Los Altos. The discretionary review process applies to most new hardscape on single-family lots, especially when the project touches impervious-surface limits or tree-protection zones. We don’t pull the trigger on a design until we know what the town will accept.
For a structural driveway on Los Altos clay, we typically specify Brussels Block because of its dimensional stability under vehicle load. If the project needs to reduce impervious surface to comply with the town’s site-development rules, Eco-Priora is the better choice. Both require proper base prep, and we’ll spec the aggregate and edge restraint to match the Unilock profile and the drainage load. Call (833) 756-5936 for a site-specific recommendation and a free estimate.
When the base is intact and the settlement is localized, we repair the affected section by lifting pavers, re-compacting the aggregate, and resetting the edge restraint. If the failure is widespread or the original base was too shallow for Los Altos’s clay, we recommend a full rebuild with the correct Unilock assembly. We’ll tell you which one you’re dealing with before we write the quote. Call (833) 756-5936 and we’ll come look.
