Why Palo Alto Residents Choose Us for Unilock Service

Unilock pavers fail for predictable reasons in Palo Alto, and most stem from what’s under them, not the units themselves. A Brussels Block paver is a solid piece of concrete; the failure is almost always the base, the edge restraint, or the joint sand. We’ve built and rebuilt enough Unilock work across 94301, 94302, 94303, and 94304 to know exactly how each failure mode shows up here, and we spec the fix to Unilock’s own installation guides, not to whatever is fastest to patch. We also offer Unilock service in West Menlo Park for the same issues.

Nate Burrell, our owner and general contractor, has spent the better part of two decades on job sites throughout the South Bay, and he’s the kind of contractor who reads installation specs before opening a trench. He trained in construction technology at Gavilan College and grew up around framing crews in Morgan Hill, and that’s the standard we bring to every Palo Alto paver repair: do it once, do it right, everything else is just a future repair bill. Since we also operate a full-stack Unilock sales & service practice across interior and exterior work, you’re not handing your hardscape to a crew that only knows pavers; you’re getting a general contractor who treats the whole property as one system.

Common Unilock Construction Problems We Solve in Palo Alto

• Washed-out polymeric joint sand. Palo Alto’s rain comes almost entirely between November and March, and when it falls on a low-pitch Eichler roof, it exits fast through the downspout and scours across any paver surface below. Open joints follow within a season or two. We re-sand with a stabilized joint compound and, where the grade allows, redirect the roof drainage first so it doesn’t come back.
• Efflorescence on Brussels Block faces. That white bloom looks like a surface stain, but it’s usually moisture trapped under the bedding layer working its minerals upward – often because the base wasn’t compacted to Unilock’s lift spec during a compressed dry-season install. We can’t stop Palo Alto’s wet winters, but we can rebuild the base so water drains through instead of pooling under the units.
• Edge restraint failure at curb cuts. The driveways along El Camino and many side streets bear vehicle loads that climb unevenly at the curb transition. Grass edge restraints fail under that loading, especially where old tree roots have lifted the base. We pull the edge back, reset proper paver edge restraint, and re-establish the slope.
• Permeable Town Hall installations choked by silt. Palo Alto pushes permeable paving hard as a stormwater tool, but a Town Hall system only works if the open-graded aggregate reservoir under it is sized right and flushed regularly. Fine silt from surrounding landscaping beds migrates in and chokes the void space, turning a permeable field into an expensive puddle. We diagnose flow rates and rebuild the reservoir as needed.
• Sunken units at the garage lip. This is the classic Greenmeadows case: runoff from a flat roof scours the joint material, the base settles, and the first two courses of driveway pavers drop at the garage apron. We lift, re-excavate, and reset rather than quote a full replacement unless spalling says otherwise.

Unilock Service in Palo Alto: What Local Conditions Mean for Your Equipment

The single biggest factor in a Unilock installation holding up in Palo Alto is the compression of the construction calendar. This city’s dry season runs roughly April through October; rain from November through March is more than occasional, and it comes in concentrated bursts. That means a paver driveway or patio here has to be excavated, base-built in lifts, compacted, and surfaced within one continuous window. Leave an open excavation even a week too long and the first November storm will soak the open-graded aggregate, soften the subgrade, and undermine compaction before a single paver goes down. We’ve seen this happen on properties across the Palo Alto service area – the fix isn’t just adding more base, it’s scheduling the whole operation around the weather window and building in drainage from the first cut.

In Greenmeadows, we rebuilt a Brussels Block driveway apron where winter runoff off a flat foam roof had scoured the polymeric sand and dropped two courses of pavers at the garage lip. We pulled the units, re-excavated to a deeper compacted aggregate base, reset the edge restraint, and re-sanded with stabilized joint sand. The field pavers were reused; only four spalled units were replaced. That is the difference between a contractor who rebuilds to a spec and one who patch-jobs around a problem.

Unilock Models & Products We Service in Palo Alto

We install and repair the full spread of Unilock product lines that homeowners in Palo Alto actually specify. Brussels Block and its tumbled, worn-in character is the workhorse for driveways and walkways. Beacon Hill Flagstone carries the more irregular, natural-stone look that fits mid-century landscaping in Midtown. Town Hall is the permeable series we see requested when the city’s stormwater requirements push owners to treat more runoff on-site. Brussels Dimensional Stone is the wall unit we set for low retaining walls and planter borders. For every series, we use genuine Unilock units for visible surfaces so course thickness, chamfer, and color blend match exactly. For the hidden layers – base aggregate, edge restraint, joint sand – we use spec-compliant material, because that’s where the failure lives or dies, and the brand sticker doesn’t matter six inches underground.

FAQs – Unilock Construction in Palo Alto

Can we keep our existing Unilock Brussels Block pavers and just fix the sunken areas?
Yes, and we do it often. Brussels Block is a dense, durable unit that usually outlives its base. We lift the affected field, re-excavate and compact a proper aggregate base, reset the edge restraint, and re-sand – reusing the original units wherever they’re structurally sound and color-matched. Only spalled, cracked, or badly faded units get replaced. Call (833) 725-3508 and we’ll tell you whether your field is salvageable.

How does Palo Alto’s rainy season affect a new Unilock patio installation?
It determines the build window. Between November and March, Palo Alto gets almost all its rain, and an open paver base is a liability in a wet trench. We schedule new Unilock patio installations so the entire base and surface go in before the season turns; if rain is forecast mid-install, we tarp and re-compact before bedding. Starting the project at the wrong time is the single easiest way to guarantee settlement later.

Do we need a permit for a Unilock paver driveway or patio in Palo Alto?
Often, yes. Palo Alto reviews hardscape projects for stormwater compliance, and permeable systems like Unilock Town Hall can actually help your permitting position – but the details depend on your lot’s impervious-surface ratio and any reach-code conditions tied to the property. We pull permits on every job that needs one and we’ll tell you at the estimate stage what applies to your specific address.

Will Unilock permeable pavers help with Palo Alto stormwater rules?
They can, if the system underneath is right. Town Hall and other permeable Unilock units let water pass through the surface, but Palo Alto’s stormwater rules care about what happens below the paver: the open-graded reservoir, the infiltration rate, and the outflow path. A properly sized and flushed system can help meet the city’s runoff reduction expectations. A badly built one is just a clogged puddle with a Unilock top. We build to the hydraulics, not just the look.

What causes white powdery stains on our Unilock pavers and does it come back?
That’s efflorescence, and it’s driven by water moving upward through the paver’s capillaries, carrying dissolved minerals to the face. In Palo Alto, the trigger is almost always a base that wasn’t compacted in lifts or drained properly, so the first winter traps moisture under the bedding layer and the bloom shows up in spring. If we fix the base and the drainage, the efflorescence typically doesn’t return; sealers slow it but don’t fix the real problem. Call (833) 725-3508 for an assessment.
