Unilock Construction in Palo Alto, CA | Moreno Valley Builders
We provide independent Unilock installation, repair, and hardscape construction across Palo Alto, from Professorville to the Eichler tracts south of Oregon Expressway. The thing that separates our Unilock work here is simple: we build for Palo Alto’s tree ordinance, expansive clay pockets, and flat-roof drainage patterns first, then we pick the paver. If you’re pricing a paver driveway or patio in 94301, 94302, 94303, or 94304, call (877) 752-3154 for a free, line-item estimate.
Why Palo Alto Residents Choose Us for Unilock Service
We’ve installed and repaired Unilock systems long enough to know which lines earn their price and which ones don’t belong on a given Palo Alto lot. We’re an independent contractor, not a Unilock dealer or authorized warranty shop, so our recommendations aren’t steered by inventory. Noel Trevino, our owner and general contractor, grew up running jobs where the difference between a good install and a callback was the base preparation, not the paver on top. That’s the lens we bring to every Unilock driveway, walkway, and patio in Palo Alto. We source Unilock sales & service components directly when OEM matters, and we’re not shy about specifying a better aftermarket geotextile or aggregate when it outperforms what the manufacturer ships.
One contractor handles the whole scope: excavation, base, drainage, edge restraint, paver setting, and the final inspection. You’re not coordinating a paver crew in one week and a drain guy in another. We manage the trades so you don’t have to.

Common Unilock Construction Problems We Solve in Palo Alto
- Base settlement and paver heaving. South Palo Alto’s Eichler tracts sit on pockets of expansive clay that swell with winter rain and shrink through the dry summer. When a paver base isn’t over-excavated and stabilized, Unilock units lift, rotate, and lose joint sand after the first wet season. We pull the section, fix the base, and reset the pavers rather than patching the symptom.
- Efflorescence and joint erosion where flat-roof downspouts discharge onto paver fields. Eichler scuppers and flat-roof drains often dump water directly onto the paving. Without a positive slope or a collection channel, that concentrated flow washes out polymeric sand and leaves chalky mineral staining on the paver surface. We re-grade the base and add drainage before resetting.
- Edge restraint failure near heritage oaks and redwoods. Root growth lifts and misaligns pavers along the perimeter, especially where shallow-rooted trees crowd a driveway or patio in north Palo Alto. A proper edge restraint and root barrier installation keeps the field locked in, but it has to be done before the pavers go down.
- Surface staining from tannin and UV fade. Heavily shaded lots in north Palo Alto, particularly under mature oaks, get tannin runoff that dulls lighter Unilock color blends. We clean and re-sand sound pavers where possible, and we’ll tell you honestly when a color choice is working against the site.
- Misaligned units from utility trench settling. The soil over a PG&E or water line trench was often poorly compacted when the house was built. Pavers laid across that line settle in a visible stripe. We over-excavate and install a geogrid-reinforced base so the field stays flat, even over the trench.
Unilock Service in Palo Alto: What Local Conditions Mean for Your Equipment
Here’s the Palo Alto-specific reality that doesn’t apply in Mountain View or Menlo Park: the city’s tree-protection ordinance covers not just heritage oaks but designated redwoods, and on many lots the drip-line root zones extend into the only viable driveway or patio area. That means a Unilock layout often has to be redesigned with hand-dug base trenches and root barriers before a permit is even issued. We’ve walked into backyards in Professorville where the proposed paver patio sat entirely inside a protected oak’s root zone. The fix wasn’t a different paver, it was a smaller footprint with a root-bridge detail and a revised drainage plan. On a recent job in the Eichler tracts south of Oregon, our crew replaced a failing paver driveway where original Unilock service in West Menlo Park and surrounding areas had installed Brussels Block that settled unevenly due to uncompacted fill over utility trenches. We removed and salvaged the pavers, over-excavated 18 inches, installed a geogrid-reinforced base with a positive drain to the street, and re-set the pavers with new edge restraints. The homeowner now has a stable driveway that ties into the original flat-roof scupper drainage without ponding. That’s the difference between a paver job and a Palo Alto paver job.
Unilock Models & Products We Service in Palo Alto
We work across the Unilock lines that make sense for Palo Alto’s housing stock: Brussels Block for traditional north Palo Alto bungalows, Brussels Dimensional for cleaner geometric layouts, Elegance for larger patios and pool decks, and Il Campo for a more contemporary, flagstone-like surface that suits mid-century Eichler aesthetics. When a Unilock unit is still structurally sound but showing surface wear, we honest-repair and re-sand rather than pushing a full replacement. For base and drainage components, we specify quality aftermarket geotextiles and compacted aggregate that outperform standard builder-grade materials. For edge restraints and polymeric joint sands, we use Unilock’s own OEM product where the spec calls for it, including on Emerald Lake Hills Unilock service projects. That’s the right balance: OEM where the brand matters, aftermarket where the soil and drainage don’t care about a logo.

FAQs – Unilock Construction in Palo Alto
Palo Alto’s tree ordinance protects mature oaks and designated redwoods, and any construction within a protected tree’s drip line requires review and often a root-protection plan. That can shrink your paver footprint, change the base design, or require hand-dug trenches instead of machine excavation. We handle that planning upfront, and we’ve navigated enough Palo Alto tree reviews to tell you early whether the layout you want is the layout you’ll get. Call (877) 752-3154 to talk through your specific lot.
Sometimes. If the slab is sound and the grade works, we can overlay Unilock pavers on a concrete base. The catch in Palo Alto is often drainage: a flat Eichler slab with no slope traps water under the pavers, which leads to efflorescence and joint failure. We’ll tell you within one site visit whether an overlay is viable or whether the old slab needs to come out.
For Eichler homes, we usually recommend Il Campo or Brussels Dimensional in a muted gray or charcoal blend. Il Campo’s larger, irregular flagstone profile reads more architectural and less suburban than a tumbled paver. Brussels Dimensional gives a cleaner grid that complements post-and-beam geometry. We’ll bring samples to your Palo Alto site so you can see them against your original siding and concrete.
Flat-roof scuppers concentrate a lot of water in one spot. We slope the paver field away from the house and install a collection channel or strip drain where the scupper discharges, so the water moves to the street or a dry well instead of eroding the joint sand. If we’re replacing a failed paver field, that drainage correction is usually the single most important part of the job. Call (877) 752-3154 for an exact scope and pricing.
Plan on a polymeric sand top-up every two to three years, and a cleaning every spring after the winter rains stop. Palo Alto’s October-to-April wet season pushes silt and tree debris into the joints, which loosens the sand and can start the settlement cycle. We do maintenance re-sanding for Unilock fields across the 94301 and 94303 ZIP codes and offer Unilock in Los Altos Hills as well, and we’ll give you a realistic maintenance interval based on your tree cover and drainage.
