Unilock Construction in Mountain View, CA | Spruce Contractors
We are an independent Unilock installer serving Mountain View with paver patios, driveways, and retaining walls built to handle the city’s specific soil and drainage conditions. We are not manufacturer-authorized, and we do not pretend to be. What we bring instead is years of hardscape work on mid-century lots and newer infill across 94040, 94041, and the surrounding zip codes. Call (877) 265-5771 for a free estimate on your Unilock project in Mountain View.
Why Mountain View Residents Choose Us for Unilock Service
Most hardscape crews can set pavers. Far fewer understand what happens to Unilock units when they are installed over Mountain View’s expansive clay subgrade without proper excavation, or when finished grade is set too high against an Eichler’s floor-to-ceiling glass. We do, because we have been doing this work here long enough to see what fails and why. Nate Calloway, our owner, grew up in Hillsborough and learned construction at College of San Mateo before running projects across San Mateo County, so the local soil behavior is not something we learned from a brochure. We run our Unilock work with the same approach we use on our full-scope remodels: Unilock sales & service should be specific, accountable, and built on real product knowledge, not vague promises.
When your patio settles, we lift, re-grade, and relay your existing Unilock pavers before we ever suggest a full replacement. It is the right call for most Mountain View General Contractor lots, and it is usually less expensive for you.

Common Unilock Construction Problems We Solve in Mountain View
- Efflorescence haze and polymer joint-sand washout after winter rains. Mountain View’s wet season tests base drainage hard. When a patio or walkway was built with undersized base or no drainage swale, the first heavy storms push water through the joints and leave a white chalky residue across Brussels Block and Beacon Hill surfaces. We pull the joint sand, clean the units, and rebuild the base fall before relaying.
- Settling and lippage at driveway aprons and Eichler-side walkways. Much of Mountain View sits on expansive clay. If the subgrade was not excavated deep enough, pavers shift and lip at transitions. We see this constantly on Monta Loma driveways and walkways that run alongside mid-century homes. The fix is not more sand, it is a proper excavation and compacted base rebuild.
- Faded or chipped edges on tumbled Brussels Block at tight turning radii. Overdone pressure washing and de-icing products accelerate edge wear. Tight curves, like the turns on older Mountain View driveways, show chipping first. We can replace individual units with genuine Unilock pieces to keep color and dimension consistent.
- Retaining wall unit or capstone separation. When an Unilock wall goes up against a slope without geogrid, the wall starts to lean or separate at the caps within a few wet seasons. We see this on properties along the steeper lots near Crystal Springs Road and other hillside-adjacent Mountain View streets. We rebuild with proper grid reinforcement and drainage behind the wall.
- Radiant slab conflicts under paver work. In Monta Loma and other Eichler tracts, the original radiant heating tubes are embedded in the concrete slab. Any driveway or patio demo near the house has to respect those lines. We map them before we touch the slab, because hitting a radiant tube turns a paver job into a much bigger repair.
Unilock Service in Mountain View: What Local Conditions Mean for Your Equipment
Mountain View’s construction market splits between high-tech office build-outs and upgrades to the Eichler and other mid-century tract homes that fill neighborhoods like Monta Loma. That split matters for hardscape work in a way most people do not realize until something goes wrong. In Eichler neighborhoods, Unilock driveways and patios often have to be built up to meet the post-and-beam house without burying the original floor-to-ceiling glass line. That means finished paver grade is set a step below the glass and original slab rather than flush to it. Get that elevation slightly wrong and you either block the glass, which ruins the whole point of an Eichler, or you create a low spot that channels runoff toward the foundation. It is a detail that simply does not exist in newer infill homes along the transit corridors in 94041, where slabs are conventional and glass lines are not structural. If your paver contractor has not worked on mid-century lots, they will not check for this. We do, on every Mountain View job.
Unilock Models & Products We Service in Mountain View
We install and repair the Unilock lines most common on Mountain View properties: Brussels Block in tumbled concrete, Beacon Hill Flagstone for patios and walkways, Brussels Dimensional Stone for wall units, and the Thornbury permeable interlocking pavers for driveways where drainage matters more than usual. We stock common replacement units for fast turnaround on Mountain View repairs, and we source genuine Unilock pieces when color or dimensional matching is critical. For base material, we use quality compatible aggregate, geogrid, and polymeric joint sand, never the cheapest option off the shelf. We also handle full driveway replacements when the slab or base has failed beyond repair. Our Mountain View service area covers 94035, 94039, 94040, and 94041.

FAQs – Unilock Construction in Mountain View
In most cases, no. Eichler slabs in Mountain View carry radiant heating tubes and have specific elevation constraints against the floor-to-ceiling glass. Laying pavers directly over that slab buries the glass line and risks damaging the radiant system. We almost always remove the failing concrete, excavate properly, and rebuild the base below the existing grade. The one exception is a thin overlay on a structurally sound slab where elevation allows, which is rare on mid-century lots. Call (877) 265-5771 and we will assess your specific situation without charge.
That white haze is efflorescence, caused by water moving through the paver base and carrying mineral salts to the surface. In Mountain View, the rainy season is the trigger. It usually means the base drainage was undersized or the joint sand has washed out. The fix is to pull the affected joints, rebuild the base fall, and use a proper polymeric sand. We do this regularly on Mountain View patios and walkways, and offer the same Unilock repair in Los Altos.
Yes, in many cases. Mountain View requires permits for retaining walls over a certain height and for driveway work that changes grade or drainage patterns. We pull permits and handle inspections as part of the job, so you do not get a stop-work order or a code violation down the line.
They will, if the base is built correctly. Mountain View’s expansive clay moves with moisture, which is why base depth and compaction matter more here than paver color or pattern. We excavate deeper than the minimum on clay lots, use proper aggregate, and set the fall away from the house, just as we do for Unilock repair in Loyola. That is the difference between a patio that lasts 20 years and one that settles in three.
Yes. We source genuine Unilock units and matching caps, so color and dimension stay consistent with your existing patio, walkway, or wall. When a section has settled, we lift and relay the original pavers rather than sell you a full replacement. When individual units are cracked, chipped, or spalled beyond repair, we replace only those pieces. Call (877) 265-5771 for a quote on matching or repair.
