Unilock Construction in Los Altos Hills, CA | Moreno Valley Builders
We provide independent Unilock hardscape construction and repair across Los Altos Hills, from long private driveway approaches to hillside patios and fire-hardened entry aprons. The one thing that separates our Unilock work here is that we read each lot’s grade, drainage path, and fire-clearance envelope before specifying a single unit. With a one-acre minimum lot size shaping nearly every property in town, most of the Unilock fields we install and repair in Los Altos Hills are measured in hundreds of feet, not city-size front aprons. Call (877) 752-3154 to schedule a site walk and written estimate.
Why Los Altos Hills Residents Choose Us for Unilock Service
We know Unilock’s product lines the way a framing contractor knows lumber grades. Our crews work with Unilock sales & service products regularly: Brussels Block, Brussels Dimensional, Thornbury, and Beacon Hill. We specify each for specific conditions. Thornbury’s longer-format units read well on wide hillside terraces, while Brussels Block handles driveway aprons and transition zones where turning tires test edge restraint. Noel Trevino, our owner and general contractor, spent three decades building and remodeling across California hillsides before turning his attention to what happens at grade level. “If the details aren’t right on paper, they won’t be right in the wall” applies doubly to pavers, where the detail you can’t see is the base underneath.
Because we’re not tied to any manufacturer program, our recommendations come from what holds up on these slopes. We’re an independent installer and Los Altos Hills General Contractor, not a Unilock-authorized dealer. That distinction means we can tell a homeowner in Los Altos Hills when a paver field isn’t worth saving and when a base rebuild is the only honest fix.

Common Unilock Construction Problems We Solve in Los Altos Hills
Unilock pavers are well made. The failures we walk into in Los Altos Hills tend to live underneath them, at the edge, or in the drainage path. These are the five we see most often:
- Joint-sand loss on long driveway aprons. When runoff from a private lane sheets across the paver field instead of daylighting to a designed outlet, water lifts sand from every joint it crosses. After two or three wet seasons, the field loosens, units shift, and weed seed finds a home. We correct the slope and rebuild the edge before re-sanding.
- Efflorescence and base saturation on patios set into hillside cuts. Los Altos Hills sits on expansive soils along the eastern slopes of the Santa Cruz Mountains. Winter moisture wicks up through the bedding layer, leaving white mineral blooms on patio surfaces. That’s a symptom, not the disease. The disease is water sitting under the units with nowhere to go.
- Heaving and unit shift next to fire-hardened structures. Defensible-space clearing often trims excavation depth near the home. A shallow base, expansive soil, and winter moisture cycle together produce differential movement that shoves units out of plane.
- Rutting where pavers meet a gravel private lane. Delivery and service trucks load the transition point where the paver field ends and the gravel begins. Without a stabilized base under that interface, settlement and rutting show up within two years.
- Edge-restraint creep on sloped aprons. Loose or undersized edge restraint lets the entire field drift downhill over time. On Los Altos Hills grades, that drift is measurable every season. We use Unilock’s own restraint systems because generic substitutes fail faster on these slopes.
Unilock Service in Los Altos Hills: What Local Conditions Mean for Your Equipment
The one-acre minimum lot size in Los Altos Hills changes how Unilock driveways are designed, installed, and repaired compared to every neighboring city. In Palo Alto or Mountain View, a driveway apron runs twenty or thirty feet to a public curb. In Los Altos Hills, the paved approach often runs three, four, five hundred feet from the house to the street, crossing grade changes, drainage swales, and sometimes a private lane that the town classifies as fire-access-only. That means a paver field here can’t be treated like a flat suburban front apron. We design cross-slopes and base depths over the full run, not just at the garage. On a long private lane off La Paloma Road, our crew rebuilt a paver driveway apron where the original field had crept downhill and lost joint sand every wet season. We pulled the edge restraint, over-excavated to a compacted aggregate base, added drainage to daylight runoff before it reached the pavers, and re-set Brussels Block with fresh polymeric joint sand. That homeowner finally had an approach that shed water instead of swallowing it. Staging matters too. We position pallets and base aggregate at the street because many of these private lanes can’t carry a loaded delivery truck without rutting the very surface we’re about to rebuild.
Unilock Models & Products We Service in Los Altos Hills
We install and repair all the major Unilock paver and wall lines homeowners in Los Altos Hills specify: Brussels Block, Brussels Dimensional, Thornbury, and Beacon Hill. We also handle Unilock repair in Los Altos for the same product lines. When a field is failing, we diagnose base and drainage first. Most of what looks like a paver problem is a base problem, and replacing units without fixing drainage just resets the clock. For repairs, we use Unilock’s own restraint and joint-sand systems rather than generic substitutes, because on these grades the edge detail is what keeps the field locked. We carry common joint-sand and edge-restraint inventory at our local staging yard, which shortens turnaround when a Los Altos Hills repair can’t wait through a wet season.

FAQs – Unilock Construction in Los Altos Hills
Because runoff from long private lanes sheets across the paver field instead of daylighting to a designed outlet, it lifts sand from every joint it crosses. On a hundred-foot run of grade, that adds up quickly. We fix it by re-grading the cross-slope, restoring edge restraint, and re-sanding with Unilock’s polymeric product. Call (877) 752-3154 if you’re seeing bare joints and shifting units.
Often no, and that’s a planning problem, not just an inconvenience. We stage pallets and base aggregate at the street and shuttle material with smaller equipment when a lane can’t carry a loaded truck. We’ll assess access on the first site walk and tell you honestly what can and can’t be done.
Yes. Defensible-space clearing often trims excavation depth near the home, which means the base we install there has to account for a shallower section without creating a trip hazard or a heave point. We design base depths around the fire-clearance envelope, not through it.
Deeper than a flat-lot install in the valley. On expansive soils along the eastern slopes, we typically over-excavate to a compacted aggregate base of at least 6 to 8 inches under driveways, more where soils are unstable. A shallow base on a hillside is a heaving field waiting for the next wet winter.
It can, and it should be designed that way. We grade the field so water moves toward a designed outlet rather than pooling against the house or saturating the base. Los Altos Hills’ drainage rules and canyon topography make this a first-order design question, not an afterthought. Call (877) 752-3154 for a free estimate that includes a full drainage review.
