Unilock Construction in Cupertino, CA | San Mateo Construction

We’re an independent construction crew that installs and repairs Unilock hardscape systems throughout Cupertino, and the thing that separates our work here is how we handle two obstacles most contractors don’t see coming: expansive clay soil and the city’s heritage tree ordinance.

We are not authorized by or affiliated with Unilock, and we don’t pretend otherwise. What we bring is field experience with their full product line across Cupertino’s teardown-and-rebuild lots, where Unilock sales & service questions get more complicated than a standard install. From Brussels Block driveways on flat ranch lots to Estate Wall planter systems on sloped rebuild sites, we match the right product to the engineering reality of each property.

Why Cupertino Residents Choose Us for Unilock Service

Most Cupertino homes were built in the 1950s and 60s as single-story Eichler-era ranches. What’s happening now is a steady replacement cycle: those ranches come down, large two-story customs go up, and the hardscape has to integrate with basements, attached garages, and smart-home infrastructure. That integration is where generic paver installers fall apart.

Noel Carrington, our owner, grew up pouring concrete footings with his father in San Mateo County, and he’s spent three decades on residential and light commercial work across the Bay Area. He’s the one who walks every Cupertino site before we quote. Cupertino service area coverage means we’re already familiar with the design review board, the tree protection requirements, and the soil reports that shape what actually gets approved. We source genuine Unilock pavers and wall units when color and dimensional match matter, and we use aftermarket geogrid, drainage aggregate, and polymeric sands that meet or exceed spec where hidden components are concerned. That’s not cutting corners. That’s knowing which materials earn their cost.

Common Unilock Construction Problems We Solve in Cupertino

• Brussels Block pavers settling unevenly over expansive clay after wet winters. Cupertino’s clay soils swell when saturated and shrink when dry, and a paver base that wasn’t engineered for that movement will sink, rotate, and pool water near foundations. We lift, re-grade, compact, and relay with the right base depth. Patching the face of a failing base is money wasted, so we’ll tell you straight if the base needs full reconstruction.
• Estate Wall blocks cracking or bulging on sloped ranch-to-modern rebuild lots. The original walls on older Cupertino properties weren’t built with drainage that handles our rainy season, and when water builds up behind a retaining wall on a slope, the wall pushes outward. We install proper weep systems, backfill aggregate, and geogrid reinforcement to stop the movement at the source.
• Beacon Hill pavers showing efflorescence and surface spalling. Summer dust-control washing and winter rain cycling without sealing leave mineral deposits and surface damage that look worse every year. We match the existing paver dimensions and replace affected units, then seal if the homeowner wants the protection.
• Rivercrest wall units separating at joints on steep grades. Cupertino’s hillside properties put serious lateral load on modular retaining walls, and Rivercrest units installed without engineered geogrid separate at the seams. We rebuild the wall with proper reinforcement tied to the slope’s actual geometry.
• Permeable paver systems clogged by construction dust and clay runoff. On rebuild lots, the demolition and foundation work generates fine sediment that clogs paver joints and reduces drainage performance. We clean and restore the joint material so the system drains like it’s supposed to.

Unilock Service in Cupertino: What Local Conditions Mean for Your Equipment

Here’s something you won’t find on a generic Unilock page. Cupertino’s tree ordinance requires a permit to remove or even heavily prune heritage oaks and redwoods, and that single regulation changes how we design paver driveways and patios all over this city. When a protected tree sits where a driveway would logically go, you can’t just cut it down or pour around it. You design around the drip line, and you often switch to permeable Unilock pavers so the root zone keeps getting water and air.

On a teardown-rebuild lot near Eaton Elementary in the 95014 ZIP, the owner wanted a Unilock Brussels Block driveway and an Estate Wall planter. A heritage oak sat inside the proposed layout. We redesigned with a permeable Unilock paver band and a geogrid-reinforced Estate Wall set back from the drip line, then tied a French drain into the new basement waterproofing. Cupertino’s arborist signed off on the tree protection plan, and the wall has held through two wet winters. That’s the kind of site-specific thinking this city demands, and it’s exactly why we don’t quote over the phone without seeing the property first.

Unilock Models & Products We Service in Cupertino

We work with the full Unilock line that shows up in Cupertino yards: Brussels Block for driveways and walkways, Estate Wall and Rivercrest for retaining walls and planters, and Beacon Hill for patios with a clean flagstone look. Each family has different tolerances for base movement, drainage demand, and sealant needs, and we match the right one to your lot’s soil report and design constraints.

When a repair requires color-matched replacement units, we order genuine Unilock pavers from regional distributors so the patch doesn’t announce itself. For grid, aggregate, and joint sand below the surface, we use proven aftermarket materials that meet or exceed Unilock’s installation spec. We keep the common repair materials staged for quick Cupertino turnaround, but every repair starts with a site visit so we’re not guessing at base conditions through a phone call.

FAQs – Unilock Construction in Cupertino

Can you install a Unilock paver driveway around a protected heritage tree in Cupertino?
Yes, and we do it regularly. Cupertino’s tree ordinance means heritage oaks and redwoods can’t be removed or heavily pruned without a permit, so we design paver driveways that route around the drip line and use permeable Unilock systems where the root zone needs water and air. You’ll need a tree protection plan approved by the city, and we prepare that as part of the permit package. Call (855) 901-7266 for a site assessment if you have a protected tree near your proposed layout.

Why are my Unilock Brussels Block pavers sinking near the garage after last winter?
Almost always, the base wasn’t engineered for Cupertino’s expansive clay. Winter rain saturates the soil, the clay swells, and when it dries in summer the ground shifts, leaving pavers uneven and water pooling where the driveway meets the garage slab. The fix is lifting the affected area, re-grading, and rebuilding the base to the correct depth with proper compaction. Patching the surface won’t stop it.

How much does a Unilock paver patio cost in Cupertino compared to concrete?
A Unilock paver patio in Cupertino typically runs $3,500 to $11,000 depending on size and base conditions, while concrete driveways fall in the $4,500 to $12,000 range. Pavers cost more upfront than a basic pour but tolerate clay movement far better, and individual units can be lifted and reset instead of cracking like a slab. Call (855) 901-7266 for an exact quote once we see your lot.

Do you need a permit for a Unilock retaining wall in Cupertino?
Most retaining walls over 3 feet require a permit in Cupertino, and any wall near a heritage tree or on a slope that affects drainage will trigger design review. We pull the permits, submit the engineering drawings, and coordinate with the city so you’re not chasing paperwork.

Can Unilock pavers be installed over existing concrete in Cupertino?
In some cases, yes, when the concrete slab is structurally sound and the added height doesn’t create step or drainage problems. But on Cupertino’s clay soils, a slab that’s already cracking will telegraph those cracks through the pavers, and we’ll recommend removing it and building a proper base instead. We’ll tell you which path makes sense after we see the existing concrete.
