Unilock Construction in Hillsborough, CA | Copperleaf Contractors
We’re Copperleaf Contractors, and we install, repair, and re-set Unilock paver driveways, patios, and retaining walls across Hillsborough. The work here is different from anywhere else on the Peninsula because Hillsborough’s hillside estates demand geotechnical review and arborist coordination before excavation starts, which means the base under your pavers matters as much as the pavers themselves. Call (833) 589-8173 for a free site assessment and written estimate.
Why Hillsborough Residents Choose Us for Unilock Service
We’ve laid, cut, and re-set Unilock profiles on sloped, tree-rooted Hillsborough lots long enough to know where the material excels and where local soils and grades work against it. Noel Cavanaugh, our owner and general contractor, grew up in Sharp Park dealing with coastal moisture and studied construction technology at Skyline College before spending two decades on residential projects up and down the San Mateo County coast, including Unilock service in San Mateo. That background matters when you’re evaluating a paver driveway on a steep Hillsborough street where winter runoff concentrates at the apron. We know the site before we touch it, and we bring genuine Unilock units and matching OEM color lots so repairs blend instead of standing out.

Common Unilock Construction Problems We Solve in Hillsborough
These are the failure modes we see repeatedly on Hillsborough estates:
- Polymeric joint sand washing out on steep driveways. Hillsborough’s wet winters send sheet-flow runoff down sloped aprons and concentrated channels. Sand erodes, pavers loosen, weeds move in. We re-grade pitch and re-sand with proper compaction.
- Edge restraint failure at the toe of sloped aprons. Base compaction that works in flat neighborhoods fails here when expansive clay and tree-root voids shift under the weight of vehicles. We install upgraded edge restraint and re-compact the base to Hillsborough’s grade realities.
- Efflorescence and staining on light-colored Brussels Block. Where drainage pitches toward the house or water ponds beneath the pavers, white mineral deposits and dark stains appear. Fixing this means fixing the drainage, not just the surface.
- U-Cara retaining wall creep on hillside terraces. Walls bulge and shift when geogrid and drain rock were omitted or under-specified behind the block. We rebuild properly, with drainage behind every course.
- Base settle on older installations. Heritage oak roots decay and create voids over time. We re-lay the base when patching joints repeatedly would cost more than doing the job once, correctly.
Unilock Service in Hillsborough: What Local Conditions Mean for Your Equipment
Hillsborough’s hillside remodels routinely require a geotechnical report and arborist coordination before excavation, so a paver driveway or patio install here isn’t just surface work. Base design and root-zone protection around heritage oaks have to be settled before a single paver comes off the pallet. On streets off Crystal Springs and Ralston, we’ve seen contractors skip this step and pay for it within two winters. The mild Mediterranean climate with wet winters and dry summers means drainage and erosion control are the difference between a drive that holds and one that creeps. We coordinate with the town’s Planning Department requirements and arborists when we need to, because an install that ignores tree roots or slope stability fails faster in Hillsborough than almost anywhere else on the Peninsula.
On a steep estate drive off a wooded hillside street, our crew re-set a Brussels Block driveway where winter runoff had scoured the joint sand and undermined the edge restraint at the apron. We pulled and palletized the existing units, re-graded the base with proper compaction and pitch away from the garage, installed new edge restraint and geogrid, then re-laid the pavers on matching Unilock color lots so the repair blended with the field. That’s the kind of job you don’t learn from a catalog, you learn from doing it here.
Unilock Models & Products We Service in Hillsborough
We work with the full Unilock line that Hillsborough homeowners actually use. Brussels Block and the Brussels Dimensional System for driveways. Beacon Hill Flagstone for patios and walkways. U-Cara from the Urban Structured line for retaining walls and terraces. Town Hall and Copthorne for permeable, clay-brick style installations. For repairs, we source genuine Unilock units and matching OEM color lots so patches lock to the existing system and blend with the field. For edge restraint and geogrid, we use quality aftermarket products where they outperform. On older, settling installations we tell owners honestly when re-laying the base is cheaper long-term than repeatedly patching joints. As an independent contractor, we’re not tied to one supplier’s markup, so we match the material to the job. Choose the material, not the markup. Learn more about our Unilock sales & service.

FAQs – Unilock Construction in Hillsborough
No. We’re an independent Unilock service provider, not manufacturer-affiliated or authorized. That independence means we’re not pushed toward any single product, and we can be honest about what’s worth spending on and what isn’t. We install and repair Unilock pavers and retaining-wall systems across the Peninsula — from Unilock in Burlingame to Hillsborough — because they perform, not because we have to sell them.
Winter rain is the biggest threat to paver work in Hillsborough, so we re-grade the base with pitch away from structures before laying any units, use proper joint sand, and install edge restraint that holds under sheet-flow runoff. The goal is water moving off the surface and away from the house, not pooling under pavers. Call (833) 589-8173 for an exact quote, estimates are free.
