If you’ve got a settling paver driveway, a patio that’s losing joint sand, or a retaining wall starting to lean after a wet winter, you’re in the right place. We work extensively with Unilock sales & service products across the Peninsula, and we know which systems hold up on Portola Valley’s steep, oak-wooded slopes and which ones fight the terrain.

Why Portola Valley Residents Choose Us for Unilock Service

Most paving crews can lay blocks in a straight line. The difference shows up when the grade pitches hard, when drainage from a seasonal creek surges across an apron, or when Cal Fire’s vegetation rules say you can’t touch that oak’s root zone. That’s the work we do every week in Portola Valley service area homes.

Nate Burrell grew up watching crews frame up half of Paradise Valley in Morgan Hill, and he trained in construction technology at Gavilan College before spending two decades on job sites throughout South Santa Clara County. What he drilled into our crew is simple: do it once, do it right, everything else is just a future repair bill. On Unilock work, that means proper base compaction on clay, edge restraints that don’t float after one winter, and joint sand that survives fog and runoff. We’re a licensed general contractor, insured and bonded, and we use genuine Unilock-manufactured units for repairs so color and dimensional profiles match your existing field.

We’re an independent contractor. Not authorized or sponsored by Unilock. That’s actually an advantage, because we recommend what we’ve seen perform in Portola Valley rather than what a manufacturer’s rep wants pushed.

Common Unilock Construction Problems We Solve in Portola Valley

• Edge restraint failure on steep driveway aprons. Portola Valley driveways pitch harder than almost anywhere else in San Mateo County. When fall and winter rain concentrates runoff across an apron, plastic edge restraints without proper spike depth start to creep. Pavers migrate, gaps open, and the whole field shifts downhill. We reset restraints with deeper anchoring and re-grade the base so water moves around the field, not through it.
• Settling and rutting over native clay. The valley’s soil is heavy clay that expands when wet and shrinks when dry. If the base course was compacted too shallow, or if a contractor skipped a geotextile separator, you’ll get ruts where vehicles load the surface. We see this most on narrow private lanes where delivery trucks and fire equipment travel.
• Efflorescence and joint-sand washout on west-facing patios. Fog sits in Portola Valley longer than most people expect, especially on west-facing exposures. Damp surfaces slow evaporation, pulling mineral salts up through pavers as white efflorescence. That same moisture cycle breaks down polymeric joint sand faster. We clean, re-sand, and seal where appropriate.
• Paver loosening around heritage-oak root zones. When tree-protection plans limit excavation near mature oaks, the typical compaction specs go out the window. Roots grow, lift pavers, and crack the field. We handle paver layouts that accommodate root movement without committing arborist-review violations.
• Joint-sand loss where hillside runoff crosses the hardscape. Late summer thunderstorms and early season rains send water down Portola Valley’s hillsides fast. Unprotected paver joints wash out, leaving blocks to chatter loose. We re-sand with polymeric material rated for slope drainage and install drainage swales or channel drains where the water wants to go.

Unilock Service in Portola Valley: What Local Conditions Mean for Your Equipment

Here’s something a generic Unilock page won’t tell you. Because Portola Valley’s heritage-oak protection plans and narrow private lanes often block standard delivery trucks, Unilock paver pallets frequently have to be shuttled or staged off-site before a driveway or patio can be laid. A full semi with 20 pallets of Brussels Block simply cannot back up a private road with a 12-foot width and a root-protection fence on both sides. So we scope delivery access into the job before the first base course goes down. That means walking your lane with a tape measure, checking overhead clearance, confirming whether a smaller flatbed can make the turn, and sometimes staging product on a neighbor’s flat section with written permission. If we skip this step, your project stalls on day one with a truckload of pavers sitting on the county road. This is baked into our Portola Valley estimates, not added as a change order later.

Unilock Models & Products We Service in Portola Valley

We install, repair, and re-sand the full Unilock line most common on Peninsula properties. Brussels Block is the workhorse for driveways because the 60mm and 80mm options handle vehicle loads. Beacon Hill works well for paths and patios where a more tailored look is wanted. The Brussels Dimensional System gives clean, modular lines on contemporary Portola Valley rebuilds, and we also offer Stanford Unilock service nearby. Seneca Valley retaining wall blocks hold slopes and terraces. Eco-Priora permeable pavers meet stormwater requirements where driveway runoff rules are strict.

For repairs, including our Ladera Unilock service, we use genuine Unilock-manufactured units so color and dimension match the existing field. We keep base, bedding, and polymeric joint sand supplied from aftermarket sources suited to Portola Valley’s drainage and fire-defensible requirements. If your paver field is 80% sound, we repair and re-sand rather than push a tear-out. If the base is failed across a slope, we’ll tell you replacement is the honest call.

On a wooded lane off Los Trancos Road in an area where we also provide Unilock in Los Altos Hills, a homeowner’s Brussels Block paver driveway had settled and shifted where runoff from the hillside crossed the apron. Our crew found shallow base over clay under the migrated field. We reset the edge restraints, re-compacted and re-graded the base for drainage, laid new Brussels Block units to match, and re-sanded with polymeric joint sand. Pallets were shuttled up the narrow private drive on a smaller truck per the oak-protection access plan. That’s what proper Unilock work in Portola Valley looks like.
