Unilock Construction in Woodside, CA | Seaside Contractors
We provide independent Unilock paver, wall, and hardscape construction across Woodside, CA. The one thing that makes our Unilock work here different is that we plan every project around the town’s private wells, septic systems, and clay-heavy soils before a single paver gets set. If you’re planning a Unilock driveway, patio, or retaining wall in Woodside, call Seaside Contractors at (833) 589-8103 for a free estimate.
We’ve installed Unilock systems across the Santa Cruz Mountains transition every season, so we know how their products actually perform here, not just how they look in a showroom. We’re an independent contractor, not authorized or endorsed by Unilock. We simply specify and install their products because they hold up when base and drainage are built correctly. From Unilock sales & service to full hardscape builds, we’re the team Woodside homeowners call when they want the job done once.
Why Woodside Residents Choose Us for Unilock Service
Unilock makes a serious paver. But a paver is only as good as the base underneath it, and Woodside’s soil doesn’t forgive shortcuts. We know the difference between a Brussels Block driveway that stays flat through a wet winter and one that starts migrating by March, because we’ve built both, and we’ve repaired the ones other contractors got wrong.
Glen Sorrento, our owner, grew up in Foster City watching lagoon-side homes get built and rebuilt, then studied building construction technology at College of San Mateo before spending two-plus decades working through nearly every project type the Peninsula throws at a contractor. That background means he can look at a Unilock spec sheet and a Woodside grading plan in the same afternoon and give you a straight answer on both. We use Unilock’s own edge restraints, joint sand, and wall components because mixing aftermarket pieces is where failures start. For existing hardscape, we repair and re-set sound units where the base is intact rather than pushing a full tear-out. One contractor, every trade, serving all of Woodside service area.

Common Unilock Construction Problems We Solve in Woodside
- Edge restraint failure and paver migration on driveways. When the base isn’t excavated deep enough for Woodside’s clay-heavy soils and winter saturation, the edges spread and the field starts to wander. We dig deeper than the generic spec and set Unilock edge restraints with real anchorage.
- Sand-joint washout and rutting on sloped driveways and patios. The rain-shadow transition lots here shed water fast when runoff isn’t graded away from the house. We re-grade the subgrade so water moves where it should, then use polymer joint sand that stays put.
- Efflorescence and surface staining on Brussels Block and Beacon Hill units. When water ponds against the base or wicks up from poorly drained subgrade, white mineral deposits bloom on the paver face. The fix is drainage first, cleaning second, not just sealing over the symptom.
- Wall unit settlement and bulging on Estate Wall and Pisa2 retaining walls. Built without proper geogrid and drainage aggregate behind the wall against expansive clay, these walls lean and bulge within a few seasons. We rebuild them with the drainage they should have had from day one.
- Permeable paver systems, Thornbury and Copthorne, that stop draining. When the open-graded base gets clogged with fine Woodside clay or the underlying soil wasn’t tested for infiltration, the system backs up. We test the subgrade before we ever spec a permeable system here.
Unilock Service in Woodside: What Local Conditions Mean for Your Pavers
Here’s what actually decides whether a Unilock driveway or wall survives in Woodside. Because much of the town is on private wells and septic, a hardscape or addition project that reworks grading near a leach field or well head can force a percolation test and well-yield review before work starts. That’s a permitting sequence that stalls projects before the first framing nail or paver is driven. So we map septic and well locations onto the Unilock layout before we stake a single paver line. On a Woodside Home Remodeling project near Woodside Road, the owner wanted a Unilock Brussels Block driveway tied into a new detached garage, but the existing slope shed winter rain straight toward the septic field. We re-graded the subgrade, dug a deeper compacted base than the original spec, installed a perforated drain along the uphill edge, and set the Brussels Block with Unilock edge restraints and polymer joint sand. The driveway has stayed flat through two wet winters. That’s the difference between planning around Woodside’s constraints and finding out about them later.
Unilock Models & Products We Service in Woodside
We install and service the Unilock lines that make sense for Woodside’s lots and architecture. Brussels Block pavers are our standard for driveways and walkways where a classic tumbled look fits the town’s ranch homes and newer estates. Beacon Hill flagstone-style pavers work well for patios and pool surrounds where homeowners want a more organic surface. For retaining walls, we use Estate Wall units, Pisa2 and Olde Quarry, with geogrid and drainage aggregate specified to the slope. Thornbury and Copthorne permeable systems get used where a project needs to manage runoff without sending it toward a septic field or neighboring structure. We stock the common edge restraints, joint sands, and wall components locally so Woodside turnarounds don’t wait on a freight depot. We also offer Unilock service in San Carlos with the same local inventory approach. When an existing hardscape needs repair, we re-set sound units and match Unilock’s own components rather than substituting aftermarket parts that never quite fit.

FAQs – Unilock Construction in Woodside
Yes, and we do it regularly, but the septic and well locations have to be mapped onto the paver layout before any grading happens. Adding or reworking hardscape near a leach field or well head can trigger a percolation test and well-yield review through Woodside’s permitting process. We work with that sequence, not around it. Call (833) 589-8103 and we’ll walk you through what applies to your specific lot.
Because Woodside sits in the Santa Cruz Mountains rain shadow transition with clay-heavy soils that expand when saturated and shrink when dry, plus real winter rainfall. A shallow base that works in a flat valley lot fails here within a season or two. We excavate deeper than generic specs, compact in lifts, and install drainage that moves water away from the paver base before it can undermine anything.
Correctly installed pavers and walls can actually improve defensible space by replacing combustible ground cover and creating a clean perimeter, but grading and wall placement have to work with Chapter 7A fire-resistant construction requirements and the town’s defensible-space clearing rules. We coordinate that with the rest of the project so your hardscape supports fire safety rather than complicating it.
For most sloped Woodside lots, we use Unilock Estate Wall units, Pisa2 or Olde Quarry, set with geogrid reinforcement and clean drainage aggregate behind the wall. On expansive clay, that aggregate layer and proper weep drainage are not optional; they’re what keep a two-foot wall from bulging into a four-foot problem.
Often yes. Woodside’s design-review process, lot-size zoning, and the well/septic review sequence can all apply depending on the scope and location of the hardscape or addition. We pull the permits and manage the reviews so you don’t have to steer them. Call (833) 589-8103 and we’ll tell you what your project triggers.
