Unilock Construction in El Granada, CA | Milpitas Construction
We provide independent Unilock construction and repair across El Granada, from paver driveways to retaining walls. The thing that separates Unilock work here from anywhere else is drainage: our hillside lots move water fast, and a paver installation that ignores that fails within two winters. That’s the problem we solve before it starts. Call (877) 752-4194 for a free estimate on your El Granada project.
Why El Granada Residents Choose Us for Unilock Service
Ken Stafford, our owner, has spent two-plus decades on Bay Area job sites where the soil moves and the coastal air eats metal. He grew up near the Milpitas BART station, trained in construction technology at Evergreen Valley College, and built his reputation on work that holds up to seismic shifts and salt air without callbacks. That background matters for Unilock work in El Granada because the conditions here punish shortcuts. We’ve installed Brussels Block, Beacon Hill, Copthorne, and Estate Wall systems on sloped coastal lots from Princeton-by-the-Sea to the hills above Alameda Avenue, and we spec each project for what’s actually under and around the pavers. Our crews handle base prep, edge restraints, and drainage the way the manufacturer intends, and we bring Unilock sales & service experience to every build.

Common Unilock Construction Problems We Solve in El Granada
- Chalky, white residue on pavers (efflorescence). The salt-laden onshore wind off the Pacific into El Granada accelerates mineral migration through Unilock pavers, especially on west-facing patios and driveways. That chalky bloom isn’t a defect. It’s the coastal environment pulling salts to the surface, and cleaning it without sealing the right way just brings it back.
- Settled or heaved paver sections near the garage or foundation. Winter runoff coming off El Granada hillsides scours the base rock out from under pavers. We regularly find driveways where the first eight feet near the garage has dropped two inches because water found a path under the edge restraint and washed the fines out.
- Offset or leaning retaining wall blocks. Unilock Estate Wall and other segmental wall systems rely on proper drainage behind the wall. On El Granada slopes, hillside groundwater builds up behind walls and pushes them out of alignment. We see lateral shifting where builders skipped the drain tile or used fabric that’s long clogged.
- Weeds and ants working through paver joints. The persistent marine-layer moisture in El Granada keeps polymeric sand from fully curing. Joints stay soft, then erode in the first real rain, and within a season you’ve got weeds and ant colonies where the sand used to be.
- Paver edges creeping outward. Salt air corrodes steel and aluminum edge restraints within a few years in El Granada. Once the restraint lets go, the outer course of pavers starts walking toward the fence line, and the whole field of pavers loses tension.
Unilock Service in El Granada: What Local Conditions Mean for Your Equipment
Here’s the thing about building with Unilock pavers and walls in El Granada that inland contractors don’t plan for: the hillside lots funnel winter storm runoff directly toward lower structures. We’re not talking about a puddle. We’re talking about a concentrated sheet of water moving downhill fast enough to move base rock. That’s why nearly every Unilock paver driveway or patio in El Granada needs a subsurface drainage system – a French drain, a channel drain, or both – before the base rock goes down. Skip that step and you’re building on a sponge. On a steep lot off Alameda Avenue, our crew tore out a heaved Brussels Block patio where runoff had scoured the base. We regraded the slope, added a channel drain tied to a dry well, and reinstalled the pavers on a compacted, geotextile-reinforced base with fresh polymeric sand. That patio now sheds winter runoff instead of pooling it against the foundation. Build it right the first time – the Bay Area doesn’t give you a free pass on shortcuts.
Unilock Models & Products We Service in El Granada
We install and repair the full Unilock paver and wall lineup you’ll find in El Granada: Brussels Block for driveways and patios, Beacon Hill and Copthorne for their blend of old-world texture and coastal durability, and Estate Wall for sloped lots that need real retention. When it comes to parts, we use Unilock OEM components for structural wall systems and edge restraints because the geometry matters. For polymeric sands and sealers, we choose aftermarket products formulated specifically for coastal conditions, since the marine layer here demands a different cure profile than inland installs. We keep common paver sizes, edge restraints, and compatible sand on hand for fast El Granada turnaround without waiting on distributor shipments.

AfterUnilock Service Pricing in El Granada
Pricing for Unilock work in El Granada depends on three things: slope, drainage, and access. A flat patio that needs no drain work is simple. A hillside driveway that needs a channel drain, a dry well, and reinforced base is a different job entirely. Here are the ranges we work within:
| Project | Typical El Granada Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Home Addition | $45,000 – $130,000 |
Every estimate includes a walk of the actual site with a level, a look at where the water moves, and a written scope with the paver line named, the base depth specified, and the drainage plan drawn out. No change orders because the ground shifted. Call (877) 752-4194 to schedule yours.

FAQs – Unilock Construction in El Granada
That chalky white residue is efflorescence, and in El Granada it’s accelerated by the salt-laden onshore wind that pushes minerals through the paver surface. West-facing patios get hit hardest. Cleaning is straightforward, but sealing with the wrong product traps the salts and makes it worse. We spec breathable sealers made for coastal pavers. Call (877) 752-4194 and we’ll tell you whether yours can be cleaned or needs a targeted rebuild.
Yes, if it’s built with proper drainage behind it. A Unilock Estate Wall system is structurally capable, but the drain tile, filter fabric, and gravel backfill do the real work in El Granada’s wet winters. We’ve repaired walls where the blocks were fine but the drainage was absent, and the wall was slowly rotating forward. The fix is drainage, not new blocks.
El Granada’s marine layer keeps joints damp longer, so we use polymeric sands formulated for high-humidity environments and schedule installation when we have a clear window for the sand to cure. We also compact joints in lifts rather than laying all the sand at once. If your existing sand is eroding, we can re-sand and stabilize before the next winter.
Almost always yes in El Granada. Runoff from the hillside finds its way under the driveway, washes out the fines, and the pavers drop. It’s not a paver problem. It’s a base and drainage problem. We’d pull the settled section, inspect what’s underneath, add drainage if it’s missing, and rebuild on compacted base. Call (877) 752-4194 for a look.
They need earlier sealing and more frequent joint checks than inland installs. Salt air accelerates surface wear and edge restraint corrosion. A yearly walk of your patio or driveway catches problems before they become rebuilds. We offer maintenance checks for Unilock installations throughout the 94018 ZIP code and provide Montara Unilock service as well.
