Unilock Construction in Lompico, CA | Timberline Contractors
We install, repair, and rebuild Unilock paver driveways, patios, and segmental retaining walls throughout Lompico as a Lompico General Contractor. The one thing that makes our Unilock work here different is that we plan every project around steep canyon access, Santa Cruz County permitting, and CAL FIRE defensible-space requirements before a single block gets ordered. If you’re in the 95005 and researching Unilock for a driveway, patio, or wall rebuild, call (866) 253-5808 for a free on-site estimate.

We’ve built our reputation in the San Lorenzo Valley on Unilock sales & service done right: proper over-excavation, compacted base in lifts, geotextile where the grade demands it, and genuine Unilock block, caps, and edging where geometry and color match matter. Lompico’s terrain doesn’t forgive shortcuts, and neither do we.
Why Lompico Residents Choose Us for Unilock Service
Most contractors who say they “do pavers” have never set a Unilock Pisa2 wall on a 30% grade. We have. Our crews understand the engineering behind segmental retaining systems: the buried course, the leveling pad, the drain gravel behind the wall, the geogrid reinforcement, the positive drainage plane. On a Lompico slope, those details aren’t optional. They’re the difference between a wall that holds for decades and one that bulges after the first wet winter.
Nelson Fung leads our hardscape division with a background that matters: he learned construction formally at Los Angeles Trade-Technical College and spent years on residential and commercial builds across the LA basin before bringing that training to mountain terrain. He’ll tell you exactly where a cheaper base aggregate will cost you twice as much in three years, and where it won’t matter. That’s the kind of straight answer Lompico homeowners keep calling us for.
We’re licensed and insured, we pull the County permits, and we stand behind the work with a written workmanship warranty. No manufacturer authorization implied; we’re an independent Unilock installer, which means we answer to you, not a corporate dealer program.

Common Unilock Construction Problems We Solve in Lompico
- Bulging and stepped-out wall faces on steep grades. Unilock segmental wall blocks are engineered and sound. What fails is the base. When a leveling pad and drain gravel are under-built on a sloped canyon lot, the wall face bulges and courses step out after a wet winter. We rebuild these right: over-excavation, compacted base, geogrid where the height demands it, and a drain to daylight.
- Efflorescence and moss staining on Brussels Block and Pisa2 faces. Lompico’s deep shaded redwood and tanoak canopy keeps pavers and wall caps damp for months at a time. Mineral bloom and green film return unless the surface is sealed and runoff is redirected. We address the water path first, then treat and seal.
- Root heave and joint sand loss on paver fields. Where a paver driveway or patio meets a graded uphill cut, seasonal runoff sheets across the joints and washes out the polymeric sand. Roots from mature tanoaks push up from below. We excavate deeper, install geotextile where needed, and re-sand with a high-performance polymer once the drainage is corrected.
- Settlement and rutting on long private driveways. This is common on the steep access drives off Lompico Road where the original excavation was barely scratched in. The subgrade wasn’t removed, the base wasn’t compacted in lifts, and no geotextile was laid. The fix is a full rebuild, not patching.
- Weed intrusion at paver edges and transitions. Where a patio meets a cut slope or a driveway meets the road apron, weeds and moisture creep in. We install proper edge restraint, fix the drainage gradient, and use a joint stabilizer that holds up in Lompico’s damp, shaded conditions.
Unilock Service in Lompico: What Local Conditions Mean for Your Paver Project
Nearly every Lompico lot is a steep, unpaved or partially paved private drive, and unincorporated Santa Cruz County permitting plus CAL FIRE “very high” severity zone fire-hardening expectations mean a paver driveway or patio here is planned as an erosion-control and defensible-space surface, not just curb appeal. That’s the thing a generic Unilock page or a generic mountain-town page never tells you. In Lompico, your paver project will likely be reviewed by the County for drainage, slope stability, and vegetation clearance. It’s not a suburban patio job with different scenery; it’s a rural-mountain build with a different approval path and a different set of failure modes. Up off Lompico Road on a steep, shaded canyon lot, our crew rebuilt a heaved paver driveway where the original subgrade was barely scratched in. We over-excavated, laid geotextile and compacted base in lifts, set Unilock Brussels Block with a positive cross-slope and a drain to daylight, and the owner’s winter runoff now clears the drive instead of sheeting into the wall footing. The material had to come up in small loads because the delivery truck couldn’t make the last grade, so we staged block and base at the road and shuttled it up. That’s normal here, and it changes how you bid, schedule, and build.
Unilock Models & Products We Service in Lompico
We install and repair the full range of Unilock paver and wall systems, including Brussels Block, Pisa2, Beacon Hill, Tribeca, and the U-Cara wall system. We use genuine Unilock block, caps, and matching accessories where the system’s geometry and color match matter, and quality aftermarket base aggregate, geotextile, and polymeric joint sand where they outperform. We stock common Unilock replacement cap units and edge restraints for fast Unilock repair in Felton and Lompico turnaround, and we’ll order exact-color block for larger rebuilds. Our honest stance on repair vs. replace: a failed base or drainage plane means rebuild the base and reset the pavers. Patching a bulged wall or re-sanding a rutted drive just buys one more rainy season.

What drives cost on a Lompico Unilock job is access, excavation depth, and drainage. The block itself is predictable; it’s the site that varies. Here’s what we see across the San Lorenzo Valley:

FAQs – Unilock Construction in Lompico
Yes, when it’s built correctly. The key is over-excavating the subgrade, compacting base in lifts, adding geotextile where the soil wants to pump, and setting a positive cross-slope so water leaves the surface. On steep grades, we also consider permeable or drain-to-daylight details. Cheaping out on base depth on a Lompico slope is a guaranteed do-over in a few seasons. Call (866) 253-5808 if your drive is showing ruts or edge settlement.
The white is efflorescence; the green is moss and algae. Lompico’s shaded redwood/tanoak canopy keeps hardscape damp for months, and the mineral salts in the block wick to the surface. We fix the moisture path first (improve drainage, redirect runoff), then clean, treat, and seal. Sealing alone won’t solve it; the water source has to be addressed.
We stage materials at the road or the widest accessible point and shuttle up in small loads with a compact tracked loader. Full-size delivery trucks often can’t make the last grade or the tight switchback. This adds time and labor cost, but it’s baked into our Lompico estimates from the start. We don’t surprise you with it mid-project.
Often, yes. Lompico is unincorporated Santa Cruz County, and CAL FIRE “very high” severity zone rules may require defensible-space and vegetation-clearance considerations tied to hardscape. Drainage and slope-stability review is also common. We handle the permit process as part of the project scope, including the site plan and any required erosion-control measures.
In Lompico, on a slope, a bulging wall almost always means the base or drainage behind the wall failed. Re-stacking the face without fixing what’s underneath is cosmetic and temporary. We’ll assess the original leveling pad, drain gravel, and geogrid, then recommend either a targeted base repair or a full rebuild. We’ll tell you straight which one you actually need. Call (866) 253-5808 for an honest assessment.
