Unilock Construction in Las Lomas, CA | San Mateo Construction
We install, repair, and re-level Unilock paver driveways, patios, and walls throughout Las Lomas, CA. What sets our work apart here specifically is that we plan every job around the unincorporated Pajaro Valley reality: Monterey County review, sloped agricultural parcels, and damp coastal air that never fully dries from October through March. If you’re pricing a Unilock project in Las Lomas, call (855) 901-7266 and we’ll give you a straight assessment based on your lot, your drainage, and what actually holds up out here.
We’re an independent contractor working with Unilock products, not a manufacturer-authorized service arm. Noel Carrington and our crew have handled Unilock installs across Monterey County for years, and we’ve learned what works on these particular lots by doing it. That means compacted bases, drainage corrections, and edge restraints installed to survive actual farm runoff, not just a showroom floor. San Mateo Construction covers Las Lomas and the surrounding Pajaro Valley as a true single-source contractor: we handle hardscape, additions, roofing, windows, and interior work under one contract. If your Unilock project also needs grading or a retaining wall tied to a house addition, one crew can own the whole thing.
Why Las Lomas Residents Choose Us for Unilock Service
The short answer: we’ve already solved the problems your property is going to throw at us. Las Lomas lots are not flat suburban yards. Many sit on slopes above the valley floor with clay soils, farm drainage crossing through, and well heads or septic lines you can’t just pave around with guesswork. Our team has replaced Unilock pavers off Las Lomas Drive where winter runoff had undermined the joint sand, and we’ve built paver roadways that hold up to equipment trailers coming in and out of active agricultural parcels.
Noel grew up in San Mateo County pouring concrete with his father and spent three decades on residential and light commercial work before this. He still approaches every Las Lomas job the same way he’d want it done on his own block: call it straight, spec it right, and don’t leave a drainage problem hiding under a good-looking paver. That’s why we lean on OEM edge restraints and polymeric joint sands from Unilock, but we’ll also specify aftermarket drainage products when the site calls for something heavier than the manufacturer’s standard lineup. We’re not here to sell you the most expensive version of the project, we’re here to make one that survives a wet Pajaro Valley winter.

Common Unilock Construction Problems We Solve in Las Lomas
We see the same issues repeat on Las Lomas properties, and most of them trace back to two things: moisture and slopes. Here’s what we fix most often:
- Efflorescence on Brussels Block and concrete pavers: That white, chalky film appears when soluble salts rise through the paver surface as moisture evaporates. In Las Lomas, the coastal fog and cool, damp winters keep pavers wet for weeks at a time, so efflorescence blooms worse here than it does inland. We clean it properly and adjust the base and drainage so it stays gone.
- Settling and shifting pavers on sloped lots: Many Las Lomas homes sit on graded agricultural parcels where the original compaction wasn’t designed for a vehicle-loaded paver surface. We re-grade, compact properly, and rebuild the section so it doesn’t sink again after the first heavy rain.
- Joint sand washout along driveway edges: When winter runoff crosses from a neighboring farm field, it strips the polymeric sand and eventually undermines the edge restraints. We rebuild the edge with concrete restraints and re-sand with product rated for wet conditions.
- Frost heave and surface spalling on older installs: Not every paver specified for a mild climate survives the wet-freeze cycles the Pajaro Valley gets in cold snaps. Where older Unilock installations were under-specified, we tear out and replace with the right product for a damp microclimate.
- Drainage failures around wells and septic lines: In Las Lomas, a paver project often has to work around well heads, septic tanks, and leach field setbacks. We’ve corrected bad gradings that sent water toward the well house, and we design new work to keep runoff moving away from what matters.
Unilock Service in Las Lomas: What Local Conditions Mean for Your Equipment
Here’s the thing most advice misses: Las Lomas is unincorporated Monterey County, so any Unilock paver project that involves grading, drainage improvements, or a driveway adjoining a county-maintained access point goes through county building review. You don’t get the faster city permit process a Watsonville job inside city limits would get. What you get instead is a plan checker looking carefully at your slope, your runoff path, and whether your new hardscape pushes water onto an adjacent agricultural parcel. That extra scrutiny is real, and it’s shaped by the fact that Las Lomas sits in the Pajaro Valley with working farms all around it.
For Unilock owners, this means the base and drainage work is not optional, it’s the difference between a paver surface that lasts 20 years and one that heaves and washes out after two. We’ve sat through Monterey County grading reviews for projects off Las Lomas Drive, and we know what the reviewers flag. We also know that on most rural lots out here, you need to preserve farm-equipment access: a truck, a trailer, sometimes a tractor. A paver driveway designed only for a passenger car will fail at the first harvest-season turn-in. We plan for that.
Unilock Models & Products We Service in Las Lomas
We install and repair the full Unilock range most common on Pajaro Valley properties. That includes Brussels Block for driveways and patios where you want a classic tumbled look, Beacon Hill for a tighter, more dimensional surface, Estate Wall blocks for retaining walls and low garden walls, and Lineo Stone where a longer, more linear profile fits the house. Each line has different joint widths, surface performance, and base recommendations, and we match them to what your Las Lomas lot actually demands.
For repairs, we use Unilock’s OEM edge restraints and polymeric joint sands where the manufacturer’s spec is the right call, and we stock enough common product locally to turn around most Las Lomas repair jobs quickly. When an aftermarket drainage product outperforms the OEM option for a specific site, we’ll say so and use it. The goal is always a surface that stays stable and drains right, not brand loyalty for its own sake. For broader background on our Unilock work, see our Unilock sales & service page.

FAQs – Unilock Construction in Las Lomas
Yes, but only if the base and drainage are engineered for the slope before the first paver goes down. We regrade where needed, compact to spec, and add drainage so runoff moves away from wells, septic areas, and neighboring parcels. A poorly drained slope will eventually heave and shift the pavers. Call (855) 901-7266 and we’ll walk your specific lot before you commit to anything.
Las Lomas jobs go through county building review, which often adds grading and drainage scrutiny beyond what a city permit would require, especially on sloped or agricultural parcels near areas needing Unilock repair in Watsonville. We factor that into the timeline and the plan from day one, and we’ve handled enough of these reviews to know what gets flagged. We’ll prepare the permit package so it doesn’t stall your project.
That’s efflorescence, a mineral deposit that rises through the paver surface as moisture evaporates. It’s common on Brussels Block and other concrete pavers in Las Lomas because the coastal fog keeps surfaces damp for long stretches, slowing evaporation and leaving more salts visible—something we also address with Amesti Unilock service. We clean it correctly and can adjust the base or drainage to reduce how much moisture drives it. Call (855) 901-7266 for an assessment.
Yes, with the right base and joint specification. A standard residential base will not hold up under repeated truck and trailer loads, especially on a Las Lomas lot where the soil never truly dries. We build to handle the load you actually run, not just a car. If you tell us what equipment crosses the driveway, we’ll spec it correctly.
They can heave if the base wasn’t compacted or drained properly, and older installs that weren’t specified for wet-freeze cycles sometimes spall. New work installed to manufacturer spec with the right drainage holds, just like our Unilock repair in Corralitos. We re-level and re-sand where repair makes sense, and we’ll be honest when the right call is replacement. Estimates are free, call (855) 901-7266 for an exact quote.
