Unilock Construction in Ladera, CA | Ashford Contractors
We install and repair Unilock paver driveways, patios, and retaining walls across Ladera General Contractor‘s hillside lots. The one thing that makes our Unilock work here different: we plan every install around San Mateo County’s WUI fire-hardening rules and the slope drainage reality of 94028, not just the paver pattern. Call (877) 752-3868 for a free estimate on your Unilock hardscape.
Ashford Contractors is an independent Unilock service provider. We are not authorized, sponsored, or endorsed by Unilock. What we are is a full-scope general contractor that has spent years putting Unilock pavers and walls on steep, wooded parcels most flat-lot installers would walk away from. Unilock sales & service is part of what we do, alongside roofing, siding, windows, and everything else Ladera homeowners need from the roofline to the foundation.
Why Ladera Residents Choose Us for Unilock Service
Glen Mossier, our owner, grew up in San Mateo County and cut his teeth on the kind of hillside construction that defines Ladera. He trained in construction technology at Skyline College, learning framing and materials science before he ever touched a paver. That background matters when your driveway has to hold a 15% grade and still shed stormwater correctly. We read the slope first, then build the hardscape to work with it. Build it right the first time, and you won’t be rebuilding it in ten years.
Ladera is a small, unincorporated pocket west of Menlo Park. Nearly every Job we do here involves county permitting, not a city building department, and that changes how Unilock work gets approved and inspected. We know those county codes. We also know the narrow roads, the tree canopies that keep pavers damp, and the fire-access setbacks that dictate where hardscape can and can’t go. We’re a local Ladera service area contractor, not a crew driving in from the East Bay hoping the access road is wide enough.

Common Unilock Construction Problems We Solve in Ladera
- Joint sand washout and paver shifting on steep driveways after atmospheric-river storms. When surface water concentrates at the curb or a low spot in the grade, the sand between Brussels Block pavers washes out and stones start to drift. We rebuild with proper base compaction and re-sweep Unilock’s specified joint sand. The fix isn’t more sand on top. It’s fixing where the water goes first.
- Retaining wall block movement or bulging on hillside lots. U-Cara and Beacon Hill walls fail when they’re built without geogrid and drainage pipe behind the block. We see this regularly on Ladera slopes where a previous contractor treated a segmental wall like a garden border. We excavate, place geogrid correctly, install a drainage aggregate column, and reset the wall so it actually holds the grade.
- Efflorescence and surface staining on shaded, treed parcels. Brussels Block and other cementitious pavers develop white mineral bloom and dark organic staining when they sit under dense oak and redwood canopy that never fully dries. We clean with appropriate efflorescence removers and can apply a breathable paver sealer after cleaning so the surface resists re-staining.
- Edge restraint failures at driveway aprons. On Ladera’s narrow winding access roads, every vehicle turn loads the outer edge of the paver field. When plastic edge restraint was skipped or driven into uncompacted base, the edge row pops loose. We use Unilock’s compatible edge restraints and drive them into properly compacted aggregate.
- Sheet-flow drainage channeled toward garages and foundations. A badly graded paver surface doesn’t just look wrong. It sends storm runoff straight at your structure. We re-grade to sheet-flow away from the house and garage, then lay the pavers to that corrected grade. This is one of the most common failure modes we fix on Ladera lots.
Unilock Service in Ladera: What Local Conditions Mean for Your Equipment
Ladera sits inside San Mateo County’s wildland-urban interface, which means your Unilock hardscape often has a second job: fire-hardening. Noncombustible paver aprons, wall caps, and patio edges create defensible space around the home and can help satisfy WUI/chapter-7A-style fire-resistive requirements the county applies here. It’s a different conversation than someone needing Unilock service in West Menlo Park would ever have. It’s also why we plan material deliveries and staging around narrow, winding hillside roads that county fire-access rules govern. A flatbed that can stage on a wide suburban street may not even make the turn onto a Ladera access road. We’ve done enough deliveries off La Mesa Drive and similar routes to know which truck sizes work, and we sequence material drops so nothing sits blocking a fire lane overnight. That’s the difference between a paver install planned for Ladera and one planned for anywhere else in the county.
On a steep, treed parcel off La Mesa Drive, our crew replaced a heaved Brussels Block driveway that had been laid over an inadequate base and was channeling storm runoff toward the garage. We re-graded to sheet-flow away from the structure, rebuilt the base with proper compaction and drainage, and reset the pavers with new Unilock edge restraint. The homeowner now has a driveway that meets the slope, not fights it.
Unilock Models & Products We Service in Ladera
We work with the full range of Unilock lines installed across 94028. Brussels Block is the workhorse here: tumbled, forgiving, and suited to driveways and patios that see real use. Beacon Hill is the go-to for homeowners who want a smoother, more transitional paver and wall look. Elegance gives us the large-format, smooth paver option for modern hardscape designs, and U-Cara is our standard choice for segmental retaining walls on grade changes. On repairs, we use Unilock’s own compatible cap units, edge restraints, and specified joint sand. For base and drainage layers, we source quality aftermarket materials where they outperform. We’ll also give you the honest answer on repair versus replacement. A wall with a couple of shifted blocks can usually be reset. A wall with failing geogrid cannot.

What drives the cost on a Ladera job: slope, access, base depth, and the amount of regrading needed before a single paver goes down. A flat 400-square-foot patio off a wide driveway costs the bottom of the range. A steep, 1,200-square-foot driveway with poor compaction, bad drainage, and tight truck access costs toward the top. Your free estimate includes a site walk, slope and drainage review, and a written line-item quote. Call (877) 752-3868 to schedule yours.

FAQs – Unilock Construction in Ladera
Yes. Ladera slopes demand a deeper, properly compacted aggregate base and careful subgrade drainage. On flat lots, a 4-to-6-inch base often works. On a 10% grade with heavy clay, we typically go deeper, add geotextile fabric, and make sure water moves through and away from the base. Skip that and the pavers shift within two or three storm seasons. Call (877) 752-3868 and we’ll tell you exactly what your site needs.
Yes, when they’re built correctly. U-Cara and Beacon Hill walls hold serious grade. The failure we see in Ladera is almost always a missing or poorly installed geogrid and drainage column behind the block. Built to spec with proper compaction and drainage, a Unilock segmental wall handles Ladera’s hillside grades for decades. We’ll assess your wall and tell you if it needs resetting or full rebuild.
A noncombustible paver driveway and paver patio edges can function as part of your defensible space plan. Pavers don’t burn, which helps interrupt ground-level fire spread near the structure. We can’t say a paver driveway alone satisfies any specific county WUI requirement, but in Ladera’s wildland-urban interface, it’s part of a strategy that includes vegetation clearance, ember-resistant vents, and noncombustible zones. We coordinate with what the county is already asking you to do.
We sequence material drops with smaller trucks where access is tight, and we stage material in phases so nothing blocks fire access or your neighbors’ driveways. On narrow hillside roads like the ones off La Mesa Drive, we often have to split a delivery across two or three trips. It’s slower, but it keeps the road passable. This is standard practice for us in Ladera, not an afterthought.
Within one to two weeks. A shifted paver or washed-out joint isn’t just cosmetic. Once water gets under the base, freeze-thaw cycles and erosion accelerate, and you’ll eventually have a bigger repair bill. Call (877) 752-3868 after a storm and we’ll schedule a site check. Estimates are free, and we’ll tell you whether it’s a $400 reset or a $14,000 rebuild, honestly.
