Unilock Construction in Interlaken, CA | San Mateo Construction
Unilock paver work in Interlaken comes down to one thing most contractors miss: the base. We install and repair Unilock hardscape systems across the Pajaro Valley flatlands as an Interlaken General Contractor, not a manufacturer dealer. That means we pick the specific Unilock series that holds up on a low, flood-prone Interlaken lot instead of pushing whatever’s on the truck. If you’re pricing a paver driveway, patio, or replacement in ZIP 95019, call (855) 901-7266 for a straight answer and a free estimate.
Why Interlaken Residents Choose Us for Unilock Service
Noel Carrington grew up a few blocks from Coyote Point in San Mateo, pouring concrete footings with his father on weekends. That early work turned into three decades of residential and light commercial jobs across San Mateo County, and it shaped how we approach Unilock work in Interlaken: obsess over what’s under the paver, not just the paver itself.
We carry Unilock sales & service experience across every major paver line, and we know which ones perform on the Pajaro Valley floor. Brussels Block handles tight radii on older Interlaken properties. Beacon Hill Flagstone gives you that irregular, settled-in look without sacrificing edge strength. We stock genuine Unilock pavers, compatible OEM edge restraints, and polymeric sand locally, so a paver repair in Interlaken doesn’t wait on a freight shipment from the Midwest.
- Independent, not manufacturer-affiliated: we recommend the series that fits your lot, not the one with the best dealer incentive.
- Local to the valley floor: we understand what seasonal groundwater does to paver bases in Interlaken.
- Genuine components: OEM restraints and Unilock-spec polymeric sand, never mismatched aftermarket substitutes.
- One accountable team: San Mateo Construction manages the whole scope, from base excavation to final joint sand.

Common Unilock Construction Problems We Solve in Interlaken
- Paver settlement and rutting on low valley lots. Brussels Block and Town Hall pavers laid over a thin base will heave and rock when seasonal high groundwater softens the subgrade. We see this constantly on Interlaken lots near the Pajaro River flats. The fix is excavation and a deeper compacted aggregate base, not shimming a few pavers and hoping.
- Efflorescence and joint-sand washout after wet winters. Beacon Hill Flagstone gets chalky white deposits after Pajaro Valley rain cycles, and the joints open as sand migrates. We clean and stabilize the surface, then re-sand with a polymeric product that stays put through the next wet season.
- Edge restraint failure on flood-prone parcels. Where pavers meet grade without proper edge restraint tied to a stable base, the field spreads and borders shift. Common on the ag-adjacent Interlaken parcels where a driveway slopes toward a drainage swale.
- Polymeric joint sand breakdown and drainage-path clogging. If the base wasn’t graded to move water away from the foundation, stormwater pools, the sand degrades, and pavers start working loose. We re-grade first, then re-sand.
- Driveway channeling toward the house. We replaced a heaved Brussels Block driveway off a low Interlaken lane near the farmland edge where water was running straight at the foundation. Excavation, re-grading, new restraint, new sand: the drive has stayed tight through two wet seasons.
Unilock Service in Interlaken: What Local Conditions Mean for Your Equipment
Interlaken sits on the low Pajaro Valley floor near the Pajaro River, and that single fact drives more Unilock failures here than any product defect ever will. A paver driveway or patio on an older Interlaken home is only as good as what’s under it. The water table rises in winter, the clay-rich valley soil holds moisture, and a base that would be perfectly fine on a higher inland lot in Watsonville turns spongy here. Pavers heave, joints open, edges wander. We’ve walked rural-residential Interlaken parcels off the farmland edge where the driveway looked fine in August and was rocking like a boat dock by February.
What this means for Unilock owners is practical: your base needs to be deeper and denser here than the manufacturer’s generic spec suggests. We compact in more lifts. We grade to shed water toward the ag edge or the swale, never toward the foundation. We use a heavier edge restraint because hydrostatic pressure pushes harder on a flat lot than on a hillside. If the subgrade is compromised by groundwater, we rebuild it rather than patch over it. That’s the difference between a Unilock driveway that drains and one that fails.
Unilock Models & Products We Service in Interlaken
We install and repair the Unilock series that make sense on Interlaken’s flat, wet lots: Brussels Block, Beacon Hill Flagstone, Town Hall, and Bristol Valley. Each has a different structural profile, and we match the series to the use. A Brussels Block driveway carries different loads than a Beacon Hill Flagstone patio, and the base spec changes accordingly.
For parts, we use genuine Unilock pavers and compatible OEM edge restraints and polymeric sand. When a base is sound, we lift and re-lay existing pavers and reset the restraint. When the subgrade is compromised, we rebuild the base. No mismatched aftermarket pavers that fade to a different color in six months. No generic sand that washes out in one wet Pajaro Valley winter.

FAQs – Unilock Construction in Interlaken
Brussels Block or Town Hall usually wins on older Interlaken homes because both hold a tight, traditional look that fits modest 1950s and 60s ranch houses better than a modern plank profile does, and we also handle Amesti Unilock service. The real question is base depth and drainage, which matter more than the paver itself on a low valley lot. Call (855) 901-7266 and we’ll walk the site and tell you what we’d use.
That’s efflorescence: mineral salts migrating through the paver as Pajaro Valley groundwater rises and evaporates. Wet winters bring it out on Beacon Hill Flagstone and Brussels Block alike. It’s cosmetic, but it usually comes with joint-sand washout, which isn’t. We clean the surface and re-sand with a proper polymeric product so joints stay closed.
Usually yes. If the base under the settled section is still sound, we lift the affected pavers, re-compact, and reset them with fresh bedding sand and joint material. If the subgrade is soft from groundwater, a partial patch won’t hold. We’ll tell you which situation you have before we touch anything. For a quote on Unilock service in Freedom or a patio repair in Interlaken, call (855) 901-7266.
A typical driveway runs five to eight working days, depending on base depth and drainage work. A patio is usually three to five. Interlaken lots near the river flats often need extra excavation and compaction time, which adds a day or two. We give you a schedule in the written quote.
No. San Mateo Construction is an independent general contractor that installs and repairs Unilock products with genuine components, including Unilock repair in Corralitos. Independence matters on the Pajaro Valley floor: we recommend the series your lot actually needs, not the one a manufacturer program tells us to push.
