Unilock Construction in Interlaken, CA | Daly City Construction
We’re Unilock specialists serving Interlaken and the wider Pajaro Valley, and we handle everything from paver driveways to patios, retaining walls, and driveway replacements. The thing that sets our Unilock work here apart is that we build for unincorporated Santa Cruz County realities: ag-zone drainage, coastal fog, and county permitting. Call (866) 505-5254 for a free estimate on any Unilock project in Interlaken.

Why Interlaken Residents Choose Us for Unilock Service
Unilock pavers are built to last, but only if the base, edge restraint, and drainage are done right. That’s where most installations fall short, and it’s exactly the work we do every week across Interlaken and the Pajaro Valley. Noel Cabrera, our owner at Daly City Construction, grew up around tract homes in Daly City’s Westlake district and has spent years dealing with moisture-heavy coastal construction. He knows what fog and winter rain do to a paver base. When we scope a Unilock job in Interlaken, we’re thinking about where water goes, how the clay moves, and whether the county wants a drainage plan, not just what the finished patio will look like.
We carry Unilock’s own edge restraint, joint sand, and wall connectors because aftermarket substitutes don’t match the block geometry. On damp, shifting ground, that difference shows up within a season or two. You get one crew, one point of contact, and a paver installation that stays put.

Common Unilock Construction Problems We Solve in Interlaken
Unilock product is engineered well, but Interlaken’s conditions expose weak installation fast. Here are the failures we see most often:
- Paver joint sand washout and field shifting after winter rains. Interlaken gets real rain from November through March, and rural driveways and patios without proper edging lose joint sand quickly. The pavers migrate, gaps open, and the whole field starts drifting. We re-sand with Unilock’s polymeric joint sand and set proper edge restraint.
- Efflorescence and algae staining on light pavers under summer fog. Coastal fog and damp marine air settle on north-facing patios and shaded areas around barns and outbuildings. Brussels Block and lighter Unilock colors show white mineral bloom and green algae faster here than inland. We clean, re-sand, and often recommend a darker block or sealant for those spots.
- Bases that were never designed for ag-zone runoff. Water pooling against barns and outbuildings undermines paver bases along field edges. The pavers settle, heave, or crack. We rebuild the base with proper compaction and slope the grade away from the structure before resetting the block.
- Retaining wall block separation or lean on expansive clay. The Pajaro Valley has its share of expansive clay that moves with moisture. Shallow footings without drainage tile behind the wall cause Unilock garden and retaining walls to lean or separate within a few years. We fix the drainage first, then rebuild the wall.
- Driveway settlement along barn aprons and outbuilding pads. Rural acreage driveways in Interlaken see tractor traffic, ranch trucks, and equipment loads that a standard residential base was never compacted for. Edges sink, and blocks crack under point loads. We compact deeper and spec paver thickness for the actual use.
Unilock Service in Interlaken: What Local Conditions Mean for Your Equipment
Here’s the part most paver contractors miss about Interlaken: it’s unincorporated Santa Cruz County, which means significant construction runs through county permitting out of Santa Cruz, not a city building department. A company working neighboring Watsonville or Gilroy is operating under a different permit authority and a different set of rules. For Unilock work specifically, that changes things. A paver driveway or patio in Interlaken can trigger ag-zone review if the parcel is in the Pajaro Valley agricultural zone, and that can pull in farm-related and water/septic rules a purely residential contractor wouldn’t anticipate. We have worked through enough county permit cycles on rural acreage in Interlaken to know what the planners ask for: drainage plans, pervious area calculations, sometimes septic field setbacks. If you’re putting a paver patio behind a barn or expanding a driveway apron off a country road, you want someone who’s seen that file before. We have. That’s not a Watsonville or Gilroy mindset; it’s specific to living and building in unincorporated Santa Cruz County.
Unilock Models & Products We Service in Interlaken
We install and service the full Unilock residential paver and wall lineup most common in the Pajaro Valley: Brussels Block, Beacon Hill, Onyx, and Seneca East. Brussels Block is the workhorse for rural driveways because it handles heavy loads when the base is built right. Beacon Hill and Onyx give you a more finished look for patios and walkways, and Seneca East does well for garden walls and edging. We stock Unilock’s joint sand and edge restraint locally for fast turnaround on Unilock repair in Corralitos and Interlaken, and we can order specific block lines from our regular supply chain without the showroom runaround.

FAQs – Unilock Construction in Interlaken
Yes, if the base is built for the load. Brussels Block and similar Unilock pavers handle ranch trucks and light tractor traffic when the sub-base is compacted deeper and the edge restraint is properly set. Standard residential base depths won’t cut it on Interlaken acreage. We spec the base to the equipment you actually run, not a generic driveway standard. Call (866) 505-5254 and we’ll walk the driveway with you before quoting.
No. Daly City Construction is an independent Amesti Unilock service provider serving Interlaken and the Pajaro Valley. We’re not manufacturer-affiliated. That means our recommendations come from what holds up on damp, shifting ground and what survives county permitting, not from a sales quota.
We use Unilock’s own edge restraint, joint sand, and wall connectors. Aftermarket substitutes don’t match the block geometry, and on Interlaken’s fog-damp clay they fail faster. Where an existing installation is structurally sound, we re-sand and re-set rather than replace. Full replacement only happens when the base itself is compromised.
A straight paver patio repair can be done in a day or two. A full driveway replacement with base rebuild and drainage work typically runs one to two weeks, longer if county permit review for an ag-zone parcel is involved. We’ll give you a straight timeline before work starts, not after.
Paver driveway installation runs $7,000 to $18,000, paver patios $3,500 to $11,000, and driveway replacement $5,000 to $14,000. Interlaken’s county permitting and ag-zone drainage requirements can add scope that a straight residential quote won’t include. Call (866) 505-5254 for an exact figure, estimates are free.
