Unilock Construction in Castroville, CA | Iron Beam Contractors
We install and repair Unilock in Prunedale and across Castroville as an independent contractor, which means we answer to you, not a dealer program. The thing that changes Unilock work here more than anything is the marine layer: it keeps paver surfaces damp most of the year, so base, pitch, and joint sand have to be spec’d differently than they would be ten miles inland. If you’re pricing out a paver driveway, patio, or replacement in the 95012, call (833) 756-5936 for a free estimate.
Why Castroville Residents Choose Us for Unilock Service
Most crews in the Salinas Valley know dry conditions. Castroville isn’t dry. Our teams work in this fog belt weekly, so we size open-graded base and steeper falls for damp, poorly drained lots instead of copying an inland spec. Nolan Driscoll grew up in Orange County and spent enough afternoons at Santiago Oaks as a kid to understand soil, grade, and clay layers before he ever touched a beam. He built Iron Beam Contractors on one straightforward principle: tell the homeowner exactly what’s in the ground before you open it, not after. We carry Unilock’s own matching pavers and compatible polymeric sand for repairs so color and profile stay consistent, and we source quality aftermarket base aggregate and edging where the brand name doesn’t matter. We’re a general contractor with a hardscape focus, not a paver broker, and we stand behind the full scope. See our full Unilock sales & service approach.

Common Unilock Construction Problems We Solve in Castroville
- Polymeric joint sand that never cures. The marine layer keeps joints damp for weeks, so standard sand washes out and edges shift. We spec polymerics that cure in cool, humid conditions and re-sand the joints properly.
- Efflorescence and dark staining on shaded fields. North-facing stucco and shaded paver areas in the town core stay wet most of the day. We clean the surface and address drainage so the staining doesn’t return every season.
- Base failure from saturated subgrade. Castroville sits on flat, poorly drained lots, so water ponds under pavers instead of shedding. We test the subgrade before quoting and often switch to an open-graded base that drains.
- Edge restraint loosening in older yards. Damp soil and root movement in established town-core lots push against borders. We pull the restraint, re-set the edge, and compact the base so the field stays tight.
- Heaved or shifted fields from prior bad work. We see this often near Castroville Boulevard where old concrete was poured without drainage. We lift, re-grade, and re-base rather than patching over the problem.
Unilock Service in Castroville: What Local Conditions Mean for Your Equipment
There’s one thing about Castroville that a generic Unilock page won’t tell you: the near-constant marine layer means your paver field will be damp for most of the year, and that changes the whole installation spec. We routinely see Unilock service in Las Lomas and from inland crews where the base was compacted crusher run and the pitch was a quarter-inch per foot. That works in dry heat. It doesn’t work here. The fog off the Monterey Bay coastal plain keeps the surface wet, so water has to move off the field fast and the base has to drain freely. We spec a steeper fall, usually three-eighths to a half-inch per foot, and an open-graded aggregate base instead of dense crusher. On a modest single-story stucco home near the Castroville Boulevard corridor, we tore out a heaved concrete driveway and set a Unilock Brussels Block field on exactly that base with a steeper fall to the street. The original pour had ponded against the garage slab under fog moisture, so we re-graded first, added a drainage plane to the north-facing wall footing, and locked the border with edge restraint. The pavers have stayed tight through two damp winters. That’s the difference between a spec written for inland Salinas and one written for Castroville’s fog belt.
Unilock Models & Products We Service in Castroville
We install and repair the Unilock lines we see most often in the 95012: Brussels Block, the tumbled concrete paver that handles residential driveways well; Beacon Hill, the irregular-profile paver for patios and walkways; Brussels Dimensional System for a tighter, modular look; Copthorne for a clay-look finish; and the Oaks and Estate Wall retaining systems. For Unilock repair in Pajaro and here, we use Unilock’s own matching pavers so color and profile stay consistent. For base aggregate and edge restraint we use quality aftermarket products, because the brand on those materials doesn’t affect the finished field. We keep common Unilock pavers in rotation for faster Castroville turnaround, and we can order specialty lines when the project calls for it.

AfterUnilock Service Pricing in Castroville
What you’ll pay depends mostly on the size of the field, the condition of the subgrade, and whether we’re doing a fresh install or a tear-out. Here’s where our General Contractor in Castroville jobs typically land:
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |

| Driveway Replacement | $5,000 – $14,000 |
| Concrete Driveway Installation | $4,500 – $12,000 |
If your subgrade is saturated from the fog belt, we’ll tell you before we quote, because open-graded base adds material cost now and saves you a failed field later. Our free estimate includes a subgrade check, drainage review, and a written line-item price. Call (833) 756-5936 to schedule one.

FAQs – Unilock Construction in Castroville
Yes. We use a polymeric sand formulated for cool, humid curing, because the marine layer keeps joints damp long enough that standard polymerics fail to set and wash out. Salinity is less of an issue than persistent moisture, but we account for both when we spec the sand. If your joints are already washing out, call (833) 756-5936 for a re-sand quote.
No. We’re an independent contractor who installs and repairs Unilock products. That’s deliberate: we recommend what the project needs, not what a dealer program pushes. We carry Unilock’s matching pavers for repair work because color and profile consistency matter on a repair. We’re not manufacturer-affiliated.
For matching pavers, yes. We source Unilock’s own units so a repaired section doesn’t look like a patch. For base aggregate and edge restraint, we use quality aftermarket products, because the brand on those materials doesn’t change the finished look or performance.
Most paver driveway replacements run three to five working days from tear-out to final compaction. The marine layer can add a day for polymeric sand curing, since we wait for the surface to dry enough for the sand to set properly. We’ll give you a clear schedule before we start.
Expect $3,500 to $11,000 depending on size, access, and whether we’re pulling old concrete first. Fog-belt drainage work, like a steeper fall or open-graded base, adds material cost, but it’s the difference between a patio that lasts and one that stains and shifts within a season. Call (833) 756-5936 for an exact quote.
