Unilock Construction in Gilroy, CA | Seaside Contractors
We install and repair Unilock segmental retaining walls, pavers, and permeable systems across Gilroy’s subdivisions and rural fringe, and we handle the brand as an independent service provider, not a manufacturer arm. The thing that separates Unilock work here from the same job in Morgan Hill Unilock service or Hollister is jurisdiction: a wall or driveway on one side of a road can fall under the City of Gilroy building department, while the parcel across the street answers to unincorporated Santa Clara County. That shapes everything from permit sequencing to which inspection standards apply, and we’ve been navigating both paths long enough that it’s second nature. Call (833) 589-8103 for an assessment.
Why Gilroy Residents Choose Us for Unilock Service
Unilock paver and wall systems show up all over Gilroy, from patios in the downtown core’s older single-family homes to driveways in the 2000s-era subdivisions east of 101 and retaining walls on acreage properties off leaves like Hecker Pass and Frazier Lake Road. We’ve spent years digging into failed walls across this specific terrain, which means we know how Unilock’s Tandem and U-Cara lines behave under Gilroy’s clay-heavy soils and why Uni-Decor pavers fade the way they do under hard summer UV and dry-season dust. Glen Sorrento, our owner, studied building construction technology at College of San Mateo and has spent more than two decades working through nearly every project type, so the question on a Unilock job is never “do we know this product” but “what does this site actually need.” We use genuine Unilock units, caps, and geogrid where matching existing color and profile matters, and we also provide Unilock repair in Aromas for properties in that area, and quality aftermarket base aggregate and polymeric sand where it doesn’t. Being independent means we can make that call honestly.

Common Unilock Construction Problems We Solve in Gilroy
- Batter and toe failures on Tandem and U-Cara walls. These happen when geogrid was shorted or never tied into the reinforced soil zone, and on Gilroy’s clay-heavy fringe lots the problem shows up after a wet winter when saturated soils push the wall face out. We pull the front units, re-compact, install proper geogrid courses, and reset the blocks.
- Efflorescence and color fade on Uni-Decor pavers. Gilroy’s summers are hot and dry, and hard UV combined with fine windblown dust breaks down unsealed paver surfaces faster than most manufacturers’ brochures admit. Surface sealing skipped at install becomes obvious within two or three seasons here.
- Joint sand washout and edge creep on driveways and patios. Polymeric sand broadcast too thin, or edge restraint not set into the base, means the Gilroy rainy season quietly migrates your pavers outward. We see it most on driveways where the sand was never compacted into the joints at full depth.
- Base failure on permeable pavers. Gilroy’s fine dust chokes open-graded aggregate over time, and if the voids were never vacuumed during maintenance, the system stops draining. We rebuild the base with properly washed aggregate and re-establish the infiltration zone.
- Failed edge restraint on paver driveways. When the edge isn’t anchored into the base with concrete or a proper restraint system, Gilroy’s persistent seasonal winds accelerate the creep. The fix is pulling, re-grading, and resetting the border before the field.
Unilock Service in Gilroy: What Local Conditions Mean for Your Equipment
Here’s the thing about Gilroy that a generic Unilock page won’t tell you: the city’s growth boundary and adjacent unincorporated county land mean neighboring parcels can fall under different building authorities, so the first question on many hardscape jobs is which jurisdiction’s permit and inspection apply. A Tandem wall on a lot west of Santa Teresa Boulevard might be a City of Gilroy project, while the same wall a quarter mile south could be unincorporated Santa Clara County territory with a different permit path and different inspector expectations. Add rural-edge defensible-space requirements, and you have a situation where the hardscape you place next to a structure isn’t just aesthetic, it’s part of the fire-safety review. We’ve rebuilt leaning retaining walls in both jurisdictions and know which forms, which details, and which sequencing each one wants, including San Martin Unilock service projects nearby. Let’s figure out what the job actually needs, then we’ll talk materials.
Unilock Models & Products We Service in Gilroy
We work on Brussels Block in both Brussels Dimensional and Brussels Fullnose profiles, Uni-Decor and Uni-Stone interlocking pavers, Tandem modular retaining wall systems, and U-Cara faced retaining walls. For matching existing color and profile, we source genuine Unilock units, caps, and geogrid, and we keep base aggregate and polymeric sand stocked so most Gilroy jobs don’t sit waiting on material. A wall with a bad base doesn’t get fixed by new blocks. We rebuild the foundation and reinforcement before we reset the material, which is the difference between a repair that holds and one that leans again in two years. This is all part of our broader Unilock sales & service work across the South Bay and beyond.

AfterUnilock Service Pricing in Gilroy
Labor and material costs for Unilock work in Gilroy run close to what we quote across the southern Santa Clara Valley corridor, with site access and prep dictating most of the variance. A sloping lot with poor drainage costs more than a flat subdivision parcel. Here’s the range we see on typical jobs:
| Project | Typical Range |
|---|---|
| Paver Patio Installation | $3,500 – $11,000 |
| Paver Driveway Installation | $7,000 – $18,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Driveway Sealing | $250 – $700 |
What drives the number: wall height and geogrid requirements on sloped lots, the condition of the existing base and whether it needs full excavation, and access for equipment. Every estimate includes a written line-item breakdown and a site walk so you know exactly what’s being bid. Call (833) 589-8103 to schedule a free one.

FAQs – Unilock Construction in Gilroy
Yes, if you want to slow color fade and efflorescence. Gilroy’s summer UV and windblown dust break down unprotected paver surfaces faster than inland coastal areas with cooler mornings and higher humidity, so we recommend sealing Uni-Decor and Uni-Stone surfaces every two to three years depending on sun exposure. Call (833) 589-8103 for a sealing assessment and exact quote.
Most leaning Tandem walls in Gilroy are repairable if the face units are intact and the failure is in the geogrid or base, not the block. We pull the front units, re-compact and re-grade, install proper geogrid with drainage aggregate and a perforated outlet, then reset and cap. If the base has failed badly or the wall is twisting, full rebuild may be cheaper than patch work. An estimate tells you which path applies to your site.
It depends on the parcel. Jobs inside Gilroy city limits go through the City of Gilroy building department; parcels just across the growth boundary fall under unincorporated Santa Clara County. The permit path, fees, and inspection sequence differ between the two, and rural-edge properties may also trigger defensible-space review. We determine jurisdiction before we bid, so there’s no surprise mid-project.
They can, but only if the open-graded aggregate stays clean and the base is sized for your soil infiltration rate. Gilroy’s fine windblown dust chokes permeable systems faster than most people expect, and clay-heavy ranch soils slow infiltration. We spec the right depth, the right aggregate, and a maintenance schedule that keeps the system draining. Call (833) 589-8103 for a site-specific recommendation.
For a typical Gilroy home, replacing a worn paver driveway runs $5,000 – $14,000 depending on driveway size and base condition, while adding a paver patio lands between $3,500 and $11,000. Doing both together usually saves on mobilization and excavation. Call (833) 589-8103 for a combined quote; estimates are free.

We rebuilt a leaning Tandem retaining wall at the back of a sloped lot off the historic downtown core, where the wall had been built without geogrid tied into the reinforced zone and was pushing out after a wet winter. We pulled the face units, re-compacted and re-graded the base, installed proper geogrid courses with drainage aggregate and a perforated outlet, then reset the Tandem blocks and capped them flush. Our techs also re-leveled the Uni-Decor patio pavers the failed wall had heaved. That’s the kind of repair that separates a wall that holds from one that leans again.
