AfterUnilock Construction in San Jose, CA | Rowan Construction Group
We provide independent Unilock paver installation, repair, and re-leveling across San Jose, from Berryessa to Almaden Valley. What makes our Unilock work different here is that we build for Altamont clay soil movement, not just for looks. If you’re pricing a paver driveway, patio, or walkway in San Jose, call (470) 298-9650 and we’ll put a written number in front of you before anyone picks up a shovel.
Why San Jose Residents Choose Us for Unilock Service
Fence Installation in San Jose starts with the same principle: Unilock pavers are a premium product, and they deserve installation that accounts for San Jose’s specific ground conditions. Our crews have spent years working with Unilock’s real product lines: Eco-Priora permeable pavers, Town Hall clay pavers, Richcliff and Beacon Hill flagstone, and the classic Hollandstone and Brussels Block. We know which ones hold up on expansive clay and which ones need extra base work. Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College, where estimating and concrete work were part of the curriculum before he ever ran a job site. That training shows up in how we quote: line by line, with the paver count, base depth, and drainage plan written down.
We’re an independent Unilock service provider, not a manufacturer-authorized dealer. That distinction matters. It means when a paver patio in San Jose starts heaving, we can recommend the repair that actually fits the problem, which is sometimes a partial re-lay of eight pavers instead of a replacement quote for the whole surface. We also carry what San Jose jobs need most: sealed bags of Gator Base panels and Techniseal polymeric sand so we’re not waiting on a distributor when our Driveway & Pavers in San Jose edge is sinking.
You can read more about how we approach the broader Unilock sales & service work, but the short version is this: we source replacement pavers directly from Unilock’s local distributor to guarantee color and dimension match, and we write the price down before work starts. That’s Clause 1 of our Haven Standard, and it’s been how we’ve run 4,000-plus projects since 2007.
Common Unilock Construction Problems We Solve in San Jose
- Heaving and shifted pavers from expansive clay. San Jose’s Altamont-series clay soils shrink in our dry summers and swell when winter rain returns. That cycle pushes pavers up unevenly, especially on raised driveways common to 1950s tract homes in Berryessa and East San Jose. We re-level by pulling the affected area, rebuilding the base, and re-laying the same pavers where they’re still intact.
- Faded or etched surfaces on Richcliff and Town Hall pavers. Inland UV in San Jose hits harder than what coastal cities like Santa Cruz see. Add hard water from irrigation in Almaden Valley, and you get mineral staining that dulls the paver face. We clean, re-sand, and seal, or replace individual units when the surface is too far gone.
- Base washout and edge spalling along driveways. Many San Jose ranch homes have downspouts that dump roof runoff directly onto paver edging. Over a few winters, that water undermines the base and the edge pavers start chipping. We reroute drainage and rebuild the affected edge before it spreads.
- Polymeric sand joint failure from seismic micro-shifts. Along the Hayward-Calaveras corridor, small ground movements work paver joints loose over time. In Willow Glen, we see this as weeds and ant trails pushing through joints every spring. We re-sand with Techniseal and address the drainage that’s feeding the weeds.
- Cracked individual pavers from tree roots or point loads. A single cracked unit doesn’t require a full re-pave. We cut and replace individual pavers when less than 30% of the surface is compromised. We only recommend full replacement when the base has turned to mush.
BeforeAfterUnilock Service in San Jose: What Local Conditions Mean for Your Equipment
San Jose’s mandatory Soft-Story Retrofit Ordinance doesn’t apply to single-family homes, but it’s quietly shaped how the best hardscape work gets done in this city. That ordinance created a local ecosystem of pre-approved structural contractors who now apply the same engineered retrofit discipline, think prescribed drainage setbacks and base-compaction specs written for multifamily buildings, to residential paver jobs. We borrow from that playbook. When we install a Unilock paver driveway in Cambrian or a patio in Berryessa, we’re compacting the base to a standard most paver crews don’t bother with, because we’ve seen what a Loma Prieta-level shake does to a loosely set surface. It’s not overbuilding. It’s building for the city we actually work in. For a broader look at where we operate, see our San Jose service area page.
One job sticks with us. We tore out a heaving Richcliff driveway in Berryessa where the original 1970s slab underneath had cracked along a visible clay-swell line. After removing the old pavers, our techs laid new Gator Base over compacted gravel, re-screeded with sharp sand, and re-laid the same pavers with fresh Techniseal poly sand. The homeowner needed only eight replacement units because the originals were still intact. That’s the San Jose-specific repair a generic dealer won’t propose: save the pavers, fix the base.
Unilock Models & Products We Service in San Jose
We work across the Unilock lines most common in San Jose yards and driveways. Eco-Priora permeable pavers show up on newer builds where drainage is a concern. Town Hall clay pavers are a favorite on older Berryessa and Cambrian porches and steps, where their color holds up if the sealer is maintained. Richcliff and Beacon Hill flagstone are the go-to for patios and fire-pit areas in Almaden Valley and South San Jose. Hollandstone and Brussels Block dominate driveways across the valley floor. For every line, we source replacements from Unilock’s local distributor so color and dimension match the existing installation. When repair is the right call, we stock Gator Base panels and Techniseal poly sand on our trucks for same-visit base rebuilds.
Unilock Service Pricing in San Jose
Here’s what Unilock paver work costs in San Jose, based on typical project sizes and our current labor and material rates. These are written-price ranges, not “call for a quote” placeholders:
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $8,260-$21,240 |
| Paver Patio Installation | $4,130-$12,980 |
| Driveway Replacement | $5,900-$16,520 |
What drives the number is base depth, drainage work, and how much of the existing surface can be salvaged. A flat paver patio in Cambrian will land at the lower end. A raised driveway in Berryessa with clay heave and a failed base will run higher. Every estimate includes a written scope, a written warranty, and a documented photo record of what we found. Call (470) 298-9650 for an exact written quote, it’s free, and we’ll walk the site before we write any number.

FAQs - Unilock Construction in San Jose
Yes. We order replacement pavers directly from Unilock’s local distributor using the original color code from your installation, so the match is exact, not close. If the existing units are too weathered for a seamless blend, we’ll show you samples and tell you honestly whether a small replacement set will stand out. Call (470) 298-9650 and we’ll bring color chips to your porch.
We over-excavate the clay, lay a geotextile fabric, compact a deeper gravel base than the standard, and then set the pavers on a screeded sand bed. On driveways and areas with known swell lines, we add Gator Base panels to bridge small movements. It’s the same base discipline the city’s soft-story retrofit contractors use on engineered fills. Call (470) 298-9650 and we’ll explain what your specific yard needs.
Yes, and that’s a repair we recommend before the lip spreads into the main field. We’ll cut and remove the apron pavers, rebuild the base where the street transition failed, and re-lay the same units with fresh poly sand. If the lip was caused by a settling sub-base, we’ll compact it properly before reinstalling. Call (470) 298-9650 for a written repair price.
Eco-Priora works in San Jose if the base is designed for it, meaning a deep open-graded stone reservoir below the pavers, not a standard sand bed. On expansive clay, you need that reservoir to handle water that can’t percolate into the clay itself. We install them correctly, and we also tell homeowners when a standard paver with surface drainage is the better long-term call. Call (470) 298-9650 and we’ll assess your yard’s drainage honestly.
No sealer stops weeds permanently, but we can get you to a place where they stop coming back every spring. We remove the old poly sand, treat the joints, re-sand with Techniseal, and address the drainage that’s feeding the weed roots. If you want, we’ll also apply a sealer that helps the joints resist erosion. Call (470) 298-9650 for a written number, and we’ll tell you what’s actually growing in there and why.
