Unilock Construction in Gilroy, CA | Timberline Contractors
We provide independent Unilock construction and repair across Gilroy, from paver patios to driveways and retaining walls. What makes our Unilock work different here is simple: we know what sits under the soil on the east and south edges of town, because we’ve dug into it hundreds of times. Former garlic and orchard fields leave behind surprises that generic paver installers don’t plan for. We do.
Nelson Fung, owner and general contractor at Timberline Contractors, has spent years on job sites across the LA basin and now brings that hands-on experience to Gilroy hardscape projects. We’re not a manufacturer-authorized dealer. We’re an independent installer who works with Unilock products because they perform, and we know exactly how to make them perform on Gilroy ground. Call (866) 253-5808 for a free estimate on paver patio installation, paver driveway installation, or driveway replacement.
Why Gilroy Residents Choose Us for Unilock Service
Choosing a contractor for Unilock work in Gilroy isn’t the same as choosing one in San Jose or Morgan Hill. The soil here shifts, the summers bake, and the ground underneath a paver field can hide things that were buried decades before any subdivision was platted. We understand that because we’ve worked it.
Nelson grew up in Chinatown, Los Angeles, spending Saturday mornings watching his grandfather debate tile prices at hardware stalls on Broadway. That early exposure to materials stuck. He learned construction formally at Los Angeles Trade-Technical College before years of hands-on work on remodels and commercial builds. The obsession with getting substrate right comes from seeing what happens when it’s done wrong. He’ll tell you straight: paver failure is rarely about the paver. It’s about what’s underneath.
We match Unilock’s own units and compatible edge restraints and polymeric joint sand so repairs blend with the existing field. When you call us for a rocking paver or a washed-out edge on a Gilroy patio, you get someone who knows the product line and knows the ground it sits on.

Common Unilock Construction Problems We Solve in Gilroy
Here’s what we see most often on Unilock installations in Gilroy, and what’s really causing each one.
- Rocking and shifting pavers after hot summers. Gilroy regularly hits 90s and 100s during summer. That heat dries and shrinks the bedding sand, and once the edge restraint fails, pavers start moving. We see this on Brussels Block patios installed by crews who skimped on edge support or used the wrong bedding depth.
- White efflorescence and staining on paver surfaces. Expansive adobe-clay wicks moisture up through the base, especially where drainage wasn’t corrected before installation. Minerals come with it and leave chalky white deposits. This is a drainage problem, not a paver problem, and topping off sand won’t fix it.
- Settling and trip edges on former orchard or garlic ground. Eastern and southern Gilroy lots were farmland. Undocumented irrigation lines and buried stumps get hit during excavation. If they aren’t cleared and the clay isn’t re-compacted properly, the base settles and you get dips and raised edges that are a safety hazard.
- Base erosion and rutting after winter rains. Gilroy’s seasonal rains hit hard on graded slopes. When runoff flows toward or across a paver field instead of being directed away, the base erodes from underneath. What looks like a surface problem is actually a drainage failure.
- Faded or stained Cambridge Pavingstones on driveway surfaces. The inland heat and valley dust combine to accelerate surface wear. We see driveways where the right paver was installed but the wrong sealer, or no sealer, was applied afterward. That’s a fixable situation, but only if caught before the surface pitting gets deep.
Unilock Service in Gilroy: What Local Conditions Mean for Your Equipment
Here’s a fact about Gilroy that doesn’t show up on most contractor websites: lots on the eastern and southern edges of town sit on former garlic and orchard fields, and the irrigation lines and buried stumps from that agricultural past were never documented in county records. When we excavate for a paver base in those neighborhoods, we routinely hit obstructions that have to be cleared and re-compacted before any Unilock unit goes down. That means our base prep takes longer than it would on a clean suburban lot in a neighboring city, and it means we budget for it honestly in the estimate.
On a lot off the eastern edge of Gilroy in the 95020 ZIP, our crew started a Unilock Brussels Block patio excavation and hit an old irrigation line and a buried stump that weren’t on any record. We pulled the obstruction, over-excavated the adobe-clay, re-compacted in lifts, and set a thicker base with drainage directed away from the house, then laid the Brussels Block. The patio has stayed flat through two rainy seasons with no rocking or pooling. That’s what we mean when we say we build for Gilroy ground, not for a manufacturer’s generic checklist.
Unilock Models & Products We Service in Gilroy
We work with the full range of Unilock hardscape products on Gilroy projects. The Brussels Block tumbled concrete paver is the most common patio surface we install and repair. Beacon Hill, the flagstone-style paver, shows up often on custom patios and walkways. For driveways, we install Cambridge Pavingstones with ArmorTec, which stands up well to the inland heat when the base is done right. We also build with Unilock coping and retaining wall units, including the Brussels Dimensional System.
When a repair calls for matching units, we pull the same Unilock paver and blend it with the existing field rather than ripping up a sound installation. But when the base or drainage is the real failure, honest repair means rebuilding the affected section. We don’t just top off sand and call it done. That’s the difference between a fix that lasts and one you’ll be calling about again next summer. You can browse our broader Unilock sales & service page to see how we handle the full product line.

What drives the cost on any given Gilroy lot is what’s underneath. A clean site with easy access sits near the low end. A former orchard lot where we have to clear buried stumps, re-compact clay, and redirect runoff sits higher, because that’s real work that prevents failure later. Every free estimate we give includes a written line-item breakdown so you see exactly where the money goes. Call (866) 253-5808 to schedule yours.

FAQs – Unilock Construction in Gilroy
Rocking pavers and disappearing joint sand point to a base or edge restraint problem, not a paver defect. Gilroy’s hot, dry summers shrink the bedding; once the edge loses its grip, the whole field loosens. The fix is rebuilding the affected section with proper compaction and a secure edge, which we do on a regular basis across Gilroy and with Morgan Hill Unilock service. Call (866) 253-5808 to have us look at it – the estimate is free.
Yes, and we do it often. The key is over-excavation and re-compaction in lifts after removing buried stumps or abandoned irrigation lines, then laying a thicker base with drainage directed away from the house. We’ve installed paver driveways on former orchard and garlic parcels across eastern Gilroy’s 95020 ZIP that have stayed flat through multiple rainy seasons, and we also handle Unilock repair in Aromas.
White deposits on pavers are minerals wicking up through the base from Gilroy’s expansive adobe-clay, typically where drainage wasn’t corrected before installation. We fix it by addressing the moisture path: improving drainage, cleaning the surface properly, and sealing if the paver type warrants it. Topping off sand alone won’t stop it.
We use genuine Unilock units for partial repairs and pull matching pavers so the new area blends with the existing field, including San Martin Unilock service jobs nearby. If the original installation used a discontinued color or line, we’ll show you the closest available match and explain the difference before any work starts.
Without proper drainage, yes – Gilroy’s winter rains can erode a paver base on graded slopes that weren’t prepared to move water away from the field. We correct this by regrading or adding drainage before rebuilding the base. Call (866) 253-5808 and we’ll assess the slope and give you a straight answer on what it will take, whether in Gilroy or for Unilock repair in San Juan Bautista.
