Unilock Construction in Fresno, CA | Penhallow Remodeling
Unilock construction in Fresno means paver patios, driveways, walkways, and retaining walls built on some of the most reactive soil in California. We’re Penhallow Remodeling, a General Contractor in Fresno and an independent Unilock service provider, not authorized or sponsored by the manufacturer. What makes our Unilock work different here is simple: we design every base and drainage system around Fresno’s expansive adobe clay, because that’s the factor that decides whether your pavers stay flat for two decades or start heaving in two seasons. Serving all of Fresno, from the Tower District to northwest tract subdivisions. Call (936) 259-2607 for a free estimate.
Why Fresno Residents Choose Us for Unilock Service
Trevor Nash grew up watching his uncle gut and rebuild older ranch houses in Reseda, and he spent nearly two decades on residential projects across California before starting Penhallow Remodeling. That background matters when you’re hiring someone to work on Fresno soil. We’ve torn out enough failed paver jobs in this city to know that the paver is rarely the problem. The base is. The drainage is. The way the system ties into a moving slab is.
We stock genuine Unilock pavers and matching wall units locally for fast Fresno turnaround, and we use compatible polymeric joint sand and aggregate sourced for this valley’s shrink-swell cycles. As an independent crew, we’re not tied to Unilock’s catalog or sales targets. If your existing system can be salvaged by rebuilding the base and relaying the same units, we tell you that. If replacement makes more sense, we tell you that too. Background-checked, uniformed technicians on every job. A written price before any work starts. And the 365-Day Done Right Promise in writing on every project.
Common Unilock Construction Problems We Solve in Fresno
- Edge spalling and joint sand loss where pavers meet post-tensioned slabs. In northwest Fresno’s 1990s – 2000s tract homes, slabs sit directly on expansive adobe clay and move with every wet-dry cycle. When pavers are pinned to those slabs, the edges crack and spall within a season or two. We rebuild the independent base and re-edge the border so the slab can move without tearing the paver system apart.
- Efflorescence and salt bloom on Brussels Block and Umbriano surfaces. Fresno’s mineral-heavy irrigation water leaves white salt deposits on paver faces after winter moisture cycles. It’s not a Unilock defect. It’s a local water chemistry issue compounded by overspray. We clean, neutralize, and where appropriate seal the surface so the finish holds.
- Paver heaving and lippage in driveways and patios. Seasonal shrink-swell cycles lift individual units, especially in 1990s – 2000s subdivisions across north and northwest Fresno. You’ll see a tripping hazard at the garage apron or a wavy patio surface. The fix is base reconstruction, not just re-leveling the top course.
- Faded or chalky color on older Copthorne clay pavers. Fresno sits in California Title 24 Climate Zone 13, with over 100 days annually above 90°F and UV peaks exceeding 110°F. South- and west-facing unsealed pavers take the worst of it. We can refresh the color and advise on sealer options that hold up under this valley’s sun.
- Retaining wall units shifting on clay backfill. Brussels Dimensional Stone wall units need proper drainage behind them. Fresno’s adobe clay holds water, swells, and pushes. Without an adequate drainage column and weep system, even well-installed walls start to lean. We rebuild them with drainage that accounts for the soil, not just the wall.
Unilock Service in Fresno: What Local Conditions Mean for Your Equipment
Here’s the piece most Unilock pages never touch. Fresno’s 1990s – 2000s northwest tract subdivisions were built on post-tensioned concrete slabs poured directly over expansive adobe clay. Those slabs dome and dish as the soil cycles through wet winters and dry summers. Driveways and patios that tie into those slabs with Unilock pavers have to be designed as independent systems with their own compacted aggregate base, their own drainage plane, and a deliberate separation from the moving slab. If you pin the paver border to the slab edge, the slab’s movement transfers straight into the pavers. You get cracked borders, lifted units, and stair-step separation at the garage apron within a season or two. Out-of-area crews frequently misread this as simple settling and patch the surface. It’s not settling. It’s the slab flexing on reactive clay. In a northwest Fresno subdivision off the 1990s – 2000s tract grid, our crew tore out a heaved Brussels Block driveway that a previous installer had set directly against a post-tensioned slab on expansive clay. We re-established a compacted aggregate base with proper slope away from the slab, re-laid the salvaged Brussels Block, and finished with polymeric joint sand sized for the valley’s shrink-swell swings. Two wet seasons later that driveway is still flat, with no new lippage at the garage apron. That’s the difference between understanding the soil and just laying pretty pavers.
Unilock Models & Products We Service in Fresno
We install and repair the full range of Unilock hardscape products you’ll find in Fresno. Brussels Block and Beacon Hill pavers for patios and walkways. Umbriano smooth pavers for a more contemporary look. Brussels Dimensional Stone wall units for seat walls, planters, and low retaining walls. Copthorne and Town Hall clay brick pavers for traditional drives and edges. For visible repairs, we use genuine Unilock units so color and texture match the existing installation. We don’t substitute generic lookalikes. For the base and joints, we source compatible aggregate and polymeric sand locally rather than defaulting to whatever mix happens to be on the shelf. That local sourcing matters here, because the aggregate has to compact properly over adobe clay, not just fill space.

FAQs – Unilock Construction in Fresno
Because the post-tensioned slab they’re tied to is doming and dishing on expansive adobe clay. The pavers aren’t failing; the connection to a moving slab is. The fix is to separate the paver system from the slab with an independent base and proper drainage. Give us a call at (936) 259-2607 and we’ll assess whether you need a border rebuild or a full base reconstruction. Estimates are free.
No. That’s efflorescence, and in Fresno it’s typically driven by mineral-heavy irrigation water and winter moisture wicking through the paver. The unit itself is intact. We clean and neutralize the surface, address the overspray source, and seal where it makes sense. Call (936) 259-2607 for an evaluation and a written quote.
Yes. We use genuine Unilock units from the same product line so the color and texture read consistent. For older lines like Copthorne clay pavers, we’ll source the closest current match and blend the repaired area with the surrounding field. The result won’t look like a patch. Call us at (936) 259-2607 to discuss your specific paver line and what’s available.
Yes, often. A properly built paver driveway with an independent base handles clay soil movement better than a monolithic pour, because the joints flex instead of cracking. The catch is that “properly built” part. On Fresno’s adobe clay, that means a deeper compacted base, separation from any post-tensioned slab, and drainage that moves water away from the clay. When our crew installs a Unilock driveway in Fresno, it’s designed for this soil, not for a generic California site. For a range on your specific driveway, call (936) 259-2607 for a free estimate.
Over 100 days above 90°F and UV peaks over 110°F fade and chalk unsealed color, especially on south- and west-facing exposures. Copthorne clay pavers are the most visible when they start to weather. Sealing with a product rated for this climate slows it significantly. We can also refresh older surfaces. Call (936) 259-2607 and we’ll take a look at your exposure and give you a straight answer on what sealing will and won’t do.
