Unilock Construction in San Dimas, CA | Mason Remodeling Co West Covina
Unilock construction service in San Dimas means building paver patios, driveways, and walls that can handle steep foothill grades, decomposed granite soil, and the occasional winter downpour that sends water moving fast down-slope. We’re Mason Remodeling Co West Covina, an independent Unilock service provider and General Contractor in San Dimas with years of hands-on work on hillside properties from Foothill Boulevard north to the San Gabriel Mountain edge. What makes our Unilock work different in San Dimas is that we rebuild bases and drainage first, then lay the pavers second. Call (707) 760-7579 for a written estimate on your project.
Why San Dimas Residents Choose Us for Unilock Service
Unilock pavers are tough, but they’re only as stable as what’s underneath them. That’s the part most installers rush. We don’t, because Isaac Pruett, our owner, learned the slow way to build on shifting ground, starting at Los Angeles Trade-Technical College and then across decades of jobs throughout the San Gabriel Valley. He’s seen what decomposed granite does to a shallow base after two or three rainy seasons. Our crews install and repair Unilock products across San Dimas with that hillside reality in mind every single time.
We carry genuine Unilock replacement units sourced from local dealers so color blends and textures match, even on pavers that have been sun-faded for ten years. And because we work throughout San Dimas service area regularly, we know which part of town sits on granite and which sits on older alluvial fill. That local knowledge shows up in the base we build and the drainage we route. You should know what you’re getting before we ever pick up a tool.

Common Unilock Construction Problems We Solve in San Dimas
These are the failures we see most often in San Dimas, and each one connects to something specific about this city’s terrain or climate:
- Edge spalling on Brussels Block. Brussels Block is a classic tumbled paver, but on San Dimas hillside lots the edges chip and flake when the base shifts under the pavers. The pavers grind against each other, and the edges go first. Fixing the surface without rebuilding the base just means you’ll see the same damage again in a couple of years.
- Base erosion near old cast-iron drains. Homes built before 1980 in San Dimas frequently have corroded cast-iron drain lines. When those fail underground, water saturates the paver base and washes it out. You’ll see a sunken depression that grows after every rain. It’s a drainage problem wearing a paver costume.
- Joint sand loss and weed intrusion. San Dimas swings from scorching dry summers to heavy winter rain. The sand between pavers dries and blows out in summer, then rain pushes the rest out in winter. Weeds follow. Polymeric sand helps, but it has to be applied at the right moisture level and re-sealed on schedule.
- Efflorescence on Richcliff and Beacon Hill Flagstone. The white chalky bloom isn’t a paver defect. It’s mineral salts from hard water deposits rising through the paver surface. San Dimas water carries a heavy mineral load, and lighter-colored pavers like Richcliff and Beacon Hill Flagstone make the efflorescence obvious.
- Sinking corners on hillside patios. When a patio sits on a slope, one corner almost always takes more water than the others. Over time that corner settles, and you get a visible dip. Leveling the pavers alone misses the point; the subgrade under that corner has to be rebuilt and compacted properly.
Unilock Service in San Dimas: What Local Conditions Mean for Your Equipment
Here’s the thing most paver contractors from flatland cities don’t understand until it’s too late: San Dimas hillside homes north of Foothill Boulevard sit on decomposed granite that shifts under freeze-thaw cycles and saturates unevenly during winter rains. A shallow gravel base that works perfectly on a flat lot in Glendora or La Verne will creep and settle on a San Dimas slope within one or two seasons. The pavers don’t fail. The ground under them moves.
That’s why we build bases differently for hillside work. We over-excavate, install geotextile fabric to separate the native granite from the aggregate, and compact in lifts so the base holds its shape under load. On steeper lots, we add subsurface drainage to move water away from the base before it can erode anything. This is the difference between a patio that looks great for one summer and a patio that still drains correctly and holds level a decade later. If your property is in the foothills north of Foothill Boulevard, this matters more than the paver color you choose. We’re an independent Unilock service provider, not a manufacturer affiliate, so we can rebuild the base the way your slope actually needs it rather than the way a spec sheet assumes it.
Unilock Models & Products We Service in San Dimas
We work with the full range of Unilock product lines most common on San Dimas properties. Unilock sales & service starts with knowing each product’s failure points, and here’s what we see:
- Brussels Block: The workhorse tumbled paver. We stock replacement units locally for color-matched repairs.
- Richcliff: The taller, more contemporary paver. Great for San Dimas patios, but it shows efflorescence more visibly than darker lines.
- Beacon Hill Flagstone: A flagstone-look paver with wide joints. Joint sand choice matters more here than on tighter-jointed products.
- Lineo Dimensional Stone: The linear, modern option. Cuts cleanly for borders and steps, and we keep it in stock for San Dimas turnaround.
For structural repairs we don’t surface-patch. We rebuild bases with proper aggregate, compacted in lifts, with geotextile where the native soil is unstable. That’s the only way a repair outlasts the next rainy season.

FAQs – Unilock Construction in San Dimas
My Unilock paver patio on a San Dimas hillside is sinking in one corner – is it just the pavers or should I check my drainage?
If one corner is sinking on a hillside San Dimas lot, check the drainage first. Water running down-slope concentrates at the lowest corner, saturates the base, and washes fine material out from under the pavers. Leveling the pavers without fixing the drainage just resets the clock on the same problem. Call (707) 760-7579 and we’ll assess the slope, drainage, and base before quoting the repair.
Can you match my existing 15-year-old Unilock Richcliff pavers when extending the patio?
Yes, in most cases. We source genuine Unilock replacement units from local dealers and match by color blend and texture, not just by product name. Fifteen years of San Dimas sun fades pavers, so we’ll pull from multiple pallets to blend the old with the new. An exact match isn’t always possible on discontinued color blends, but we’ll show you samples on-site before you commit.
Why are my Unilock Brussels Block pavers flaking on the edges after a few San Dimas winters?
Edge spalling on Brussels Block usually means the pavers are moving against each other. The base beneath them is shifting, and the pavers’ edges grind together under foot and vehicle load. On San Dimas hillside lots, decomposed granite soil is the usual culprit. The fix is base stabilization, not just replacing the chipped pavers. Call (707) 760-7579 for a free slope and base assessment.
Do I need a different paver base for a driveway in San Dimas than what a flatland installer would use?
Yes, and this is the biggest difference between a San Dimas-specific install and a generic one. Hillside loads, decomposed granite subgrade, and concentrated storm runoff require deeper excavation, geotextile fabric, and compacted aggregate in lifts. A shallow base that’s fine in flatland cities will creep and settle on a San Dimas slope. We build the base for your grade, not for a generic spec sheet. Get a written quote at (707) 760-7579.
My patio pavers have white chalky stains – is that from the hard water in San Dimas?
Most likely yes. The white bloom is efflorescence, mineral salts from hard water that rise through the paver and crystalize on the surface. San Dimas water carries a heavy mineral load, and it shows up most on lighter Unilock colors like Richcliff and Beacon Hill Flagstone. It’s cosmetic, not structural, and it can be cleaned, though it may return over time. If you’d like us to take a look and recommend a cleaning approach, call (707) 760-7579.
