Unilock Construction in Fontana, CA | Pinecrest Contractors
We’re Pinecrest Contractors, and we provide independent Unilock paver and wall installation, repair, and replacement across Fontana. The short version: we’re not a Unilock dealer or authorized installer, we’re a full-scope general contractor who has built with Unilock products for years and knows exactly how they behave in Fontana’s Cajon Pass wind corridor and expansive soil. That local knowledge matters more than a manufacturer logo on a van. Call (855) 702-1622 for a free estimate on any Unilock project in Fontana.
Why Fontana Residents Choose Us for Unilock Service
Most Fontana paver jobs don’t fail because of the pavers. They fail because of what’s underneath them. Gil Rourke, our owner, learned that lesson early, back when he was framing through Santa Ana gusts and watching compacted bases get undermined by soil that had other ideas. We approach every Unilock installation in Fontana as a soil and wind problem first, a paver problem second. That’s why we over-excavate, compact Class II base in lifts, and spec heavier edge restraint than you’d see on a standard install further west. We also work with Unilock products the way a mechanic works with a specific engine family: we know the Brussels Block tumbled profile, the Beacon Hill flagstone textures, the Pisa2 permeable joints, and the Estate Wall block geometry. Our parts sourcing follows the same logic. We use genuine Unilock units and OEM joint sand and geogrid when lead times and site conditions allow, and we spec compatible aftermarket base materials and polymeric sands when that’s the smarter build. Unilock sales & service is a big part of what we do, but the real value is knowing what to put under the paver.

Common Unilock Construction Problems We Solve in Fontana
- Wind-driven grit abrasion on exposed Brussels Block. Fontana sits in the Cajon Pass wind path, and a Santa Ana event can sandblast a driveway surface over a few seasons. The tumbled texture of Brussels Block hides some of it, but the discoloration and micro-pitting eventually show. We clean, re-sand, and seal, or re-lay if the surface has gone too far.
- Differential settlement and lippage on slab-on-grade sites. Much of northern Fontana’s 92336 housing stock is concrete slab-on-grade with stucco over wood frame. When a paver driveway or patio is installed over disturbed original subgrade, the expansive Inland Empire clay moves. We see lippage in Beacon Hill installations most often because the flagstone profile makes any vertical shift obvious.
- Leaning or bulging Estate Wall sections. Segmental retaining walls without geogrid reinforcement in Fontana’s wind corridor get pushed around by seasonal gust cycles and soil movement. A wall that looks fine in May can show a visible lean by October. We pull the affected courses, add reinforcement, and re-stack.
- Pisa2 permeable joints clogged with warehouse dust. Fontana’s industrial and logistics development throws fine silt into the air near active tilt-up sites. Permeable pavers eat that dust. Joints pack up, infiltration drops, and standing water appears where it shouldn’t. We restore the joint system and correct any drainage fall issues.
- Heaved driveways in the older 92335 and 92337 ZIPs. The mid-century stucco tract homes in south Fontana sit on soils that have been settling for sixty years. When original paver bases were never properly compacted, freeze-thaw isn’t the culprit here, it’s wet-dry cycling in clay. We re-excavate and rebuild from the subgrade up.
Unilock Service in Fontana: What Local Conditions Mean for Your Equipment
Fontana sits directly in the Cajon Pass wind corridor, and that’s the single biggest factor in how Unilock work has to be engineered here. The same Brussels Block driveway built in Rancho Cucamonga, Eastvale, or even areas served by our Rialto Unilock service will experience a fraction of the wind loading we deal with on every Fontana job. What does that mean in practice? Edge restraint has to be buried deeper, typically into a concrete collar, because sustained gusts push against the paver field and the perimeter wants to wander. Base compaction has to be over-specified, usually 6 to 8 inches of Class II instead of a standard 4, because Fontana’s clay subgrades expand and contract through the dry-wet cycle and will telegraph movement through a thin base. And on retaining walls, we don’t skip geogrid. A two-foot Estate Wall in Rancho might get away without it. A two-foot wall off Sierra Lakes Parkway, where wind funnels between the tract homes and the golf course, absolutely will not. The right material in the right place, that’s where the job starts. In Fontana, the right place is wind-braced and deep-compacted.
Unilock Models & Products We Service in Fontana
We work across the Unilock hardscape catalog, but the four lines we see most often in Fontana are Brussels Block, Beacon Hill, Pisa2, and Estate Wall. Brussels Block is the workhorse tumbled concrete paver that shows up on a lot of the 1990s and 2000s north-side driveways. Beacon Hill skews toward patios and walkways where homeowners wanted a flagstone look without the stone price. Pisa2 is the permeable option, and Estate Wall handles the segmental retaining work on sloped lots and planter beds. On the parts side, we stock common replacement units locally so a repair doesn’t stall while something ships from a regional distributor. When we do the repair-versus-replace math, we’re honest about it. A driveway that’s moved in one corner is usually a localized re-lay and re-compaction job, not a full tear-out. We’ll tell you that, even when a full replacement would bill higher.

FAQs – Unilock Construction in Fontana
Yes, if the base and edge restraint are built for it. Unilock pavers themselves are dense and heavy, but the wind doesn’t lift the paver, it pushes the field and stresses the perimeter. In Fontana we specify concrete edge collars or deeply buried aluminum edging, plus 6 to 8 inches of compacted Class II base. That combination holds up to seasonal gusts far better than the standard 4-inch base installs you see in cities off the Pass. Call (855) 702-1622 to have us look at your specific site.
Almost always, the original base was too thin or undercompacted for the expansive clay underneath. The north-side 92336 subdivisions were built fast on slab-on-grade pad sites, and when a paver contractor lays on top of disturbed subgrade without proper compaction, the clay’s wet-dry cycle pushes up through the base and the pavers move. We fix it by re-excavating, compacting Class II in lifts, and reinstalling with geotextile fabric. It’s a repair we do regularly off Sierra Lakes Parkway and throughout the 92336 ZIP.
Yes. Pisa2 is the right call for properties near Fontana’s active logistics and warehouse developments where drainage and dust management matter. The catch is maintenance: fine construction silt from nearby tilt-up and truck-yard activity will clog the permeable joints faster than normal, so you’ll need joint restoration more often. We install Pisa2 with that reality in mind and can set up a maintenance schedule so the system keeps infiltrating. Call (855) 702-1622 for a site assessment.
A Unilock paver driveway in Fontana typically runs $7,000 to $18,000 depending on square footage, access, base depth, and whether we’re removing an old concrete slab or building fresh. A standard two-car driveway on flat ground in 92335 lands on the lower end. A long, wind-exposed driveway in 92336 with poor truck access and extra base requirements pushes higher. The estimate is free and we put every line item in writing.
Yes, we repair leaning Estate Wall sections regularly. The fix usually involves pulling the affected courses, checking the base and drainage, adding geogrid reinforcement where it was skipped, and re-stacking with OEM units. In Fontana’s wind corridor, walls that were built without reinforcement lean first. We address the geogrid deficiency rather than just re-stacking and hoping. Call (855) 702-1622 and we’ll inspect the wall.
