Unilock Construction in La Verne, CA | San Bernardino Contractors
We install and repair Unilock hardscaping across La Verne, from paver patios to segmental retaining walls. The thing that separates our Unilock work here from a flat-lot city is simple: La Verne’s foothill slopes and expansive soils demand drainage and base engineering before the first block gets set. San Bernardino Contractors is an independent Unilock installer, which means we spec the system your slope actually needs, not whatever happens to be on the yard display. Call (855) 473-5620 for a free estimate on any Unilock project in La Verne.
Why La Verne Residents Choose Us for Unilock Service
Ruben Castillo, our owner, got his start framing garages and reroofing houses with his uncle on the Westside of San Bernardino, and he’s carried that hands-on education through two decades of Inland Empire construction work. That background matters when you’re building with Unilock on a La Verne hillside. We don’t hand off your paver job to a separate hardscape crew. We’re the general contractor who understands how the retaining wall ties into the foundation drainage, how the patio grade affects water moving away from the house, and what happens when a slope gets a heavy winter rain on compacted base that wasn’t prepped right.
Because we manage Unilock sales & service alongside roofing, windows, kitchens, and ADUs, we see the whole property rather than one trade’s slice of it. One contractor, every phase. When a patio needs to tie into a downspout reroute or a retaining wall has to clear a foundation repair, that’s our scope. We use genuine Unilock wall units and edge restraints, but we’ll upgrade the geogrid and filter fabric where the site outruns what a kit provides. You pick the brand, we handle the build.

Common Unilock Construction Problems We Solve in La Verne
- Bulging Unilock Pisa2 and Estate Wall retaining walls. We regularly see walls on La Verne foothill lots that were built on footings sized for flat ground. The original install lacked proper grid tie-backs or drainage stone, so after one or two wet winters the wall face starts leaning and bulging out. Repair means rebuilding from the base, not patching the face.
- Brussels Block driveway settlement at the apron. On graded foothill driveways, water sheets off the slope and runs under the compacted base at the street apron. The pavers settle, rut, and the edge restraint fails. We fix the drainage path first, then reset the base and pavers so the problem doesn’t come back every winter.
- Richcliff efflorescence and hairline cracking after summer heat. La Verne’s July through September heat cycles are hard on textured pavers when the polymeric sand was installed over a base with too much moisture or the wrong aggregate. We see whitish efflorescence and fine cracks that trace back to prep, not the block itself.
- Permeable paver systems clogged with decomposed granite runoff. Uphill lots shed fine sediment and DG into permeable Unilock installations. The voids fill, infiltration dies, and water pools against the foundation. We rebuild with proper filter fabric and clean aggregate separation so the system actually drains.
- Pooling water on paver patios after winter rains. Foothill lots with 1950s-era slab foundations often have patios that were poured flat with no positive grade. When the winter rains hit, water stands. We regrade and set Unilock pavers on a base sloped to move water away from the house.
Unilock Service in La Verne: What Local Conditions Mean for Your Equipment
Here’s the reality about La Verne that flat-lot Pomona and Claremont rarely deal with. Much of the housing stock in the foothill neighborhoods sits on expansive soils that move with moisture, and the original 1950s and 60s foundations were never engineered for that movement. When those soils shift, hardscape built on top of them shifts too. That means a Unilock retaining wall or paver patio in La Verne has to be designed around drainage and soil movement first. In the Old Town area off Bonita Avenue, where lots are tight and homes predate modern grading codes, we’ve excavated behind failing walls and found no filter fabric, no weep stone, and grid that was never properly tensioned. The block was fine. The engineering underneath was the problem. Ruben Castillo’s crew rebuilt one such Pisa2 wall on a sloped Old Town lot by excavating to sound soil, resetting the base with compacted aggregate and filter fabric, adding grid tie-backs, and capping it with a Richcliff-topped patio that now sheds water away from the house. That’s the difference between a patch job and a repair that holds. If it’s not built right the first time, you’re just paying for it twice.
Unilock Models & Products We Service in La Verne
We work with the full Unilock line that makes sense for La Verne properties. Brussels Block is our go-to for driveways and patios that need a classic tumbled look with dimensional consistency. Beacon Hill gives you a more dressed, stone-like surface that reads well on Spanish-style and ranch homes from the mid-century stock. Richcliff carries a textured, flagstone-like face that suits Old Town and hillside homes where the hardscape needs to blend with the natural slope. For retaining walls, we use the Unilock Estate Wall and Pisa2 systems, and we stock matching caps, edge restraints, and paver units locally so we’re not ordering from a catalog and waiting two weeks on a La Verne driveway repair. We use genuine Unilock block, but we’re frank about where a kit’s geogrid or base spec falls short on a La Verne grade. We substitute commercial-grade geogrid, filter fabric, and compacted aggregate when the slope demands more than the kit provides. That’s the independent installer advantage.

AfterUnilock Service Pricing in La Verne
Expect the scope of a La Verne hillside project to drive cost more than the paver line you pick. A flat-lot patio in Upland might be a straightforward base-and-set job. A sloped Old Town lot needs excavation, possibly a retaining wall, drainage work, and engineered base prep. That’s the difference between a $3,500 patio and an $11,000 one. Here’s what we tell La Verne homeowners:
| Unilock Project Type | Typical Range |
|---|---|
| Paver Patio Installation | $3,500 – $11,000 |
| Paver Driveway Installation | $7,000 – $18,000 |
| Driveway Replacement | $5,000 – $14,000 |

FAQs – Unilock Construction in La Verne
Yes, in most cases. La Verne’s expansive soils and sloped grades mean any retaining wall over about three feet should be engineered for the site’s soil bearing, drainage, and surcharge from the uphill side. We see failed walls on foothill lots all the time because the original install skipped grid tie-backs or undersized the footing. We pull a local permit and work with a structural engineer when the slope demands it. Call (855) 473-5620 to talk through your wall’s condition.
Yes, Unilock’s concrete pavers are designed for high-heat climates, but the install matters as much as the block. La Verne’s July through September heat dries out poorly mixed polymeric sand and causes hairline cracking on pavers set over a base with too much moisture at install. We prep bases for the heat and the winter rains, not just the day of install. If your existing pavers are showing heat-related efflorescence or cracking, call (855) 473-5620 for a free assessment.
Because the patio was installed flat, without enough positive grade to shed water away from the house, and often without a proper drainage layer under the base. On La Verne’s foothill lots, uphill runoff adds to the problem. We regrade the base, add filter fabric and drainage aggregate, and set the pavers to slope water off the hardscape instead of holding it. Call (855) 473-5620 for an exact quote on a patio drainage fix.
Usually yes. Brussels Block, Beacon Hill, and Richcliff are all current Unilock lines with consistent color blends, so matching a mid-century home’s existing hardscape is often a matter of ordering the same product and blending the new material with the old over a few rows. For walls, we can match cap and face units, though older installations may have faded. Bring us a photo and we’ll tell you what’s matchable. Call (855) 473-5620 and we’ll come out to La Verne to look.
Most Unilock driveway installs in La Verne run seven to ten working days, longer if we’re rebuilding a failing base, adding drainage, or replacing a retaining wall at the same time. Winter rain delays are real on foothill sites, so we build that into our schedule. Call (855) 473-5620 for a free estimate with a timeline specific to your property.
