Unilock Construction in San Bernardino, CA | Milpitas Construction
We install and repair Unilock segmental retaining walls and paver systems across San Bernardino, from pre-1950 bungalows near downtown to fire-rebuild lots up toward the 92407 foothills. The work here isn’t just laying block; it’s reading grade, drainage, and base prep for each specific site because what holds up on a flat west-side tract lot fails fast on a sloped foothill rebuild. Call (877) 752-4194 for a free estimate on Unilock paver driveways, patios, and retaining walls anywhere in the 92401, 92402, 92403, and 92404 ZIP codes.
Why San Bernardino Residents Choose Us for Unilock Service
San Bernardino has a construction reality most Inland Empire cities don’t: a large share of its housing stock dates to the 1940s through 1960s, single-story wood-frame and stucco-over-sheathing, with post-war tracts on the west and south sides and older bungalows near downtown. A lot of that work now needs foundation, drainage, and exterior upgrades, not new construction. That’s where we come in. We’re a full-scope general contractor offering Unilock in Highland and nearby areas, and we treat Unilock hardscaping as part of the larger site puzzle, not an isolated paver job.
Ken Stafford, our owner, grew up in construction and has spent over two decades working residential builds and remodels that hold up through soil shifts and seismic quirks. The Unilock work we do in San Bernardino gets the same scrutiny: we check grade before we quote, we inspect what’s under the existing surface before we tear anything out, and we spec materials by name so you know exactly what’s going into your home. We’re an independent contractor and are not authorized, sponsored, or endorsed by Unilock. That independence is exactly why we can be honest about what a failing paver field actually needs, which is usually a base and drainage fix, not a fresh layer of new units.

Common Unilock Construction Problems We Solve in San Bernardino
- Efflorescence blooming on Brussels Block and Beacon Hill pavers. San Bernardino’s infrequent but intense winter rain pulls salts through a base that was never properly drained, leaving a chalky white film on the surface. We fix the drainage first, then address the staining so it doesn’t return with the next storm.
- Base failure and rutting on west-side and south-side post-war tract lots. Pavers laid directly over native sandy soil without compacted Class II base settle, shift, and develop low spots that pond after rain. We see this constantly on 1940s-1960s tracts in San Bernardino.
- Pisa2 retaining wall bulging or leaning on foothill lots. Near the 92407 foothill edges, sloped lots without correct geogrid and drainage aggregate behind the wall start to lean within a few seasons. Water pressure builds behind the wall during winter rains, and the wall loses the fight.
- Surface spalling and color loss on older Town Hall pavers. Years of hot, dry San Bernardino summer sun combined with Santa Ana wind abrasion wears down older pavers. Skipped sealers at install accelerate it, and we see the damage concentrated on south-facing exposures.
- Ponding driveways after winter storms. A heaved Brussels Block driveway that was laid without edge restraints or proper slope sends water toward the house instead of away from it. On older San Bernardino bungalows, that water ends up against a 1940s foundation.
Unilock Service in San Bernardino: What Local Conditions Mean for Your Equipment
San Bernardino couples some of the region’s oldest incorporated housing stock with a fire-rebuild corridor along the foothills, and that split shows up in nearly every Unilock project we scope. A paver driveway on a flat post-war tract near the west side often has to be designed around mature tree root zones and old service lines that no one mapped when the house went up in 1955. Meanwhile, a patio on a fire-rebuild lot up toward the 92407 foothill edges is a completely different job; same pavers, but now slope, drainage, and retaining-wall geogrid become the things that determine whether the work survives. Contractors working those foothill edges and the older blocks around downtown routinely deal with a split reality: fire-hardening rebuilds up high and 1940s wood-frame structural and drainage retrofits down low, often on the same crew’s schedule in the same week. A generic Unilock page won’t tell you that; a San Bernardino contractor who’s actually worked both sides of it will.
Unilock Models & Products We Service in San Bernardino
We handle Unilock’s core residential paver and wall systems: Brussels Block, Beacon Hill Flagstone, Pisa2 retaining wall, and Town Hall pavers. When a repair or extension has to tie into existing courses, we source genuine Unilock units with matching edge restraints and caps so the new work reads as one field, not a patch job. For base aggregate, geogrid, and polymeric joint sand, we use proven aftermarket materials where they outperform the OEM option. Our honest stance across San Bernardino is that a settled or heaving paver field is a base and drainage problem first, so we fix the subgrade before replacing any surface units. We’re an independent Unilock service provider; that means our Unilock sales & service work is driven by site conditions, not a manufacturer’s catalog.

AfterUnilock Service Pricing in San Bernardino
What drives the cost isn’t usually the Unilock units themselves; it’s what’s underneath. A flat lot with decent drainage is a straightforward job. A sloped foothill lot in the 92407 corridor that needs retaining-wall geogrid, extra drainage aggregate, and imported compacted Class II base is a different animal. Here’s what Unilock in Rialto and San Bernardino hardscaping runs:
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Concrete Driveway Installation | $4,500 – $12,000 |

FAQs – Unilock Construction in San Bernardino
Because the base underneath was never built for how San Bernardino drains. The city’s winter rain is infrequent but intense, and when it hits pavers laid over native sandy soil without compacted Class II base, water saturates the subgrade, the soil shifts, and the surface heaves and ponds. The fix is tearing out the failed base, compacting proper aggregate, and setting slope away from the house. Call (877) 752-4194 for an exact diagnosis and quote.
Yes, we can. We source genuine Unilock units in the current production run, then blend them with the existing field so the repair reads as intentional rather than patchy. Color and surface wear from two decades of San Bernardino sun and Santa Ana wind means a perfect match isn’t possible, but a well-blended one is. We’ll tell you what’s achievable before we start.
We design for water first. A Pisa2 wall on a slope fails when water builds up behind it, so we install drainage aggregate behind the wall, add geogrid reinforcement at the correct layers, and make sure the base course is set on compacted, level material. The wall is the visible part; what’s behind it is what keeps it standing through a wet San Bernardino winter.
It depends on the scope. Simple paver patios typically don’t trigger permits in San Bernardino, but driveways, retaining walls over a certain height, and work that changes site drainage often do. We handle the permit side as part of the project and make sure the work passes inspection the first time. Call (877) 752-4194 and we’ll tell you what your specific lot requires.
Not immediately. New pavers need the polymeric joint sand to fully cure and the surface to be clean and dry before sealing. In San Bernardino’s hot, dry summers, that usually means waiting a few weeks after install, then sealing on a day when surface temps aren’t scorching. We schedule sealing as a separate pass so the paver surface is ready when the sealer goes down.
