Unilock Construction in Fontana, CA | Square One Builders
We provide independent Unilock installation and repair across Fontana, from paver driveways to U-Cara retaining walls, and the one thing that separates our work here is base prep. Fontana’s north side sits on former dairy and agricultural land with fill soils that move differently than what inland installers expect, and shallow bases fail fast. We’re a full-scope general contractor, not a Unilock dealer, so our loyalty is to the excavation, compaction, and edge restraint that survives Fontana heat and Santa Ana wind. Call (877) 688-9930 to schedule a free estimate.
Why Fontana Residents Choose Us for Unilock Service
We’ve torn out and rebuilt enough sun-cooked pavers and shifted retaining walls in Fontana to know how Unilock systems actually fail here – and it’s rarely the paver itself. It’s the base. Brent Calloway, our owner, spent years doing ground-level work before Square One Builders existed: hauling material, reading plans, asking questions until the answers made sense. That instinct carries into every Unilock job we take. We spec genuine Unilock profile units and matching color series when a repair needs to blend, and we use quality compatible polymeric sand, edge restraints, and base aggregate where OEM equivalents don’t exist. We’re local to Fontana and the surrounding Inland Empire, which means we’re not guessing at soil conditions from a satellite office two counties away. You get one contractor accountable for the excavation, the base, the pavers, and the finish – Unilock sales & service handled properly from the ground up.

Common Unilock Construction Problems We Solve in Fontana
- Efflorescence bloom on Brussels Block. Fontana’s hard summer irrigation cycles plus inland water chemistry push mineral salts to the surface of concrete pavers, leaving a white haze that won’t rinse off with a garden hose. We identify the source, clean the bloom properly, and adjust the joint sand and drainage so it doesn’t return in three months.
- Polymeric sand joint failure and paver migration. Driveways in Fontana take real loads – trucks, RVs, boat trailers – and when summer heat expands the slab underneath, joints open and Santa Ana-driven grit works pavers loose. We see this constantly on older southern Fontana homes where driveways were poured decades ago over compacted fill that has since settled.
- Base and edge restraint failure on sloped lots. The north side of Fontana has real grade changes. When runoff concentrates along the low edge of a patio or driveway, a shallow base and rusting steel edges heave and lip. We rebuild with deeper aggregate, proper compaction, and edge restraints that hold under water and heat.
- UV fading and surface dulling on colored pavers and U-Cara wall units. The Inland Empire sun is relentless, and dust from the I-10/I-15 corridor settles into paver surfaces, dulling color. We restore what can be restored and tell you straight when a paver series should have never been spec’d for full western exposure.
- Shifting U-Cara retaining walls on former dairy-land fill. Walls built on uncompacted or poorly drained fill lean and crack within a few years. We rebuild with proper drainage behind the wall, geogrid where needed, and a base that won’t settle unevenly.
Unilock Service in Fontana: What Local Conditions Mean for Your Equipment
Fontana’s north side is built on former dairy and agricultural land with fill and variable soils. That single fact changes how we prep every Unilock paver and U-Cara wall base here. Where an installer working sandy lots in parts of Riverside or San Bernardino might get away with a few inches of base, Fontana’s fill soils demand deeper excavation and compaction – sometimes significantly deeper – to prevent differential settlement. Add the Santa Ana winds off the Cajon Pass blasting that exposed soil while the crew is prepping, and you have a job site where cutting corners on compaction or leaving open trenches for a few windy days creates real failure risk. On a newer tract home up in the 92336 growth area north of the 210, our crew rebuilt a sun-heaved Brussels Block driveway that had been laid on shallow base over old dairy-land fill during a Fontana General Contractor project. We pulled the pavers, excavated deeper, re-compacted with proper aggregate, reset new edge restraints, and re-sanded. The joints have held through two Santa Ana seasons since. That’s not luck – that’s what proper prep looks like in Fontana.
Unilock Models & Products We Service in Fontana
We install, repair, and rebuild across the Unilock lines Fontana homeowners actually use. Brussels Block is the workhorse for driveways and walkways – we carry matching profile units for blend repairs. Beacon Hill and Townhall are common for patios where homeowners want a more structured, contemporary look. U-Cara retaining wall systems cover everything from low garden walls to structural terraces on sloped north Fontana lots, including Rialto Unilock service areas nearby. When a repair needs to match existing color, we source genuine Unilock units from the same series. Where a project calls for compatible polymeric sand, edge restraints, or base aggregate, we spec quality materials that won’t fail in Fontana heat. Our local stock of common profile units and joint materials means most repairs in Fontana get scheduled without waiting on a slow manufacturer backorder.

FAQs – Unilock Construction in Fontana
It means the soil under your patio may be fill that was never compacted to modern standards, and that fill settles unevenly under load and water. We excavate deeper than an installer would on native sandy soil, re-compact in lifts, and often add geogrid to the base before the pavers go down. Without that prep, you get lippage and joint failure within a few years. Call (877) 688-9930 and we’ll walk your lot and tell you what the soil is actually doing.
No, and that’s intentional. We’re an independent contractor, which means our recommendations are based on what your Fontana site actually needs – not on moving a dealer’s inventory. We install genuine Unilock products and source matching series units for repairs, but our first loyalty is to the base prep and finish grade that holds up here. Fontana service area work comes down to execution, not a manufacturer’s logo on our truck.
For paver and wall unit replacements, yes – we source genuine Unilock units from the matching series and color so the repair blends, whether it’s Glen Avon Unilock service or local Fontana work. For polymeric sand, edge restraints, and base aggregate, Unilock doesn’t manufacture those components, so we spec quality compatible materials that withstand Fontana’s heat and wind-driven grit.
We install and repair Brussels Block, Beacon Hill, Townhall, and the full U-Cara retaining wall system. If you have a different Unilock series, call us – if we can source matching units we’ll take the job, and if we can’t, we’ll tell you before you spend a dollar. We also cover Pedley Unilock service requests when materials are available.
Most spot repairs – joint re-sanding, paver replacement, edge restraint reset – are done in a single day. Full driveway or patio rebuilds with deep excavation and re-compaction on Fontana fill soils typically run three to six days depending on access and weather. We schedule around Santa Ana wind forecasts when possible, since open excavations and blowing grit don’t mix. Call (877) 688-9930 for a timeline on your specific project.
