Why Redlands Residents Choose Us for Unilock Service
Unilock pavers are a premium product, but a premium product installed over bad base is just an expensive problem. That is where we come in. Nelson Ibarra, the owner of Alder Contractors, grew up in the Willow Avenue corridor of Rialto and spent nearly three decades working homes and commercial buildings across the Inland Empire before founding this company. He learned the fundamentals at Chaffey College in Rancho Cucamonga, where the building technology program put tools in his hands rather than just theory in a notebook. What that means for your Redlands project is simple: we know what a proper paver base looks like, and we know what shortcuts create failures.
We also know paver repair honestly. When a Unilock patio in Redlands shows joint failure or a shifted field, we diagnose the actual cause before we quote anything. If spot repair with matching genuine Unilock units will hold, we say so. If the subgrade has failed and a rebuild is the only sound fix, we tell you that too. We do not sell a rebuild when a repair is the right answer. For more background on the systems we work with, see our Unilock sales & service page.

Common Unilock Construction Problems We Solve in Redlands
- Polysand joint failure on Brussels Block patios. Redlands sits in the hot, semi-arid citrus belt with summer temperatures regularly over 100°F, and the Santa Ana season pushes wind-driven grit across the Crafton Hills edges. That heat and grit breaks down polymeric joint sand, leaving joints open so pavers shift and ravel. We strip the old sand, re-joint with quality polymeric sand, and seal where it makes sense.
- Efflorescence and salt bloom on Richcliff and Beacon Hill Flagstone. Redlands’ dry climate, combined with irrigation overspray and shade, leaves pavers damp long enough for mineral salts to rise to the surface as white powdery film. It is cosmetic, but it looks wrong. We clean and, where needed, apply a breathable sealer that reduces re-bloom without trapping moisture.
- Paver edge and base erosion on driveways and walkways. Many Redlands properties sit over citrus-era brick, compacted native soil, or decades-old backfill that was never properly prepped. When the first heavy winter rain hits, the base underneath gives way and the edges start rutting. We pull the affected area, rebuild the base with compactable aggregate, and reset the units with fresh edge restraint.
- Faded or chipped Il Campo surfaces. Years of Inland Empire UV exposure dulls and chips the surface of older Il Campo pavers. When replacements are needed, matching weathered color is the real challenge, not finding the paver. We work from the existing field, source the closest genuine Unilock match, and blend repairs so they do not look like patches.
- Historic-district teardown surprises. When we pull up a failing paver run anywhere in the historic core, we are rarely surprised to find buried brick, redwood scraps, or loose fill a few inches down. That is the Redlands subgrade reality, and it changes how we quote and build. More on that below.
Unilock Service in Redlands: What Local Conditions Mean for Your Equipment
Redlands’ historic core around Smiley Heights and downtown sits over century-old citrus-era brick and original redwood foundations. That is a checkable fact about this city, and it changes paver work in ways Unilock in Highland or San Bernardino lots never present. A paver driveway or patio tear-out here often surfaces brick rubble, decomposed wood, and unstable fill at the same depth where a neighboring city would have clean soil or compacted subgrade. On a Smiley Heights property we pulled up a failing paver run and found the old installation sitting directly on citrus-era brick and loose fill, so we reset the subgrade, laid new base, and relaid the field in matching Unilock Brussels Block with fresh edge restraint. Fresh polymeric joint sand finished the job, and the patio has taken the last two Santa Ana seasons without a shifted unit. Any contractor can lay pavers on fresh fill. Redlands work means knowing what you are building over before you pour a single bag of base.
Unilock Models & Products We Service in Redlands
We install, repair, and service the full range of Unilock lines common across Redlands properties: Brussels Block, Beacon Hill Flagstone, Richcliff, and Il Campo. Each line has its own color palette, texture, and jointing behavior, and we know those differences well enough to match replacement units to a weathered field. For parts, we source genuine Unilock pavers and matching edge restraints so repairs blend rather than contrast. We do not substitute bargain paver brands on a repair unless you ask us to. For jointing we use quality polymeric sand, and for base we use compactable aggregate, not whatever is left in the yard. If you are looking at a full install rather than a repair, our Redlands service area page covers the scope of what we do across the city.

FAQs – Unilock Construction in Redlands
Yes, it can. Any exterior alteration visible from the street in Redlands’ designated historic districts can trigger a preservation review under the city’s historic preservation guidelines. It depends on the district, the scope, and whether the property has Mills Act status. We check historic status before we quote, and we pull permits when they are required. Call (833) 467-7020 and we will tell you whether your address falls inside a review zone.
The white powder is efflorescence, mineral salts rising through the paver from moisture, and the washed-out joints are polymeric sand that has degraded under Redlands’ heat and Santa Ana grit. Both are common in this climate. We can clean the efflorescence and re-joint with quality polymeric sand, and in most cases the repair holds for years. Call (833) 467-7020 for an exact quote on your patio or walkway.
In most cases, yes. We source genuine Unilock units in the closest available color match and blend them into the existing field. When the original pavers have weathered heavily, a perfect match is not always possible, but a well-blended repair reads as intentional rather than patched. We will show you samples before we order.
Generally, yes. Concrete slabs crack under thermal expansion and contraction, especially in the Inland Empire’s 100°F-plus summer cycles, and a single crack is expensive to hide. Paver driveways flex at the joints, so movement is absorbed without visible failure. The trade-off is that paver joints need periodic re-sanding, especially after Santa Ana seasons. For Redlands conditions, a properly built paver driveway is often the more durable choice.
If your property is in the downtown or Smiley Heights historic core, expect at least some citrus-era brick, decomposed wood from original redwood foundations, or unstable fill below the surface. It affects installation because that material does not compact reliably, so we remove it and build up a proper base before laying pavers. That is the difference between a patio that holds through the next decade and one that starts rutting after the first winter rain. Call (833) 467-7020 to schedule a site inspection and we will tell you what you are actually building over.
