Why Upland Residents Choose Us for Tremron Service
We’ve been working with Tremron products in the Inland Empire since 2007, long enough to know which paver finishes hold up against Upland’s 100°F-plus summer heat and which base preparations fail when the Santa Ana winds dump rain onto expansive foothill soils. Tremron sales & service through our operation means genuine Stonegate and Olde Town pavers sourced from authorized regional distributors, not gray-market substitutes that won’t color-match in two years.
Grant Rowan, our owner, trained at Los Angeles Trade-Technical College in framing and finish carpentry before building a general construction practice across Rancho Cucamonga and the surrounding cities. He’s put in renovation work near the Cucamonga Winery Historical Landmark corridor and developed a particular discipline around documentation: written scopes, itemized change orders, and photos at every stage. That habit carries directly into our Tremron work in Upland service area - when we quote a paver driveway or retaining wall, the price is flat, the scope is written, and the photo record shows you what we found and what we did.
Under Clause 1 of The Haven Standard, no work starts without a written price. Under our 365-Day Done Right Promise, if it’s not done right, we make it right. We don’t hand you a slogan; we hand you a terms page.
Common Tremron Construction Problems We Solve in Upland

- Efflorescence whitening on Tremron pavers - that chalky white film forms when moisture migrates upward through the base and carries soluble salts to the surface. In north Upland, expansive alluvial soils hold winter moisture for weeks after Santa Ana wind-driven rain events, making this more persistent here than on drier valley-floor sites. We strip the affected pavers, address the drainage, and reinstall with a properly sealed base.
- Edge spalling and surface scaling - Tremron pavers on south- and west-facing driveways and patios take the worst of Upland’s summer thermal expansion. Temperatures regularly exceed 100°F, and the daily swing between blazing afternoon sun and cool mountain air causes repeated expansion and contraction. We see this most on older installations where the original contractor skimped on joint sand or edge restraint.
- Joint sand erosion and paver shifting - without a properly compacted aggregate base, Tremron installations in Upland settle unevenly. The Cucamonga Fault Zone’s seismic movement accelerates this in foothill neighborhoods, where the ground doesn’t just sit still. We re-level with polymeric joint sand and geogrid reinforcement, not the cheap masonry sand that washes out in the first hard rain.
- Retaining wall block cracking or tilting - Tremron Highland Stone and Mega Olde Towne walls fail when the hillside behind them wasn’t engineered for Upland’s combination of expansive soils and slope drainage. In north Upland above 19th Street, we’ve rebuilt walls where the original installer ignored the soil report and skipped geogrid layers entirely.
- Base failure from undersized aggregate - mid-century tract homes across Upland’s 1950s-70s neighborhoods often have Tremron or predecessor paver installations laid over thin, poorly compacted bases. After decades of heat cycling and soil movement, the pavers rock and the joints open. We remove the failed section, re-grade with engineered base rock, and reinstall matching product.

AfterTremron Service in Upland: What Local Conditions Mean for Your Equipment
Here’s the Upland-specific reality that reshapes Tremron hardscape projects in ways a generic contractor page won’t tell you. In north Upland - roughly above 19th Street toward the foothills - the Cucamonga Fault Zone is a designated Alquist-Priolo Earthquake Fault Zone. That means any construction project involving excavation, grading, or retaining walls above a certain threshold requires a licensed geologist’s fault investigation report before the building department will approve permits. We’ve seen homeowners budget a straightforward paver patio or segmental retaining wall addition, only to discover mid-process that this study adds weeks and thousands of dollars to the timeline. This regulatory step simply doesn’t trigger in neighboring Ontario or Fontana on the valley floor, where the fault zone doesn’t extend. For Tremron retaining wall projects in the foothills, we flag this requirement in our initial site visit and written quote so you’re not surprised at permit submission. The expansive alluvial soils deposited by mountain runoff compound the challenge: they swell with moisture and shrink in drought, so the base beneath your Tremron pavers or wall block has to be engineered for both seismic settlement and soil volume change simultaneously. Near Euclid Avenue and the historic downtown, older homes with original stucco-over-wood-frame construction present a different puzzle - period-sensitive renovation work where modern hardscape meets century-old framing that may lack shear walls or seismic retrofitting.
Tremron Models & Products We Service in Upland

We work with the full Tremron product line on Upland service area projects, with genuine replacement stock sourced from authorized regional distributors for color and texture matching:
- Tremron Stonegate pavers - tumbled and tumbled antique finishes, used for driveways, walkways, and patios where a weathered appearance is specified.
- Tremron Olde Town pavers - tumbled finish, our standard recommendation for Upland driveways that see daily vehicle loading and thermal stress.
- Tremron Highland Stone retaining wall block - engineered for gravity and reinforced wall applications on Upland’s sloped foothill lots.
- Tremron Mega Olde Towne wall block - larger-scale unit for taller retaining walls and tiered hillside construction.
We don’t use aftermarket substitutes for color-matched repairs. When we source Tremron pavers, wall block, or caps, the batch comes from the same regional distributor pool that supplied the original installation, and we specify polymeric joint sand and geogrid reinforcement rather than cut-rate alternatives. For isolated spalling or settling, we repair and re-level; when the base has failed across a broad area, we quote replacement of the affected section with an honest assessment of why.

FAQs - Tremron Construction in Upland
Only if the project involves excavation, grading, or retaining walls above the threshold that triggers Alquist-Priolo review in the Cucamonga Fault Zone, which covers north Upland roughly above 19th Street. A simple paver overlay on an existing compacted base typically does not trigger this requirement. We verify permit requirements during our site visit and include any geologist study costs in the written quote if applicable. Call (909) 373-9612 and we’ll check your specific address.
Efflorescence - soluble salts carried to the surface by moisture migrating through the base - is the cause, and it’s particularly stubborn in north Upland where alluvial soils hold moisture after winter rain. The fix requires removing the affected pavers, improving drainage and base sealing, and reinstalling with polymeric joint sand that resists washout. Call (909) 373-9612 for an exact quote; estimates are free.
Temperatures exceeding 100°F cause thermal expansion in concrete pavers, accelerating joint sand breakdown and edge spalling on south- and west-facing surfaces. We specify polymeric sand and concrete edge restraints rated for Inland Empire thermal cycling, and we engineer the base to accommodate movement without transferring stress to the paver surface. Call (909) 373-9612 for an exact quote; estimates are free.
Yes - we source genuine Tremron Stonegate or Olde Town pavers from the same regional distributor network that supplied the original installation, matching color, texture, and thickness. When the original product line has been discontinued, we show you the closest current equivalent before any work proceeds. Call (909) 373-9612 for an exact quote; estimates are free.
Expansive soils that swell with moisture and shrink in drought, combined with inadequate base preparation and missing geogrid reinforcement, are the primary causes. In the Cucamonga Fault Zone, seismic settlement accelerates the failure. We rebuild with engineered base rock, specified geogrid layers, and drainage behind the wall per Tremron’s published specifications. Call (909) 373-9612 for an exact quote; estimates are free.
