Tremron Construction in Ontario, CA | Timberline Contractors
We provide independent Tremron paver and retaining wall installation and repair across Ontario, CA. The thing that makes our Tremron work different here is that we know how this city’s flat postwar lot grading and intense inland sun punish a paver base if it isn’t prepped right from the start. If you’re dealing with shifting pavers, white haze, or a bulging wall, call (866) 253-5808 for a free estimate.

Why Ontario Residents Choose Us for Tremron Service
Nelson Fung, our owner and general contractor, learned the trade at Los Angeles Trade-Technical College and spent years on remodels and commercial builds across the LA basin before founding Timberline Contractors. He grew up watching his grandfather debate tile prices at Saigon Plaza, which is probably where the materials obsession started. That obsession carries into how we approach Tremron work in Ontario and San Antonio Heights Tremron service: we treat every paver field as a base problem first and a surface problem second. We have laid and repaired Tremron pavers and walls across Ontario’s mid-century tracts and newer infill for years, and we source genuine Tremron units from regional Inland Empire distributors so courses, color, and thickness match existing runs. Nobody wants a patch that looks like a patch. We are an independent installer, not affiliated with or authorized by Tremron.

Common Tremron Construction Problems We Solve in Ontario
- Efflorescence and salt bloom. Ontario’s hard water, alkaline soil, and irrigation overspray drive a white haze into Tremron concrete pavers. The haze returns if the base and drainage aren’t corrected, not just cleaned. We address the moisture path before we treat the surface.
- Joint sand washout and paver shifting after winter rain. Flat postwar lot grading across Ontario’s older core means water has nowhere to sheet off. When intense winter rain hits, joint sand washes out and pavers start moving. We re-grade to positive slope and relay with quality polymeric joint sand.
- UV fading and surface spalling on older Tremron pavers. Inland Empire summers with intense UV break down the cap layer on pavers laid in the 1990s and 2000s, especially where no sealer was ever applied. We will tell you honestly when fading or spalling means replacement is the smarter spend over resealing.
- Retaining wall block settlement and bulging. Behind driveways on sloped infill lots in Ontario, we regularly find walls where the original installer skipped geogrid or proper compacted base. A bulging wall is a structural problem, not a cosmetic one. We rebuild with the correct reinforcement.
- Garage slab pooling. Runoff that pools against the garage slab in Ontario’s flat-lot neighborhoods soaks the base and destabilizes the paver field above. We fix the grading, not just the surface, so water moves away from the structure.
Tremron Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario sits at the junction of the 10, 60, and 15 freeways, and that freight position shapes Tremron work here in a way neighboring cities like Chino don’t experience. Palletized Tremron units arrive from regional yards on the same freight corridors that feed the city’s warehouse build-outs, so lead times and truck access to tight mid-century driveways are as much a scheduling problem as the install itself. On a 1950s tract home off Euclid Avenue, we tore out a cracked concrete driveway and set a Tremron Plaza Series paver field over a properly compacted Class II base with edge restraint. The flat lot grading had been pooling runoff against the garage slab, so we re-graded to a positive slope and used polymeric joint sand. After the next winter rain the water sheeted off instead of soaking the base. That’s the kind of fix Ontario’s older core demands.
Tremron Models & Products We Service in Ontario
We install and repair Tremron sales & service product lines including Old Towne Cobble tumbled pavers for driveways and walkways, the Plaza Series rectangular modular paver, Yukon and Riverstone retaining wall block systems, and the Bristol Valley and Capri collections for patios and pool decks. We source genuine Tremron units so color and thickness match existing runs, and we stock the decent base aggregate and polymeric sand that keeps those runs from failing in Ontario’s climate. When a paver field is sound but the base has failed, we lift, re-compact, and relay rather than push a full replacement. When the surface itself is done for, we tell you that too.

FAQs – Tremron Construction in Ontario
Yes. We source genuine Tremron units from Inland Empire distributors so courses, color, and thickness match the existing run. If your exact unit has been discontinued, we will show you the closest current option before any work starts. Call (866) 253-5808 for a free match-and-measure estimate.
The white haze is efflorescence, and it is driven by Ontario’s hard water, alkaline soil, and irrigation overspray drawing mineral salts to the surface. Cleaning alone won’t stop it. The base and drainage need to be corrected first, then we treat the surface. Call (866) 253-5808 for an exact diagnosis.
Flat postwar lot grading means water doesn’t sheet off on its own. Without a positive slope and edge restraint, runoff soaks the base and the pavers shift. We re-grade as part of the install so drainage moves away from the garage slab and foundation.
Yes, when installed over a properly compacted base with quality joint sand. UV will eventually fade any concrete paver in full inland sun, but a good sealer slows it. Santa Ana winds mostly stress surface debris and dry out joint sand, which a proper polymeric sand mix handles. Call (866) 253-5808 for a free estimate.
A bulging wall usually means the original install skipped geogrid or proper compaction. We can sometimes reset and reinforce the face, but if the block itself is cracked or the base has shifted, rebuilding is the honest answer. We will tell you which one applies to your wall. Call (866) 253-5808 for an assessment.
