Tremron Construction in Sunnyvale, CA | Rowan Construction Group Sunnyvale
We provide independent Tremron paver installation and repair across Sunnyvale, from Birdland teardowns to Lakewood Village ADU additions. The one thing that makes our Tremron work here different: we’ve learned to engineer the base for Bay clay’s shrink-heave cycle before we set the first paver, because a Tremron driveway that looks perfect in October can be rutted by March if the sub-base was guessed instead of calculated. Call (650) 405-3637 for a free written estimate - we deliver the full line-item price before anyone picks up a shovel.
Why Sunnyvale Residents Choose Us for Tremron Service
We’ve been setting Tremron pavers in Sunnyvale since the first wave of Lakewood Village teardowns started in earnest around 2015. Grant Rowan, who grew up in Beverly Hills and picked up his first framing hammer before he could drive, trained in construction technology at Santa Monica College - structural load calculations, blueprint reading, site safety - and he still references those fundamentals when scoping a Tremron job today. That means our crews don’t just know the paver lines; we know what the soil report should say before we bid.
We stock Tremron’s current Classic and Signature collections locally, along with matching caps and borders for the Mega Olde Towne and Bristol Valley lines. When a discontinued color run forces a substitution, we use quality aftermarket pavers of the same thickness and joint spec for hidden or peripheral areas only, and we tell you exactly where before we start. Under Clause 1 of the Haven Standard, the price is written before anyone starts - material costs, labor hours, and subcontractor scope listed separately so you know where each dollar goes. Our Tremron sales & service covers everything from a single patio repair to full driveway replacement on a new custom build.
We’ve delivered more than 4,000 projects since 2007, every one with a written price before work started and a documented photo record when the crew left. The 365-Day Done Right Promise is printed on every page, not hidden behind an asterisk.
Common Tremron Construction Problems We Solve in Sunnyvale

- Efflorescence bloom on new Tremron installs. The white chalky film that shows up after Sunnyvale’s first wet winter is almost never a defective paver. It happens when base rock or bedding sand gets contaminated with soluble salts during construction, then wicks to the surface through the joints. Our crews keep base materials covered during the dry season and flush the bedding course before setting pavers.
- Edge spalling and surface pitting from clay heave. The expansive Bay clay under Sunnyvale’s 1950s tracts shrinks to dust by September and swells with winter rain. Tremron pavers locked in a rigid edge restraint without an engineered base rock against each other under vehicle traffic. We specify geogrid-stabilized base and flexible edge detailing on every driveway.
- Settlement and rutting at driveway aprons. The corners and transition zones where a Tremron driveway meets the street take the worst of the clay’s seasonal movement. A thin base - or a base that wasn’t deepened per engineer spec - fails in two to three seasons. We dig to engineered depth, not to what looks reasonable.
- Mortared border and step units cracking at the joint line. On post-tensioned slab homes common in late-1970s and 1980s Sunnyvale tracts, the paver apron can’t be tied rigidly to the structure. We cut the structural tie, float the paver field, and use expansion joints at the building line.
- Color mismatch on patch and addition work. Tremron runs color in lots, and Sunnyvale’s sun exposure fades pavers unevenly. We source from current stock when possible, and when matching a weathered field, we blend new units across the repair zone rather than creating a visible patch.

AfterTremron Service in Sunnyvale: What Local Conditions Mean for Your Equipment
Sunnyvale’s permit office requires a separate Title 24 energy compliance report and CalGreen Tier 1 documentation even on modest site work and additions. A Tremron paver driveway or patio tied to a new ADU or Sunnyvale Kitchen Remodeling or teardown-rebuild can stall for weeks if the solar-ready roof penetrations, EV-ready conduit, and water-conservation fixture certifications aren’t packaged correctly in the initial submittal. Out-of-county crews hit this wall constantly - they pull a permit in Santa Clara or San Jose without the CalGreen layer, assume Sunnyvale works the same way, and watch their project sit in plan check while the clay season shifts. We’ve pulled permits through Sunnyvale Building Division enough times to know the submittal package by heart. On a recent Birdland ranch teardown, the homeowner wanted a Tremron Olde Towne driveway and walkway leading to a new ground-up build. Our crew found the old concrete apron had been pinned to a slab that was heaving on Bay clay. We cut the tie to the structure, dug to a deepened engineered base with geogrid, set the Tremron pavers on a stabilized bedding course, and the driveway has stayed level through two wet winters and two dry summers since. Measure it twice, write it down, then build it.
Tremron Models & Products We Service in Sunnyvale

We work with Tremron’s full residential hardscape line. The Classic and Signature paver collections cover most Sunnyvale driveway and patio applications; we size the unit thickness to the load - 60mm for pedestrian patios, 80mm for vehicle traffic. Mega Olde Towne and standard Olde Towne pavers handle the traditional aesthetic requests we see in Lakewood Village and the Birdland area. Bristol Valley gives a cleaner, more contemporary face for the modern custom builds replacing teardowns. For grade changes and retaining needs, we build with Tremron’s Estate Wall and AB Classic retaining wall lines, always with proper drainage aggregate behind the wall to handle the clay’s hydrostatic pressure. Cambridge Cobble and Tuscany pavers round out the options for courtyard and pool-deck work. We source Tremron OEM pavers, wall units, and matching caps and borders for additions and repairs, and we match color and finish lot when we can. Our Sunnyvale service area covers the full range from repair to new installation.

FAQs - Tremron Construction in Sunnyvale
Yes, when the base is engineered for it. The pavers themselves are dense concrete units rated for freeze-thaw and load; the failure mode is almost always base movement, not paver degradation. We specify deepened, compacted base with geogrid stabilization on Sunnyvale’s clay soils, and we separate the paver field from rigid structural ties. Call (650) 405-3637 and we’ll review your soil conditions at no charge.
Yes, but the paver apron must be structurally independent. We locate the post-tension cables with GPR scanning before any penetration, cut the tie between slab and paver field, and detail expansion joints that let the clay move without cracking the border. The slab stays intact; the pavers float above it on their own base. Call (650) 405-3637 to schedule a site evaluation - estimates are free.
Only if it’s part of a permitted addition, ADU, or new construction. A standalone patio replacement on existing grade typically doesn’t trigger Title 24, but when the patio is tied to a new ADU or teardown-rebuild, the CalGreen Tier 1 package must include site work documentation. We package the paver spec, permeability calculations, and any required water-conservation notes with the primary permit submittal so nothing stalls in plan check. Call (650) 405-3637 and we’ll confirm what your specific project requires.
No. The white film is efflorescence, calcium hydroxide migrating to the surface through moisture paths in the joints. It’s common on new installs in Sunnyvale’s wet-winter/dry-summer cycle when base materials weren’t kept clean during construction. We can diagnose whether it’s active efflorescence that will exhaust itself or a chronic moisture problem from poor drainage, then recommend the right treatment. Call (650) 405-3637 for an exact assessment - estimates are free.
We match from current Tremron OEM stock when the original lot is still available. When a color run has been discontinued, we source quality aftermarket pavers of identical thickness and joint spec for hidden or peripheral areas, and we show you the blend plan before ordering. Sunnyvale’s sun exposure means even matched lots can read differently until weathering catches up; we blend new units across the repair zone to minimize the visible transition. Call (650) 405-3637 and we’ll photograph your existing field and check availability.
