Why Foster City Homeowners Choose Tremron Construction
As an independent Tremron installer, we handle paver driveways, patios, walkways, and retaining wall systems across San Mateo County, from Old Chicago brick pavers to the Mega Arbel and Tremron Stone series. Our Tremron in Foster City service focuses on one thing most contractors miss here: the lagoon-side lots with high groundwater and engineered fill that put real stress on paver bases and drainage. We are not affiliated with, authorized by, or sponsored by Tremron. We simply install and repair their products daily, and we know how they behave on Bay Area soil. Call (877) 752-3868 for a free estimate on any Tremron repair or installation in Foster City.
Why Trust Ashford Contractors for Your Tremron Construction?
Glen Mossier grew up in Foster City’s Marlin Cove neighborhood, where he spent summers watching lagoon-side homes get rebuilt after water damage. That taught him early that good construction is what keeps a house standing through decades of Bay Area weather. He trained in construction technology at Skyline College in San Bruno, learning framing, mechanical systems, and the materials science that actually shows up when a paver field starts failing. Over the past two decades, Glen has built a reputation across Foster City and Tremron in San Mateo for structural remodels and additions done without shortcuts. His crews get the subgrade and base compaction square before anything else goes in, because a paver is only as good as what sits under it.
Our team has pulled apart enough failed paver fields in Foster City to know the real culprit is almost never the Tremron unit itself. It’s the base. Clay-heavy fill soil, high water tables, and shallow compaction create movement that no paver can resist. We fix the base, not just the surface. “Build it right the first time, and you won’t be rebuilding it in ten years.”

Common Tremron Construction Problems We Fix in Foster City
- Efflorescence bloom on Old Chicago and Mega Arbel pavers. White salt staining appears when moisture moves up through the paver and evaporates, leaving mineral deposits on the surface. On Foster City lots near the lagoon and bay, the high water table pushes moisture upward constantly. If the base has no drainage plane or the joint sand has washed out, the bloom returns every winter. We fix the drainage, then the staining stops.
- Joint sand washout and paver shifting after heavy winter rain. Driveways without proper slope lose polymeric sand quickly. Once the joints empty, pavers start to drift under vehicle load. We see this on Foster City driveways where the original slope was set too shallow for the flat, low-lying terrain. Re-sloping the base and re-sanding with quality polymeric joint sand usually solves it.
- Edge restraint failure at driveway aprons. When a paver driveway meets the street apron, edge restraints take serious lateral force. If the old asphalt edge wasn’t removed or the restraint wasn’t set into concrete, pavers creep outward and the edge eventually collapses. We re-set edge restraints into concrete haunching at the apron, which stops the creep for good.
- Spalling and cracking on older Tremron units. Clay-heavy subgrade movement and tree-root heave can crack pressed-concrete pavers from underneath. Once a unit spalls, water gets in and the freeze-thaw-style damage accelerates. We replace individual units where possible, but if more than roughly a third of the field is compromised, full replacement is the honest recommendation.
- Retaining wall drainage failures on Tremron Stone and Stonewall systems. Keystone-style retaining blocks hold back soil and water. Without a proper gravel drainage column and filter fabric behind the wall, hydrostatic pressure builds and the wall leans or bulges. On Foster City’s flat lots, even low retaining walls collect groundwater. We rebuild walls with drainage that actually moves water away from the block face.
Tremron Parts & Our Repair-vs-Replace Approach
When we replace individual pavers, we match genuine Tremron units so color and texture blend with the existing field. Old Chicago brick pavers, Mega Arbel units, and Tremron Stone wall blocks are all available to us through local supply channels. For joint sand and edge restraints, we use quality aftermarket polymeric sand and commercial-grade edge restraints when OEM materials aren’t practical to source quickly in Foster City. The aftermarket polymeric sands we use meet or exceed the performance of OEM products, and they’re often more readily available for same-week repairs.
Our honest rule on repair versus replace: if more than roughly a third of a paver field is heaved, spalled, or drained wrong, spot patching just moves the failure around. A repaired base is what actually stops the failure. We’ll tell you which situation you’re in before any work starts. Call (877) 752-3868 for an assessment.
Our Tremron Service Process – Step by Step
- 1
Diagnosis. We start by checking the paver condition, base depth, slope, drainage, and edge restraint. On Foster City lagoon-side lots, we also check the water table influence and look for signs of fill-soil settlement.
- 2
Repair or install. For repairs, we remove affected units, correct the subgrade, re-compact, and re-set pavers with matching units and fresh polymeric sand. For new installations, we excavate to proper depth, lay geotextile separation fabric, compact the base in lifts, and set edge restraints before pavers go down.
- 3
Testing and drainage check. Before we finish, we run water across the field to verify slope and drainage. On high-water-table lots in Foster City, we confirm water moves off the paver surface and away from the foundation line, not into it.
- 4
Warranty and follow-up. We stand behind our base work and installation. If something shifts in the first year, we’re back to fix it. That’s the point of doing it right the first time.

FAQs – Tremron Construction Service in Foster City
The white bloom is efflorescence, caused by moisture moving through the paver and depositing mineral salts on the surface. In Foster City, high groundwater and lagoon-adjacent lots make this common. The fix is almost always in the base: proper drainage, a geotextile separation layer, and correct joint sand. Surface cleaning alone won’t stop it. Call (877) 752-3868 for a drainage assessment.
Yes. We source genuine Tremron units for replacement so color and texture blend with the surrounding field. For older installations where the color has shifted, we can often pull matching units from less-visible areas and use new units where they’ll blend best. But if more than a third of the field is compromised, we’ll recommend full replacement with a rebuilt base.
They are, when installed correctly. Tremron pressed-concrete pavers hold up well to Bay Area weather, but they need a properly compacted base, a geotextile separation layer, and positive slope for drainage. On Foster City’s engineered fill, skipping any of those steps leads to movement and efflorescence within a few years, unlike our Redwood Shores Tremron service where similar conditions demand the same care. We install for the water table, not against it.
Paver driveway installation in Foster City typically runs $7,000 to $18,000 depending on size, access, base depth, and the Tremron series you choose. Full driveway replacement with a new base runs $5,000 to $14,000. Call (877) 752-3868 for a free, written estimate on your specific driveway.
Yes. Tremron Stone and Stonewall blocks require a gravel drainage column behind the wall, filter fabric, and often a perforated drain pipe at the base. Without it, hydrostatic pressure builds and the wall leans. On Foster City’s flat, high-water-table lots, this is the most common retaining wall failure we see. We build drainage into every wall we set.
We are an independent Tremron service provider, not a factory-authorized installer. Using quality aftermarket polymeric sand and edge restraints does not void the Tremron paver warranty, but we recommend checking your specific product documentation. We install to manufacturer specifications and use genuine Tremron units for replacement, so your warranty position stays intact where it applies.

A Foster City homeowner on a lagoon-side lot had Tremron Old Chicago brick pavers on the driveway with heavy white efflorescence and joints washing out every winter. We pulled the field, found the base was only a few inches of uncompacted class II with no edge restraint at the apron. We re-excavated to proper depth, added a geotextile separation layer, re-set the pavers on a compacted base with new edge restraints, and finished with polymeric joint sand. Six months later the efflorescence had stopped blooming and the joints held through the rainy season.
