Tremron Home Additions & ADU Nationwide

Tremron Home Additions & ADU: The Irvine Owner’s Guide

We stock and install Tremron-compatible hardscape and masonry components for home additions and ADU projects in Irvine, with typical installed pricing for Tremron-integrated work running $45,000-$130,000 for full additions and $90,000-$220,000 for detached ADUs. Most homeowners discover their Tremron installation needs attention when pavers settle unevenly after winter rains, joint sand washes out from between stones, or the permeable base beneath a Tremron Olde Towne or Aqua Paver surface fails to drain properly through Irvine’s clay-heavy soil. Measure twice, build it once, write it down.

Which Tremron Models This Applies To

Tremron manufactures several paver and retaining wall lines commonly specified for Irvine home additions and ADU hardscaping: the Olde Towne cobble-style paver, the Aqua Paver permeable series, the Mega-Lafitt and Bella Cobble textures, and the Sierra and Keystone retaining wall systems. To identify your specific product, check the edge spacer bars on installed pavers - Tremron stamps a mold identifier on the underside, visible if you lift a single unit from an inconspicuous corner. The color batch code, a four-digit number pressed near the spacer, tells us whether your installation came from Tremron’s Florida plant or their newer Georgia line; the Georgia-run products use a slightly different aggregate blend that affects how aftermarket sealers bond.

We source OEM Tremron replacement units where color match is critical, particularly for the Sierra Blend and Oak Run colorways that fade differently under UV exposure. For structural base repairs beneath the pavers, we use equivalent ASTM C936-compliant concrete pavers from Belgard or Techo-Bloc - brands we also stock - because the performance spec matters more than the stamp for subsurface work. The gotcha most Irvine homeowners miss: Tremron’s permeable Aqua Paver requires a specific 3/8-inch clean stone base depth that differs from standard ICPI guidelines; installing a conventional base voids the permeability warranty and pools water against ADU foundations during our January through March rainy stretch.

Signs Your Tremron Home Additions & ADU Is Failing

• Pavers rock or wobble underfoot. The bedding sand layer has eroded or the edge restraint has pulled away from the perimeter, often because Irvine’s expansive clay soil swelled during the last wet season and contracted, leaving voids beneath the screeded base.
• White haze or efflorescence blooms across the surface. Calcium hydroxide from the concrete matrix is migrating to the surface through capillary action; it is cosmetic but signals moisture is moving through the paver rather than draining through the joints as designed.
• Joint sand disappears within a single rainy season. The polymeric sand failed to activate properly during initial installation, or the joint width exceeds Tremron’s 1/16- to 3/16-inch spec for their standard lines, allowing washout into Irvine’s municipal drainage system.
• Sunken or heaved sections near the ADU foundation. Downspout discharge is undermining the compacted aggregate base, a common issue in Irvine’s Woodbridge and Northwood neighborhoods where zero-lot-line setbacks concentrate roof runoff against hardscape edges.
• Retaining wall blocks tilt or step out of plane. The geogrid reinforcement layer was omitted or improperly lapped during original construction, or drainage aggregate behind the wall has clogged with Irvine’s fine silty runoff, hydrostatically pushing the face forward.

Replacement Cost & What’s Included

What drives the range: access for excavation equipment, whether we need to protect existing landscaping in Irvine’s mature neighborhoods like Turtle Rock, and the depth of base failure. Our quotes include paver removal and salvage, base re-compaction to 98% Proctor density, bedding sand rescreeding, paver relay with new joint sand, and a documented photo record of the substrate condition before we cover it. Under Clause 1 of the Haven Standard, the price is written before anyone starts - no change proceeds without a signed change order. Every Tremron repair carries our 365-Day Done Right Promise.

DIY or Call Us?

An owner can safely check whether downspouts are discharging directly onto hardscape, whether joint sand is visibly missing, and whether edge restraints have pulled loose from stakes - these are observation tasks, not repairs. Where DIY goes wrong: lifting pavers without understanding the base layer beneath, attempting to recompact with a hand tamper rather than a plate compactor rated for the job, or guessing at joint sand depth and material. Tremron’s permeable systems in particular require precise base gradation that affects drainage toward Irvine’s storm requirements; get it wrong and you are redirecting water toward your ADU’s slab or your neighbor’s property line.
