Tremron Home Additions & ADU Nationwide

Tremron Home Additions & ADU: The West Palm Beach Owner’s Guide

Tremron pavers, retaining wall blocks, and hardscape components used in West Palm Beach home additions and ADU projects typically run $45,000-$130,000 installed, depending on whether you’re extending a foundation pad, building a detached unit, or integrating outdoor living space. We stock Tremron-compatible Belgard and Techo-Bloc alternatives on our trucks, and most ADU foundation and hardscape assessments happen within 48 hours of your call. Most homeowners discover their Tremron installation needs attention when settling cracks appear after Florida’s wet season, or when a paver patio installed during a previous addition starts draining toward the structure instead of away from it.

Which Tremron Models This Applies To

Tremron’s product lines show up in West Palm Beach additions in three main forms: the Olde Towne paver series for patios and walkways, Stonegate retaining wall systems for grade changes on sloped lots, and Aqua permeable pavers where stormwater management is required by Palm Beach County code. The critical compatibility gotcha is the Olde Towne III versus earlier Olde Towne iterations: the III series uses a 60mm thickness and chamfered edge profile that does not interlock cleanly with the 80mm commercial-grade pavers some contractors mixed in during the 2015-2019 building boom. Check the paver edge: a sharp 90-degree corner means pre-III or commercial spec; a slight bevel indicates III-series compatibility.

For retaining walls, Tremron’s Stonegate comes in 6-inch and 8-inch face heights with different pin connection systems. We’ve found walls built with the 6-inch unit but capped with 8-inch-compatible coping stones, which shears the pin slots within two Florida wet-dry cycles. The label stamp is usually on the back face of the block, visible only if you pull one from the top course. We document this during assessment with photos you’ll receive in your project record.

Rowan Construction Group West Palm Beach is an independent contractor with no affiliation to Tremron. We source through regional distributors and can match existing Tremron color profiles from Belgard’s Dublin series or Techo-Bloc’s Eva when Tremron’s current production run has shifted from your original dye lot, which happens roughly every 18 months in the Florida market.

Signs Your Tremron Home Additions & ADU Is Failing

• Pavers settling in a wave pattern. This usually means the base course was compacted in lifts too thick for the soil type, or the original contractor skipped geotextile separation on West Palm Beach’s sandy subgrade. The Tremron unit itself is likely intact; the failure is below it.
• White efflorescence blooming across the surface. Calcium hydroxide migration is common in Tremron’s lighter color blends, especially Sand Dune and Sierra. It does not weaken the paver, but in an ADU project where indoor-outdoor continuity matters, it’s a cosmetic failure that signals moisture is moving through the bedding sand incorrectly.
• Retaining wall leaning or stair-step cracking. Stonegate walls without proper drainage aggregate behind them hydrostatically load during our summer thunderstorms. The wall tilts toward the structure, which in an ADU setback can encroach on code-required clearances.
• Permeable pavers clogging and ponding. Tremron Aqua pavers require joint aggregate maintenance every 24-36 months in South Florida’s pollen and leaf-drop environment. When clogged, they lose their NFPA stormwater credit, which can trigger a code violation if your ADU permit relied on that calculation.
• Chipped corners on driveway-adjacent additions. Olde Towne’s chamfered edge is structurally thinner than the body; repeated vehicle overhang from an expanded garage or porte-cochere addition spalls the edge. The paver is serviceable but the pattern looks ragged.

Replacement Cost & What’s Included

Home additions and ADU hardscape work in West Palm Beach falls in the $45,000-$130,000 range, with Tremron-specific paver replacement or wall reconstruction typically landing in the $8,500-$28,000 band for the hardscape portion alone. What drives the spread: whether we’re matching existing dye lots (requires larger buffer stock), whether the base course can be salvaged, and whether Palm Beach County requires updated stormwater calculations for the revised footprint.

Under Clause 1 of the Haven Standard, your written price arrives before any work starts. No change proceeds without a signed change order. Our 365-Day Done Right Promise covers the installation; material defects fall to manufacturer warranty, which we file on your behalf with documentation from our photo record.

DIY or Call Us?

What you can safely check yourself: lift one paver from an inconspicuous corner and photograph the base layer. If you see standing water, mud, or organic material where clean crushed stone should be, you’ve found the problem. You can also verify your Tremron series using the edge profile check described above.

Where DIY goes wrong: retaining wall drainage repair involves working below grade with potential utility conflicts; paver base reconditioning requires plate compaction in controlled lifts that most rental equipment cannot achieve; and any modification to an ADU’s hardscape footprint may trigger Palm Beach County’s requirement for updated as-built stormwater documentation. We’ve seen homeowners in the Northwood and El Cid neighborhoods start a weekend paver reset and end up with a code enforcement notice because the revised impervious surface calculation wasn’t filed.

Call (561) 475-3903 and we’ll assess what’s actually failing, photograph what we find, and deliver a written price before any work starts. Estimates are free.
