Tremron Home Additions & ADU: The Miami Owner's Guide
Home additions and ADU construction in Miami typically run $53,100 to $153,400 for a full Tremron-style build, and we can usually get a site assessment scheduled within a few days. Most Miami homeowners don't discover their Tremron paver or block system has a problem until they see cracking, settling, or drainage issues around an existing structure. We stock Tremron-compatible pavers, blocks, and hardscape materials on our trucks, and we're one of the few Miami contractors who'll give you a line-item price before we start.
Here's what we see happen: Miami's wet season, salt air, and sandy soil work on concrete and pavers year-round. A driveway apron or patio base that looks fine in January can be shifting by August. If you're planning an addition or ADU that ties into existing Tremron hardscape, the base and drainage matter as much as the pavers on top. The failure is almost never the Tremron product itself. It's the prep underneath, or the way an older installation handled water.
Which Tremron Models This Applies To
Tremron manufactures a full line of concrete pavers, retaining wall blocks, and hardscape products across several series. The most common ones we work with on Miami additions and ADU projects are the Tremron Estate Paver line, the Olde Towne paver series, and their structural retaining wall blocks. If you're unsure what you have, look at the side of a paver or block. Tremron stamps most products with a code near the edge. For pavers, the thickness tells you a lot: 60mm pavers are rated for pedestrian use and light residential patios. If you're putting a driveway or a vehicle-load surface next to an ADU, you need 80mm or thicker, and Miami code typically calls for that on any surface that carries a car or equipment.
One compatibility gotcha we run into: Tremron color blends fade differently in Miami sun than they do in other Florida markets. A paver batch from five years ago will not match a new batch exactly. If your ADU project needs a partial hardscape replacement rather than a full redo, expect color variation. We usually recommend a full overlay or a planned transition so the old and new zones are intentional, not accidental. On the block side, Tremron wall blocks are modular, but not all series interlock across lines. You can't mix a Sierra block with an Estate block and expect the wall to hold. We match the series, not just the size.
OEM versus aftermarket matters less here than it does with appliances or mechanical parts. Tremron is the OEM for their own concrete products. There isn't a meaningful aftermarket paver that matches their profile, so we spec genuine Tremron for hardscape and structural block. The only substitution we'll make is for base materials, drainage components, and reinforcement, where brands like NDS or Surebond perform as well or better in Miami soil conditions.

Signs Your Tremron Home Additions & ADU Is Failing
- Pavers settling or dipping near the foundation. This points to insufficient base compaction or a drainage problem pushing sand out from under the stones. In Miami, we most often see this on the south side of structures after heavy summer rain cycles.
- Water pooling against a Tremron wall or paver edge after rain. That's a slope or drainage failure, not a paver defect. Left alone, standing water will undermine the base and start moving blocks. We fix the pitch, then reset the pavers.
- Cracks running through multiple pavers in a straight line. Concrete pavers don't crack in straight lines by accident. That's usually a settling seam or a base layer that was never properly keyed into the surrounding grade.
- Retaining wall blocks leaning or separating at the seams. Miami's sandy soil loses shear strength when saturated. A wall that looks fine in dry season can shift visibly after one heavy storm if it lacks proper drainage gravel and a geogrid tie-back.
- White chalky residue on pavers or blocks. That's efflorescence, which is cosmetic but common in coastal Miami air. It doesn't mean the Tremron product failed, but it does tell you moisture is moving through the material. We treat it and then address the drainage source.

AfterReplacement Cost & What's Included
For a full home addition or ADU project in Miami, the range is $53,100 to $153,400 depending on square footage, foundation work, and how much existing Tremron hardscape has to be removed and rebuilt. That's an all-in number: permits, materials, labor, hardscape, and the finish work. Smaller scopes, like resetting a failed paver patio or rebuilding a retaining wall before an ADU goes in, typically run $4,130 to $12,980 for patios and $8,260 to $21,240 for paver driveways.
What drives the cost: access to the site, the condition of what's underneath, and whether Miami permitting triggers stormwater or flood-zone requirements. Miami-Dade has specific rules about impermeable surface coverage on residential lots. If your addition pushes you over the allowed percentage, you'll need a drainage plan, which adds cost. We don't hide that. We put it on the estimate the first time.
Every job includes a written price before work starts, and we back the hardscape portion with our 365-Day Done Right Promise. If pavers shift or a wall settles within a year, we come back. That's the Relay Standard we've run since 2005: live arrival time, photo updates, and a digital invoice you pay from a link.
DIY or Call Us?
You can check a few things safely. Walk the area after a hard Miami rain and note where water sits. Look for pavers that rock underfoot. Measure the gap between your wall blocks and the top course. Those observations help us quote faster. What you shouldn't do is start pulling pavers and digging out a base. Miami soil is sandy and collapses fast. A trench more than four feet deep near a foundation or wall needs shoring, and cutting Tremron pavers without a wet saw produces silica dust and jagged edges. This is concrete work, not a landscaping project. One wrong cut on a structural wall block and the whole course line is off.

FAQs
Tremron concrete pavers and structural blocks typically last 30 to 50 years in Miami when the base and drainage are done correctly. The product itself is not the weak point. The Florida limestone and sand under it is. Poor compaction or bad drainage can cut that lifespan to 10 years or less, which is why we spend more time on the base than on the stones.
Yes, if the pavers themselves are intact, we can lift the affected section, recompact the base, and reset the original Tremron pavers. If the base has washed out or the pavers are cracked through, a full reset in that zone is the honest fix. Call us at (850) 801-8046 and we'll tell you which one you're looking at after a site visit.
A typical addition or ADU in Miami runs 4 to 8 months from permit to final inspection, depending on scope and anything Miami-Dade permitting kicks back. The hardscape portion, like a driveway or patio tie-in, usually takes 3 to 7 days once we're on site. You'll get a timeline in writing before we start, with photo updates at every stage.
We keep the most common Tremron series on hand for quick turnarounds on repairs, but for full additions and ADU hardscape packages we order from Tremron's Florida yards with a 3 to 5 day lead time. That gets you the exact color blend and thickness your project calls for.
