Techo-Bloc Home Additions & ADU: The West Palm Beach Owner’s Guide
If you’re planning a home addition or ADU in West Palm Beach with Techo-Bloc pavers, walls, or steps, the installed project typically runs $45,000 – $130,000 depending on square footage, site prep, and design complexity. We handle the full scope: foundation work, framing, roofing, HVAC tie-in, and the hardscape details that make Techo-Bloc products look right against a new structure. Most owners reach out after realizing their existing concrete pad or paver base wasn’t built to carry the weight of a new room, or they’ve found their current Techo-Bloc retaining wall shifting because the original install skipped the geogrid reinforcement that South Florida’s sandy soil requires.
Which Techo-Bloc Models This Applies To
Techo-Bloc’s compatibility with home additions and ADUs comes down to three product families we install most often in West Palm Beach. The Blu 60 slab (60mm thick) is the workhorse for patios and walkways tied to new living space; the Raffinato series carries a smooth face that reads more formal and works well for covered outdoor rooms attached to an addition; the Semma retaining wall block is what we spec when grade change is involved, which happens often on West Palm Beach lots with even a few feet of slope. The gotcha: Techo-Bloc’s 60mm slabs are not interchangeable with standard 2-inch concrete pavers. The base depth, the sand type, and the edge restraint all change, and a crew that treats them like generic pavers will have a wobbling surface within two rainy seasons. We stock full pallets of Blu 60, Raffinato, and Semma in our West Palm Beach yard, which means no six-week lead time from the manufacturer when your addition is ready for hardscape.
We’re an independent West Palm Beach contractor, not a Techo-Bloc distributor. That matters because we spec the product that fits the job rather than pushing whatever is left in inventory. We also work with KraftMaid, Cambria, and Silestone on the interior side, so the same crew handling your addition’s exterior can coordinate the kitchen and bath finishes without a second handoff.

Signs Your Techo-Bloc Home Additions & ADU Is Failing
Most of the failure calls we take for additions and ADUs in West Palm Beach are less about the pavers themselves and more about what’s underneath them. Here’s what we usually find:
- Settling pavers against the new foundation wall. The backfill wasn’t compacted in lifts, and after the first heavy rain the soil dropped two inches. The fix is removing the affected area, recompacting with a plate compactor, and reinstalling on compacted base, not just dumping sand on top.
- Water pooling at the new structure’s drip line. No one accounted for roof runoff from the addition, and now the pavers are sitting in standing water after every afternoon thunderstorm. This needs a drainage correction, usually a channel drain or a regrade away from the foundation before the pavers go back.
- Retaining wall leaning into the new walkway. South Florida’s sandy soil doesn’t hold a vertical cut on its own. A Techo-Bloc Semma wall without geogrid reinforcement will lean, and once it’s past about an inch out of plumb, it’s a rebuild, not a repair.
- Pavers shifting or spreading at the outside edges. The original install skipped edge restraint, or used a cheap plastic strip that’s already failed. On a West Palm Beach addition where the pavers meet a lawn or garden bed, this shows up within the first year.
- Visible gaps opening between pavers and the foundation. This isn’t just cosmetic. A gap means water is getting down to the base layer, and in West Palm Beach’s wet season that’s a slow washout of the material holding everything level.

AfterReplacement Cost & What’s Included
For a home addition with Techo-Bloc hardscape in West Palm Beach, the $45,000 – $130,000 range covers two very different scopes. The lower end is a modest bump-out or enclosed patio with basic interior finish, while the higher end includes full ADUs with kitchens, baths, and substantial paver work. Here’s the breakdown:
- Home addition: $45,000 – $130,000 depending on size, roof complexity, and interior finish level
- ADU construction: $90,000 – $220,000 for a permitted accessory dwelling unit with kitchen and bath
- Garage conversion: $30,000 – $80,000 when converting an existing garage to living space
- Techo-Bloc paver patio or walkway tied to the structure: $3,500 – $11,000 depending on square footage and base prep
What drives the price on the paver side is what’s underneath: if the existing base is compromised (and in West Palm Beach it often is after a few years of wet-dry cycle), the excavation and recompaction can double the hardscape cost. We always include the full base rebuild in our written price, not as a change order that shows up after we start digging. That’s part of the written scope Graham walks through, item by item, before the first tool leaves the truck. The 365-Day Done Right Promise applies to the entire project, including the hardscape: if something isn’t right after we’ve finished, we make it right.
DIY or Call Us?
There’s an honest split here. You can safely assess things like visible settling, pooling water, or gaps opening at the edges. What you shouldn’t do is start lifting and resetting 60mm Techo-Bloc slabs yourself. These pavers are heavy, the base layers matter more than the surface, and in Florida heat a full day of hand-compacting base material is how people end up in the ER with heat exhaustion. The structural connection between your addition’s foundation and the surrounding hardscape is also not a DIY fix; if water is getting to your footing, that’s a foundation issue, not a paver issue. Call (728) 203-3270 and Graham will walk the site with you. He’ll tell you if it’s a simple reset or a full rebuild, and you’ll get a written price either way.
FAQs
With a properly compacted base and edge restraint, Techo-Bloc pavers in West Palm Beach typically last 30 to 40 years before the surface starts showing real wear. The base layer is what fails first in our climate, not the paver itself. Call (728) 203-3270 if you’re seeing settling or shifting; we’ll assess the base before recommending any surface work.
Yes, if the pavers themselves are intact and the problem is isolated settling, we can lift the affected section, recompact the base, and reset the same pavers. If the edge restraint has failed across the entire perimeter, or the wall is leaning, a partial repair usually costs more than doing it right once. We’ll show you the numbers either way.
A typical home addition runs 3 to 5 months from permit to final walkthrough; an ADU runs 5 to 8 months depending on design complexity and permit review time with the city of West Palm Beach. The hardscape portion, if it’s pavers and walkways, usually takes 3 to 7 days once the structure is up. Your written scope includes a start and end window, and Graham calls when he says he will.
We stock Blu 60, Raffinato, and Semma in our West Palm Beach yard, so there’s no manufacturer lead time on the pavers and wall blocks we spec most often. For unusual colors or special-order series, we’ll quote the lead time in writing before you commit. Call (728) 203-3270 and we’ll check availability for your specific product while you’re on the phone.
