Techo-Bloc Home Additions & ADU: The Fort Lauderdale Owner’s Guide
Techo-Bloc home additions and ADU projects in Fort Lauderdale typically run $45,000 to $130,000 installed, depending on square footage, foundation work, and whether you’re building an attached addition or a detached accessory dwelling unit. We stock and install Techo-Bloc hardscape materials as part of these larger builds, and we can usually get your project scoped and priced within a week of the first site visit. Most owners call us because they’ve got a failing retaining wall, a cracked paver base, or a drainage issue tied to their existing Techo-Bloc hardscape that’s now threatening the structural integrity of a planned or existing addition.
Which Techo-Bloc Models This Applies To
If you’re planning a home addition or ADU in Fort Lauderdale, the Techo-Bloc products that matter most are their structural wall systems and paver lines. The Blu 60 mm and Blu 80 mm retaining wall units are the workhorses for raised foundations and grade changes, while the Villagio, Borealis, and Industria paver lines carry the load for driveways, walkways, and patio areas adjacent to new living space. The compatibility gotcha we run into constantly: Techo-Bloc’s 60 mm pavers are not interchangeable with their 80 mm pavers in the same pattern without a transition course, and mixing them on a single plane creates lippage that will trip someone within a year. Check the back of any existing paver for the stamped product code, or measure the thickness with a tape. If you’re matching old Techo-Bloc to new for an addition that extends an existing patio, the dye lots will not match perfectly after five-plus years of South Florida sun, so plan on a border course or full-field replacement for visual continuity.
OEM versus aftermarket matters less for Techo-Bloc than it does for appliances. Techo-Bloc’s raw materials are concrete, aggregate, and color pigments, and the aftermarket equivalent is simply another manufacturer’s paver or wall block with the same dimensions. The honest tradeoff: Techo-Bloc’s color consistency and freeze-thaw performance are better than most budget alternatives, but you’ll pay $2 to $5 more per square foot for the name. We stock Techo-Bloc architectural products on hand for inspection, and we also carry compatible systems from Belgard and Unilock, plus KraftMaid, Cambria, and Silestone for interior finishes, so you’re not locked into one product line.
Styles & brands we work with
Signs Your Techo-Bloc Home Additions & ADU Is Failing
- Wall units are leaning or bulging outward. This means the geogrid reinforcement behind the wall was either skipped, under-spec’d, or drainage behind the wall has failed and hydrostatic pressure is pushing the wall out. In Fort Lauderdale’s wet season, this is the number one failure we see on walls built more than five years ago.
- Pavers are sinking or pooling water in low spots. The base was not compacted in lifts, or the original excavator cut corners on depth. A proper Fort Lauderdale paver base goes down 6 to 8 inches deep, and anything less will shift within two years in our sandy, shifting soil.
- Cracks running through multiple pavers in a straight line. This is a settling fracture, not a paver defect. The subgrade is moving, which means water is getting underneath and eroding the base, or tree roots are pushing up from below.
- Joint sand is washing out after every rain. Polymeric sand should harden after installation and stay put. If it’s washing out, the sand was applied wet, the pavers weren’t fully dry, or the joints were never properly vibrated to settle the sand to the bottom of the joint.
- Efflorescence (white chalky film) covering large sections of the surface. Some efflorescence is normal in the first year as concrete cures, but heavy recurring blooms in Fort Lauderdale’s humidity usually mean water is trapped behind or under the pavers and wicking minerals to the surface continuously.

AfterReplacement Cost & What’s Included
For a Techo-Bloc home addition or ADU project in Fort Lauderdale, here’s the price breakdown we give every homeowner before starting work:
- Home addition (attached, 400 to 800 square feet): $45,000 to $130,000 installed
- ADU construction (detached, separate structure): $90,000 to $220,000 installed
- Garage conversion to living space: $30,000 to $80,000 installed
- Techo-Bloc paver patio or walkway as part of the project: $3,500 to $11,000 depending on square footage
- Techo-Bloc retaining wall repair or rebuild: $2,000 to $9,000 depending on height and length
What determines where you land in those ranges: whether we’re pouring a new foundation or tying into the existing slab, the FEMA elevation requirements for your specific Fort Lauderdale flood zone, whether the addition needs its own HVAC zone and electrical subpanel, and how much existing hardscape has to be removed and reset. Every line item is written down before we start. No change orders without your signature. The 365-Day Done Right Promise applies to the full project: if anything we built or installed fails within a year of completion, we return and make it right at no cost.
DIY or Call Us?
You can safely inspect your existing Techo-Bloc hardscape to diagnose what’s failing. Look for the warning signs above, check for exposed geogrid behind any leaning wall section, and watch where water flows during a heavy Florida downpour. What you should not do is attempt to rebuild a retaining wall over three feet tall, cut pavers without proper respiratory protection, or excavate near an existing foundation without a surveyor marking utilities. Silica dust from cutting concrete pavers is a genuine lung hazard, and a wall that collapses during a DIY rebuild can crush whatever is downhill from it. If you’ve got a failing wall or paver field that’s connected to an addition or ADU you’re planning, call us at (754) 354-3720. We’ll tell you what we found, what it takes to fix it, and what it will cost, before we touch a thing.
FAQs
Techo-Bloc pavers and wall units installed correctly in Fort Lauderdale should last 25 to 40 years before needing any structural repair, though surface color will fade gradually from UV exposure and salt air. The base and drainage system matter more than the product itself here. Call (754) 354-3720 if you want us to inspect your existing hardscape and tell you honestly how many years are left in it.
Yes, if the lean is less than a few degrees and the blocks themselves are not cracked, we can disassemble the wall, re-grade and compact the base, install proper drainage, and reset the same blocks, which typically saves 40 to 60 percent versus a full replacement. If the wall has shifted more than that, the blocks and geogrid are usually compromised and a rebuild is the honest answer. Call (754) 354-3720 for an inspection and we’ll tell you which path applies to your wall.
A typical home addition or ADU in Fort Lauderdale takes 4 to 8 months from permit application to final inspection, depending on the scope, the city’s plan review queue, and whether we hit hurricane season during the build. Paver driveway or patio work within that project usually compresses into a 1 to 2 week window once the structure is up. Call (754) 354-3720 and we’ll give you a realistic timeline for your specific project after the first site visit.
We maintain working relationships with Techo-Bloc’s South Florida distributors and can have most product lines in Fort Lauderdale within 5 to 10 business days of your signed contract, with select samples available for inspection at our shop. We do not warehouse every Techo-Bloc SKU on-site because the product line is extensive and storage space is better spent on materials that turn over quickly. Call (754) 354-3720 to check availability on the specific product line you’re matching.
Call (754) 354-3720 to schedule your free estimate. We’ll walk your property, answer your questions about Techo-Bloc products and your addition or ADU plans, and hand you a written price before any work begins.
