Techo-Bloc Home Additions & ADU Nationwide

Techo-Bloc Home Additions & ADU: The Pompano Beach Owner’s Guide

We stock and install Techo-Bloc-compatible hardscape systems for home additions and ADU projects in Pompano Beach, with typical installed pricing from $45,000 to $130,000 for additions and $90,000 to $220,000 for standalone ADUs. Most Techo-Bloc paver patio, walkway, and retaining wall integrations for addition footings and ADU foundations can be scoped and priced same-week. Homeowners usually discover a problem when settling pavers crack after rain, retaining walls tilt where the addition meets the original structure, or drainage channels clog with Pompano Beach’s sandy soil and seasonal downpours.

Which Techo-Bloc Models This Applies To

Techo-Bloc produces several product lines that integrate with home addition and ADU construction in South Florida. The most common we encounter on Pompano Beach jobs are the Antika permeable pavers used for ADU parking pads, Blu 80 slabs for addition patio extensions, and Mini-Creta retaining walls where grade changes between existing and new construction require stabilization.

To identify your exact product, check the underside of a loose paver for the Techo-Bloc stamp and production date code, or measure the unit: Antika runs 100 mm thick, Blu 80 is 80 mm (hence the name), and Mini-Creta units are 150 mm high with a split-face finish. The color batch matters for matching - Techo-Bloc’s Beige Cream and Greyed Nickel are the two tones we see most often in Pompano Beach’s coastal-light palettes, but 2021-2023 production runs of Beige Cream had a slightly warmer cast that reads as mismatched if you source from 2024 inventory.

We are an independent contractor, not affiliated with Techo-Bloc. For warranty-matched repairs on newer installations, OEM-sourced units from authorized distributors are the only path. For older hardscape where the original batch is discontinued, we source color-matched equivalents from our vetted supplier network and document the variance in writing before any work starts.

Signs Your Techo-Bloc Home Additions & ADU Is Failing

• Pavers settle or rock underfoot near the addition foundation. This usually means the compacted stone base (called the sub-base, typically 6-8 inches of crushed limestone in our specs) has washed out where the new construction tied into the old. Pompano Beach’s sandy native soil doesn’t hold grade without proper geotextile fabric, and we’ve found crews who skipped that layer on rushed addition jobs.
• Retaining wall leans or shows stair-step cracks. The wall is carrying more load than designed, often because the addition’s roof runoff was directed behind it without a proper drainage aggregate. Mini-Creta walls need 12 inches of clean ¾-inch stone behind the face and a perforated drain pipe at the footing - when that’s missing, hydrostatic pressure builds fast in our summer storms.
• White powder blooms on paver surfaces. This is efflorescence, mineral salts migrating through the concrete. It’s cosmetic, not structural, but in Pompano Beach’s humidity it can persist for months and signals that water is moving through the joint sand rather than draining through the bedding layer as designed.
• Joint sand washes out after every heavy rain. Polymeric sand failure - either the wrong product was used (standard sand instead of polymer-modified), or it was installed on damp substrate and never cured properly. Open joints let water into the bedding layer, which starts the settlement cycle.
• ADU parking pad holds standing water more than 24 hours after rain. Permeable pavers like Antika are supposed to drain through the joints into the stone reservoir below. Clogging from fine sand migration, or a reservoir layer that was never installed to Techo-Bloc’s 18-inch minimum spec, turns the system into a standard impervious surface with all the drainage problems.

Replacement Cost & What’s Included

What drives the range: access (can we get a mini-excavator to the ADU site, or is everything hand-carried through a 3-foot gate?), the condition of what’s beneath the pavers (we’ve pulled up Blu 80 slabs in Pompano Beach and found cardboard used as a weed barrier - that all comes out), and whether the original installation included the proper base depths and drainage layers that Techo-Bloc’s engineering requires.

Every quote is a flat written price with line-item scope. Under Clause 1 of The Haven Standard, that price is delivered before any work starts. The 365-Day Done Right Promise covers the installation, and you’ll receive a documented photo record of the excavation, base prep, and finished work as standard - not as an upgrade you have to ask for.

DIY or Call Us?

There’s a short list of what a homeowner can safely check without risk: lift one paver at the edge and photograph what’s underneath, run a level across a 6-foot span to quantify settlement, or clear surface debris from drainage channels. What you find is useful information to share when you call.

What goes wrong fast: excavating without locating utilities (Pompano Beach requires a Sunshine 811 locate, and it’s free), cutting into a retaining wall without understanding the load it carries, or re-laying pavers without recompacting the base in 6-inch lifts - the surface looks fine for two months, then mirrors the original failure. The real discipline is in what you can’t see once the pavers go back down.

We carry Techo-Bloc-compatible base materials, geotextile, and drainage components on our trucks. For paver color matches, we pull from our Pompano Beach warehouse or source from the distributor network within 48 hours.
