Techo-Bloc Home Additions & ADU: The Fresno Owner’s Guide
A full home addition or ADU built on Techo-Bloc materials in Fresno typically runs $45,000–$130,000 installed, depending on square footage, foundation work, and whether you’re adding living space or a detached unit. We stock and install Techo-Bloc-compatible hardscape and structural components, and we match your existing product line so the new work doesn’t look like an afterthought. Most Fresno owners discover they need this page when a patio base, retaining wall, or paver system tied to their addition starts shifting, cracking, or draining wrong after the first heavy rain season.
You’re not here for a brochure. You’re here because a Techo-Bloc part of your project failed or is about to fail, and you want it priced, matched, and fixed without a runaround. That’s what we do.
Which Techo-Bloc Models This Applies To
Techo-Bloc runs several product families that show up in Fresno additions and ADUs: Blu 60 and Blu 80 pavers for driveways and patios, Para and Mista wall systems for tiered lots and raised foundations, and Villagio or Semma slabs for walkways and pool surrounds. Each series has different joint widths, thicknesses, and base requirements. The gotcha most owners hit: you cannot swap a Blu 60 paver for a Blu 80 without redoing the base. The 80mm paver is rated for vehicle loads, the 60mm is not. If your addition includes a driveway apron or parking pad, that’s the first spec to confirm.
Identifying your part is straightforward. Flip a loose paver or wall block and look for the Techo-Bloc stamp with the series code. On caps and steps, the code is on the back face. If it’s worn off, measure the thickness in millimeters. That number plus the surface texture (smooth, shot-blasted, or embossed) tells us exactly what to order. We default to OEM Techo-Bloc stock for color-matching, but for some discontinued colorways we source aftermarket equivalents that match within one shade. We’ll show you both options side by side before you sign anything.
Bradford Remodeling Co Fresno is an independent contractor. We are not affiliated with Techo-Bloc, but we install their products regularly and keep their spec sheets in the truck.

Signs Your Techo-Bloc Home Additions & ADU Is Failing
- Pavers rocking or clicking underfoot. This means the bedding sand has eroded or washed out. In Fresno’s clay-heavy soil, poor drainage under the base is usually the culprit. The paver itself may be fine; the base is what failed.
- Wall blocks leaning or bulging outward. Retaining walls on additions with sloped lots take real lateral pressure. A bulge means the geogrid or drainage gravel behind the wall wasn’t installed to spec, and the wall is doing work it was never designed to do.
- Water pooling against the foundation or slab edge. Techo-Bloc permeable systems reduce runoff, but a standard paver base with clogged joints will channel water toward the structure. In Fresno, that means slab heave risk during wet winters and dry-summer cracking.
- Gaps widening at joint lines. Polymeric sand joints should be tight. Wide, crumbling joints mean the paver field is shifting, usually because the edge restraint failed or the sub-base wasn’t compacted in lifts.
- Steps or caps separating from the wall body. Caps are bonded, not structural, but when they loosen and start walking, the wall below is moving. That’s not a cosmetic fix; it’s a sign the wall’s internal structure is compromised.

AfterReplacement Cost & What’s Included
For an addition or ADU hardscape scope tied to Techo-Bloc, plan on $45,000–$130,000 depending on whether we’re rebuilding a patio base, replacing a retaining wall, or doing full paver work around a new structure. A standalone wall rebuild with Techo-Bloc blocks in Fresno typically lands in the $15,000–$40,000 range once you factor in demolition, drainage, and compaction. A paver driveway or large patio resurface runs $18,000–$45,000 installed.
Every quote includes the line items: excavation and haul-off, base material, compaction, Techo-Bloc product, edge restraint, polymeric sand, and labor. No allowances for “unexpected conditions” that balloon the price at the door. If the underlying soil needs deeper excavation, that gets called out in the written estimate before we start, not added to an invoice later. The estimate says what we build, and we build what the estimate says.
All work carries the 365-Day Done Right Promise. If the pavers shift, the wall moves, or the drainage fails within a year of completion, we come back and correct it at no charge. No phone tag, no “that’s not covered.” It’s in writing on the estimate and on the guarantee sheet you get at close-out.
DIY or Call Us?
You can safely check the obvious: walk the paver field, look for standing water, check that downspouts divert away from the base. Those observations help us diagnose faster. What you shouldn’t do is start pulling pavers or dismantling a wall block. Retaining walls under load can collapse if the facing is removed without shoring, and a dropped section of Techo-Bloc wall weighs enough to do real damage to hands and feet.
If the issue is a loose cap or a single sunken paver, a handyman with a tamper and fresh sand can often reset it. If the wall is leaning, the base is washing out, or water is moving toward your foundation, call a crew that does this for a living. That’s us. We show up with the right Techo-Bloc match, the right base material, and a written price before the first paver comes up. Call (559) 785-2712 for a free estimate.
FAQs
A properly built Techo-Bloc paver system lasts 25 to 30 years in Central California; walls can go 40 years or more. The failure point in Fresno is almost never the block itself. It’s the base, the drainage, or the edge restraint. If those are done to spec, the top layer stays put. Call (559) 785-2712 and we’ll tell you what you’re actually looking at.
Yes, in most cases. If the paver field is sound and only one section of wall or base has failed, we can match the product and rebuild just that section. The challenge is color matching older Techo-Bloc that has weathered; we’ll pull from the least visible area and use the new stock in the field to keep the transition clean.
A paver patio or small wall section typically takes 3 to 5 working days including base prep and compaction. A full addition or ADU hardscape package can run 2 to 4 weeks depending on weather and the scope of excavation. We give you a schedule in the written estimate, and we hold to it.
We keep common Techo-Bloc series, including Blu 60, Blu 80, and Mista wall blocks, at our Fresno yard for quick starts. Discontinued or specialty colorways get ordered direct, typically a 5 to 10 business day lead. If your product line is older, we’ll identify it, check availability, and give you the lead time in writing before any money changes hands. Call (559) 785-2712 for an exact quote, estimates are free.
