Techo-Bloc Home Additions & ADU: The Sacramento Owner’s Guide
If you’re planning a home addition or ADU in Sacramento using Techo-Bloc hardscape materials, the full project typically runs $45,000 – $130,000 when you include slab work, framing, masonry, and finishes. We’re an independent remodeling contractor in Sacramento, not a Techo-Bloc dealer or affiliate, and we install Techo-Bloc products regularly because they hold up to our valley heat and winter rain better than most poured concrete alternatives. Most homeowners start this conversation because a previous addition attempt stalled, a patio slab failed, or they want the ADU done right the first time with real numbers on paper before demo day.
Which Techo-Bloc Products This Applies To
Techo-Bloc makes modular concrete pavers, retaining wall blocks, and slab systems that often anchor a Sacramento addition or ADU site package. The product lines we work with most are the Blu 60 and Blu 80 pavers for patio and walkway surfaces, the Estate and Mista wall block for raised foundations and planter retention, and the Borealis slab line for larger hardscape runs. The key gotcha homeowners miss: Techo-Bloc pavers are calibrated by manufacturing lot, so mixing a new pallet with a two-year-old pallet often leaves a visible height difference of 1/16 to 1/8 inch across the seam. We check lot codes before ordering so the finished surface reads as one plane, not a patchwork. For structural walls on an ADU pad, you want the Estate block at its full depth spec, not the thinner cap block, which is only rated for non-structural tops.

Signs Your Techo-Bloc Home Additions & ADU Project Is Failing
- Paver settling or lippage along the old slab edge: Sacramento’s clay soil expands when wet and shrinks when dry. If the original base was compacted to less than 4 inches of road base or installed over uncompacted fill, the pavers will shift within 12 to 18 months. The edge against the foundation is where it shows first.
- Efflorescence blooming across faces and joints: White mineral streaks on new Techo-Bloc mean water is moving through the substrate and pulling salts to the surface. It’s cosmetic at first, but it signals the drainage layer under the pavers isn’t shedding water the way it should be here in the Central Valley.
- Retaining wall leaning or separating at the midpoint: If a Techo-Bloc Estate wall shows a gap at the bond line, the geogrid reinforcement was likely skipped or the backfill wasn’t compacted in lifts. Sacramento’s freeze-thaw is mild, but saturated clay pushing against an unreinforced wall will lean it every time.
- Joint sand washing out after each rain: If you’re sweeping polymeric sand back into paver joints more than twice a season, the edge restraint has failed or the sand was never properly activated. This is one of the most common failure points we repair on additions built in the last five years across Sacramento.
- Cracking in a concrete patio slab adjacent to the ADU foundation: If the original patio slab heaves or cracks within a year of an addition going in, the slab was poured on soil that wasn’t re-compacted after the foundation trench work. The concrete is telling you the ground under it moved.

AfterReplacement Cost & What’s Included
In Sacramento, a home addition with Techo-Bloc hardscape work typically falls between $45,000 and $130,000 depending on square footage, wall blocks needed, whether the site requires soil correction, and how much of the existing hardscape has to come out first. An ADU project is its own animal and runs $90,000 – $220,000 all-in for a code-compliant build with a real foundation. Smaller rebuilt patios or paver replacements tied to an addition often land in the $3,500 – $11,000 range. What moves the number: soil condition, access for a machine or hand-carry work, drainage corrections, and whether you’re keeping any existing pavers to match. Every line item gets written down before we start, and the number on day one is the number on the invoice. If a paver run or wall we install fails within 365 days, we return and fix it at no charge, in writing.
DIY or Call Us?
You can check compaction on a failing paver area yourself: lift one paver near the edge and look at the base under it. If the base is less than 4 inches of crushed stone or it crumbles when you squeeze it, the original install was under-built. That’s good information to have when you call. What you shouldn’t do is rent a plate compactor and attempt a restart on a retaining wall or structural paver base without checking the geogrid spec and the lot code on any new Techo-Bloc pallet. If the wall already leans, block and soil have to come out before anything goes back, and doing that by hand on a Sacramento weekend is how people throw out a back or end up with a wall that leans somewhere new. Call us at (279) 300-1177 and we’ll come look at it, write you a number, and tell you exactly what it takes to fix it right.
FAQs
With a correct base and proper drainage, Techo-Bloc pavers and Estate block should last 25 to 40 years in the Sacramento climate before you see meaningful surface wear or joint failure. The paver itself rarely fails first; the base under it does. Most failures we see trace back to compaction that was skimped on the original build, not the block quality.
If you’re looking at a failing area on your addition hardscape, call (279) 300-1177 and we can tell you in one visit whether the paver is the problem or the prep underneath it.
Yes, in many cases. Spot-leveling a settled paver area and re-sanding joints often buys several more years, especially if the only issue is localized washout. A leaning retaining wall is a different story: once the block has moved, the proper fix is disassembly, re-grading the base and backfill, and rebuilding with the geogrid spec correct this time. Patched-look fixes on walls don’t hold in Sacramento’s clay.
Call (279) 300-1177 for a free estimate on either repair or full replacement, and we’ll give you the written price for both.
A patio or paver replacement tied to an existing slab typically takes 3 to 7 working days from tear-out to finished surface. A full home addition using Techo-Bloc hardscape as part of the site package runs 8 to 16 weeks depending on permitting, foundation, and any structural work. ADUs are their own permit cycle in Sacramento and usually run 5 to 9 months from plans to final inspection.
We put a real arrival window on every project before we start. Call (279) 300-1177 to schedule a free estimate and get the timeline for your specific scope.
We order Techo-Bloc material through our regular distributor and handle the lot-code matching and delivery scheduling for you. We also have working relationships with suppliers for KraftMaid, Cambria, and Silestone materials, so the interior finishes for your addition stay on the same written quote. You don’t order anything. The material arrives on our truck with the paperwork already reconciled.
Call (279) 300-1177 and we’ll spec the right Techo-Bloc line and quantity for your Sacramento job, then put the full number in writing.
