Techo-Bloc Home Additions & ADU: The Los Angeles Owner’s Guide
If you’re planning a home addition or ADU in Los Angeles using Techo-Bloc hardscape materials, the installed cost typically runs $53,100 to $153,400 depending on square footage, site conditions, and whether you’re building a ground-up ADU or adding onto the main house. We stock and install Techo-Bloc-compatible pavers, wall blocks, and steps for additions and ADU projects across Los Angeles, and we can usually match existing Techo-Bloc product lines so the new work looks like it was always there. Most homeowners discover a Techo-Bloc “part” failure not as a single broken piece, but as shifting, sinking, or cracking in the hardscape around a newer addition. Soil movement, drainage problems, and the freeze-thaw cycles Los Angeles occasionally gets in the foothills are the usual culprits.
Which Techo-Bloc Models This Applies To
Techo-Bloc manufactures pavers, retaining wall blocks, steps, and caps across several product lines, and the compatibility question matters more than most people expect. The most common lines we work with on Los Angeles additions and ADUs are the Blu 60 paver series (a smooth, modern paver with tight joints), the Para wall system, the Estate paver line, and the Victorien slab for larger patio areas. Here’s the gotcha: Techo-Bloc changes mold designs and color lots periodically, so a “Blu 60 Shale Grey” paver bought in 2019 will not necessarily match a 2024 batch of the same color name. We pull the actual paver ID and color code off the original paperwork or the underside of an existing unit before ordering anything, because matching by memory is how you end up with a two-tone patio. For OEM versus aftermarket, we install genuine Techo-Bloc products almost exclusively on additions and ADUs in Los Angeles. Aftermarket or big-box “Techo-style” pavers don’t carry the same dimensional tolerances, and that shows up as uneven gaps and lippage between old and new.

Signs Your Techo-Bloc Home Additions & ADU Is Failing
- Pavers sinking or dipping near the foundation of the new addition. This usually means the sub-base wasn’t compacted deep enough before the original install, or water is washing fines out from under the pavers. Los Angeles clay soil expands and contracts with moisture, and it will move pavers if the base isn’t built for it.
- Cracks running through multiple pavers in a line. A single cracked paver is a unit replacement. A crack line that jumps from paver to paver means the base has failed or there’s differential settlement under the pad. That’s a repair, not a patch.
- Gaps opening between the addition slab and the Techo-Bloc surface. This is common where the original hardscape wasn’t tied into the new concrete with proper expansion joints. Water gets in, soil swells, and the gap widens every season.
- Retaining wall blocks leaning or bowing outward. Techo-Bloc wall systems rely on geogrid reinforcement behind the wall for anything over about 2 feet tall. If the geogrid was skipped or under-spec’d, the wall starts to lean. In Los Angeles hillside lots, this needs attention before the rainy season.
- Efflorescence (white chalky film) that keeps returning. Some efflorescence is normal with concrete products, but recurring heavy deposits usually point to water moving through the pavers or blocks from a drainage issue. Fix the drainage, then we can clean and seal the surface.

AfterReplacement Cost & What’s Included
For Techo-Bloc hardscape tied to a home addition or ADU in Los Angeles, expect installed costs in the $53,100 to $153,400 range for full-scope projects that pair the addition with pavers, walls, or steps. Smaller-scope hardscape corrections like a paver patio replacement run $4,130 to $12,980, and a paver driveway runs $8,260 to $21,240. What drives the range: square footage, access for excavation equipment, whether we’re removing and hauling old concrete, the specific Techo-Bloc product line you choose, and whether the site needs new drainage or retaining walls before pavers go down. Every quote we write in Los Angeles includes the parts, labor, base prep, haul-away, and a written line-item price delivered before any work starts. There are no change orders that show up after we break ground unless you ask for a change yourself. The workmanship is covered by our 365-Day Done Right Promise, which means if the installation isn’t right within a year of completion, we make it right at no cost to you.

DIY or Call Us?
You can safely inspect a few things yourself before calling: walk the paver lines and mark any that have shifted, check for pooling water after rain, and look at whether downspouts are dumping water directly onto the hardscape. That’s useful information for us. What you shouldn’t attempt is lifting and re-setting more than a paver or two, or rebuilding any retaining wall over 2 feet tall. Retaining walls in Los Angeles are subject to city permit and engineering requirements, and a wall that fails can threaten your foundation, your neighbor’s property, or the people standing near it. If the hardscape has moved against your house or the wall is leaning, call a professional. If you’ve already got a Techo-Bloc patio that’s shifting, call us at (213) 632-5711 and we’ll tell you over the phone whether it sounds like a simple unit swap or a base repair, and what the visit will cost before we schedule it.
FAQs
A properly installed Techo-Bloc paver surface in Los Angeles should last 25 to 40 years before the base needs attention, and the pavers themselves are rated for decades beyond that. Los Angeles has the advantage of mild winters, but the clay-heavy soil in areas like the San Fernando Valley and parts of the Westside will test your base prep more than the pavers themselves. If the base was built right, the pavers stay put. Call us at (213) 632-5711 and we’ll take a look at what you’ve got before you commit to anything.
Yes, individual pavers can be pulled and re-set with fresh bedding sand, and individual wall blocks can often be replaced if the wall itself is still structurally sound. The real question is whether the underlying base or drainage is what failed. If it did, patching the surface treats a symptom, not the cause. We’ll give you a straight answer on which situation you’re in. Estimates are free, so there’s no cost to find out.
Most paver repairs, including removing and re-setting a sunken section, re-leveling the base, and reinstalling the same Techo-Bloc units, take one to two days once we’re on site. If we’re matching and ordering new Techo-Bloc product to tie into existing work, add lead time for the order, which varies by product line and color lot. We’ll give you a firm timeline in the written quote before work starts, and we don’t start until you’ve approved the price.
We source Techo-Bloc products directly through our trade accounts, which means we handle procurement, delivery, and color-matching for your Los Angeles project. We don’t ask homeowners to pick up pavers or wall blocks at a supply yard, and we don’t install customer-supplied materials on most projects because we can’t verify what condition the product arrived in. If you need hardscape that matches your existing Techo-Bloc, call (213) 632-5711 and we’ll identify the exact product line and color before we order anything.
