Techo-Bloc Home Additions & ADU: The Long Beach Owner’s Guide
If you’re planning a home addition or ADU in Long Beach and want Techo-Bloc pavers, retaining walls, or slab systems incorporated into the build, the installed cost typically lands between $45,000 and $130,000 depending on square footage, site prep, and which Techo-Bloc product line you choose. We stock and install Techo-Bloc-compatible hardscape materials as part of our home addition and ADU projects, and we can usually match an existing Techo-Bloc paver or wall block within a few days of your initial consultation. Most Long Beach homeowners discover they need this service when they realize their existing Techo-Bloc patio or walkway needs to be extended, repaired, or re-laid as part of a larger build, or when a retaining wall shifts after heavy rain and starts pulling away from the new foundation line.
We’re an independent Long Beach remodeling contractor, not affiliated with Techo-Bloc, but we’ve been working with their paver and wall systems long enough to know exactly which products hold up in coastal soil and which ones need extra base prep. Before any price is written down, we walk the site, check the existing Techo-Bloc installation, and give you a written scope of work. No surprises after the crew shows up.
Which Techo-Bloc Models This Applies To
Techo-Bloc makes a wide range of products that show up in Long Beach home additions and ADUs, and the compatibility question is usually about matching what’s already on your property. The main lines we work with are:
- Blu 60 and Blu 80 pavers – These are the most common Techo-Bloc pavers we see in Long Beach driveways and patios. They come in 60mm and 80mm thicknesses. The 60mm is fine for pedestrian patios. The 80mm is what you need for a driveway that will hold vehicles, including a new ADU parking pad.
- Raffinato and Villagio wall blocks – Used for retaining walls and seat walls. These have a modular sizing system, so matching an existing wall means measuring the face height precisely. A 30mm face-height block will not interlock with a 45mm block, even if the color looks identical online.
- Greyed Nickel, Shale Grey, and Chestnut Brown color families – Techo-Bloc color lot numbers change over time. A paver bought in 2018 in Shale Grey will not be an exact color match to a 2025 production run, even with the same name. We flag this before ordering so you’re not surprised by a slight tone difference at the seam where old meets new.
The most important compatibility check we do is measuring the actual paver or block dimensions on your property, not trusting the product name. Techo-Bloc has changed the face dimensions on a few of their paver lines over the years, and a quarter-inch difference means the new pavers won’t lay tight against the old ones.
On the OEM-versus-aftermarket question: for Techo-Bloc specifically, we almost always recommend staying with genuine Techo-Bloc product, especially when matching existing hardscape. Aftermarket pavers from other manufacturers will never match the color, texture, or chamfer profile. The only exception is when a client is replacing an entire surface and doesn’t care about matching anything existing. Then a comparable paver from Belgard or Calstone can save 10-15% on material cost, but it’s a different look, and we tell people that up front.

Signs Your Techo-Bloc Home Additions & ADU Is Failing
- Pavers sinking or dipping around the foundation line of the new addition or ADU. This happens when the original base layer wasn’t compacted to Long Beach’s soil conditions. The clay-heavy soil in neighborhoods like Bixby Knolls and Los Altos expands and contracts with moisture, and a base that was fine for a patio won’t hold up under the weight of a new structure’s drainage patterns.
- Retaining wall blocks leaning or separating at the seams. Techo-Bloc walls rely on proper geogrid reinforcement and drainage gravel behind the wall. When water builds up behind the wall, hydrostatic pressure pushes the blocks forward. We see this most often on hillside lots near Signal Hill, where rain runoff moves fast.
- Paver edges flaking or cracking along a walkway that now carries construction traffic. Techo-Bloc pavers are dense, but wheelbarrows, material carts, and heavy foot traffic during a build will surface-spall a paver that’s already microfractured from tree root pressure or salt air. The coastal air in Long Beach is hard on concrete products over time.
- Efflorescence – the white chalky film – appearing on pavers that never had it before. This is a sign that moisture is moving through the paver differently than it used to, usually because the drainage path changed when the addition went in. It’s cosmetic, but it tells us water is pooling somewhere it shouldn’t be.
- Color fading unevenly across your Techo-Bloc surface. The UV exposure on south-facing Long Beach patios is relentless. UV-stable color is a Techo-Bloc strength, but older pavers from lines that have since been reformulated can fade differently than new pavers. If you’re extending a patio and the old pavers look washed out, we talk you through a pressure-wash and re-sand before we lay a single new paver.
Replacement Cost & What’s Included
For a home addition or ADU project in Long Beach where Techo-Bloc hardscape is part of the scope, plan on $45,000 to $130,000 depending on the size of the addition, the site conditions, and how much hardscape work is involved. A smaller footprint with a simple paver patio and one short retaining wall sits at the lower end. A larger ADU with a paver driveway, multiple retaining walls, and significant grading sits at the higher end. For a standalone ADU, Long Beach prices typically land between $90,000 and $220,000 when the Techo-Bloc site work is folded into the build.
Every quote we write in Long Beach includes a line-item breakdown so you can see exactly what the Techo-Bloc portion costs versus the framing, electrical, plumbing, and finishes. Our quotes include the base material, compaction, paver or block product, polymeric sand, and the labor to lay it. We don’t write change orders unless you add scope. The price Graham writes down on day one is the price on the invoice when we’re done.
We warranty our installation work for one year through the 365-Day Done Right Promise. The Techo-Bloc product itself carries the manufacturer’s transferable warranty, and we’ll help you register it.

Some parts of a Techo-Bloc project are safe to handle yourself, and we’ll be honest about that. Cleaning pavers with a gentle pressure wash, pulling weeds from paver joints, and checking for obvious drainage clogs are things any Long Beach homeowner can do. But excavating, grading, compacting base rock, and laying pavers that will support the weight of a new structure or vehicle is not a weekend job. A poorly compacted base under a paver driveway will sink within two seasons, and then you’re paying to tear it out and start over. A retaining wall above about three feet in Long Beach also needs a permit and engineered plans, and that’s not something you want to navigate without a contractor who’s done it in this city before.

FAQs
Techo-Bloc pavers installed on a properly compacted base in Long Beach typically last 25 to 40 years before needing replacement, though coastal salt air and intense south-facing UV can shorten the aesthetic life of the color to about 15 to 20 years. The paver itself won’t fail; the base will. If you’re seeing sunken pavers at year three, that’s a base failure, not a paver failure. Call (562) 512-7086 and we’ll tell you what we’re seeing under the surface.
In most Long Beach cases, yes – individual pavers can be pulled and re-laid, sections of retaining wall can be rebuilt, and sunken areas can be lifted and re-compacted with new base material. Full replacement is only necessary when the base layer has failed across the entire surface or when you’re changing the use of the area, like converting a pedestrian patio into a driveway that needs the thicker 80mm paver. We’ll always quote the repair path first if it’s viable.
The Techo-Bloc portion of a home addition or ADU project typically takes 3 to 10 days depending on square footage, base depth, and whether retaining walls are involved. This is sequenced into the larger project timeline, and we coordinate the hardscape work with the foundation, framing, and finish trades so the paver installation doesn’t get walked on by other crews mid-cure. You’ll have the schedule in writing before we start.
We source Techo-Bloc product through our Long Beach and Orange County supplier relationships and handle the ordering, delivery, and any color-lot matching with the manufacturer. You don’t need to order anything yourself. When a color match is critical, we request product samples and current lot inventory before we commit, so you’re not paying for pavers that arrive a shade off.
