Everything you want
to know. Upfront.

An interlocking concrete block engineered to stack without mortar. The male-female geometry locks horizontally and vertically. Pre-routed channels carry plumbing, electrical, and data. Each block weighs about 6 lbs so a single person can handle one without lifts.

Traditional CMU needs mortar (skilled masons), rebar grids, and concrete infill — 3 separate skilled trades and ~3 weeks for a single-family shell. Lok-N-Blok snaps together: 2 people, 2 days of training, one week to shell.

Higher compressive strength, 250 mph wind rating (vs ~150 for standard CMU), no mortar joints (which are the weakest point in any concrete wall). Installs 2× faster with unskilled labor.

Concrete core, Class A fire rating. A Lok-N-Blok wall won't ignite, won't feed the fire, and passes standard 2-hour rating tests.

Concrete doesn't host termites, feed mold, or rot. The fundamental problems with wood-frame construction simply don't exist.

Yes. Integral color (not paint) in gray, sand, white, and custom blends. You can also stucco, paint, or side over it — nothing about the finish changes once walls are up.

Not for typical residential. Structural connections come from the interlock geometry plus anchor bolts at foundation and roof tie-downs. Commercial and multi-story projects use supplemental reinforcement per stamped engineering.

The block has R-14 baseline. Add integrated foam inserts for R-28, or exterior continuous insulation for R-40+. Meets every US climate zone.

Any licensed GC or ambitious owner-builder with basic carpentry skills. Our 2-day certification covers foundation prep, first-course alignment, corner geometry, door/window bucks, and roof tie-down. Crews we've certified are now installing ~4 homes/month.

Shell (exterior walls, roof tie-down, dried in): 5–9 days for a 2,000 sq ft single-family. Full close-out with MEP + finishes: 8–12 weeks vs 16–24 for equivalent stick-framed construction.

Yes for ADUs, tiny homes, and single-story builds. We recommend a certified installer for multi-story or any project your AHJ will inspect carefully. The 2-day training is cheap insurance.

Rubber mallet, level, tape, chalk line, impact driver. No framing nailers, concrete mixers, or specialty masonry tools. Everything fits in a pickup.

Factory-routed channels inside each block. Your MEP plan slots in the channels at design time (our AI does this automatically). Rough-in is hours, not days.

Standard framed bucks drop into openings. Our system accommodates any off-the-shelf window/door unit. No special trim carpentry.

Yes — reserve at /preorder.html. No deposit required. You'll lock early-adopter pricing and a Q1–Q2 2027 production slot.

No. Your reservation locks today's pricing. Public pricing will step up ~15% at launch; you pay the locked rate on your final invoice.

$150K–$220K turnkey for the block system, labor, and core finishes. Add site prep, foundation, and interior finish per your local market. Total build typically 30% below stick-framed equivalent.

We partner with construction lenders familiar with alt-material builds. Check our mortgage calculator for rates, or mention financing interest on the preorder form and we'll connect you.

Blocks are reusable — you can disassemble a Lok-N-Blok wall and rebuild with the same material. End-of-life carbon footprint is a fraction of concrete or wood. Details on our solutions page.
