V-lock concrete blocks seat into each other with a V-shaped key and stay put by weight alone. We supply them to contractors and public works nationwide, matched to the closest production facility.
The V makes the difference
A raised V on one face meets a matching groove on the other, so each unit seats into the one below. That stops blocks from sliding outward under the weight of backfill.
No mortar, adhesive or special connectors.
Poured to a set mix design, never from leftover truck washout, so joints do not shear.
Reinforced loops or recessed points for a crane or a forklift attachment.
The 2′ x 2′ x 6′ block is the standard for stability and coverage.
| Spec | Detail |
|---|---|
| Standard size | 2′ x 2′ x 6′ |
| Approx. weight | about 3,500–4,000 lb, depending on mix |

Walls that hold heavy soil, handle grade changes and stabilize ground for the long term.
Bays, bunkers, recycling centers and scrap yards that take daily loader impact.
Temporary or permanent barriers whose mass keeps them in place when water moves fast.
Highway work, bridge approaches, municipal and utility projects that need long service life.
Detachment 5 LLC is service-disabled veteran-owned and registered in SAM.gov, so agencies and prime contractors can buy from us directly.
Every quote is built for the specific job, with freight included up front. We pair the job with the closest high-output production facility to cut freight cost per block.
Lead times depend on order size, the production schedule and distance. You get dates up front so you can book crews.
They can be either. Use them for permanent structures such as sea walls, or as temporary modular walls that can be taken apart and moved when the site changes.
Yes. We coordinate supply across the United States and match your job with the nearest production facility to keep freight manageable.
No. The V joint is made for dry stacking. The interlock plus the weight of each block makes a secure connection by gravity alone.
A standard 2′ x 2′ x 6′ block weighs about 3,500–4,000 lb depending on the mix. We confirm the weight for your order.
Heavy equipment: a large forklift, a skid steer with enough rated capacity, or a crane for safe handling and exact placement.
