V-lock concrete blocks lock together with a V-shaped key and stay put by weight alone. We supply them to contractors and public works projects nationwide, matched to the closest production facility.
A V-lock block has a raised V on one face and a matching groove on the other. Stack them and each unit seats into the one below, which resists sideways force far better than a flat-topped block.
The male-and-female profile locks every block in place and stops units from sliding outward under backfill.
No adhesive, mortar or special connectors. Dead weight and the shape of the joint keep the wall stable, which cuts labor on site.
The same unit builds a low material bin or a tall containment wall. It is the go-to block when a design calls for a gravity wall.
01
Walls that hold back heavy soil, handle grade changes and stabilize ground for the long term. The V keeps blocks from sliding under the weight of backfill.
02
Aggregate bays, storage bunkers, recycling centers and scrap yards. The blocks take daily loader impact and the weight of gravel, sand and salt.
03
Temporary or permanent flood barriers and emergency protection for infrastructure. Their mass keeps them in place when water moves fast.
04
Highway work, bridge approaches, municipal developments and utility projects where long service life is required.
V-lock systems come in modular sizes. 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 |
| Concrete | Commercial-grade mix, 4,000+ PSI |
| End units | Half blocks and corner units are often available |
| Handling | Reinforced lifting loops or recessed pick points |
Some blocks on the market are cast from leftover concrete washed out of ready-mix trucks. Ours are poured to a set mix design, so the V joints do not shear or crumble when the wall is loaded.
Each block has built-in pick points, so crews can set it with a crane or a forklift fitted with the right attachment. Plan for equipment rated for multi-ton loads.
V-lock concrete blocks are chosen when a wall has to hold heavy aggregate, water or soil without moving.
Made to take the side pressure of piled aggregate and the wear of an industrial yard, day after day.
Each block is cast to a uniform strength, which gives every course the same load capacity.
From replacing a single block to supplying a large civil project, we have the capacity to fill it nationwide.
Once stacked, the V profile stops blocks from shifting, which is why it is preferred for tall, heavily loaded walls.
A few checks before the first truck keep the install on schedule.
A standard flatbed carries 40,000–48,000 lb, which works out to about 8–12 six-foot blocks per load. We plan the number of loads with you.
Have a large forklift, telehandler or crane ready, rated for multi-ton picks. Blocks arrive with pick points for standard rigging.
Trucks need clear entry and exit and firm ground at the drop zone. The wall itself needs a level, compacted base before the first course goes down.
We deliver V-lock concrete blocks to job sites, yards and infrastructure projects across the United States, in bulk loads planned around project size, timing and site access.
We pair your job with the closest high-output production facility to cut freight cost per block.
Municipal job, yard expansion or wall build: we schedule hauls so blocks arrive when your equipment is ready to set them.
Delivery location, estimated quantity, application and timeline. Active jobs and bulk orders are priced first.
Every quote is built for the specific job, with freight included up front so there are no delivery surprises.
On heavy civil work, a block is only as good as the supply behind it.
Detachment 5 LLC is registered in SAM.gov (UEI HL1RV4KVLN33, CAGE 81SM4), so public agencies can buy from us directly.
Every block is poured to a mix design. No washout or leftover concrete.
No need to ask where we are located. We source from the plant closest to your job.
No dealer in the middle, so you get faster answers and lower overhead.
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.
