10″ 90º Bl KD Corner Block – 8/bundle
$425.00
The BuildLock Knockdown ICF System is a high performance knock-down insulating concrete form (ICF) wall system comprised of two separate 2½ inch Expanded Polystyrene (EPS) panels which are connected by strong, high-density plastic webs on 6-inch centers. BuildLock is the strongest knock-down product on the market today.
Each web bridge features a 3-axis positive locking attachment that snaps the web securely in the proper position to eliminate racking and provide superior structural stability throughout the construction process. The BuildLock Knockdown block exceeds even the superior strength of BuildBlock ICF blocks.

- Blocks ship flat to reduce shipping costs and increase product storage capacity.
- Larger rebar saddles for multiple rebar sizes.
- Reinforced web flanges for additional strength.
- Simple, quick on-site assembly.
- Completely reversible webs for multiple rebar locations and 8” horizontal spacing.
- Connect multiple webs for special construction needs such as pilasters.
- Use BuildBlock Hardwall to create an ICF wall with bare concrete on one side.
Knockdown Advantages
- Commercial ICF block for projects requiring 4” to 12”+ concrete cores.
- Patented strongest ICF web design on 6” centers.
- Build 4”-24”+ walls using optional bridge clip connector.
- Integrate pilasters into ICF walls.
