Description

Description

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.

4" BuildLock KD Web Bridges come 256 per box

Why BuildLock Knockdown

  • Available in 4”, 6”, 8”, 10”, 12” or greater core widths.
  • BuildLock’s patented web is the strongest web on the market.
  • Double-reinforced corner webs on 10” and 12” forms for safer pours and more attachment points.
  • Expandable core for larger sizes (24”+) with optional bridge connectors.
  • 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 an optional bridge clip connector.
  • Integrate pilasters into ICF walls.
  • Create insulated footings and foundations.
  • Designed to easily allow 8” horizontal rebar spacing in large commercial projects.
  • Tilt up & retrofit insulation applications.
  • On-site assembly for integration of pre-set penetrations such as blast-proof door and window frames.

BuildLock ICF Benefits

  • Fully reversible blocks and webs.
  • Numbered vertical cut lines every
  • 1-inch and horizontal cut lines every 2-inches.
  • Tight interlocking blocks with 100% surface-to-surface connections eliminating costly ties and accessories.
  • High-Density Plastic Webs with 2 Extra Heavy Duty Attachment Points (450lb.+ pullout) on each web.
  • Form and insulate in one step and use any finish application including BuildBlock Hardwall.
  • 4-hour fire rating and low sound transmission.
  • Fully integrates with all other BuildBlock ICF Products.
