Description

BuildBlock ICF Benefits

  • Ready to Stack.No on-site assembly required; start installing right off the truck.
  • Fully Reversible.All forms are fully reversible; no top, bottom, left or right. Longer corner design provides automatic offset for each course.
  • Industry Standard Size.Industry-standard 16-inch (406.4mm) high forms produce less waste when cutting around doors and windows.
  • Tight Interlocking Blocks.Blocks easily stack and securely lock into place resulting ingreater strength over the competition. No foam, clips, or ties required between courses.
  • Foam Panels.Allows easy accommodation of electrical and plumbing installations.
  • Open Web Design.Interior rebar saddles provide rebar support without compromising concrete flow.
  • 2.5-inch (63.5mm) Foam Panels. Allows easy accommodation of electrical and plumbing installation inthe foam.
  • Strongest interlocking connections for greater stability and precision alignment.
  • Built-in 1-inch repeating interlock pattern reduces waste.
  • Integrated numbered vertical cut lines & Molded horizontal cut lines.
  • High-density plastic web molded into place every 6 inches on center for easier attachment of studs, cabinets, and other finishes.
  • Patented and award winning technology.
  • High-density Plastic Webs on 6-inch centers. Greater strength, more value.
  • Deep Rebar Support locks in place and allows full contact laps and eliminates most steel tying.
  • Easy mechanical chases for plumbing and electrical.
  • Open Web Design for efficient concrete flow and half-height block support.
  • Molded-inTape Measure and Horizontal Cut Lines.
  • 1-inch Repeating Cut Pattern on Block Connection.
  • Lowest waste of any ICF on the market today.
  • Attachment Point Markings
  • No special half-height blocks required.
  • Embedded 15″x1.5″ standard attachment points every 6-inches function as studs with 150lbs. pullout strength.

Key Advantages

  • Molded-in “Tape Measure” and markings identify attachment points.
  • Numbered, vertical cut lines every inch, often eliminate the need for using a tape measure.
  • Extra Heavy-duty “BB” Attachment Points (450lbs.+) located every 8″ vertically and every 6″ horizontally, allowing for super secure attachment of bracing or heavy cabinetry.
  • Attachment Point Markings
  • Heavy-duty attachment points are marked with a BB. Molded-in Horizontal Cut Lines. Located every two inches; provide horizontal cutting references for straighter cuts.
