An alternative method to build foundations and walls. ICFs are parallel sheets of foam joined by small connectors to leave a large gap between the two (usually around eight inches). ICFs are stacked and then concrete is pumped into the cavity to create the foundation or wall. Used in both residential and commercial applications, ICFs have several advantages over traditional construction including strength; durability; safety; energy efficiency via improved insulation; and resistance to insects, mold, rot, and mildew.
