What Are ICF Foundations? (Plus Rough Cost Estimates)

nsulated Concrete Form (ICF) is becoming quite common in the home building industry. This innovative construction material is typically made of polystyrene foam blocks with gaps in between so you can pour a concrete wall.
You can use ICF for underground homes, basements, or entire multi-story houses. Moreover, you can start at the foundation and go all the way up to the roofline.

How Much Do ICF Blocks Cost? (And Where To Buy Them)

Insulated concrete form (IFC) is becoming a popular way to construct homes.
Previously, builders only used ICF for foundation walls. However, many companies are now going a step further and using them for the above-grade walls of one, two, and three-story homes. 
If you are planning to build with ICF blocks, the biggest question on your mind may be how much they will cost you.
