Foundation walls using ICFs-how to estimate cost?

palmcityflMarch 27, 2010

Estimates I've gotten for precast foundation walls (Superior Walls, Ideal Foundation, Intl Precast) range from $8 to $10 per lineal foot for a 10' wall. Foundation walls built with ICFs should be less. Polysteel ICFs range from $1.50 to $3.50 per square foot for the forms, not including labor and materials. For a 1600 SF foundation built with ICFs, what should I expect to pay?

STAY AWAY from Superior Walls - they don't guarantee their product - and do you want a paper-thin sheet between you and water? ICF's price vary with the brand name, but you can negotiate a lower price. I'm building with an large addition with all ICF - but when I was planning I was considering SIPS (it was coming in much cheaper). The ICF guy negotiated with the manufacturer and got me a matching price. Have some guys out, tell them what you can get from someone else, and watch them scramble.
