Hello everyone. I am so glad that I happened to stumble upon this great site. It has been very educational and helpful. We are hoping to build our 2000 sq foot home next spring.
My first question is how strong is an ICF foundation compared to a conventional foundation? My builder is trying to talk us into building an icf home but with a conventional foundation as he believes it is stronger.
My second question is... I know that we will save a lot of money in heating by going with the icf and also if we were to go with geothermal. My concern is...will we save enough to make up for the cost of both?
We originally wanted to go with icf, geothermal and infloor heating but our builder estimated that it would cost us around $70, 000 more for all three which we would not get back enough in savings to make it worth it.
Thanks for your time.

Is your builder talking about using a conventional poured concrete or cmu foundation below grade and then switching to ICFs above grade? If so, that's just plain dumb. In my experience, an ICF vertical wall assembly is much stronger than either equivalent thickness poured walls or filled cmu.
Without more detailed info, I would not think that spending the additional $70,000 would be worthwhile.
How do the additional features breakdown, cost wise? |

If conventional foundations in your area are CMUs, then Flat panel ICf systems( 90 % of the systems out there, is way more stronger. If a regular poured wall system is conventional in your area (take the wood or metal forms down the next day or so) then flat panel ICFs are again way more stronger (That's Kentucky talk for: "way mo betta"!!)
Reason being is that when an icf wall is poured and is curing, the EPS panels stay in place and a slow moist cure is taking place allowing the 3500-4000 psi concrete to cure out at 5500 or more in 28 days.
Hope this helps. Listen to Wes |
