If you have radiant floor heating, it probably not a good idea to have a crawspace is it? Since the heat will travel down into the space where as if your foundation was concrete with earth under, the thermal mass is higher to plus you can add a high Rvalue insulation to further prevent heat from going downward.
@MonkeySpecs301 Actually I would say it depends on the area you are building in. Sometimes, particularly in colder climates, a crawlspace that had a well insulated floor assembly would be preferrable to putting a radiant floor system in the slab right next to the ground. heat escapes into the ground very quickly. This is evidenced by tile floored homes on slab in cold climates. I would think however if it is a fairly mild climate that slab is a good way to go.
Absolutely. The foundation will have to be designed for the neccessary loads ( this may mean deeper, wider footings, additional reinforcement, larger beams and/or larger floor trusses) but the crawlspace foundation can be used for multi-story projects no problem. Its important to remember that with any foundation, the weight of the structure should bear directly on or be transferred to the footings-whether crawlspace or slab.
@TheReturnOfStephan1 - Steel reinforcement is used almost universally in foundational piers. I don't think an I-Beam would be used, however, large rebar tied together into networks are often used. See the Building process video on slab reinforcement. The project we worked on had a number of piers in it because there were steel columns put in. You will see a lot of reinforcement in those piers.
this is so helpful! my husband and i are in the process of buying a house and i didnt know wat was the difference between a slab and crawlspace!! thank you soo much!!
Just digressing..dont slip near the rods.you'll get skewered!

@arossona Thanks for posting this video.
It's helping to clarify a lot for me, but, I do have a question regarding the piers.
Can galvanized i-beams, or something as strong, be encased into poured concrete or masonry forms as piers?
Will that make everything stronger, or will there be moisture issues, etc?
Thanks, in advance, for responding.

What about a foundation drain? What is the approved drainage system? That is THE MOST IMPORTANT part of the crawlspace!
