what type of sleeves do you normally use for the utility penetrations (size/material)?

Thanks,

We typically use a piece of PVC pipe of the appropriate size. Works well for most apps.

thanks for the quick reply. What thickness would you normally use for electrical entering the house, cable, phone, well supply, and the natural gas line?

Thanks,

Brian, the smaller diameter holes are drilled very easily and the larger than 2" are usually sleeved into the home pre-pour. If you are doing this project your self I would recommend all sleeves to be a 1" larger than necessary to accommodate a fudge factor and also in case your fall (to outside) gets pushed out of whack by the pour. You just simply run any lines thru the larger sleeves (less couplers also) and spray foam them shut above grade, or water-stop them below.

Just curious what the recommended water-stop below method is. My local IntegraSpec distributor indicated that I should spray-foam them shut below and then use a thinly-spread caulking as a water stop at the outer or inner edge. He didn't like the idea of using a hydraulic cement product for some reason. Thoughts?

I find it hard to believe anyone associated with one of the better names in ICFs would suggest CAULKING????? Perhaps they meant one of the liquid waterproofing products??

Hydraulic cement has issues if you attempt to use the foam as a bed for the cement, the only way it will work correctly would be to remove the foam in order to get to the concrete wall.

James E , and ICF fam:I agree with James the method of spray foam and caulk is a bad idea. Depending on how you placed your drains etc threw the wall it would depend on how to finish. If you sleeved with a larger sleeve the water stop works excellent. As to Jims reply the methods recommended with the water stop was for smaller pipes running threw a larger sleeve. Either way you do it cut a piece of peel and stick 1' x 1' and cut a hole in the center 1' smaller than your pipe. Next cut a slit from one side center to the hole and place over the pipe with the slit up. Next cut one 18'' x 18" same hole and slit and install with the slit down.
