RE: Sleeve through footing

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I have seen SDR PVC used, 1" bigger all around the pipe, split in half then duct taped together. One problem with this method is to assure the 1" clearance all around is maintained. Thomas's idea is better for that reason, assuming you can find a thick enough piece of insulation.

Couldn't you just use some Styrofoam pipe insulation from Home Depot that is already split and just slides on over the pipe.  It is stiff enough to act as a form for the concrete but pliable enough to provide limited movement.

Sleeve through footing

I have an existing pipe running through a proposed footing.
What is a good means to sleeve the pipe?
Thank you,
