Expanding foam agents
Expanding foam agents
(OP)
I need a simple and cheap way to fill a large hole (1m3)with something like polystyrene. Are there any chemicals that I could mix that would expand and fill the void inexpensively. The material must harden so that it could be removed at some point. The material could have bubbles in it but preferebly <1-2mm dia voids maximum. Just looking for a simple way not really wanting to use a gas mixing system unless this is very easy and reliable. Would also be great if you could tell me how many buckets of each chemical would be required to fill the hole. Thanks

If you are trying to fill 1m3, the rigid foam will be density 0.02 or so; you would want to make it in several batches. Better, get a commercial insulating contractor to do the job; he will have the tools to mix and apply it safely.
