I have a trapped area with an irregular shape. It has a thin aluminum skin on one side and angle iron on the other. The area isn't entirely trapped and there are small escapes surrounding the void (multiple small flashing points). I thought using Alumifoam would be an appropriate material as the material it is replacing used to be wood....now rotted wood.
One section has a vertical void about 12" tall. the question is...does Alumifoam create tremendous pressure before skinning or does it continue to seek out voids then seize up quickly? I'm trying to avoid bulges in the aluminum skin.
The other question...bolts pass through the void. Would it be better to provide a sleeve, drill the foam or place the bolt in place and allow the foam to cure around it...using a release on the bolt.
Does Alumifoam form a case hardened skin and how thick is the skin...or is it the same density throughout?
If I make several small pours will the Alumifoam bond with itself on subsequent pours?
