Pottsy,

I don't know but I will find out. I need to know too. I'll find out how much is used customarily to float a particular width etc pier.

I first found out about this foam from a taxidermy supplier in Idaho. I was told it worked great to carve fish bodies for taxidermy, and he said it was commonly used for floating piers in his area.

I may have my pieces shrink wrapped for extra protection or breakdown, even though the billets will be under the pier.

Remember I don't believe this is the regular construction foam. It's about 8 feet long and I believe it was about 2 feet thick or more (I don't have any right now as I now use a softer foam for carving fish bodies).

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
