Urethane foam will emit toxic gas when cut with a hot wire cutter.

So do you carve a handhole pocket out of a solid block, or mold the styrofoam with a handhole pocket built in?

I wonder if you could mold your own out of polyurethane foam.

Google direct buries most of their splice enclosures with a locate ball.
 
I am thinking of making a large cube of styrofoam that has a pocket for the splice case.
Direct bury it all with a locate ball.  Need back in, just cut the sod and pull out the styrofoam.
 
The strength of a block of styrofoam is in the same range of firm to stiff soil. 
Lot less money than a handhole.  You could use a hot blade and cut it up to get it out if you needed the slack coil.

I've been using the Carson / Oldcastle 2200-18 vaults with a 6" extension, but everything is backordered 30+ weeks.  Does anyone have any alternate suggestions for a vault to hold a FOSC 450A  splice closure? HDPE would probably be preferable, but I could do a concrete polymer if necessary.
 
Thanks.
