I have a 16'x5' flatbottom Alumaweld. On the weekend I lifted the floor up to find the foam was soaked with water. I took out the easy to get at foam along the sides (wieghed about 150lbs), but the foam the has been injected under the box girders is also soaked and I can't get at it to cut it out. Does anybody know of any way to dissolve or remove this foam without cutting into the box girders. Also , should I replace this foam and if so with what? I tried to find an e-mail address on th eAlumaweld site but could not find one, so hopefully some here has a solution.
