  1. Poly foam 5 lb two part 5 Star Review

    Posted by on 2nd Mar 2015

    This is great for repairs and support

  2. Works Great 5 Star Review

    I used this for a shower pan that have been improperly installed and it worked great. Hardly any mess, (follow the instructions!), and the pan bottom is rock solid now. I would recommend this to anyone.

  3. Incredible Floor Support 5 Star Review

    Posted by on 20th Sep 2012

    In the last 6 months I have done several major floor repairs that I would have refused to attempt in the past. If used wisely and according to instructions, this high density foam
    is incredible. I repaired a tub with a broken bottom board last month, pulled up the bottom board with a drywall screw and injection foam under the board. The homeowner (375 lbs.) is thrilled that he does not have to replace the tub.
