Is made up of snap together, two foot wide by 6" thick panels, with cut-to-the-inch lengths, that makes for quick installation. This concrete wall FORM system offers a non-porous, prefinished, bright white surface on both sides, reducing finishing and installation time, while providing a easy to clean sanitary solid structural wall. Specifications , More Details, Video page .
