The Engineering challenge – Since the inception of foam-filled products like boats and surfboards, to modern day aircraft applications, the problem with two-part structural foams has been that they expand quickly and uncontrollably when mixed and require large holes for “the pour”. In addition, they do not address the issue of accumulated moisture, or varying levels of moisture in the deck cavity which also cause the foam hardness to vary. The more water, the more expansion, and hence lower density, making other foams unsuitable. Once cured, Injectadeck is a hard and resilient structural foam (consistency like wood) that can support heavy loads with little or no collapse of the closed-cell waterproof structure. Expanding six to eight times its volume, it’s a dense foam which you could dent…with a hammer. Most boat decks, particularly older ones, are wet rotted and perfect candidates for this product. With Injectadeck’s latest formula and process we are able to adapt to all voids wet and dry resulting in a solid deck you can feel good about. The more water you drain out the harder the foam density.
