Seawall stabilization with Prime Flex 920 polyurethane foam

Prime Flex 920, a rigid structural polyurethane foam, is used to stabilize a seawall below a row of houses in Washington. The contractor injected 920 into voids behind the seawall using probes. There were massive voids. Erosion had caused significant cracks in the stone wall. Prime Flex 920 polyurethane foam fills voids and seal cracks or failing joints. Installation using a probe means no disruptive excavation. This material is certified to meet NSF/ANSI Standard 61 for contact with potable water, so this is an eco-friendly solution as well.
