Icon FastFoam is a revolutionary two-part urethane expanding foam that activates instantly. It can be injected from the inside towards the outside of sumps at the point of water ingress using a simple applicator nozzle, creating a temporary seal within seconds. This rapid action allows for more permanent repair and treatment of active water leaks without the need for large pumps to lower the surrounding water table—a process that not only is cumbersome but also incurs significant costs. FastFoam represents a practical, cost-effective solution to immediately address leaks, facilitating a smoother transition to long-term repair measures.
