Secure Set foam is an alternative for concrete for setting posts in the ground. It is intended as a faster, cleaner and easier-to-manage replacement for concrete, especially in small residential building or improvement projects. Each kit contains a shake-and-pour container and two chemicals. When mixed together and poured into a hole, the mixture quickly dries and reduces the need for heavy lifting and extensive equipment. It is a high-density foam that is compatible with wood, metal and vinyl posts.
