Action Products Marketing Corp.

(APM) began rehabilitating manholes in 1975 with our patented PERMAFORM® system for replacement of manholes without digging and without interrupting flows. Our own crews were sent throughout the US to perform this unique solution. Cities soon realized that lining sewer pipes without sealing their manholes only transferred the problem but did not eliminate it. Manhole rehabilitation quickly began to receive the attention it deserved and project requests started to come in from all across the country. The workload began to exceed the ability of APM to keep up with this ever-expanding market with just its own crews. A network of affiliated contractors and representatives were soon organized.
