Action Products Marketing Corp. (AP/M) began rehabilitating manholes in 1985 with its patented PERMAFORM® system for replacement
of manholes without digging and without interrupting flows based on its earlier technology patented in 1976 for pouring new manholes
in place. Its own crews were sent throughout the US to perform this unique solution. As cities realized that lining sewer pipes
without sealing their manholes only transferred the problem rather than eliminating it, manhole rehabilitation received the attention
it deserved and work exceeded the ability of AP/M to satisfy this expanding market with its own crews.
AP/M believes that successful rehabilitation requires quality products coupled with quality workmanship. The only way to accomplish
this was to find contractors to perform to the same high standards that AP/M set for itself … to train and to license local
installers in its unique technologies. AP/M set about to train and to certify more than forty regional applicators throughout the US and the World.
Recognizing that not all manholes need complete replacement, AP/M developed its high strength, centrifugally spun PERMACAST
system to seal and reinforce damaged structures. Its unique delivery equipment enables uniform thickness control and very
dense compaction without the need for hazardous confined space entry. Quality is assured with pre-measured factory mixes
for guaranteed consistency in the field..
