For over 40 years, APM has produced high-quality
products for sewer line repair and seamless
manhole concrete pipe restoration. The Permaform
system and resourceful solutions make it easy to
replace manhole concrete pipes without having
to excavate and negatively affect the structural
integrity of the area.
To simply reinforce and seal the pipe liner of
a brick or concrete drainpipe or sewer pipe, we
carry our specialty Permacast Mortars. The unique
CentriPipe system provides waterproofing, sealing,
structural reinforcement, and corrosion protection
for sanitary and storm culverts without trenching,
while providing savings.

SpectraGrout is a single component, hydrophilic
polyurethane resin designed to repair cracks, seal
around pipe penetrations, open joints and stop leaks
in wastewater structures. The resin is a high-viscosity
formula that reacts with water to create a dense
foam, assuring that the grout will not readily flow out
from the point of placement. The foam solidifies in
minutes, stopping the leaks and filling the voids.
The product is available in tubes, 5-gallon pails
and 55-gallon drums. For superior performance at a
lower cost, try SpectraGrout.
