MagnaPlast™ is a factory-assembled HDPE sewer manhole system engineered to resist corrosion, reduce installation time, and deliver long-term performance with minimal maintenance in sanitary sewer environments.
ABOUT MAGNAPLAST™
A New Standard for Sewer Infrastructure
MagnaPlast is Houston Polytank’s flagship HDPE sewer manhole system, designed to outperform conventional concrete manholes in corrosive sanitary sewer environments while remaining nearly maintenance free over its design life.
Its one-piece, factory-assembled construction helps municipalities, engineers, and contractors reduce leakage risk, simplify installation, and improve long-term reliability.
