Base Liners

Predl Manhole Base Liners provide complete protection from corrosion and abrasion. The one-piece molded liners incorporate accurate invert elevations and smooth flow surfaces to eliminate turbulence. Integrated watertight and flexible pipe connecting bells are aligned to the correct slope and angle with funnels trimmed flush to the outside diameter of the concrete form.
