sanitary structuresPermatile manufactures standard sanitary mahole structures in 48″; however, we also build in 60″, 72″, 84″, 96″, 108″, 120″, and 144″.

To facilitate and minimize site construction, preformed butyl resin sealant for fast, watertight assembly is standard with our manholes. Monolithic bottoms, preformed inverts, steps, enclosed lifting inserts, and a variety of flexible manhole-to-pipe couplings provide a quick, economical, high-quality installation. Interior or exterior coatings or linings are available for corrosive environments.

We offer many manhole structures

We build standard manhole structures, drop manholes, leachate manholes, and custom manholes.

Pipe to manhole connectors can be provided to accommodate pipe sizes from 1 1/2″ up. We also furnish castings for most requirements.

Our standard 48″ sanitary manhole sections are vacuum tested at our plant prior to shipment to ensure performance on the job. In all applications, our warranty applies when structures are tested according to ASTM C1244, Negative Air Pressure (Vacuum) Test. This procedure requires testing before any backfilling occurs.

Quality to meet specifications

Our precast manholes meet or exceed ASTM 478 and applicable AASHTO specifications. Gaskets for pipe meet ASTM specifications C-443 or C-361.
