Storm Structure Systems

From standard highway drainage structures to the most complex custom designs.

Permatile manufactures a variety of precast concrete drainage structures to meet the needs of the many engineers, municipalities and state DOT’s that we serve on a regular basis. Structures include catch basins, curb inlets, area drains, drop inlets, junction boxes, energy dissipators, spring boxes, BMP’s, end treatments and knock out boxes. Structures can be manufactured with watertight gasketed “pipe to structure” connections. Permatile provides castings, hatches, steps and other fittings to suit your contract needs.
