Perma-Liner Industries has announced the release of InnerSeal, an engineered solution for repairing defective laterals and the connection to the mainline.

The technology was designed using the standard practice for the rehabilitation of sewer service laterals — ASTM F2561-11. InnerSeal is a one-piece, structural and continuous main-to-lateral CIPP that completely seals the connection while simultaneously renewing the lateral.
