What Is a Top Hat Sewer Liner?
A Top Hat Liner Repairs a Connection Rather Than the Full Line
A top hat liner is a localized trenchless repair used at an eligible connection between a smaller lateral pipe and a larger sewer line. Its shape includes a short sleeve inside the main line and a brim that seals around the connection, which gives the liner its “top hat” name.
The process begins with a sewer camera inspection and preparation of the connection. If the pipe geometry and condition are suitable, the liner is positioned and cured in place to help seal the joint without opening a continuous trench.
A top hat liner is designed for a specific connection; it is not a full-length lining method or a solution for every type of damage. Cracked, collapsed, severely misaligned, or extensively deteriorated pipe may require broader sewer pipe repair or replacement.
