What Top Hat Lining Is
Top hat lining is a cured in place trenchless repair installed at the junction between the sewer lateral and the main line. The liner forms a reinforced collar that seals the connection and restores structural integrity at the joint.Top Hat Lining Installation Process
The process begins with sewer line cleaning and camera inspection to confirm the condition of the lateral connection. A resin impregnated top hat liner is positioned at the connection point using specialized equipment.UV Light Curing Process
Once the liner is properly positioned, UV lighting is used to cure the liner in place. The ultraviolet light activates the resin, hardening the liner and creating a durable, watertight seal at the sewer lateral connection.When Top Hat Lining Is Recommended
Top hat lining is recommended when the lateral connection is cracked, leaking, or allowing root intrusion, but the surrounding pipe structure remains suitable for lining.Common Problems at Sewer Lateral Connections
