Laterals all lined up: Test layout at the IKT large-scale facility

Damage to the lateral connections on main sewers is a frequent occurrence. Common types include intruding and detached damaged connecting lines and cracks and/or spalling around the lateral connections. Injection and top-hat section methods for the repair of sewer lateral connections have been tested to the limit in an IKT Comparative Test. The assessment criteria were the system tests performed by IKT in test lengths, the method suppliers’ Quality Assurance measures, and on-site tests.
