Cured-in-Place Pipe Rehabilitation Testing – Ensuring Quality and Longevity
Cured-in-place pipe (CIPP) has become a cornerstone of trenchless rehabilitation due to its ability to extend the life of aging infrastructure with minimal disruption. However, the success of any CIPP installation depends on rigorous testing — from the moment materials are selected through post-installation validation. Testing ensures structural integrity, verifies compliance with specifications, and ultimately safeguards long-term performance.
This article outlines the key types of testing associated with CIPP rehabilitation, focusing on pre-installation, during installation, and post-installation phases. Understanding and implementing proper testing protocols is critical for owners, engineers, contractors, and inspectors to deliver successful outcomes.
Pre-Installation Testing
Before CIPP installation begins, thorough testing is required to confirm that both the liner and resin meet the design requirements. This includes:
