Final Work, Acceptance, Renovation Defects

Site Sampling and Test Sample / Specimen (2)

In the case of accessible cross-sections, the sample is preferably taken within the section. If the sewer to be rehabilitated has uneven surfaces (masonry, corrosion), the intended sampling point must be smoothed before installing the lining tube.

The samples are to be removed from the CIPP liner in a thermally gentle manner (i.e. carefully avoiding local heating at the point of separation) in such a way that the entire thickness of the CIPP product is recorded representatively. The resulting defect in the CIPP liner should be repaired with comparable materials and by a procedure documented in the installation instructions.
