Description

This WaterMark Technical Specification sets out requirements and test methods for cured-in-place pipes used for the rehabilitation of above and below ground non pressure drainage and sewerage pipelines.

Scope

This Technical Specification sets out requirements and test methods for cured-in-place pipes (CIPP) used for the rehabilitation of above and below ground non pressure drainage and sewerage pipelines.

The CIPP consists of a resin system in combination with a compatible fibrous/woven material which is installed within the damaged pipeline, inflated against the pipe substrate and cured in place filling any cracks and voids.

The process may be applied to metallic and non metallic non pressure piping systems in pipe sizes DN 40 to DN 1000 in the rehabilitation of existing pipe work in the field above and below ground. These products require certification to WaterMark Level 2.
