Title: Cured in Place materials and system quality assurance based around a performance specification and site evaluation

Speaker: Mr.Ian Ramsay, Vice-chair, UKSTT


Cured in Place Pipelining (CIPP) has been around for circa. 50 years. Many thousands of kilometers have been installed successfully around the world since then. Standards such as ASTM and EN/DN have been developed to cover the quality, performance, and strength of the final product. CIPP is not suitable in every case for rehabilitation but is a valuable tool in the box of trenchless techniques.

Various different materials used in CIPP are available from a standard coated felt construction to reinforced layers. Resin technology has developed with various hybrid resins now available in addition to the standard polyester resins, whilst curing methods from ambient to hot water, steam, and UV/LED has also developed over the years.

Identifying the right system or choosing the right materials and processes can be very confusing when looking at a project.

In this webinar, we will explore the factors around the selection and specification of a CIPP solution which is fit for purpose. It will cover:

  • Who can specify a CIPP solution
  • How a performance specification is developed and executed.
  • The key factors in the selection process of the materials and curing system.
    We will also look at the project execution itself and QA/QC regarding the setup, time constraints and various key factors to determine a successful installation and client handover.
