During a recent Contech reline webinar and following question and answer session, I realized there were several great questions asked about Reline Grouting. It made sense for me to address some of those here, hoping the responses provided might prove helpful to an extended audience. Hopefully, you agree!   WHAT TYPE OF GROUT IS RECOMMENDED AND IS

I often receive questions on how to properly design a reline project, from assessment and hydraulics to structural design.  I thought I would take time to discuss one involving the latter in particular.QUESTION: I am doing a reline of a 60" diameter storm sewer. There are a lot of structural design methodologies being touted by various product
