FAQ – Do All Methods Require Grout?

Transcript from Video

Do all Spiral Wound methods require annular space grouting? The answer is no. We offer solutions from 6” all the way up to 60” that do not require annular space grouting. These two products are SPR™EX and SPR™TF.

SPR™EX expands to fit tightly against the host pipe wall while SPR™TF is wound in directly against the host pipe wall. Our large diameter method, SPR™, is the only Spiral Wound process that requires annular space grouting.
