Hello,

I need help finding a product that can insulate T-branches which are already burried underground. T-branches looks like:

Currently we use a primer, mastic, rubber band made from butyl and polyethylene. Due the geometry of T-branch, rubber band (tapes) are hard to apply. So we looking for a product that can be applied with brush (like a paint). We tried HBE95 from Canusa and Carboguard104 from Carboline, but both failed when we checked with Holiday Detector ISOTEST.

Any suggestion?

Kind regards,
Mike
