Earthenware pipe repair/ join to PVC

[Traveller]

Looking for a glue/sealant to bond a PVC pipe into an old earthenware (clay) pipe. 

Tree roots had entered a previous join made with the rubber and hose clamps system, so looking for a robust solution.

I have a "slab repair" PVC fitting that slides inside the earthenware pipe, and looking for an epoxy or polyurethane recommendation to seal and adhere the two pipes. It is a snug fit.

(in the photo, the earthenware pipe is at the bottom and runs under the concrete slab.)

Hi @Traveller,

Thank you for your question about sealing around a Deks 100mm EW To PVC Rubber Joiner Adaptor.

I'd suggest sealing around the outer edge of the adaptor with Sikaflex 11FC. You can also apply a bead inside the adaptor before tightening the pipe clamps to secure it in place.

While it is likely still possible for roots to break through over time, this will help keep the moisture inside the pipe, so the roots aren't attracted to it.

Let me know what you think.
