Duct capping

[Vijay]

Openreach guy came round today and was pretty helpful. He wasn't too happy that I want to bring the ducting under the B&B floor and into the under stair cupboard. His issue is any gas or water coming through the duct into the house. He said they normally use a resin on an outside pipe but we have radon gas and I would therefor need a duct cap that can seal any gases. Has anyone come across this issue?

 

Cheers

Wonder if you would get away with Wiska Gel? A squirt of foam first then:

Yep that looks perfect. I've messaged them for a quote (reckon I should be worried when a website doesn't show prices!! lol)

 

That gel only mentions water though. I got the impression it was the radon he was concerned about..................

One Gel is gas tight? Dunno about radon gas though:
