jfb Posted September 13, 2022 Share Posted September 13, 2022 I have some BT duct 54mm popping up out of the ground that I want to run two data cable from one building to another (not asking BT to do it at the moment). How best to have 2 cables coming up out of it and to seal it properly? Cant seem to see anything obvious that is designed for it. Link to comment Share on other sites More sharing options...
JohnMo Posted September 13, 2022 Share Posted September 13, 2022 I used spray foam, then a coat of CT1 adhesive/sealer Link to comment Share on other sites More sharing options...

TonyT Posted September 13, 2022 Share Posted September 13, 2022 Scrunch up newspaper, push down duct, mix up weak mortar mix and fill up. or expanding foam and weak mortar mix. Link to comment Share on other sites More sharing options...
Temp Posted September 13, 2022 Share Posted September 13, 2022 I filled about 6" with expanding foam, but my duct was for power and the end was buried under a patio. Link to comment Share on other sites More sharing options...
