I have 2 15mm heating pipes going through a block work wall to feed another rad the otherside.
The guy who done the job drilled 22mm holes and passed the 15mm pipes through some 22mm pipe like a protection sleeve.
I now want to fill the hole to make it tidy, what fillers can be used that can withstand the heat of the heating pipes passing through the wall.
Thanks
