Hi Team,
I would like to tackle fixing this ugly hole in the brick wall on the side of my house. Not sure why did the previous owner make it but it is quite convenient entrance for possums and other rodents so it has to be sealed.
The bricks are (roughly) 23x11x8cm, which seems to be a standard size.
I am guessing I will need to cut the existing broken bricks first and replace? I have an angle grinder, would that be a good tool for that?
What goes on the bottom? Can I just put a layer of mortar on the bottom? What mortar would be suitable for a job like this? What size bag?
The other thing I am unsure about is the barrier that is supposed to stop rising damp. There are a bits of it left but it has deteriorated. How do I replace that? Thanks for your help!
