can anyone give me any advice i have removed a tiolet and am left with a hole directly to the outside where the waste pipe was located i thought of using concrete but was unsure how to go about this due to the thickness i have to fill :?
boo1981,
Internally, buy one aerated concrete block, roughly cut it to fit the hole and fix it in place using mortar.
Externally use same mortar and cut bricks to fit hole.
