Ok currently my house's bathroom has a big hole on the wall , not really big the circumference is just like the tennis ball , and also in between the bathroom's floor and wall , that's the vertices of the wall(since wall is square lol , so use math vertices) , there's small crack and holes also.My house is semi detached so i just get to the other side of my bathroom wall and lucky the crack is not on the whole brick as outside can't see it.So how am i get to deal with it??Thanks for reading my problem.And I prefer DIY so hope get any enlightment from expert

Probably due to water causing the hole to appear , and besides that new hole keep produce
