Drilling into Cheaply Made Walls Made of Brick, Block and Stone

[kenmcc90]

Hi everyone,

I REALLY need some advice on drilling in my house. We live in an ex council house which has absolutely nightmareish walls.

Basically they are made up of concrete and big stones and rocks so when you drill into them, if you hit a stone you can't go any further or the drill veers off to the side which causes huge holes in the wall and means we are having a really difficult time even putting shelves up.

We've had several joiners, builders and other tradesmen come round who said they've never seen walls made up like this before and I've searched the internet but there isn't really any information on these types of walls.

Any help would be excellent, it takes up so much time even putting up a shelf which is so frustrating!

Thanks in advance.
