chasing concrete walls

[pennywise]

If the internal Walls are really thin, I try and offset back to back sockets so you get at lest half a boxes width supported by wall even if you do go right the way through on the bit that is directly behind the other socket.

And people think electrical is easy , the amount of engineering thats some times requred is unbeliveable

Dot and dabs ok when done with a decent amount of dabs. Its when you get a wall with 8x4 sheets and only 6 dabs that its becomes rubbish IMO.

Worked on a house once a thought the wall was a standerd stud wall as when tapping the board the wholes board flexed, cant believe the board stayed stuck to the wall as hardly any adhesive had been used.
