My condo is made out of concrete. I like to put a wooden board up (~25mm thick, 600mm in width, and 1800mm in height) on my concrete wall so I can nail up the wall and load it on with tools (drivers, drills, wrenches etc.)
- How to locate if there are electrical wire running inside the concrete? I have no drawing of the condo. I have seen construction worker having a handheld device that beeps when they survey a concrete wall. Is that what it is and what is it called?
- There are so many type of screws I found online that drill into concrete. For example, this. The description wasn't very helpful and I wonder if someone can help tell me which screw I should use to drill through a wooden board and into a concrete wall
