I'd like to drill into poured concrete basement walls to set some modest anchors to secure the tops of some freestanding shelving units against tipping on top of small curious nephews and nieces who might decide to climb on em.
Anything I should know/avoid? I guess my primary concern would be opening a water infiltration path, but I'd have to think there are tons of anchors drilled in other walls behind the finished portion of the basement?
I assume a hammer drill is the tool of choice for this task?
TIA for any shared experience!
