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