Drilling into foundation wall


We've had a rash of break-ins where burglars have broken into homes (even with alarm systems) by cutting the phone lines thus disabling the reporting capabilities of the alarm system. I've been told the best thing to do is bury the phone line below grade, drill through the foundation wall and run a conduit into the basement so the lines can't be cut.

Is it wise to go punching holes in a perfectly good foundation?

If so, I heard a hammer drill is the best bet. Figuring I'd have to get me a might long bit to go through a foundation wall!

After running my conduit, what's the best method of sealing it back up so as to prevent against leaks?

Drilling into foundation wall


yes it can be done with the tools you mentioned. Walls are not that thick. 8-12" at most. silicone caulking or electrical duct seal will seal the pipe penetrations

You might want to consider drilling the hole at just a slight downward slope angle from the inside toward the outdide. If there have been any past water intrusion problems then you might think about a product called "fast plug" or other cement type fillers if you break/drill an opening bigger than what you intended.
Good luck

If you decide to do this work and you have a harbor freight tool store near you, you might want to pick up their SDS hammer drill. It is by far the cheapest option for this type of tool (around $70) and it works very well for drilling concrete. The build quality is questionable but if you are not using it every day then this may not matter.

I bought one and have been impressed. It is a big step up vs non-SDS tools.

' sds ' refers to the type of chuck holding the bit's shank,,, h/o drills have a jacobs chuck - pro tools ( hammer drills, etc ) use sds, tapered, improved sds, or spline bits for this work,,, we never buy harbor frt/ north hyd as the power tools suck,,, nothing's more frustrating than having a tool **** the bed,,, cheap tools're the most expensive tools a pro can own,,, the best tools continue to work & don't have legs milwaukee, bosch, & skil - that's our list.

rent the drill & bit if you decide to do the work - here its $ 35 for 1/2 day - you'll need it for 20min at the most

It may be easier to get a "cellular back-up" for your alarm system. Ask your installer or alarm co. Your alarm system can tell if the phone line is cut, but may not be able to dial out. If you loose dial tone, the cell will place the call. Plus, it will have some life as well if the power goes out. This may be a safer and better option.

If you go the conduit route then be sure to use metal conduit.Plastic is still easy to cut with a hack saw or break with a hammer.
