I am converting my garage into two rooms and am wondering how the best way to anchor the new wall to the existing concrete slab. The only thing I can think of is to drill holes and cement in new anchor bolts. If so, what's the best way to drill the holes and how deep? The usual is 6" (minimum)! There is also a risk of hitting the water line which runs through the slab, right under the garage. That would be an expensinve mistake! HELP!!!

The easiest way to anchor a 2x4 wall to a slab is to use powder actuated fasteners ( There are several brands depending where you live but they're all very similar.

They shoot a pin (usually 2 1/2" long for a 2x4 wall) through the 2x4 into the concrete (usually about one pin per bay along the wall). The pin should only penetrate about 1/3 of the slab thickness to prevent the slab from cracking. They also recommend testing the concrete with a fastener and a hammer to see if the concrete is either too hard or too crumbly to use the powder actuated method.

If you can't use this method I would just drill a 1" deep hole with a masonry bit and use regular expanding concrete anchor. Over the span their strength will be enough.

Good Luck.
