how to knock off slab remainder?
The slab for my garage looks like it wasn't finished right. Take a
look: http://yfrog.com/58things1j http://yfrog.com/58things2j You can see a lip that extends beyond the face of the slab. I'm about to cut off the rotten siding and replace it. But it's clear that one reason it rotted is because water would hit this lip and bounce back onto the siding. What's the best way to remove this lip without damaging the face? You can see in the 2nd image that it looks like the face has been knocked away past where it should have been. I want to avoid doing that myself. I was thinking a cold chisel and a sledge, but I've never done anything like this. thx |

I want to avoid doing that myself. I was thinking a cold chisel and a sledge, but I've never done anything like this. You could score it first with a saw. Even a standard circular saw would do it using a diamond masonry blade or multiple cheap masonry abrasive blades. It won't be fast. Then use the sledge How high up does the concrete go? A better bet would be to leave more space between the ledge/ground and the siding. 6 inches would make a huge differemce. You could also coat the bottoms of the boards with a penetrating epoxy like "git-rot" to prevent moisture penetration, or at least a good preservative. I suspect that cutting the bottoms with a bevel, so they drip from the outside edge would help keep them from holding and wicking water also. |

I was thinking a cold chisel and a sledge, but I've never done anything like this. thx A sledge is way too big and tiring to use to hit a chisel, you need about a 2 pound club hammer for the job. Even that will not do a good job as the concrete looks old, hard and brittle, and could cause it to break in the wrong area. If you are determined to remove it, rent a chain saw with a masonry blade adapter. After you remove the siding you will have a little more room to use it to cut back the concrete or at least make a cut deep enough that you can snap off the excess cleanly. |

I was thinking a cold chisel and a sledge, but I've never done anything like this. That's a lot of work for little benefit. Unless you find the concrete aesthetically objectionable, just deal with the problem when you do the residing. First do your tearoff, verify that the sill plate is in good condition - if not replace with treated wood, caulk/seal sill to concrete, install aluminum kickout flashing on the studs, {option: install PVC water table trim over the kick out flashing}*, install pressure treated T-1-11.

They should have formed up and poured a foundation wall, or laid one up out of block. Wood walls should never sit on a slab outdoors. Hard to tell from the pics- they may be a short one there, but there should be 6-8 inches of concrete showing above the dirt outside, and above the slab inside. Lack of this is likely what destroyed the bottom of the current siding, from the splashback, and seepage from inside under the sill plate. Short of jacking up the garage and adding a wall, or cutting in and adding one in sections, the best work-around at this point is plastic or metal flashing below the cut-off siding (whatever can me made to look 'good enough') and lots of paths for water to run out and not get trapped under sill plate. That garage will always have dampness problems. -- aem sends... |

Keep it high enuf to avoid contact with standing water, etc, the ground does not look to be sloped away from the slab very much. Builing up the walls should be a much easier and faster way then trying to cut the lip back. |

A saw/blade combination made specifically for concrete will work too, but this will produce a messy cloud of dust. Just remove what is absolutely necessary to improve drainage. |
