We have started to cut the basement windows now. This saw is a wet cut saw, meaning there is water flowing to cool and lubricate the blade. This presents the problem of water everywhere inside the basement.
The question is, has anyone had any experience with these types of saws, and what do you do in the interior to prevent water damage?
I know this is not what you want to hear, but I suggest hiring a professional. Concrete saws are hard to use. There probably is re-bar in the concrete as well. Without experience and training, you could ruin the wall and/or kill someone. As you realized, the “flood control” from the cooling water is difficult. If this is not done right, you can cause thousands of dollars in damage.
Also, I hope you had a structural engineer study at the walls you’re cutting. A larger opening could compromise the structural integrity of the wall causing the house to sag or worse.
Not a contractor or engineer but I know a few people who have created big problems for themselves trying to do it themselves. I’m pretty sure it’s code to add a lintel over the windows you cut to carry the load, looks to me to be more than a DIY project. I think Ex_Chemist is right about getting a pro for this.
Contractor, here. My experience would tell me that it’s a specialty, and the tools are quite expensive, and I don’t do enough of it to depreciate the saw and get my $ back, and I’d be better off hiring a subcontractor who is experienced and properly insured, and let him potentially eff up his saw, as well as manage the mess.
I’d give him dimensions, mark the wall, and work out temporary supports of the dwelling, just so we aren’t left with part of house hanging like the Sword of Damocles above our pointed little heads.
