water in post holes

I have dug 15 holes for my deck ( 42" deep) I am building. 5 of these holes are filling in with water (should have pored concrete before rain came) had inspector out after I pumped the water out but still had mud in bottom of the holes which i dug out however within a couple of hours I had about 1/2" of water in 2 of the holes. Is there any way of correcting this problem short of digging new holes? I read that you shouldn't use fill in the holes as this may cause settling. It's been 2 weeks now since I first dug the holes and am anxious to get poring.

branro,

Welcome fellow Minnesotan! I just got back from Little Falls awhile back!

My recommendation is to remove as much soupy mud as possible from the bottom of each post hole. Slight moisture or an inch or two of mud at the bottom is no problem. Just dump a little bit of dry cement into each hole or even a bag and mix it around. Any remaining water will help to hydrate the cement, solidifying the base. After the mixture has cured, you'll be ready for the main job of setting each post.

You may want to use at least 1 bag per hole and use p-gravel after you insert posts on concrete pad (after it has solidified) to fill it up to grade...eliminates alot of hassle unless you are considering filling the holes completely and using post anchors.

Hope this helps!
