Hello, I have been reading for quite some time about products that you can use to resurface a garage floor. It seems mine was poured with a very low quality of concrete and had no relief cuts in it. Was thinking of trying to resurface it then do a few relief cuts after but i think that may be like trying to polish a turd :). Anyone have success doing this? If not is there any other temporary options? Tired of having to use a plank of wood under my floor jack and laying on rough uneven ground. This is not a long term house so i am not willing to redo the garage floor. I cant seem to upload pictures from my phone but the garage floor has large rocks in it (1/2"-3/4" round) and a few cracks where the rocks seem to be coming out of. The cracks are not splitting apart yet.

Our new house has an unnecessary sump pit that I would like to fill in. The pit was previously used to drain the basement stairwell that used to be exterior to the house. However, a three season room was added that encloses the basement stairs and therefore the drain and sump are no longer needed. I would like to fill it for two reasons, 1. The sump smells musty and is contributing to a musty smell in the basement that also permeates into the stairwell through the drain pipe when when the door is closed. 2. When buying the house, we discovered there was radon present and a mitigation system was installed. This unused sump seems to be a route for radon gas into the basement when the lid is off and into the three season room through the drain pipe when the lid is on. The lid fits somewhat tightly and is made of wood. Can I simply fill the hole and pipe with concrete? What type of concrete would be best? Do I need to use some sort of gravel or dirt to fill most of it and then concrete a thinner layer? The pit is 11inx11in and 18inches deep. The concrete goes down the full 18 inches and the bottom is dirt. The drain pipe is about 2inch diameter and a run of 24 inches. The basement is dry. There is no sump pump.
