Weekend warriors

We are hoping to sell our home in 2-3 years. We have decided to tackle a job about every weekend so we can have it in ship shape for selling. This weekends project will be fixing the low spot in the basement. We have a home that was built in 1915. When it was first built it had a water well in the basement to hold runoff rain water, I am told. Our basement is partically finished. The laundry room and bathroom are finished. We now want to make the 'Rec room' finished. That is why we need to fill in the low area (where the well used to be). Last night I cleaned up and repainted the wall. Today we will mix the cement and level off the area. I hope we have enough time to do this. Our kids are invited to a birthday party for a nephew of ours, we don't know if we are supposed to be there or not. I don't know what time. Hopefully we will be able to get that done, since next week we hope to get the walls up. And hopefully electrical wire in for outlets too.
