We have been experiencing water in our basement and garage.
Project Location: Ashford, CT
Good morning, We are looking to have our basement sealed and renovated, hoping to put in an office and home gym. Our basement is roughly 400/450 sq ft. We live in an older house, and will need the basement to be waterproofed/sealed and we would like to put in an epoxy floor to warm up the space a little bit. We are interested in getting two separate quotes: 1) what the cost would be to just waterproof/seal the basement and have an epoxy floor put down/in. 2)In addition to sealing the basement and putting in an epoxy floor, what the cost would be to have framing and drywall put in to section off part of the basement and to have electricity run to have outlets in the new walls. We are really want to make this a livable and usable space for everyday use. We look forward to hearing back from and you! Thank you so much! Shelby and Nick Masse

I have a concrete slab that my standby generator sits upon outside. It's about 2'x5 feet, or so. The land isn't level, and on one side of the slab the earth being washed out from under it. I'm afraid in time the slab is going to crack because it's not being supported correctly. Would PolyLEVEL be a solution to this problem? What might the cost be for such a small job? Thank you.
