Sometime over the history of my 60 year old house, it was built underneath with a garage directly under the patio. I don’t think it should be like this but it can’t be changed now.
Up until this weekend, the patio floor was covered with very old, severely deteriorated stick on vinyl tiles, which were stuck onto some kind of board, which was nailed to the original floor boards. I’ve pulled up the tiles and board they were stuck to and now the floor boards are exposed.
As the patio is over the garage it needs to be waterproof and a lot of the floor boards appear to have water damage.
Can anyone advise me on what to do to stop rain getting into the garage from the patio? Would really appreciate any help I can get, thanks.
