My dear husband has a double with some outside steps to a basement door.
He wants to fill this in and eliminate both the access to and the door.
I'm sure he wants to seal where the door was permanently. He was
thinking about filling the space with cinder block.
I am concerned about water leaking forever into the basement. There's
leakage down the steps and under the door as it is.
What would be the best way to seal where the door was and fill the hole
where the steps presently are?
