Below grade window fill
I purchased a home and with all the recent rain I removed the basement paneling to find a leak. I discovered the home at one time had no garage. T some time the window well (see attachment) had been covered with wood and filled with dirt on the outside afterwards a garage was built on that side of the home rendering the window closed forever.
Now water has rotted the wood and is leaking into the basement. Can I fill the void with concrete? Will it create a seal or will it still leak? How do you fill a vertical void? What type of cement do I use?
Any advice is greatly appreciated. I need an expert opinion.
