Hello,
my wife would like to have our basement window removed and the resulting opening closed. The window is completely below street level.
Our basement was poured with waterproof concrete, coated with bitumen, then the perimeter insulation was applied, and finally the dimpled membrane.
My questions are:
1. What is the best way to close the opening?
2. Should I use formwork and concrete? If so, all at once? What is the best way to seal the top edge, considering concrete shrinkage?
3. Or should I use masonry?
Thank you in advance.

If only I could find those strange brackets mentioned and give the bricks support in the reveal Either bend flat anchors at a 90-degree angle and fix them into the reveal with wall plugs, or drill holes and secure anchor bolts with quick-setting mortar (from a cartridge). The ends are laid into the new joints and mortared in.
Efflorescence only occurs with moisture, or when it dries out. And if you really want to reinvent the wheel, use shuttering blocks. But it’s just more effort and doesn’t bring any benefit at all.
