I want to cut into a block foundation with brick veneer for a new window. The basement is a walk out. I will support the brick with a new lintl. How can I support the block foundation?? The window will be +-36" wide.

Newbie here would like to add to the previous posters question. I want to put an egress window in a block foundation where there is a already a standard shallow basement window. How do I go about cutting out the block foundation for the window, which will be about 30*48in.? Also, how do I rough in a window frame where the block will be thin or open on the sides?

Thanks,

You will also need to install a lintel in the block opening. The lintels used in a block wall are generally made of steel reinforced concrete designed to match the block wall. They must rest on at least 8" of the block wall on both sides of the opening and the area of wall supporting the lintel should be filled with concrete block fill or grout before installing the lintel.

Using a diamond blade on a "Quickie" saw (or pipe saw) is one way to cut the opening. To repair the sides of the opening you should "tooth" out (remove) the hollow bocks that have been cut and replace them with square end blocks cut to fit (with the cut side facing the existing block) to achieve the smooth solid opening you need.
