hello

i would like to have some help with this word: lifting hole.
the hole paragraph is as follows:

The contractor shall seal all unsealed lifting holes,
unsealed step holes, and voids larger than approximately 1⁄2 in.
(1 cm) in thickness. All cracked or deteriorated material shall
be removed from the area to be patched and replaced with a
waterproof quick-setting mortar in accordance with manufacturer’s
specifications. The expanded gasket procedure (EGP)
method is also acceptable for plugging lift holes and similar
patching.

thanks
