I have a bulkhead entrance to my basement. The bulkhead walls are mostly fine, with the exception being near the top. The top 6 or 8 inches or so of the walls are constructed of what appear to be cement bricks (or something similar). The metal doors are attached to these bricks, and the bricks are somehow adhered to the walls below. The bricks are covered in some sort of mortar or cement, and I wouldn't even have realized they were distinct from the poured wall if some of the mortar/cement fill hadn't started to chip away.
What has resulted is a situation where, if you look at the bulkhead walls from the inside, you can see a horizontal crack ~6-8" below the top of the wall. When it rains, some water seeps through this crack and accumulates in the bulkhead. (ground level is approx 2 inches below the very top of what you see)
Here's a close-up of the top left corner.
Finally, a shot of the "bricks" on the right side of the stairs in a place where it's not leaking, just to show how they are attached to wall.
I am going to try putting some hydraulic cement along the crack on the inside. However, I am wondering what else you might suggest?
I was thinking of digging up a foot or so of the soil around the perimeter of the wall, and replacing it with gravel to help water quickly flow below the level of the crack. Would that help?
