I thought walking on a treadmill twice for 10 minutes was exercise, until I tried to fill gaps in the foundation wall, during a warm spell.
There is something I can't understand about these cracks, because I kept pouring old powdered cement into what seemed to be a bottomless pit! Maybe it will be worse, if water seeps in, and now expands, since there's less space, meaning the walls could be under more stress?
I'm only going to use dolomite sand around the good pavement anyway, for traction.
But how could there be so much space in a passageway between two semi-attached houses?
