Fix leaks under garage walls..?
I have an old concrete-section garage. Water pools outside at the base
in a couple of places and eventually works it's way between the walls
and the base to the inside.
I've had a stab at filling the gap with a bit of crude pointing to no
avail - it may delay it slightly but it still comes in.
Might 'trowel mastic' be the answer?
Any other bright ideas?
