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?

Drill some small holes in the floor and let the water drain away.
Out of sight - out of mind.
