I have a garage built from brick. The neighbour has built a patio that butts up to my garage wall. See my attempted ASCII drawing below.
When it rains heavilly the water runs off his patio, soaks through the wall of my garage and floods it to about 1/4" deep! (Yes, I have checked the roof etc for leaks)
Whilst I realise the neighbour should have left a drainage channel, the chances of him digging up his patio and fitting one is virtually nil.
I can buy liquid especially for waterproofing brickwork. Is it any good? If I were to apply it liberally to the bottom of the wall on the outside where the water is soaking through...would it work?
Alternatively, I was thinking of applying some sort of flashing/weather strip along the area where the patio meets the garage. Would that work?
I'm after the lowest cost/least effort solution possible.
