I brought house last year but I have problem with rain water because in backyard concrete don't have water drainage and concrete is also not leveled so when it rains water is going to garage. You can see in below pictures water started go in the garage and that pictures are in the middle of swiping water. So please may I have some suggestions about my problem.
I would imagine you need to engage a plumber to install a strip drain @na. The concrete shouldn't be level, it should slope away from the house and to a drain.
