Garage Flooding

In the spring, my garage has been flooding when the snow melts. My garage is the lowest point in the back alley and my driveway is almost level with the alley. I have been moving all the snow myself from the back of the garage to the front, which has not been an easy task. I am not sure if there is a fix without building a new garage. Could flood barriers help? Also, any suggestions as to what kind of a portable sump pump to buy? I broke the one from the Senior Centre I borrowed last year (it was quite old but did a good job while it lasted).

Any suggestions or possible help to my problem would be greatly appreciated.

Thank you.

Hi Monika. There are a few solutions to your problem. Last year we raised a garage which had a similar problem, added a perimeter grade beam, removed the existing concrete floor, added new fill and reinforcements, poured a new concrete floor, which raised the garage about 16 inches, and now it does not have a problem.

A sump pump and drain would solve the flooding inside but does not address the real issue which is the grade.

If the garage slab is otherwise in good shape you could try mud-jacking. My next door neighbor did this to correct the same problem and it worked like a charm.

A friend raised his garage by attaching 2 x 8" lumber along 2 sides and using jacks to lift the garage, then not sure if he removed the old broken up slab before adding some road crush and pouring a new slab.
