Flooding into garage

Hey guys,

So now that the frost has set in, I'm getting water collecting at the base of my garage (slab construction, top of slab not very high off grade, maybe 2-3 inches).

The backyard is sloped towards the garage (I didn't build the garage, previous owner should have known better and built slab higher).

In the spring/summer/fall any heavy rains are handled ok, the water soaks into the ground and doesn't collect at the base.

But it is winter, we have had a good cold snap and there is plenty of frost in the ground. This week we had a warm spell with some heavy rain. The water has no where to go now, and just collects at the base of the garage, and then leaks in under the sill.

I'm thinking a french drain won't really help here, as the ground will freeze regardless and the water still has no where to go.

Suggestions?

Thanks

Tim

 

can you construct a berm before the garage to divert the water around and past?
