Bricks, Masonry, Asphalt and Concrete - Sealing a veranda

Hi,
We have a veranda off the back of the house which has a concrete deck. This deck is also the roof of a garage. Water is seeping into the garage. There are hairline cracks in the veranda deck. Any suggestions on how to seal this to keep the water from seeping through. Also, I found a product called AboCrete from Abatron, Inc. that seems to fit this application. Anyone heard or used this?

Thanks.
Dave.

I have never used or heard of AboCrete until your post. But in the past I have used epoxy to patch concrete and can tell you that the waterproof types (seems like AboCrete meets that category) are highly effective and some are stronger than the concrete itself. Along the same lines underwater grades of epoxy are used to fix full swimming pools and bridge pilings. I have not read all of the data, but one draw back to epoxy is that non UV stabilized types tend to yellow over time when exposed to the suns rays.
