Over the course of this very snowy winter (we're in New Hampshire), we have noticed that the half of our driveway closest to the house is rising, to the point that there is now a significant (~4" tall) "hump" at the entrance to the garage. When we have a small snow melt, we now get water pooling in the garage because the driveway is higher than the garage floor. I am assuming this is due to frost heaves, but I have never had this problem before and I'm not sure what needs to be done. I'm guessing that, come spring, the driveway may drop down to it's original level but may also crack in the process- is that right? Is this damage that will require replacement of the driveway or can it be repaired? Just wondering what I'm looking at as far as repairs this coming summer... Thanks in advance!
i'd think you've got wtr UNDER the driveway in the form of wet base which's freezing & expanding,,, there's more frost under your d/w than your lawn 'cause you plow it OR its ice cover'd,,, when it thaws, ck for drainage alongside the d/w,,, that should resolve the issue if done correctly.
