How do I minimize frost heave?
I live in Alberta and over the past few years I have had minor frost heaving in the front of my house near my raised steps and driveway. Each year it seems to get a little worse, and this year was BAD. My driveway raised to the point where my truck was on an angle to the side when parked, and one side of my steps raised enough to pop the ledgestone (polyeurethane) off the wall. I can put the ledgestone back when the steps settle but the damage to the driveway really concerns me.
My question is this: I have been hesitant to have my driveway replaced because of the fear that it might happen to my new driveway and waste all that money, but since it seems to get worse each year, I am wondering if it isn't getting worse BECAUSE of the damage. This year I could actually stick my arm under the driveway from my garage. I have a feeling that because of the existing damage, the brutal cold air is given free access to all ground moisture and causing the heaving to worsen, so if I have it replaced is it logical that the new driveway could block access to the ground moisture?
Thank you for your replies.
