Despite your best efforts to remove large rocks and trees from around your driveway, they can still find a way back. They can cause a lot of damage to your driveway paving, requiring you to hire a contractor to do the work all over again. There are some preventive measures and some treatment measures you can take to keep your driveway smooth.
Tree Growth and Roots
Canadian trees grow like the wilderness around them. They are fast, tall, broad and set in roots that can damage any kind of concrete and asphalt your contractor puts down. The roots are the worst part because they grow at the surface level where they can crack the pavement in your driveway and loosen huge chunks of asphalt. To prevent this problem:
If you are installing a new driveway and there are full-grown and growing trees close by, consider shifting your entire driveway a meter in the opposite direction of these trees. Some people try to construct a concrete and asphalt driveway around the base of these trees, only to find that it was a bad idea and the driveway needs repaired a few years later.
"Glacial" Movements of Rock
During the typical winter in Canada, lots of rock underground shifts and moves upward toward the surface. Small pebbles and stones have little effect on a well-established driveway, but small boulders can crack your asphalt like a stick. Falling rock, like those that trickle down the Canadian Rockies, can make quite a mess of driveways closest to the feet of the mountains. To prevent this problem:
In the spring or fall, consider leveling your yard to a smooth flat surface. Roll the land drum away from the driveway because this will encourage unseen rocks to push away from it. Your yard will have a more even appearance, the driveway will be spared the annual underground rock movements caused by the freezing and thawing of the earth.
