Help! My Driveway is Sinking, Cracking, or Washing Out!

For small cracks (less than 1/4 inch), you can use concrete crack filler or asphalt patching compound. Clean the crack thoroughly, apply the filler according to the manufacturer's instructions, and smooth it out. This is a temporary fix to prevent water from entering and worsening the damage.

For larger areas of cracking or surface damage, you can apply a concrete resurfacing product. This involves cleaning the existing surface, applying a bonding agent, and then spreading a thin layer of new concrete. This can improve the appearance and extend the life of your driveway, but it doesn't address underlying soil issues.

This involves injecting a grout mixture under the sunken concrete slab to lift it back into place. It's a more effective solution than DIY repairs, but it's best left to professionals. It addresses the underlying soil compaction issues, but it may not be suitable for severely damaged driveways.

If your driveway is severely damaged, with large cracks, significant sinking, or extensive erosion, replacement is often the best option. This involves removing the old driveway, preparing the subgrade, and pouring new concrete or asphalt. It's the most expensive solution, but it provides a long-lasting, durable result. A professional is absolutely required.

If poor drainage is contributing to the problem, installing a French drain can help divert water away from the driveway. This involves digging a trench, laying perforated pipe, and covering it with gravel. This is often done in conjunction with other repairs to prevent future damage. Consider professional help for proper installation and drainage design.
