Concrete – How to patch these sections of concrete driveway meeting the house

concretedriveway

Where my driveway meets my house there were two sections of loose concrete that were deteriorating and making a mess. I removed the loose concrete and discovered that those sections were placed on top of other concrete that I am guessing is the footer of those outside walls of the house. These missing sections go down 2 1/2 – 3 inches. How would I go about repairing these sections in a manner that would last. Do I need to tie the new concrete into the existing footer concrete that is there? What about the joints between the old and new concrete? I am a noob with any type of concrete work so any help or advice on how to fix this is appreciated.

You could simply add new concrete to it. There are a few things you need to do:

  1. Clean all dirt and dust from the patch hole.
  2. Use a bonding agent to help new and old concrete bond together otherwise the new patch just "floats" (you brush this on the old concrete but can also add it to the cement mix as per the product directions to help prevent cracking)
  3. Mix and pour the cement.
  4. Once cured, Seal the edges of the patch
