Step One: Remove Damaged Pavers

Step Two: Examine the Base

Replacing the Mortar Once you have removed the sunken pavers, you should now examine the base to determine what the cause of the sinking pavers is. If you think that there is a lot of damage to the base then you will need to remove it, with the use of a sledgehammer.

Then replace the base with new concrete, but be sure to fix the underlying problem first. If you have problems in finding the cause of the problem, it is always a good idea to use reinforcing wire mesh.

If you are not going to replace the concrete slab, then use a sand mix to level the base to rest of the pavement. Allow it to cure for a few days before replacing the pavers. Be sure to clean the area before placing in the sand mix.

Step Three: Replacing the Pavers

  • Clean up the pavers by removing all the old mortar, with the use of the chisel and sledgehammer.
  • Now lay a ½ inch layer of mortar.
  • Butter the head joints of the pavers and start to lay from one corner of the damaged area.
  • Flatten out the tops of the joints so as to prevent water penetration.
  • When the mortar is dry, sweep away any loose debris from the area.
