This kind of concrete is also known as self-repairing concrete. Because concrete has a poor tensile strength compared to other building materials , it often develops cracks in the surface. These cracks reduce the durability of the concrete because they facilitate the flow of liquids and gases that may contain harmful compounds.
Dowel bar retrofit (DBR) is a process that re-establishes load transfer capability on joints and cracks by installing epoxy-coated, round steel dowels into existing concrete pavement across transverse joints and/or cracks. Slots are cut using diamond-tipped saw blades; the existing concrete is removed and the dowels are placed in the slots ...
Example of flat piece of concrete having dislodged with corroded rebar underneath, Welland River bridge across Queen Elizabeth Way in Niagara Falls, Ontario.

D codes to fix both problems by cutting a set of stairs into the middle of the wall. Only had to cut 2 of the old big blocks in half as the pavers fit perfectly with the spacing of the blocks.
In poured concrete foundations, cracks and pipe penetrations are the most common entry points for seepage. These openings can be sealed from the interior. Epoxies , which are strong adhesives, or urethanes can be pressure injected into the openings, thus penetrating the foundation through to the exterior and cutting off the path of the seepage.
Some of the most important types of crack are as follows: [1] [4] Crocodile cracking, also known as alligator cracking and fatigue cracking; Block cracking (caused by shrinkage of asphalt) Longitudinal cracking—wheel path; Longitudinal cracking—non-wheel path; Transverse cracking; Reflection cracking at joints
