The purpose is to waterproof cement cracks to prevent more water intrusion. http://www.mrhardware.com/ Repairing cracks in concrete is important to maintaining the structural integrity and beauty of the surface. Cracks and sags between pieces of concrete are due to settling of the earth below the surface. Sometimes due to poor compaction of the ground below, usually undermining is caused by water. Poor management of water allows it to flow below the slabs washing away earth leaving the concrete unsupported until it breaks and settles. My goal is to seal the cracks with a flexible material that will give and take with the concrete as it moves with the frost or other forces. Masonry between two slabs will only crack and prevent the slabs from moving back together if that is the way of nature. You cannot glue the two slabs together. Prepare the area by first removing all loose material in and around the crack. Very narrow cracks can be filled with a self-leveling caulk, most are polyurethane. Cracks over 1/8-inch will require prior filling because they can suck up all your caulk in a foot or so. I used to use sand but after a year or less the sand can settle out leaving the caulk unsupported. Now I prefer using spray foam because it is flexible, waterproof and sticks to everything. I foam the crack, minimal expanding is easier to control, trim the foam close to the surface and coat with the self leveling caulk. When using almost any caulk I cut the tip very small to give me more control of where and how the caulk is applied. Then as I work the job and get the small cracks filled I can cut the tube larger to make filling larger cracks quicker. Take your time when using self leveling caulks not to get it too thick on an area that is not level. If you let it puddle it may flow over the slab where you don’t want it. On steep driveways I’ve seen a puddle of caulk at the base of the approach. We like Sika caulk, as used in the video, but Quikrete’s self leveling polyurethane is a quality product also.
