DriBond™ is specially designed for the overlay of thin pavers (1" or 30mm) or natural stone over existing concrete. With DriBond™, there is no need to remove the existing concrete substrate, which is a costly and time-consuming process. DriBond™ is a polymer modified bonding agent that installs like sand and sets like cement.

A cement bond log (CBL) measures the amplitude or attenuation of waves propagating axially along with a casing. The attenuation of the wave depends upon the materials on both sides of the casing: mud inside the casing and cement in the annular space. The effect is more pronounced on the casing-cement interface than on the mud …

Fixing concrete takes a number of materials because it does not readily adhere to other concrete. The mixture and formation relies on a chemical reaction that stops once dried. If you need to patch a concrete surface or pour new concrete on top of old concrete, you must invest in a strong bonding agent and a concrete patching mix.
