Out of all the construction materials, concrete is one of the most commonly used types due to its durability and versatility.
However, this durability does not last forever as it is still exposed to various elements which erode the concrete’s bond. Over time rain, UV rays, wind, and freeze-thaw damage weaken the concrete’s structure.
To combat this inevitable breakdown, bonding agents are used in maintaining the integrity of the concrete. In this guide, we will highlight a few of the best bonding agents for concrete, as well as some pointers to keep in mind when choosing an option.
Without further ado, let us begin!
