Have you observed specific problems? If you walk outside today, I will say you have it. Especially in the cold climate of the United States. We all know how the free-thaw cycle affects concrete, and when a person puts down the repair material, it doesn't last a winter. Therefore, in general, once the weather gets warmer, maintenance personnel will apply more of the same material.
Wouldn't it be nice if people could put down the material and keep it for more than a year? The external stairs in the shopping center. After years of free thaw cycles, salt is applied to the stairs in winter and the concrete gradually disappears. Now is one of the two options for the operations manager. One option is to hire a contractor to enter and use the ready-mixed concrete or Portland cement repair material to repair the stairwell. The second option is for internal employees to use polymer modified materials for repair.
Now we will evaluate two options. It is great when the contractor can offer and repair at a lower cost than replacing the entire staircase. Your problem arises when winter comes, because the adhesion between concrete and concrete is not strong enough, and your repair will not last for more than a few years when your freeze-thaw cycle occurs and your chloride sinks into the surface. There are ways to protect concrete from chloride attack and how to strengthen adhesion to the surface, but some contractors are concerned about profits and will make this situation even shorter.
When using non-cement polymer materials such as Enecon Duraquartz, one does not have to worry about bond strength or chlorination resistance. The material retains chloride during the winter and has such a strong bond strength that it cannot break without tearing the existing concrete during the process. How about the curb of the parking lot? The strength of this material is almost four times that of conventional concrete, which means that Duraquartz does not fail when repairing with traditional repair materials fails.
