Almost all buildings get damaged at some point, whether from a weather disaster or the building is really old, so it's highly recommended to do a building health check for building maintenance. It is suggested that before you start the building repairs, you select the right equipment and a professional concreter since most used material for repairs is the concrete. When selecting a concreter, make sure that he is very familiar with the process, is licensed and has insurance.
It is incredible how many types of concrete are out there. You could choose from regular concrete or also called plain concrete, high – strength concrete, stamped concrete, high performance concrete, self- consolidating concrete, pervious concrete, polymer concrete and many more types that could be used.
Even though concrete is available in many different varieties, it is a much more complicated material than it may appear. When concrete is placed outdoors, on a garage floor, patio or a sidewalk, concrete spalling may occur. There are several primary ways that concrete can get damaged in the winter time due to the cold weather:
1) Sub florescence and De – Icers
2) Melting freezing water
3) Salt corroding rebar metal
How these three primary ways cause concrete damage; repeatedly, de – icer is used on concrete in the winter months. Once the snow melts down, the water seeps into the concrete and evaporates which leaves the salt to go underneath the concrete. This pushes off the outer surface of the concrete and causes damage.
Adding de-icer on frozen concrete surfaces will mix with the water and cause temperature change which causes it to freeze.
When rebar metal exists in the concrete, salt and other deicing chemicals cause rust and corrode. When this happens, the corrosion will put pressure on the concrete that can cause the concrete to crack. As the concrete cracks, it will be more susceptible to de-icer and salt which causes the concrete to break even faster.
An effective way to prevent concrete from damage, it's suggested to treat it with a saline based concrete sealer before the damage occurs. The concrete treat can be used for indoor and outdoor use.
