The video talks about why galvanizing steel is important to protect steel from corrosion. Steel is prone to corrosion when it comes in contact with moisture and air. This can compromise the strength and lifespan of the steel, and also the foundation repair system. There are two main methods to protect steel from corrosion: powder coating and hot dip galvanizing.

Powder coating is a cheap and readily available solution, but it is not very durable. The coating is porous and can be easily damaged, allowing moisture to reach the underlying steel. Additionally, the coating thickness is variable, which means that some areas of the steel may be left unprotected.

Hot dip galvanizing is a much more durable solution. It involves immersing the steel in a kettle of molten zinc, which creates a metallurgical bond between the zinc and the steel. This coating is much tougher and more uniform than powder coating, and it also provides cathodic protection to the steel. This means that even if the steel is scratched, the zinc will sacrifice itself to protect the steel from corrosion.

In conclusion, hot dip galvanizing is the best way to protect steel from corrosion. It is more durable and effective than powder coating, and it provides superior protection for your foundation.

I hope this is helpful!
