The basement of the villa is moisture-proof, and the Norwegian electrical penetration moisture-proof technology has been verified to be effective by the official underground works

After 34 years of practical application worldwide, it has been proven that the "electric osmosis pulse technology" invented by Tretton in Norway is one of the most advanced solutions for dealing with leakage moisture in concrete structures internationally.

The main application areas of electric infiltration and moisture protection are: concrete lining tunnel engineering, underground hidden engineering (including civil air defense basement, residential basement, underground shopping mall, underground parking lot, subway, highway tunnel, pipe corridor passage, underground bank vault, power supply cable tunnel, tobacco company, hospital, school, bookstore, grain depot, army, museum and other underground facilities), dams and underground plants in water conservancy and hydropower projects, marine infrastructure engineering, etc.
