Waterproofing and moisture-proof has always been a problem in the maintenance and management of underground engineering, which has caused serious harm and adverse impact on the operation of mechanical and electrical equipment, the storage of equipment and materials, and the work and life of personnel.
For a long time, the treatment of leakage has been the use of high-pressure chemical grouting and other passive methods, waterproof effect and engineering remediation service life is limited by factors such as materials and construction, it is difficult to cure, easy to recur, and high cost.
The failure of basement moisture protection is mainly because traditional moisture protection cannot solve the capillary phenomenon of the building body. Concrete has many pores under the microscope, and in concrete and masonry structures, water molecules can penetrate into the interior of the structure in a variety of ways.
Among them, the simplest way is that water uses its own gravity or lateral pressure to infiltrate into the structure through pores and various cracks; at the same time, water molecules can also penetrate into the interior of the structure through the pores in the structure, and the smaller the diameter of the pores, the more obvious the water absorption activity.
The electric osmosis technology moisture-proof technology invented by Tretton in Norway is the use of low-voltage positive and negative pulse currents, so that the positive polarity of the water molecules in the structure (such as pores, cracks), the energy of movement is greater than the energy of the water's self-gravity and the siphon force of the pores in the structure, and can withstand the action of high-pressure water.
The principle of Tretton electric penetration moisture protection technology in Norway
As long as the positive and negative pulse current is continuously applied, the water in the structure will always move towards the negative side (the outside side of the structure), forming a closed anti-seepage barrier to prevent water or moisture from penetrating into the inside of the structure.
