Common mistakes and solutions of damp proof and dehumidification in villa basement

1. Do the SBS coil in the basement wall, brick wall, on the outside of the coil as the basement is a pressure water, in the construction of internal Angle corner of SBS coil is not in place, easy to the drum shell, the basement to resist the pressure water lead to leakage, villa basement moisture failure, the reasons for this problem is waterproof construction group of basement waterproof concept is not clear, Treat pressurized water as roof water. Therefore, SBS and other waterproof rolling materials can not be used as damp proof construction materials for villa basement.

2. Inside the villa in the basement for JS waterproof coating, JS waterproof coating belongs to the cement based waterproof coating, although it is acrylic emulsion and filling material waterproof membrane formation, but there is a large number of capillary channel, the coating can be waterproof but do not prevent moisture, large amounts of water vapor can also enter within the basement, cannot effectively the humidity in the basement. JS waterproof coating thickness is less than 2mm, can not eliminate the temperature difference between indoor air and wall, can not effectively prevent condensation phenomenon. Therefore: villa basement moistureproof with JS waterproof coating is also wrong...

3. Inside the villa in the basement of polyurethane waterproof coating, polyurethane waterproof coating sealing is good, can waterproof 15 meters water under pressure, but pu have a fatal disadvantage is that the construction is difficult, general workers are difficult to grasp the construction quality, almost 90% of polyurethane waterproof coating and combined with the weak at the grassroots level in the basement water pressure to the drum, This is due to the two-component polyurethane solidification time is too fast, too late to scratch the coating, and the base bond is not firm, if you want to bond firmly with the base, you must dilute with xylene and do a good job of the bottom coating, but xylene smell, we all know that dimethyl stupid is banned products, it will induce cancer... It is difficult to volatilize in the basement, which is irritating and unbearable for workers during construction. Finish polyurethane waterproof coating, but also do cement mortar protection layer outside. This layer of ordinary cement mortar contains a lot of water vapor.

Install TQ-EPT electro-osmotic anti-permeability dehumidification system + air dehumidifier. The tQ-EPT electro-osmotic anti-permeability dehumidification system simply generates a specific frequency pulse between the positive pole on the indoor wall and floor and the negative pole in the outdoor soil through the control part of the indoor host, and directs the water molecules to the outdoor in a directional arrangement.

Based on the company to the basement moisture source and formation of the principle of knowledge and years of experience in dehumidification, advises clients basement installation TQ - EPT electroosmosis pulse permeability dehumidification system, at the same time to install air dehumidification equipment (portable dehumidifier or central air dehumidification system), the former keep dry and structure, the latter to adjust air relative humidity, two kinds of equipment system perfect combination, Solve damp and mold problems in basement completely.
