What material is used for waterproof and plugging?

Water leakage often occurs in construction projects. In the face of sudden water leakage accidents, urgent and effective measures must be taken to prevent leakage. The common method to deal with these water leakage accidents is plugging, that is, plugging the leaking place with materials that can solidify in a short time, so as to achieve the purpose of plugging. Due to the different specific circumstances of water leakage accidents in engineering construction, the materials used for plugging are also different. Common engineering water leakage accidents mainly include point water leakage, linear water leakage and surface water leakage, and the speed of water leakage is also different.

At present, the plugging materials on the market can be divided into two categories according to their properties: agent plugging materials and powder plugging materials. First of all, let's talk about agent plugging materials. At present, the commonly used agent plugging material is polyurethane plugging agent, which is mainly composed of single liquid polyurethane and a certain amount of additives. The principle of plugging with this product is to quickly solidify after interacting with water, so as to achieve the purpose of plugging. Powder plugging agent is not easy to penetrate into cracks, so it often has the problem of incomplete plugging, especially in the leaking area of cracks, while polyurethane plugging agent is liquid, which can penetrate into cracks to form a more thorough plugging effect.

Let's talk about powder plugging materials first. There are many powdered plugging materials in the market, which are also relatively conventional plugging materials. Common ones are blocking spirit, waterproof treasure, waterproof and blocking king. This kind of plugging material is mainly made of inorganic materials and other additives, and is mainly used for waterproof plugging in areas with surface leakage, such as building walls or roofs, floors and walls of indoor toilets and kitchens. Powder plugging materials generally require non-toxic and tasteless materials, which will not harm human health and have strong adhesion.

After selecting the plugging materials, the construction will begin. For example, the details should be paid attention to when using polyurethane plugging agent for waterproof and leak-proof construction:

1, pay attention to the ratio of polyurethane plugging agent and water, and also pay attention to the construction temperature, because these two details will directly affect the solidification time and effect of plugging materials, and it is best to have professional guidance or participation in this work.

2. Before construction, the construction area should be thoroughly cleaned, and large cracks or potholes should be plugged with plugging agent first.

3. Then brush it twice with the prepared water repellent.

The above is the water plugging material that the rabbit introduced to you. Different types of plugging materials have different specifications and models, and the prices are quite different. Friends should do their homework before buying plugging materials. Choosing different kinds of plugging materials according to demand is one of the most critical steps.
