Speaking of bentonite waterproof blanket, I believe this product is very common in our current life, because of its own advantages, it is still very popular in the market. In order to let more people understand the bentonite waterproof blanket, the next editor will tell you about the function and construction method of this product? If you want to know, let's take a look.

膨润土防水毯的作用和施工方法

Bentonite waterproof blankets are widely used and can be seen in many industries. In fact, bentonite waterproof blanket is a kind of geosynthetic material specially used to prevent the leakage of artificial lakes, landfills, pools, etc. When using this product, it can form many small fiber voids, so that the bentonite particles cannot flow in one direction. When it meets water, it will form a uniform and high-density colloidal waterproof layer in the pad, which can well prevent water leakage.

After understanding the function of bentonite waterproof blanket, let's take a look at the correct method of bentonite waterproof blanket in construction. The staff should know that the data of bentonite waterproof blanket has a large self-weight, so when selecting, a scraper should be selected to cooperate with the waterproof blanket lifting tool for handling and laying. The data connection of bentonite waterproof blanket is lapped. In addition, when laying on slopes greater than 10%, the number of lap joints along the length of the slope should be minimized as much as possible. In addition, the bentonite pad on the slope needs to be more than 1500mm beyond the toe line.

In addition to mastering these points, the staff also needs to know that any equipment for laying bentonite waterproof blankets cannot operate on geosynthetics. The outdoor air temperature should not be lower than 0°C or higher than 40°C during installation. Some exposed edges of the waterproof blanket will need to be immediately pressed down with sandbags or other heavy objects. As long as you master these correct construction methods, there will be no other problems.
