What Is the Basement Membrane?

The basement moisture-proof layer refers to the method used in the basement to prevent moisture. The moisture-proof layer is a layer of material provided to prevent moisture in the soil below the ground from entering the brick wall. Moisture-proof layer structure plan: vapor barrier film + thermal insulation layer + waterproof breathable film.

Basement moisture barrier

Many people will remember the mention of the tide in the basement, because people who have the basement have been troubled by the moisture-proof problem in the basement. If you have used a basement, then you will not be unfamiliar with the phenomenon of ground floor and wall resurgence. Before the emergence of the moisture-proof liquid, the moisture generated by the returning moisture from the basement floor and wall surface will generally cause people great trouble. It will corrode the items we store in the basement, cause the items to crack, mold, and breed a lot of bacteria. . If our products are stored in the basement, moisture will deteriorate our products; if we live in the basement, a humid environment will reduce the quality of our lives, cause a lot of discomfort to our bodies, and cause us inestimable losses. And how many of us have considered eliminating basement moisture in the past? Even if they think of it, how many people know how to eliminate the moisture in the basement reasonably? This leads to the concept advocated by the moisture-proof layer in the basement-the moisture-proof basement is moisture-proof.

To stay away from moisture, all we can do is to reasonably make the basement floor and wall moisture-proof. It is very easy to confuse the concepts of moisture and water, and often use waterproof materials and construction methods to deal with moisture problems. This not only fails to obtain the ideal moisture-proof effect, but often results in irreparable consequences. What the moisture-proof needs to solve is to prevent the moisture (water vapor), that is, the problem that the moisture enters the room, and the waterproof solves the problem of preventing liquid water from penetrating into the room. Generally, the requirements for moisture resistance are much higher than those for waterproofing. The molecular density of the waterproof layer is difficult to prevent water vapor from passing through. Moisture prevention is a concealed project that needs to be handled on the base surface. If problems are found after renovation, it is usually very difficult to make up for, and the price paid is also high. After many people understand the moisture-proof liquid, a new understanding of the ratio of moisture-proof investment to effectiveness immediately emerges.

The basement is moisture-proof and has become a problem in the field of waterproofing. However, in the opinion of moisture-proof experts, the moisture-proof liquid is fully capable. We need healthy professional floor and wall moisture-proof materials. It is all inorganic material and is soluble in water, so it does not have any volatiles and has no toxicity. It is colorless, odorless, and can be in direct contact with human skin. Construction is simple, as long as you spray two on your existing concrete base, it will penetrate into the cement to form a dense 20-30mm moisture-proof layer. So as long as your base surface is still there, your base surface has permanent moisture resistance.

So far, the basement can only use moisture-proof liquid. It is a reactive inorganic floor moisture-proof product compounded by patented formula. The special moisture-proof liquid on the ground can penetrate into the cement, and under the action of air, it will react to form elastic gel particles. Over time, the gel particles will become more and more large, which will block the capillary seams inside the cement and form a permanent moisture-proof layer. These elastic gel particles are a dynamic structure that will swell when it encounters water vapor. Since it is a flexible body and has the ability to adapt to the shape of the pipe slit, it can effectively prevent water vapor from passing through. Its working principle is similar to the sealing plug. It is resistant to acid and salt-alkali corrosion. Due to the excellent sealing properties of the moisture-proof layer, it can well inhibit bacterial growth. It is different from ordinary water-proof materials. It plays a real moisture-proof effect. The moisture-proof layer it produces is integrated with cement instead of being attached to it, so it has a permanent service life and will not have Worries about falling off and destruction. It is easy to apply and can be applied with a normal sprayer.

Moisture-proof liquid is specially used for moisture-proof in the basement. It has super moisture-proof function and has permanent moisture-proof performance.

Colorless, odorless, the material itself is inorganic and free of volatiles, and has no adverse effects on human health;

It is not limited by the shape of the base surface, has good edge sealing, and can achieve the overall moisture-proof effect of "structural moisture-proof integration";

Simple construction and simple construction tools, as long as ordinary sprayers can be used to achieve good construction results; there is no need for any professional construction skills, as long as you can water flowers, you can do moisture-proof construction;

The construction cost is low and the cost performance is extremely high. As long as you spend one third of the cost of the waterproof layer, it can play the dual effect of moisture resistance and waterproof;

The service life is the same as that of the ground. As long as you do not damage your construction base, your moisture-proof layer will be permanently effective; it is integrated with your base and has sufficient thickness without blistering and cracking. Worry. The original moisture-proof layer was damaged due to nailing and other reasons. The product still has a repair function when it encounters water vapor.

Resistant to salt, alkali, acid and other chemical substances;

Because of the tightness of the moisture-proof layer, it is difficult to breed bacteria on its surface, so it has a good antibacterial function.

The first step: the special floor moisture-proof liquid can penetrate into the concrete about 20-30mm under the drive of water, and react with some substances in the atmosphere to form elastic gel particles. With time, the particles will become more and more More and more, when it is saturated, the gel particles can completely block the capillary pores of the cement.

Second step: These gel particles will automatically expand when encountering water vapor. Because it is a flexible body, it has the ability to adjust its shape. With the increase of the underground pressure, the gel particles can adapt to the shape of the pores in the cement. Seal the cement surface.

The third step: the stronger the underground moisture, the higher the air pressure, the better the tightness of the cement capillary pores, the principle of action is like a rubber sealing plug.

Provide non-toxic test report and performance test report;

The color of the base surface after construction can be different from the unconstructed base surface in 3-4 days; the surface of the base surface after construction is in a semi-dry state after 7 days; after 15 days of construction, the surface color is obviously white, It is fully dry; as time goes by, the moisture-proof effect will become better and better, and the basic moisture-proof capacity will be reached after three months;

All construction surfaces to be treated must be cleaned first to ensure that there is no dust, dirt, organic resin, paint and other pollutants that affect the product's depth. New concrete can be used after demoulding;

Cracks and holes with a surface diameter greater than 0.2mm shall be repaired with cement;

Shake well before construction and then use low-pressure spraying to make the base surface reach a wet saturation state of about 1 minute.

The construction is divided into two passes, and the interval between each pass is preferably 1 hour. The theoretical coverage rate is 4m / liter. The actual coverage rate will vary depending on the construction method, the construction environment, and the roughness of the base surface.

1-2The gel formation process is 1-2 hours after construction. Avoid frequent stepping, and it can be passed after 24 hours (or the surface is dry);

Other sub-items such as painting and finishing can be performed after 4-7 days of construction.

Repair should be repaired if damaged within 1-2 hours after construction;

Avoid spraying on glass and metal materials;
