What is the best solution to water seepage in exterior walls?
Water seepage in the exterior walls on rainy days is a common phenomenon in life, especially in some old residential areas. The exterior walls are in disrepair for a long time, and the waterproof layer is aging or damaged, which will cause leakage in the exterior walls and penetrate into the interior walls, causing the interior walls to become damp and moldy, the wall skin to fall off, and harmful odors to be produced, causing certain harm to the health of the body. So what is the best solution to water seepage in the exterior walls?
1. Apply cement-based penetrating crystalline waterproof coating to the cracks of the exterior wall. After the waterproof coating solidifies into a film, it has certain ductility, impermeability and weather resistance, which can play a role in waterproofing and protection. When applying the waterproof material, apply it at least 3 times, and apply the next one after each layer is completely dry. This can ensure that the waterproof material plays a good waterproof role. The qualified standard is that a uniform layer of crystals can be seen on the wall.
2. Spray the penetrating waterproofing agent on the places where water is seeping on the exterior wall. It can quickly cover the cracks in the wall and form a waterproof layer. The waterproofing agent slowly penetrates into the interior of the concrete and reacts with the alkaline substances in the cement mortar to form crystals, which play a role in waterproofing and patching the pores and cracks in the concrete.
3. The only way to completely solve the problem of water seepage in the exterior wall is to re-waterproof the exterior wall. This not only solves the problem of water seepage in the exterior wall, but also reinforces the weak points of the waterproof layer and enhances the effect of the wall waterproof layer.
