How should the house be waterproof?

In the process of home decoration, ensuring proper waterproofing is a crucial step that should not be overlooked. A well-executed waterproofing system not only enhances your living comfort but also significantly extends the lifespan of your home. Poor waterproofing can lead to serious structural issues, and in extreme cases, it may even result in damage that could compromise the safety of the entire building. When you decide to renovate a new house, it's important to note that any plumbing work typically involves modifying or removing the original waterproof layer installed by the developer. This makes it essential to reinforce the waterproofing to protect your investment and avoid potential disputes with neighbors. Therefore, waterproofing is a must during any new home renovation. The cost of waterproofing is relatively low compared to the overall renovation budget—usually between $60 to $100 per square meter, which accounts for about 1% of the total cost. Despite this small expense, the long-term benefits are significant. Ignoring waterproofing can lead to major problems. Water is highly mobile and can easily travel through walls and floors, causing leaks that affect lower floors and neighboring units. If water damage occurs due to poor waterproofing, the repair costs can be 3 to 5 times higher than the initial waterproofing expenses. Not only does this cause financial strain, but it can also lead to legal complications and serious inconvenience in daily life. Key areas that require waterproofing include bathrooms, kitchens, balconies, and the first-floor areas of houses. Additionally, basement floors and all surrounding walls should also be protected against moisture. The standard method used by professional contractors involves preparing the surface by leveling it, cleaning thoroughly, and allowing it to dry before applying the waterproof coating. The coating is then applied evenly, and tiles are installed afterward. However, some unscrupulous contractors may try to cut corners by using cheaper alternatives like asphalt instead of proper waterproofing materials. Asphalt is much less effective and can be misleading to homeowners who may not know the difference. For example, asphalt costs around $4.47 per kilogram and covers only about 2 square meters per kilogram, making it an unwise choice for long-term protection. In contrast, high-quality waterproof coatings, such as those from reputable brands, cost approximately $20.63 per kilogram. When used according to instructions, they cover about 2.5 kilograms per square meter, resulting in a cost of roughly $51.58 per square meter. These products provide reliable waterproofing performance and are worth the extra investment. Reputable decoration companies typically use these high-quality materials to ensure project quality and maintain their reputation. They often offer a one-year warranty on their work, and if issues arise due to improper waterproofing, the company is responsible for the repairs. On the other hand, unlicensed or "guerrilla" contractors may skip essential steps to save money, leaving homeowners to deal with the consequences later. Therefore, when choosing a decoration company, it's vital to do your research and ensure they use proper waterproofing materials. Always ask questions, inspect the materials, and verify the contractor’s credentials before signing any contract. Taking these precautions can save you from costly repairs and unnecessary stress in the future.

Rotor Pump With Rectangle-inlet

We are a world-leading technology-based enterprise focus on R&D and manufactures non-Newtonian fluid conveying equipment. We specialize in rotary pumps, homogeneous pumps and grinding pumps. We have obtained 11 invention Patents and 46 practical patents, and won many national honorary titles.


Twin-rotor lobe pump are multi-functional and bi-directional positive displacement pumps, produced with fine technology. These products use synchronic rotors, driven by a pair of synchronic gears in the gear box. Transmitted by the main shaft and the sub-shaft. The rotors move synchronically in counter-clockwise a directions, which, consequently, varies the pump capacity and builds up high vacuum capacity and emission pressure. It is particularly suitable to pump sanitary medium, high-corrosive and high-viscous medium.


Rotor pump with with rectangle-inlet: The inlet design is V-inlet, enlarge the inlet diameter, convenient for high viscosity medium enter pump body. Suitable for high viscosity or thickness medium, such as moon cake filling, bean paste filling and other medium with poor fluidity.
