How to choose suitable waterproof materials based on the climate and the selection of waterproof materials.

With the progress of today's society, new types of waterproof materials are constantly being developed and sold in the market. The selection of building waterproof materials is not necessarily based on the better the waterproof material, the better its function. In the selection of waterproof materials, suitable waterproof materials should be chosen according to the design and practical situation. When choosing materials, the principles should be followed. Waterproof materials have good performance, good material stability, and are required to be easy to store and transport, easy and flexible to construct, with a long service life. The material price is moderate. In short, in the selection of each material, appropriate materials should be selected according to the location, conditions, environment, building grade, and functional needs of the project. Because each material has its own characteristics, and different buildings can make it suitable. The characteristics of the material are well utilized, To achieve good waterproofing, SBS waterproofing membrane can be used.

1. Selection of roof waterproofing materials. Due to comprehensive factors such as mechanics, physics, chemistry, etc., the roof is mainly affected by long-term exposure to freeze-thaw cycles, thermal expansion and contraction, dry and wet changes, as well as the effects of sunlight, ultraviolet radiation, ozone, wind, frost, rain and snow erosion and weathering, as well as some structural effects such as temperature differences and stretching of waterproof rolls or coating bodies during construction, which can cause premature damage to the roof. Therefore, it is necessary to choose materials with good aging resistance, extensibility, and high heat resistance. In the selection of roof waterproofing materials, polyester tire modification should be chosen. Materials with characteristics such as asphalt rolls, EPDM sheets, or asphalt felt.

2. Selection of underground waterproofing materials. Due to the long-term humidity and difficulty in maintenance, as well as the small temperature difference, the underground PVC waterproofing membrane project requires excellent waterproof materials with good impermeability, elongation, and overall water resistance. It also requires flexible materials that are resistant to mold and corrosion. For example, when using polymer waterproofing substrates, it is necessary to choose adhesives with good water resistance, and the thickness of the substrate should not be less than 1.5 millimeters. For example, for polymer self-adhesive film waterproofing membranes and other materials, the thickness should not be less than 2.5 millimeters. Generally, for every additional waterproof layer added indoors, inorganic rigid waterproof materials such as cement-based materials are suitable.

3. The selection of waterproof materials for toilet and bathroom areas is generally small. The waterproof materials selected for waterproofing projects should be based on the following principles: firstly, they should be suitable for changes in the shape of the base layer and conducive to the laying of pipeline equipment. Secondly, TPO waterproof rolls should be non permeable and seamless as a whole coating. The purpose of this is to address various factors such as small toilet and bathroom area, multiple pipe holes, sanitary equipment, and the complex connection structure of the ground, floor, and wall.

When choosing waterproof materials, there are also certain requirements for climate selection. What are the specific requirements for selection? Let me take you to understand.

1. China has a vast territory with a significant temperature difference between the north and south. In the Jiangnan region, the summer temperature can reach over 40 degrees Celsius, lasting for several days. When exposed to the waterproof layer on the roof, prolonged exposure to sunlight can prematurely promote the waterproof function. The selected waterproof material should be UV resistant and have a high softening point.

2. It is rainy in the south, snowy in the north, and dry in the west, with an annual rainfall of over 1000mm in about 15 provinces, municipalities, and autonomous regions. For 200 days of continuous rainy days, the roof is always wet, with poor drainage and water accumulation. It has not dried for several months and is soaked in waterproof layers. Coatings with poor water resistance are prone to re emulsification or hydration reduction reactions, and adhesives that are not resistant to water bubbles seriously reduce the bonding strength, causing the polymer roll material of the bonding joint to crack, especially in the internal drainage gutter. I should choose water-resistant waterproof materials for this reason.

3. In the arid and rainless northwest region, evaporation is much greater than rainfall, and there is often no water from the eaves after rain. These areas obviously have a reduced degree of waterproofing, and a second level building can also meet the waterproofing requirements. If a protective layer is done well, it can achieve a durable life.

4. In extremely cold and snowy areas, some waterproof materials cannot withstand the cyclic changes of low-temperature frost heave and shrinkage, leading to premature aging and fracture. Four liquid rolls are covered with white snow for five months in a year, and the waterproof layer is soaked in snow water for a long time. At the same time, the snow melts and freezes, and the frost resistance is not strong. Adhesives with poor water resistance will also fail. If waterproof materials that are not resistant to low temperatures are selected, inverted roofs should be constructed.

5. The waterproof construction season cannot be ignored. In the North China region, the season is also very cold, and water-soluble coatings cannot be used. Adhesives will reduce their bonding performance at 5 ℃, and construction cannot be carried out at temperatures below zero. When designing, it is summer, and during waterproof engineering construction, the adhesive will freeze and lose its bonding strength when it encounters concrete, causing the joint of the roll material to fail, delaying the construction period, and requiring miscellaneous materials. In the summer of Northeast China, waterproof materials that are afraid of cold can be used. However, in the harsh winter, these completed waterproof layers cannot withstand the damage of frost heave and contraction, and will fail prematurely. When designing, attention should be paid to understanding the temperature adaptability of the selected materials.
