The "loyal guard" guarding construction materials
There are a large number of different types of construction materials piled up on construction sites, each of which has specific requirements for environmental conditions, and heavy-duty reinforced waterproof tarpaulin provides them with an ideal protective environment.
"Moisture-proof armor" for cement
Cement is one of the most basic and critical materials in construction. It is extremely sensitive to humidity. Once it is damp, cement particles will undergo hydration reaction, then agglomerate and harden, completely losing its proper gelling properties. According to relevant studies, if cement is exposed to an environment with humidity exceeding a certain proportion for a period of time, its strength will be significantly lost. If it continues to be in a high humidity environment, it may eventually cause the cement to be completely scrapped. This risk is particularly prominent in areas with frequent rainy seasons. The emergence of heavy-duty reinforced waterproof tarpaulin effectively solves this problem. Its excellent waterproof performance can withstand a high static waterproof column height, like an indestructible layer of armor, completely isolating rainwater from cement. At a large construction site, the construction party used heavy-duty reinforced waterproof tarpaulin to cover a large amount of cement. After a rainy season, the cement in the area not covered by the tarpaulin became damp and agglomerated, making it unusable, causing great losses; while the cement covered by the tarpaulin was well preserved, providing a solid guarantee for the smooth progress of the project. At the same time, the tight weaving structure and special coating of the tarpaulin can also prevent the slow penetration of moisture in the air, further ensuring the stability of the quality of the cement during storage.
"Rust-proof shield" for metal materials
Metal materials such as steel and aluminum alloys play an important role in building structures. They are very easy to rust and corrode by chemical reactions with oxygen and moisture in the air. Rust not only damages the appearance of metal materials, but more seriously, it will cause its mechanical properties to decline, reducing the bearing capacity and safety of the structure. Research data shows that steel will corrode to a certain extent every year in a humid environment. If the corrosion is severe, the bearing capacity of the steel may be reduced by a large proportion. Heavy-duty reinforced waterproof tarpaulins can create a dry space for metal materials that is isolated from external erosion. Taking a bridge construction site as an example, a large amount of steel used in construction needs to be stored in the open air. The construction team used heavy-duty reinforced waterproof tarpaulins to fully cover the steel. After a long construction period, there were only slight oxidation marks on the surface of the steel, and almost no rust, which greatly guaranteed the quality and service life of the steel and laid the foundation for the sturdiness of the bridge. In addition, the durability of the tarpaulin makes it difficult to break during frequent handling and loading and unloading, and always provides reliable protection for metal materials.
The "ideal choice" for building temporary sheds
On construction sites, it is crucial to provide construction workers with a safe and comfortable temporary rest and tool storage space. The sheds built with heavy-duty reinforced waterproof tarpaulins perfectly meet these needs.
"Safe haven" in wind and rain
The construction site environment is complex, and weather changes have a great impact on the work and life of construction workers. Strong winds and rainstorms may suddenly strike, and ordinary simple shelters are difficult to resist. Heavy-duty reinforced waterproof tarpaulins have become a reliable guarantee for dealing with bad weather with their excellent wind resistance. It has a large weight, strong stability in the wind, and is not easily lifted. Its thickness and material strength are enough to withstand the tearing of wind. At the same time, the evenly distributed eyelets or hanging rings around the tarpaulin, combined with ropes, ground nails, windproof ropes, windproof poles and other auxiliary facilities, can firmly fix the shed to the ground. During a typhoon warning, a construction site built a temporary shelter shed with heavy-duty reinforced waterproof tarpaulin in advance. After the typhoon, some simple sheds in the surrounding area that were not built with such tarpaulins were blown to pieces. Although the shed on this site was slightly shaken, the overall structure remained intact. The construction workers safely passed the typhoon in it, which fully demonstrated the strong protective ability of the heavy-duty reinforced waterproof tarpaulin.
Comfortable "resting space"
In addition to resisting wind and rain, the shed built with heavy-duty reinforced waterproof tarpaulin can also provide a relatively comfortable resting environment for construction workers. In the hot summer, the tarpaulin can block some direct sunlight, reduce the temperature in the shed, and reduce the feeling of stuffiness; in the cold winter, it can also play a certain role in heat preservation and block the invasion of cold wind. The good waterproof performance of the tarpaulin ensures that the shed is always dry, avoiding physical discomfort caused by the humid environment for construction workers. At a subway construction site in a certain city, the construction workers have limited rest areas due to the narrow construction site. The shed built with heavy-duty reinforced waterproof tarpaulin effectively utilizes the space, provides a dry and comfortable resting place for the construction workers, and improves the work enthusiasm and work efficiency of the construction workers.
“Solid barrier” for construction structure protection
During the construction process, some structures that are under construction but not yet completed require temporary protection, and heavy-duty reinforced waterproof tarpaulin plays an important role in this regard.
“Maintenance assistant” for concrete structures
Maintenance after concrete pouring is crucial and directly affects the strength and durability of concrete. During the curing period, concrete needs to maintain proper humidity and temperature. Heavy-duty reinforced waterproof tarpaulin can be covered on the surface of the newly poured concrete structure to play a role in moisture retention and heat preservation. On the one hand, it can prevent water from evaporating too quickly, provide sufficient water for the hydration reaction of concrete, and promote the growth of concrete strength. Studies have shown that during the concrete curing process, maintaining humidity can significantly improve the strength of concrete within a certain period of time. On the other hand, the tarpaulin can regulate the temperature of the concrete surface to a certain extent, avoiding cracks in the concrete due to excessive temperature changes. In a high-rise residential construction project, the construction party used heavy-duty reinforced waterproof tarpaulins to cover and maintain each newly poured concrete floor. After testing, the concrete strength of the project met the design requirements, and the crack incidence was significantly lower than that of similar projects that did not use tarpaulins for maintenance, effectively ensuring the quality of the building structure.
"Protective fortress" for unfinished buildings
For some large-scale construction projects, the construction period is long. During the construction process, the unfinished building structure is easily eroded by natural factors such as wind, rain, and dust. Heavy-duty reinforced waterproof tarpaulins can fully cover these unfinished buildings and protect the building structure from external damage. For example, in the construction of a large commercial complex, due to the arrangement of the construction schedule, some of the main buildings were not completed before the arrival of winter. The construction team used heavy-duty reinforced waterproof tarpaulins to cover the unfinished parts tightly, which not only prevented the erosion of the building structure by rain and snow in winter, but also blocked the entry of dust and debris, providing a good foundation for subsequent construction, reducing the workload required for repairs due to structural damage, and speeding up the construction progress.
Key points for choosing heavy-duty reinforced waterproof tarpaulins for construction sites
Determine the size and strength according to construction requirements
When using heavy-duty reinforced waterproof tarpaulins on construction sites, the appropriate size and strength must first be determined according to specific construction requirements. For tarpaulins covering large areas of building material piles, it is necessary to ensure that their size is sufficient to completely cover the materials, and a certain margin is reserved for fixing and wrapping. For example, in a site where a large amount of steel is piled up, the size of the tarpaulin should be a certain proportion larger than the steel stacking area to ensure that the steel can be fully wrapped and firmly fixed. For tarpaulins for building sheds, they should be selected according to the design size of the shed and the number of people expected to be accommodated. At the same time, the actual use intensity of the construction site should be considered, such as the friction and pulling that frequent material handling may cause to the tarpaulin, and tarpaulins with high strength and good wear resistance should be selected. For areas that may collide with the tarpaulin during the lifting of materials, thickened and reinforced tarpaulins should be selected to ensure their service life in a high-intensity use environment.
Pay attention to materials and waterproof performance
The material directly determines the performance of the tarpaulin. Common PVC coated fabrics and waterproof nylon fabrics are widely used on construction sites. PVC coated fabrics have good weather resistance, and the polyvinyl chloride coating on its surface can effectively prevent water, sun and corrosion. When choosing, make sure that the coating is uniform and firm, without bubbles or peeling. Waterproof nylon fabrics have the characteristics of high strength, light weight and excellent mildew resistance. They are suitable for scenes with certain weight requirements and need to be used in humid environments for a long time. In terms of waterproof performance, it is necessary to choose tarpaulins with a high waterproof grade, such as products that can withstand higher static waterproof column heights, to cope with the complex and changeable weather conditions on construction sites, especially in rainy seasons or areas with heavy rain.
