In the process of constantly pursuing innovation and sustainable development in the construction industry, nonwoven fabric, a seemingly ordinary material, is emerging with its outstanding characteristics. From roof waterproofing to wall insulation, to foundation reinforcement and other key links, it contributes indispensable strength to the improvement of building quality and has become an “invisible hero” in the construction field.
Roof waterproofing: building a solid defense line
Roof waterproofing is related to the overall durability and living experience of a building. Even a slight mistake can cause leakage, leading to a series of problems such as moldy ceilings and damaged walls. Traditional waterproofing membranes often wrinkle and rupture during construction and use due to poor bonding of the base layer, susceptibility to temperature and building settlement. The intervention of non-woven fabric effectively solves these problems.
Laying non-woven fabric is a crucial step in roof waterproofing construction. Its fiber structure is fine and soft, resembling a delicate “adhesive” that tightly covers the surface of the base layer, filling in tiny pores one by one, greatly enhancing the bonding stability between the waterproofing membrane and the base layer. When the external environment changes, such as significant temperature fluctuations or slight settlement of buildings due to geological conditions, the good flexibility of non-woven fabric comes into play. It acts as an elastic cushion, absorbing stress and preventing the waterproofing membrane from breaking due to excessive stretching, significantly extending the service life of the roof waterproofing system.
Taking a commercial office building in a coastal city as an example, the roof of the building adopts a composite waterproofing scheme of “SBS waterproofing membrane+non-woven fabric”. After years of typhoons and rainstorm, the roof is still watertight, and the waterproof performance is stable and reliable. Compared with buildings in the surrounding area that use traditional single waterproofing membranes, the leakage rate is significantly reduced. After professional testing, non-woven fabric has increased the bonding strength between the waterproofing membrane and the base layer by about 35%, and reduced the occurrence of roof leakage by 75%, fully demonstrating the significant advantages of non-woven fabric in roof waterproofing.
Wall insulation: guarding indoor temperature
In the current promotion of green and energy-saving buildings, wall insulation is an important measure to reduce building energy consumption and improve living comfort, and non-woven fabrics also play a key role in this field.
When constructing the wall insulation system, covering the outside of the insulation board with non-woven fabric can have multiple effects. During the construction process, it can prevent insulation materials from scattering, avoid material waste and environmental pollution, and ensure the integrity of the insulation layer, making the insulation effect consistent. The unique breathability of non-woven fabric is also a major highlight. It allows water vapor inside the wall to be smoothly discharged, avoiding the accumulation of water vapor that can cause the insulation layer to mold or deteriorate, thereby reducing the insulation efficiency. When facing frequent fluctuations in outdoor temperature and exposure to ultraviolet radiation, non-woven fabric acts as a loyal guardian, buffering temperature shocks, resisting ultraviolet erosion, protecting insulation boards from mechanical damage, extending their service life, and helping buildings achieve energy-saving and emission reduction goals.
A residential community in the north chose a solution of using rock wool insulation board combined with non-woven fabric for exterior wall insulation renovation. After the renovation, according to professional institutions’ testing, during the winter heating season, the indoor temperature of the houses in this community increased by an average of 2-3 ℃ compared to surrounding communities that did not adopt this scheme. There was no mold or condensation on the wall surface, and residents were satisfied with the indoor insulation effect as high as 96%, which effectively reflects the practical value of non-woven fabrics in building insulation.
Foundation reinforcement: stabilizing the foundation of the building
A stable foundation is the foundation for building safety, and non-woven fabric plays a unique and important role in foundation reinforcement projects. When dealing with complex geological conditions such as soft soil foundations, multi-layer non-woven fabrics are often combined with sand, gravel, geogrids, etc. to construct composite foundation structures.
Non woven fabric has high tensile strength, which can evenly disperse the huge load transmitted from the upper building, enhance the stability of the foundation soil, and effectively prevent uneven settlement of the foundation. Its excellent filtering performance can prevent soil particles from being lost under the action of water flow, avoiding serious problems such as foundation collapse caused by soil erosion. In the drainage process, non-woven fabric can work in conjunction with drainage pipes to accelerate the discharge of excess water from the foundation, greatly shorten the consolidation time of the foundation, significantly improve the bearing capacity of the foundation, and provide solid support for the stable rooting of buildings.
The foundation construction of a large bridge project can be regarded as a typical case. The foundation is located in a deep soft soil layer area and adopts a reinforcement scheme of “non-woven fabric+sand and gravel piles+drainage boards”. During the construction period, the foundation settlement was precisely controlled, and the bridge was successfully built and put into use. Long term monitoring data shows that the settlement of the bridge foundation is far below the design allowable value, and there are no abnormal conditions such as cracks or collapses on the surrounding ground, fully verifying the reliable performance of non-woven fabric in foundation reinforcement and highlighting its important value in ensuring the safety of construction projects.
From the roof to the walls, and then to the foundation, non-woven fabrics play an irreplaceable role in various key parts of buildings, contributing to improving building quality and achieving green and energy-saving goals. With the continuous development of the construction industry, the requirements for material performance are becoming increasingly stringent, and non-woven fabrics will continue to upgrade and innovate, shining brighter in the field of construction, creating a safer, more comfortable, and environmentally friendly building environment for us.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
