Needle-punched "Dornit": where and how to use this material
“Dornit” is a synthetic material based on polypropylene or polyester fibers. In Russia, its release began in 1980. The basis for the development and production of geotextiles lay the French technology for making non-woven fabric.
Key Dornit Benefits
The most durable in the range of materials recognized "Dornit", made by needle-punching technique only from polypropylene yarn. It is distinguished by the most extensive use, and a number of operational advantages:
- ultimate strength;
- resistance to vibration, chemical reagents;
- excellent filtering and heat insulation properties;
- environmental friendliness.
Equally important is the resistance of geotextiles to thermal vibrations. It is capable of maintaining its parameters in the temperature range from -60 to +100 degrees.Synthetic raw materials make "Dornit" immune to biological agents, mold, fungus.
Main Industries of Material Use
The fact that they are made in the needle-punched way determines all the industries of its application. The production technology gives the material filtration properties: it perfectly holds the soil, and at the same time it does not prevent the passage of water through it. The effectiveness of Dornita as a barrier to the growth of grass roots, flowers, and weeds has also been proven. The combination of useful properties makes Dornit indispensable for the construction of roads, railroad tracks, strengthening slopes and slopes, arranging foundations, creating drainage systems, and laying pipelines. In road construction, “Dornit” significantly increases the carrying capacity of coatings by preventing the mixing of weak soils with the substrate (sand, crushed stone). The overall life of the tracks with geotextiles increases, and the costs of their arrangement and maintenance are reduced. The material is also used as a base layer when laying paving slabs, paving stones, and arranging foundations for various residential and commercial objects. In Drainage drainage systems it plays the role of a natural soil filter.The material prevents the soil from washing out and creates the most favorable conditions for the cultivation of vegetable and cereal crops. Due to its structure, geotextiles do not clog for years, retaining their filtering properties at the initial level. The minimum service life of a nonwoven fabric is at least 20-25 years.
