Application of Geomembrane sheet
Geosynthetic materials such as geomembranes have many applications due to their resistance to chemical substances, corrosion resistance, easy installation, long lifespan, high flexibility, suitable physical properties and cost reduction. /p>
pool sealing
Today, water reservoirs are very important in agriculture and animal husbandry and include pools that are used in gardening and farms or fish farming; But the pool is not only limited to these things, but the water reservoirs are very wide, which include swimming pools, man-made artificial lakes, washing ponds such as copper and ore, etc. Architects and builders of all types of pools prefer to use geomembrane sheets, an impermeable layer, to deliver a durable work with a long lifespan. In fact, geomembrane sheets are made of polyethylene and are used as insulation for water penetration in all kinds of pool structures.
Building Sealing
Building sealing has been an important issue for a long time; Because if water penetrates any part of it, it will cause serious damage to the structure and building over time. Before this, insulation was done using petroleum products such as Qirguni and Izogam; But their problems, such as leaving Izogam, still persisted. In recent years, geomembranes as a layer for sealing structures could find an important and large place in the market of sealing equipment.
tunnel sealing
Subways play an important role in urban transportation, and for this reason, the protection and maintenance of tunnels becomes very important, and their importance is not only limited to urban and mountain tunnels. Most tunnels have many challenges due to passing underground. They have the case of water and soil, one of the most important of which is preventing water from entering the tunnel. Nowadays, the builders of underground routes prefer to insulate structures with geomembranes, which is a durable and flexible polymer insulation, in order to avoid water infiltration into the tunnel and causing problems and costs in the tunnel structure.
Sealing the retaining wall
The retaining wall is actually a retaining structure that is used to preserve the building and prevent the structure from collapsing. In fact, this wall increases the resistance of the soil so that the lateral pressure due to unnatural slopes can be tolerated. Based on experience, half of the retaining structures will leak during the operation period, and this is the main reason why the sealing of retaining structures becomes important. The geomembrane layer is widely used in the insulation of retaining walls due to its impermeability and flexibility in construction.
Sealing tanks
There are many tanks for storing liquids, such as storing water or chemicals, oil, gas, etc., and the smallest leakage causes the waste of materials inside the tanks. One of the reliable methods to preserve the materials inside the tanks is the use of thin layers of polyethylene, that is, geomembranes. Covering geomembranes with their high impermeability properties help to preserve the materials inside the tanks.
Greenhouse insulation with geomembranes
Research shows that insulating greenhouses with geomembrane sheets using a layer of sun-resistant plastic keeps heat inside the greenhouse and prevents energy wastage. Geomembrane can be installed on the floor, walls and roof of the greenhouse to make the greenhouse warmer in winter and cooler in summer. Also, geomembranes can prevent the penetration of water and wind into the greenhouse or protect the greenhouse structure and plants from destruction.
Construction of Artificial Lake
Geomembranes in the construction of artificial lakes have advantages such as reducing costs, increasing efficiency and reducing environmental impact. The general method of constructing an artificial lake using geomembranes includes steps such as acceptability study, design and engineering, construction and installation, filling and commissioning.
in Roof Garden
Geomembrane sheets are used to prevent the penetration of water and plant roots in roof gardens. Geomembranes have advantages such as resistance to harsh environmental conditions, high mechanical strength, good welding ability, resistance to wear, chemicals and low cost compared to similar products. Also, this type of sheet is placed as a protective layer on the roof structure and other sub-layers such as plant layer, drainage layer and protection layer, and makes roof gardens able to create a sustainable green space in the urban environment.
Landfil
Landfills are places where garbage is buried. Although in recent decades, they have realized the value of waste and in fact, there should be materials in the landfill that can no longer be recycled, and recycled materials should be separated in advance and used many times in the recycling cycle; However, no matter how the waste is buried, its leachate must be removed in such a way that it does not enter the groundwater and does not pollute it. Therefore, the exit route of these materials must be designed in a safe and reliable way so that water does not enter the lower layers, i.e. soil, and then into the underground water. Therefore, the insulation of these routes and tunnels must be sealed, and today polymer layers of geomembranes are used due to their very high impermeability.
on roads and highways
Geomembrane sheets have different roles to control the flow of liquids or gases in geotechnical engineering projects such as roads and highways, the most important of which are to prevent waterlogging, filtration and reduce pollution.
