Drainage and isolation of tunnels with geomembranes
In the isolation and drainage systems of the tunnels, the geotextile layer is used as a protective and drainage of the geomembrane sheet. Generally, geotexis should be used that is well -resistant to chemicals and well -fluid and protect the possible injuries to the polymer layer, meaning good resistance to concentrated stress caused by sharp and winning bodies.
A way to cover the tunnel cover with a soft and thin coating is discussed here as a possible action to reduce seismic damage to the tunnels. Long -term earthquake observations on different tunnel sites in a variety of alluvial soil sediments have shown that a circular tunnel is exposed to deformity so that its two diagonal diameters passing through each other are repeatedly expanded and contracted. .
By restricting vibration modes to discuss this particular and important state, each of the essentials of the soil tunnel system – that is, soil, cover and tunnel cover – had only one degree of freedom that allows the effect of isolation to simply in a limited number. Be evaluated from key parameters
Sealing and isolation of tunnels with geomembranes
Tunnel sealing to preserve tunnel structures from leaking water to them and preventing and possible demolition of structures due to water penetration and implementation of geomembrane sheets with branded branded tunnel sealing and gearotoxist implementation for infrastructure To prevent damage to the geomembrane sheet.
Implementation of isolation of tunnels with geomembranes
The sale of materials and implementation of insulation and drainage systems of tunnels that have passed through the underground and the possibility of entering water into them is one of the specialized services of the Group of Soil Engineers.
In this regard, our engineers use the up -to -date technology and the conditions prevailing in each project use the following combination of 2 or more geographical materials.

Sustainable Structure Structure
The insulation of underground structures in areas facing surface water, subsurface water, moisture leakage, etc. is one of the very serious problems of buildings that resolve the problem with its properties.
The major applications of this product include the insulation of urban tunnels, railways, subways, subways and more.
One of the most important features of this product is the resistance to perforation and soil oxidation resistance.
Using the most advanced industrial machinery, the company manufactures this product in single -layer and multi -layer production in thicknesses of 1 to 2 mm.
PVC geomembranes is made of polymer polymer and softening materials and stabilizing additives. PVC geomembranes are anti -acid and moisture -anti -moisture and have flexibility and proper length (up to 3 times).
