Geo-Omran Sustainable Structure Variety and product quality, price suitability, sales and implementation Designer, executor, and manufacturer of geosynthetics in civil engineering, construction, road construction, oil, gas, and petrochemical industries
Manufacturer and executor of various PVC sheets and randle and bolt covers for insulation and sealing of various construction joints, metro tunnels, underground tunnels, and building pits. Equipped with technical specification sheets and up-to-date international standards.
Advantages of sealing, insulation, and drainage of tunnels and underground structures using geosynthetics: Reduction of risk in accidents caused Acceptable reduction in execution costs compared to traditional methods Significant reduction in repair and maintenance costs High compressive strength, flexibility, and very high speed of execution and implementation Low thickness, high water conduction capacity, light weight, and long lifespan of geosynthetic products
Sealing, insulation, and drainage stages of tunnels and underground structures with the help of geosynthetics: Cutting or covering the heads of nailing or reinforcements Considering the presence of nailing and reinforcements, the floor and wall surfaces must first be completely smooth and even for the implementation of geomembrane and geodrain layers. Covering the heads of nails with cement slurry and cutting the nail heads as much as possible and using several layers of geotextile to cover them is very effective for this purpose. Implementation of the first geotextile layer: Applying one layer of geotextile at this stage plays two essential roles: 1- Filter: to prevent clogging of pores and drainage network by gravel and mud 2- Water conductor towards drainage: Geotextile absorbs moisture and directs water towards the upper layer (geodrain). Implementation of drainage layer (geodrain): To direct water towards drainage pipes and transfer it outside the tunnel, geodrain layers (dimple sheet or 3D CVF layer according to expert opinion) are used. Implementation of geomembrane: Implementation of PVC, LDPE, or GCL geomembrane layer according to consultant and designer. Geomembrane welding: Welding of geomembrane sheet edges in overlaps and testing welding points. Implementation of the second geotextile layer: To protect the geomembrane against the concrete layer, another high-weight geotextile layer is used. Implementation of waterstops: For complete sealing, various bentonite and PVC waterstops are used. Implementation of protective concrete: After the above steps, protective concrete is implemented and the project continues.
