GEOTEXTILES
In the family of Geosynthetics, the most widely used products in Civil and Environmental works is non-woven Geotextile. VenusGeo is a brand of Venus Interlinings Pvt Ltd, that manufactures non-woven geotextiles that are made from PET or PP fibres bonded through the process of needle punching Further, thermal processes of calendaring or seinging can also be done over fabric, depending on its utility. It is widely used for the purpose of Separation, Drainage, Filtration, Protection, Reinforcement and Soil Erosion.
Functions
Reinforcement
VenusGeo offers commonly used geotextiles’ in a cost-effective way to overcome the low tensile strength of soil. They help in soil reinforcement, which results in improvement in embankment stability. They help in construction of steeper slopes by increasing the soil strength. These high strength structural geotextiles bear mechanical and hydraulic properties, which prevent the collapse of vertical earthworks & steep slopes.
Separation
VenusGeo is ideal for separating layers in any construction work. A strong & flexible geo is placed between the different layers to prevent migration & mingling of materials, yet allowing free movement of water. It increases bearing capacity and provided long term stability to the foundation. Separators between two kinds of soil are mostly needed where the ground is soft and unstable. Using separators reduces the amount of fill material required, increases durability of a structure and reduces the cost of maintenance.
Drainage
Uncontrolled & unchanneled water damages pavements, slopes and foundations. VenusGeo provides durable cost-effective solutions to control and channelize ground water. They have hydraulic properties, which help in draining out excess water, which is channelized through the plane of the fabric away from the construction and not by passing it across the fabric itself.
Filtration
Non-woven Geotextiles are permeable in nature. Hence, they are used in the process of filtration, whereby it allows water to pass through it without permitting movement of fine soil particles. This prevents clogging. Thus they act as a soil filter. These filters also separate two layers of granules during intense hydraulic activities. This helps in retaining its natural strength and losing minimum pressure.
Protection
VenusGeo is strong, durable and have the capacity to withstand pressure. They are puncture resistant and hence are ideal for protecting structures and fill materials from loads. They are placed below sealing materials to bear and distribute the pressure from the layers above. This protects the lower layer from bearing that stress and remaining concrete.
Applications
Geotextiles are primarily used in environmental & civil work. Because of its varied functions, it has applications in a no of areas:
Road Construction: Geo textiles are strong, durable and can handle load. Thus they are widely used in construction of temporary and permanent roads, airport runways & parking areas. Their drainage and separation property helps it to be used in road widening & asphalt maintenance.
Railways:Railway lines face heavy traffic of trains passing through them. This causes stress on the ballast and granular support. The rapid speed and weight of trains place heavy demand on the bearing course. Thus geotextiles are required to stabilize the foundation so that it can withstand the load. They are used for separation, filtration & reinforcement under the track bed. This also ensures long-term functionality of the tracks.
Tunnels: Modern traffic tunnels are planned for a service life of more than 100 years. Thus they must be well protected against the effects of groundwater and water penetrating from the top. Additionally, under-ground construction must also facilitate proper drainage and separation of granules. Geotextiles are used on both sides of membranes in tunnel construction to protect it from perforation. It protects the tunnel by waterproofing so as to increase the tunnel life. They are also used at underground levels.
- Construction Work: VenusGeo provides good drainage when used in building concrete floors, foundations, roofs, gardens & sports ground. They also help in suppressing sound. They are also used around pipelines for better drainage.
Hydraulic Work: Hydraulic Structures such as dams, riverbanks & coastlines face heavy hydrodynamic stress. To sustain this stress, VenusGeo is a cost-effective, durable & reliable solution. VenusGeo is an environmental product and hence it is widely used to protect the environment. Hence they are widely used for coastal protection, construction of harbours, dams, artificial lakes & water reservoirs. They also provide protection to riverbanks & canals and prevent soil erosion.
Drainage/Filtration: VenusGeo is used for building and protecting drains & pipelines. Their multiple functions prevents drain clogging by filtering soil fines and preventing dampness. Geotextiles are also widely used for construction of French drains.
Waste Disposal: VenusGeo, when used on both sides of the membrane, protects it from perforation. Thus it helps in waste disposal and water purification.
Soil Erosion: Fine pore size; high permeability and low potential for clogging are the main features of VenusGeo that helps in prevention of soil erosion. Flowing water can cause severe erosion and instability of soil structure. Thus VenusGeo when placed on the banks or elsewhere helps in maintaining the structure, without being affected by rainfall or surface water runoff. It can also be used in the form of fabrics and/or geobags.
Process
Non-woven geotextiles are made from PET or PP fibres bonded through the process of needle punching Further, thermal processes of calendaring or seinging can also be done over fabric, depending on its utility.
Specification
VenusGeo uses Quad Punch needle-punch looms from Morrisson, which can make fabric upto 6 meters in width and from 100 GSM to 1200 GSM in weight. We can further thermoset it as per customer requirement. On special requirement from customer we can also make fabric upto 2000 GSM.
