    Geotextiles solutions for hydraulic constructions sector

    Water is irreplaceable for life and for a great many businesses. It is a guarantee of survival and a scarce resource. Today`s society demands increasingly large volumes of increasingly high-quality water. TenCate Geosyntehtics has had a constant hand in the creation of water management infrastructure. In the last 20 years it has built more than 30 dams of a wide range of types and has used for that purpose the most modern of construction systems. TenCate filtration systems offer optimized hydraulic properties with high compression strength. Sensitive hydraulic structures - dams, dykes, canals, reservoirs - require perfect water control. Whether used to protect banks, around a drainage structure or against clay sealing cores, TenCate filtration geosynthetics achieve this level of requirement.

    Monitoring of hydroelectric dam sumps

    The Situation

    Hydroelectric dams produce electric power by harnessing the force of the water flowing through the dam. There are numerous sources for oil spillage:

    • The hydroelectric turbines are lubricated by lubrication oils.
    • The very large water control valves are normally hydraulic powered and are lubricated with various greases and oils.
    • Vehicles including fork lifts, trucks, etc., can spill oils and fuels.

    Any accidental spillage of oil or grease or intentional wash down water containing minor amounts of oils, greases, and detergents must be collected and treated before discharge to the river. These fluids along with any water leaks are collected in sumps in the dam and are regularly pumped out. In many cases, the volume of water is substantial.

    Erosion & stormwater control solutions for the roads & highways sector

    The GEOWEB system offers design flexibility for unpaved roadway surfaces, base stabilization, road shoulders as well as erosion protection of embankments and stormwater drainage channels. The 3D GEOWEB structure offers strength improvements to the road base layer for asphaltic and concrete pavements far greater than delivered by geogrids. A single GEOWEB layer performs well over soft subgrades - while geogrids require 2-3 layers for the same benefit - saving cost and construction time. Unpaved roads built with the GEOWEB system are permeable, and require 50% less infill. Roadway slope and channel designs include vegetation, aggregate or concrete protection.

    Amphibious multipurpose dredger for maintaining and cleaning industrial ponds

    Maintenance is easily done by utilizing Watermaster`s suction dredging capabilities and independent moving capabilities.

    Watermaster is easy to transport to the site on a trailer and from there the dredger simply walks into the pool by itself. In the pool Watermaster moves with its own propulsion system and can also move to another pool by using its excavator assembly and spuds. It can pump the mass into another pool up to 1,5 kilometres away. By backhoe work it can build and repair the pool banks.

    Watermaster can also recover valuable materials from tailings ponds and drainage ponds.

    Water treatment solutions for the mining & metallurgy industry

    Contaminated mine water is generated when rock containing sulphidic minerals is exposed to water and oxygen, resulting in the production of acidity and high concentrations of metals and sulphate in the water. Mine drainage, process water and storm water associated with industrial activities are the main types of water produced in mining operation. The two primary aims of the treatment of contaminated mine water are to neutralize acidity and removal metals. Lenntech provides sustainable complete water treatment solutions for mining industry considering a wide range of technologies and strategies.

    Environmental solutions for the geomembrane protection

    High-Strength Protection of Geomembrane Liners. As a protective cover for geomembranes for closure caps and stormwater ponds, the GEOWEB system prevents liner damage and degradation. With infill confined in the GEOWEB system, slopes can be designed steeper while maintaining strength and integrity, even when subjected to settlement - common in landfills.  The landfill cover system can be designed as a vegetated, aggregate armored, or concrete solution that remains flexible.  GEOWEB liner protection is a ‘complete solution’ including integral tendons and ATRA tendon load transfer clips.

  • Tunnels

    The geotextile performs two primary functions when used in the construction of tunnels:- 1. Protection of the linear from abrasion and puncture by protrusions from the base surface of the tunnel well. 2.Drainage of water seeping through the rock and sprayed concrete layer. The in-plane oermeability of the geotextile enables the water to flow to a subsurface drainage collection system. where it is directed awa from the tunne

  • Water Monitoring and Flow Measurement Systems for Hydrology

    In recent years acoustic flow measurement and flow metering has established itself as the standard method for measurement in many hydrological stations but is also used as the basis for various applications, for example for flood protection and flood forecasting. Ultrasonic flow meters are also used in hydro-engineering constructions. With this almost contact free technology data can be recorded continuously and it provides 24/7 monitoring. Such flow monitoring is particularly important in waterways used for shipping, transportation, irrigation, drainage and for cooling water extraction of power plants. A further important use of transit-time open channel flow meters is the transportation of water used for the supply of drinking water. Here the focus lies on detecting the flow rate of water loss at an early stage as it is sometimes difficult to detect small leakages.

  • Soil Stabilization

    Problem: Poor load-bearing soils pose a significant problem for transportation and construction needs. Unpaved areas, such as access roads, paths, parking lots, driveways, etc can be highly vulnerable to near-surface shear failure and rutting, especially in moist conditions or areas with higher expected loads. Typically, engineers bridge over weak soils with rigid structures such as thick, reinforced concrete for roads and highways. However, such techniques are prohibitively expensive and inordinately difficult to install. The poorer the quality of the sub-base and the heavier the expected loads, the greater the amount and better the quality of support required.

  • Contaminated Water Filtration

    Industry standard best practices are designed to ensure that all work done on Asbestos Abatement Projects is done to the highest level of safety and risk management. Containment of the generated waste water fibers and debris is critical to proper compliance and worker safety. If these fibers are not captured and contained, they can be very harmful for the environment, on-site workers and the occupants of neighboring areas. Exactly how you approach your containment and capture solutions will depend on the individual site’s risk assessment report. If you need help identifying solutions to the issues raised in the report, feel free to contact our customer service department and we can review your options together. Water from showers at Asbestos Abatement sites is often contaminated with asbestos fibers from washing protective gear and equipment. This water must be filtered prior to discharge into a drain.

  • PEHD membrane sealing systems for retrofitting in existing landfill site

    It is also possible to retrofit a monitoring system in existing surface sealing liners without impairing the synthetic liner sheet or the immediately adjacent functional layers. For this purpose, cable trenches must be dug in the recultivation layer above the drainage layer. The detection cables are then laid in these trenches.

  • Separation and filtration for urban areas

    In urban areas can geotextiles be found in most diverse applications. The geotextiles are being used in access and paved roads, sport fields, riverbed protection, drainage trenches and pond liner protection. The geotextiles are also being used in vertical drainage applications. Groundwater and excess rainwater can be controlled well when geotextiles are properly used. More and more floods cause serious damage to urban areas.
