drainage material Applications

  • 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

  • Dewatering trenches

    Our articles are designed to allow liquids to pass in the draining systems as in the micro pore tubes and at the same time help to retain the finer particles while avoiding their migration into the drainage.

  • Groundwater Monitoring for Construction Sites

    All construction affects groundwater and a water management plan will be required. From deforestation to urbanisation, from holes to heaps and dams to drains, they all have an affect on the groundwater. Deforestation causes an increase in the rate of run off of rainwater resulting in lower percolation of precipitation into the soil and a consequent increase in soil erosion leading to slope instability, hence land and mud slides. The increased rate of run off can cause small streams and large rivers to rise and flood in a shorter time, but also to dry up sooner. These conditions cause great difficulties for subsistence farmers in developing countries. Urbanisation also causes faster run off because of the non permeable surfaces such as roads, roofs and car parks. This also creates drainage problems that can lead to contamination and erosion of natural water courses.

  • 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.

  • Geosynthetic Lining for Highway and Civil Applications

    GCL can be used in highway and civil applications such as at airport de-icing facilities used to remove ice build up on the surfaces of planes. During the application process, glycol-based de-icing fluids can leak into local stormwater runoff, potentially causing pollution. CETCO GCLs were found compatible with de-icing fluid (glycol diluted 50/50 with water). GCLs can also be used to line roadway drainage swales for containment and prevent excessive percolation, thereby minimizing potential for groundwater contamination. Another example of using GCL in civil and highway applications is using the liner to contain acid rock and prevent runoff from entering the local water supply.

    Jaw bucket crushers for urban job site and road works

    MB`s range allows for the crushing, recycling and reusing of materials to create roadbeds, drainage beds and dig fills directly at the worksite, thus reducing the cost of material transportation. Characterised by reduced dimensions and weight, MB also proves to be the ideal choice for small urban sites, or when special attention to the surrounding environment or architecture is necessary. With MB to work in historical urban centres and important sites is no longer a problem, and it can offer a new source of income for building companies.

    Geotextiles solutions for tunnel construction areas

    Quicker, easier, safer transportation means are required.  Depending on geographical zones, tunnels can be a must to reach your final destination easily. Decades of experience in tunnel constructions with TenCate Polyfelt P have shown that protection geotextiles replaces the need for drainage material around the tunnel lining.

    Water treatment chemicals solutions for pulp and paper industry

    In the manufacturing of pulp, the raw material for paper, problems such as the piercing and ripping of paper occur due to calcium carbonate and other scales and pitch deposits (adhesives contained in wood and old paper). To prevent these problems, Kurita Water Industries offers a range of water treatment chemicals such as anti-scale agents and pitch control agents. For the paper-forming process that produces paper from pulp, we offer water treatment chemicals such as slime control agents that help improve the paper quality by removing the bacteria and fungi in the water that dissolved pulp. We also provide yield and drainage improvers that help improve production efficiency by making drainage better.

    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.

  • Erosion & sediment control solutions for costal/beach region

    Coastal erosion is the wearing away of land or the removal of beach or dune sediments by wave action, tidal currents, wave currents, or drainage. Removing sand and other materials from beaches and dunes due to tidal storm surges and construction purposes causes massive beach erosion damages and land loss of seashores, thus destroying the natural heritage of the coast and reducing the vibrancy of the tourism industry. Uprooting vegetation from coastal areas destabilises beaches and clearing sites inland results in increased soil and dirt particles being washed offshore and smothering coral reef systems.
