Soil Erosion
Dust Suppression
Erosion, whether it is by water, wind or tillage, involves three distinct actions – soil detachment, movement and deposition. Topsoil, which is high in organic matter, fertility and soil life, is relocated elsewhere "on-site" where it builds up over time or is carried "off-site" where it fills in drainage channels. Soil erosion reduces cropland productivity and contributes to the pollution of adjacent watercourses, wetlands and lakes.Soil erosion can be a slow process that continues relatively unnoticed or can occur at an alarming rate, causing serious loss of topsoil.Soil compaction, low organic matter, loss of soil structure, poor internal drainage, salinisation and soil acidity problems are other serious soil degradation conditions that can accelerate
the soil erosion process.Wind erosion of soils is one of the most important problems in environment and agriculture which could affects several fields. Agricultural lands, water reservoirs, irrigation canals, drains and etc. may be affected by wind erosion and suspended particles. As a result wind erosion control needs attention in arid and semi-arid regions.
We at TRANS-L-GEOTECH use latest technology of using geogrids and chemical soil stabilizers to arrest soil erosion and keep the moisture of the ground for longer period of time for vegetation to grow and keep environment free from dust pollution.
Visible Dust Emissions (VDE) may not exceed 20% opacity during periods when soil is being disturbed by equipment or by wind at any time. Visible Dust Emissions opacity of 20% means dust that would obstruct an observer’s view of an object by 20%. Dust control may be achieved by applying water before/during earthwork and onto unpaved traffic areas, phasing work to limit dust, and setting up wind fences to limit windblown dust. Soil Stabilization is required at regulated construction sites after normal working hours and on weekends and holidays. This requirement also applies to inactive construction areas such as phased projects where disturbed land is left unattended. Applying water to form a visible crust on the soil and restricting
vehicle access are often effective for short term stabilization of disturbed surface areas. Long-term methods including applying dust suppressants and establishing vegetative cover.
Fugitive dust is generated along unpaved mine roads from intermittent equipment traffic. Typically, the majority of such traffic consists of trucks hauling either mine product or waste from the surface mine pit and/or the processing plant. Fugitive dust generated along these unpaved mine roads includes particles of all sizes that become airborne. The potential hazards include the deleterious effects to human health of inhaled dust, traffic visibility hazards, and environmental impacts.
We at TRANS-L-GEOTECH use latest geotechnology by using chemical soil stabilizers to control the dust emission from unpaved Haul Roads for a longer period of time. This also eliminates frequent water spraying to save water and improve sight for the trucks, resulting in smooth traffic to increase productivity.
Soil stabilization is a major factor effecting the cost of constructing a road where the sub-grade can consist of native in-situ soil or rock, previously placed landfill or mine spoil, muskeg, marsh or other existing surface over which a road is to be placed. Where the sub-grade comprises hard, sound rock or dense, compact gravel, little or no fill may be necessary as haul trucks can travel on the sub-grade surface. Sub-base is the layer of a haul road between sub-grade and base course of the road. It usually consists of compacted granular material, either cemented or untreated. Run of mine and course rocks are the general components of this layer. Apart from providing structural strength to the road, it serves many other purposes such as preventing intrusion of sub-grade soil into the base
course and vice-versa, minimizing effect of frost, accumulation of water in the road structure, and providing working platform for the construction equipment.

We at TRANS-L-GEOTECH use latest technology in the form of chemical soil stabilizers which reduces road construction costs by 20%to50% as an economical alternative to concrete slurry and quarried rock aggregate. This considerable cost savings is possible as the insitu soil(onsite) is used as the aggregate to create durable roads, circumventing the need for expensive excavation and importation of high-cost quarried construction aggregates.
