Soil stabilization is a way of transforming a weak soil’s physical properties to boost its strength and reduce permeability. Stabilization can improve the load-bearing capability of a sub-grade to sustain pavement and its foundations by increasing the shear strength of the soil and controlling its shrink-swell qualities. Mixing additives into the reaction mechanism, positively affecting its strength, improving and maintaining the soil moisture content, achieve stabilization. Therefore, these soil stabilization processes are suggested for most construction projects like roadways, overpasses, residential and commercial buildings, parking lots, and airport runways.
Some of the top benefits of using soil stabilizers are:
Stabilizing the soil can help save a considerable amount of money compared to the traditional ‘dig and dump’ method, which incurs the high costs of landfill tax, trucking soil to the landfill and buying the aggregates.
Soil stabilizers can be designed to be more durable than the conventional granular sub-base. Using these materials in pavements or foundations means significantly improved strength.
Save the Environment
Compared to the dig and dump method, which would mean several truckloads of soil to be carried out and multiple truckloads of aggregates carried in, just a small load of the soil stabilizer can eliminate these vehicular movements and significantly reduce the environmental impact.
There is no need to import new materials as the in situ soil can be used after a simple treatment process. A Type 1 subbase is unnecessary as similar strength and properties can be achieved using soil in situ. By reducing the importation of the aggregates, the resulting wastage of soil is also avoided.
At ECMAS, we offer a GREEN soil stabilization product, ECMASTAB-99, a natural soil stabilizer prepared using polypropylene fibres and other environmentally-compatible materials.
ECMASTAB 99 has negligible environmental impact compared to conventional consolidation using concrete composed of inert matter and cement or lime and sometimes involving paving with a layer of asphalt. Adding ECMASTAB 99 to the soil alone is sufficient to ensure compactness and durability of the gravel roads without altering their colour or the ecological qualities of the “soil system” at a lower cost than conventional solutions (concrete – asphalt paving).
