Chemoxy offers effective soil stabilisation chemicals. Find out more below.
Soil stabilisation is a way of improving the load bearing capabilities and performance of in-situ sub-soils, sands, and other waste materials in order to strengthen building land, road surfaces etc.
There are currently many techniques for soil stabilisation in today’s market, including compaction, dewatering and by adding chemical material to the soil.
Soil stabilisation has become one of the useful solutions to treat the soft soils to achieve the required engineering properties and specification so that structures can be placed safely without undergoing large settlements.
The sand is effectively “glued” together by the grouting mixture.
In certain regions of the world, typically developing countries and now more frequently in developed countries, soil stabilisation is being used to construct entire roads on weak soil structures.
The prime objective of soil stabilisation is to improve on-site materials to create a solid and strong sub-base and base courses. In certain regions of the world, soil stabilisation is being used to construct entire roads.
In the past, soil stabilisation was achieved by utilising the binding properties of clay soils, cement-based products, and/or utilising the “rammed earth” technique and lime.
As technology has evolved, there have now emerged new types of soil stabilisation techniques, many of which are classified as “green technologies”.
The picture below shows a weakened surface, due to subsurface voids, poor compaction and water pockets (left hand side) and the effect after adding the chemical grout filling the voids, compacting the weak spots and reacting with the Estasol® to promote the formation of the silicate gelation to support the surface.
Thus through reaction of silicates with the Estasol® (hardening system), the soil is reinforced and stabilised to afford a soil which has similar strength, structure and decreased permeability such that it behaves analogously to natural sandstone.
Typical application levels of Estasol® are ~3%/m³ of soil to be stabilised (loadings vary depending upon geological composition and structure of the soil).
Estasol® can be formulated into liquid hardeners for soil stabilisation and soil grouting. Through a reaction with the hardening system, a firm medium is formed analogous to natural sandstone. The advantage of using Estasol® as hardener is that it easily penetrates most soil types.
