Construction sites face different challenges, and one of the most common issues/ challenges has to do with wet soil, soil that is too weak, or soil that’s too expansive to meet the structural requirements necessary for the support of buildings, roads, airport runways, parking lots, and all other load-bearing structures.
To counter these challenges and to come up with structurally sound constructions, you will need the best of soil stabilization solutions that match the needs of the site – the soil and the weather conditions. One of these soil stabilization solutions is called Calciment soil stabilization.
What is Calciment?
Calciment is the co-product produced from the lime calcining process. It is a uniquely blended product made of calcium oxide (CaO) and Pozzolans. The pozzolans give the product its cement-like properties, which allow for the use of Calciment as the soil stabilizing product for waste streams, problematic soils, and also sediments. The CaO in the Calciment will accelerate the dewatering/ drying process of the soil is wet and/or cold climates. Calciment has the unique chemistry seen in quicklime, and it’s also made with fly ash adds to the versatility of the Calciment, while also enhancing its drying, stabilization, and modifying effects. The fly ash serves as an additive.
Calciment soil stabilization is not only one of the most efficient and cost-effective solutions, but it’s also an effective all-year-round solution which will allow construction works to run with ease. Thanks to the soil Calciment, there are fewer project delays because of wet weather. The Calciment will also reduce the permeability of the soil, especially in heavy rain conditions, and it also protects the areas that have been treated.
Using Calciment as one of the best stabilizing soil solutions, you will get to enjoy significant savings of up to 75%, especially in the cut/ fill methods. You’d also save up to 80% when using Calciment compared to the use of traditional cement.
How is Calciment Used?
As one of the leading soil solutions for soil stabilization, its use is important. But you need to understand exactly how to use it.
Essentially, the Calciment would be mixed into the wet soil, where it will initiate an immediate reaction that causes drying. The drying happens because the calcium oxide in the mixture hydrates and absorbs/ eliminates the water from the soil.
So, if you are dealing with fine soil such as silt or clay, there will be a cation exchange as well as a flocculation reaction, which would result in the improvement of the soil’s workability, plasticity, and compaction. The compressive strength of the soil will also increase as a result.
As a result of these immediate reactions and effects, you will have an expedited construction process, especially if your site had plastic, soft, or non-cohesive soil, which wasn’t supportive of the vehicles used in construction. These effects also offer sub-grade support for different paving operations.
Note that the drying reaction of calcium oxide results in the cementing of the soil. These drying reactions are also called pozzolanic cementing reactions, which will not only consume water but encourage the production of soil with a higher unconfined tensile strength, compressive strength, shear strength, swell potential, as well as a reduced permeability.

Note that Calciment is a green solution, and it’s DOT-approved and also LEED-Certified.
