What is soil modification?
Elastic clays cause billions of dollars of damage throughout the country every year. Soil modification changes undesirable characteristics in soils, like excessive elasticity, fat clay, and elastic silt. Treating unstable soils with the appropriate admixture can reduce your soil's destructive shrink/swell potential, simplifying paving and providing a stronger, longer-lasting roadway or structure.
What is moisture conditioning?
Moisture conditioning turns wet, unsuitable soils into usable dry fill by treating them with certain admixtures. Instead of paying for excavating and removing unusable soil, moisture conditioning lets you leave it in place and avoid exporting it. During winter, moisture conditioning is an inexpensive way to improve construction durability and provide protection from the elements. A Cem-Base expert can help you determine when this process suits your soil conditions and create an ideal admixture for your specific soil challenges.

Soil modification is a process that involves altering the physical and chemical properties of soil to improve its engineering characteristics and suitability for specific purposes. The goal of soil modification is to enhance the soil's strength, stability, compaction, and other properties relevant to construction. Various amendments can be added to the soil to modify its properties. Common amendments include quicklime, Portland cement, and various chemical additives. These amendments can improve soil structure, increase strength, reduce plasticity, and promote compaction.
Moisture conditioning plays a crucial role in soil workability and compaction. Adding water to dry soil increases its moisture content, making it more pliable and easier to work with. This allows for better compaction, ensuring that the soil particles are densely packed, reducing air voids, and increasing the soil's strength and stability. Moisture conditioning can aid in the consolidation of loose or loose-fill soils. By applying controlled amounts of water and allowing time for the soil to absorb the moisture, the soil particles can settle and reorganize, resulting in increased density and improved load-bearing capacity.
Conversely if your soils are too wet then quicklime can be added to the soil to bring it to its optimum moisture content and achieve maximum compaction.
It is important to note that the optimal moisture content for soil conditioning varies depending on the specific soil type, project requirements, and application. Soil moisture testing, such as the use of moisture meters or laboratory tests, is often conducted to determine the ideal moisture range for a given purpose. Consulting with Cem-Base soil scientists and engineers can provide guidance on proper moisture conditioning techniques and optimal moisture levels for specific soil applications.
The timing for building on modified soil can vary. Generally, stabilization requires curing time for the stabilizing agents to react with the soil and achieve the desired strength. The curing period can range from a few days to one week, depending on the specific materials and conditions. However if the soils are being simply dried back to their optimum moisture content using quicklime they will be ready immediately following treatment. It is crucial to follow the recommendations provided by soil stabilization experts or engineers regarding the appropriate waiting period before construction activities. The timing for construction can be determined based on the results of compaction and stability tests and the recommendations of Cem-Base's soil stabilization experts.
