When it is exposed to water, it chemically hydrates resulting in a gel that forms an interlocking matrix around particles. Most importantly is it's ability to absorb noise and deter the spread of fire. Assuming fixed compaction effort, the only variable the contractor can control is What is an Expansive (Shrink-Swell) Soil? "Dry-up" of wet soil at construction sites is one of the widest uses of lime for soil treatment. This reduces the chances of trapped moisture and the damage of the building. SInce it is not a conventional building material, the contractor or do-it-yourselfer will need to learn new construction techniques. Hydrated lime can still supply the calcium that is essential to stabilize certain soils by forming cementitious bonds. The costs associated with delivering material is dependent on the distance from the material production plant to the job site and trucking rates by location. Cement vs. After 5 days, the third coat called the finishing coat is applied over the second coat, the thickness of the third should not exceed 3mm.
