Check your inputs

The correct lime percentage for your soil must be determined by a geotechnical lab mix-design study (e.g. per ASTM D6276) — this calculator only converts a known target percentage into a material quantity, it does not determine the required percentage itself.

At the values currently entered, the lime needed works out to 6400 kg. Note that soil volume to stabilize (m³) sits at the low end of the range this calculator was checked against, so treat the output as indicative rather than settled. Confidence is moderate: the method is sound, but real materials and site conditions vary. Figures are shown for United States, where IRC 2024 is the governing residential reference; switch the market above if you are building elsewhere.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

  • Lime mass = soil volume × soil dry density × target lime content percentage (by dry weight), the standard method for proportioning lime in lime-soil stabilization

Frequently asked questions

Why is lime content expressed as a percentage of soil dry weight?
Lime-soil stabilization design is based on the ratio of lime to the dry mass of soil being treated, so this calculator converts your soil volume to a mass (via dry density) before applying the target percentage — that keeps the lime dosage correct regardless of the volume measured on-site.
How do I determine the right lime percentage for my soil?
The correct target lime content must be determined by a geotechnical lab mix-design study on your specific soil (e.g. per ASTM D6276). This calculator only converts a known target percentage into a material quantity — it does not determine the required percentage itself.
Why does soil dry density matter to the result?
Soil dry density is a measured property of the specific soil being stabilized, not a fixed constant. A denser soil has more mass per unit volume, so it requires proportionally more lime mass to reach the same target percentage by dry weight.
