Guide — Field Compaction & Density
The field compaction calculator below follows standard Indian construction practice and the relevant IS-code conventions. Enter the site dimensions exactly as measured, press Calculate Now, then refine the quantities line by line in the live sheet before you export.
Field dry density is the wet density divided by one plus the moisture content as a fraction. Comparing it with the laboratory maximum dry density from the modified Proctor test gives the degree of compaction.
Embankment layers are normally accepted at 95% of MDD and sub-grade at 97%; granular sub-base and WMM demand 98% or higher. Moisture at the time of rolling should be within ±2% of OMC.
Take at least one core-cutter or sand-replacement test per 500 m² per layer, and always test the layer edges — the outer metre of an embankment is where compaction failures concentrate.
Treat every output as an indicative pre-tender estimate. Site conditions, wastage allowances, specification changes and local market rates all move the final figure, so validate against your drawings and approved rate analysis before procurement.

About the Field Compaction & Density
This tool is built for site engineers, quantity surveyors, contractors and property investors who need dependable numbers fast. Every input is reactive — changing a single field instantly recomputes the full output set, so you can run sensitivity checks on dimensions, grades and rates before committing to an estimate.
Keep unit consistency in mind: metric inputs (metres, square metres, cubic metres) produce metric outputs, with imperial and Indian trade units shown alongside where they are commonly used on site.
