Soil and Earthwork Calculator

Soil and Earthwork Calculator contains 60 Calculators for Soil Mechanics, Earthwork, Excavation, Compaction, Footing, Thrust from Soil, Explosion Calculations and Civil Engineering parameters.

Available for iPad & iPhone
Available in Imperial (USCS) and Metric Units (SI UNITS)
Auto-fill Reference Values — select a Soil Type or Surface Material from the built-in picker and all input fields populate instantly with standard engineering reference values
Built-in Reference Tables across 5 categories — Soil Properties (19 soil types), Atterberg Limits (15 classifications), Earthwork Materials (18 materials), Equipment Data (9 surface types + 5 scraper models), Water Conditions
Smart Pass / Fail Banners — Relative Density, Percentage Compaction and California Bearing Ratio display instant colour-coded classification results (e.g. DENSE, PASS, GOOD / EXCELLENT) after calculation
