Free Dirt Shrinkage Calculator
Did you ever wonder how they calculate shrinkage for dirt? Well, here it is. Plain & Simple
Enter the Max density and the compaction required, then go through the borings and put in the in situ densities for the depth you are working.
The program returns the general shrinkage or bulk value for each boring and the average for the project.
You can print the result or download it as a CSV.
