The 1-11-11 Rule
In the aggregate industry, moisture content can dramatically affect your inventory calculations. The 1-11-11 Rule states that for every 1% increase in moisture content, you can see up to 11% variance in weight measurements.
Texas Humidity Impact
In the DFW area, humidity levels fluctuate significantly throughout the year. Summer months can see moisture content in stockpiles increase by 3-5%, potentially creating 30-50% variance in weight-based inventory estimates.
Why This Matters
If you're relying on belt scale weights or truck counts, you may be paying for water, not aggregate. Volumetric measurement via drone survey eliminates moisture as a variable entirely.
