Measurement & Testing: Precision in Every Load

At Aggtrans, we don’t just sell soil—we ensure that it’s the right soil for your project. Every product undergoes testing for key parameters such as sand, silt, clay content, and nutrient levels to meet regulatory standards. We also provide conversion yield factors for all soil mixes, which help with accurate volume-to-weight conversions. This is essential for precise material estimation and cost calculation, so you can plan your project effectively.

Why tonnage matters
Tonnage is the most accurate and consistent measurement

Tonnage vs. Cubic Yards: Why It Matters

In the construction industry, materials like soil are often measured in cubic yards. However, at Aggtrans, we firmly believe that tonnage is the most accurate and consistent measurement. Here’s why:

🎯 Moisture and Density Variations:
Soil weight can vary greatly depending on moisture content, soil type, and compaction. For example, dry, loose soil weighs less than wet, compacted soil. Relying on cubic yards alone can lead to inaccurate estimates, impacting your project’s budget and timeline.

🎯 Precise Measurements with Tonnage:
We measure all our materials by ton because it gives a precise, consistent measurement that ensures the correct amount of soil is delivered to your site. Our scale is calibrated to provide accurate weight, not estimated volume.

🎯 Accurate for Critical Projects:
When soil is measured by ton, it eliminates the uncertainties that moisture content or density might introduce. This precision is crucial for projects like foundation work, landscaping, and construction, where the exact amount of material is vital to the project's success.

PLEASE NOTE: Testing results are only applicable to the material at the time of production. Once the material leaves Aggtrans' custody, we are no longer responsible for any changes in the testing results. Environmental conditions, weather, job site factors, or other variables can affect the material after it leaves our premises, and it is the responsibility of the purchaser to ensure that the material meets their requirements upon delivery or at the job site. The manufacturer/supplier is not responsible for conversion factors related to settled or compacted material, job site conditions, stockpiling, or weather conditions. The contractor's estimating team is responsible for determining the appropriate conversion factor based on the required installation method.
