Forty plus Years of Testing Soil
Laboratory Compaction
Both ASTM D698 and D1557 are available. Both Methods Utilize the Moist Method of Sample Preparation for Faster Turn-around Times.
Wet Sample Preparation
Wet Sample Preparation for the Atterberg (LL), (PL) and Hydrometer Analysis is extremely important especially when every number counts.
Liquid Limits
CQA Testing Laboratory Utilizes Both the Double-single point and Multi-point Methods When Determining the Liquid Limits of Soils.
Hydraulic Conductivity - Permeability
Turn Around Time
We understand that Turn around time is highly important. That is why we have 30 Saturation, Consolidation and Permeation Stations. We also utilize the Constant Volume method of measuring flow rates. We currently utilize 6 Constant Volume Manometers, making it conceivable to empty our Cells every 24 hours for another run of Specimens.
Additionally, all permeability specimens are Hand Calculated while preceding with Testing for those Client who need to know ASAP! Our Permeability Cells are configured to accommodate 1.4, 2.0, 2.1, 2.8 and 4.0" Specimens. Our Constant Head Cells, depending particle size, include 2.5, 4.5, 6.0 and 12" capability with a maximum 2" particle size. Report preparations are Computer Generated Reports that are Document Ready.
