Reformation of Factory Farming The global population as of July 2020 is 7.7 billion, according to the United States Census Bureau. And the United Nations has estimated that this number will grow to 10 billion by 2050. If the human population does continue to grow so rapidly, an increase in the amount of available food…
What is a Vapor Barrier Membrane for Soil Gas Mitigation? A vapor barrier, or a sub-slab vapor membrane, is a layer of protective material that prevents toxic vapor intrusion into buildings. An impervious vapor barrier can be a combination of plastic film, fabric, and sheets. And there are also roll-on and spray-on applications. Contractors usually install…
Licensed Professional Geologist A “Licensed Professional Geologist” or a “Certified Professional Geologist” is a person who is certified by a State and/or Federal agency (such as the California Department of Consumer Affairs, Board for Professional Engineers, Geologists & Land Surveyors), and has proven be educated, formally trained and professionally competent per government standards, to practice…
Consistency The term “Consistency” in the fields of engineering geology and geotechnical engineering means the degree of adhesion between soil particles within a sample, that are observed to resist deformation or rupture.
Consolidation “Consolidation” in geology refers to the gradual or slow reduction in the volume of a soil sample (representing a larger soil mass), and the increase in density in response to an applied increasing load, or compressive stress.
Critical Void Ratio The “Critical Void Ratio,” in soil science and geology, represents the final void ratio of a soil sample, at ultimate strength. And Critical Void Ratio is achieved by the loose and dense samples of the same soil post-shearing.
Degree of Saturation (SR) “Degree of Saturation” (SR) is an engineering geology term and refers to the ratio of the volume of water to the total volume of void space. The Degree of Saturation or SR-value ranges from 0% to 100% (0% being completely dry, and 100% being fully saturated). Degree of Saturation Formula Degree…
