Lafarge's Regular Septic Sand is available at most of our pits through-out the Fraser Valley and Lower Mainland, but the Modified is only available at our Coquitlam Sand and Gravel Pit. We also produce a consistent gradation of natural washed 20-14mm Septic Stone (3/4x1/2") that meets local municipal standards.
Soil gradation - Wikipedia
Soil gradation is a classification of a coarse-grained soil that ranks the soil based on the different particle sizes contained in the soil. Soil gradation is an important aspect of soil mechanics and geotechnical engineering because it is an indicator of other engineering properties such as compressibility, shear strength, and hydraulic conductivity.
