Septic Stone

Septic Stone is a specialized, clean-crushed limestone aggregate meticulously washed and screened to a consistent size, typically ranging from 3/4" to 1-1/2". Unlike standard gravel mixes, septic stone contains absolutely no sand, dust, or "fines." This creates a high volume of interconnected void spaces that are essential for the biological and physical processes within a leaching bed. In Ontario, this product is manufactured to meet specific environmental and engineering standards, ensuring it provides a stable, non-compacting medium that allows effluent to distribute evenly and filter safely into the soil.
