Permazyme can be used effectively over a wide range of soil gradation mixes (aggregate sizes), as can be seen from the above graph.

To achieve effective stabilization, materials containing approximately 20% cohesive fines (non-granular) have been found a satisfactory target. However, excellent results have been achieved outside this range.

Additionally, the soil should contain a wide range of material sizes to provide shear strength and internal friction which increases load bearing values.

Permazyme has proven useful over a wide range of soil types. This range continues to expand as Permazyme is used in more diverse locations throughout the world.
