The 3D printing technology, also known as additive manufacturing, is a binder jetting process which involves selectively depositing a furan-based binder into a sand bed one thin layer at a time. Over the course of the process ...

Permeability Permeameter

Soil permeability tests analyze how quickly water moves through a soil sample. Water is introduced to the soil at a known pressure, and the flow is measured to determine how permeable the soil is. For the most part, sandy or rocky soil will be highly permeable, while soils with high quantities of clay will have much lower permeability.

Soil Permeability Testing Equipment - Karol-Warner

Soil permeability, sometimes called hydraulic conductivity, is a measure of water flow through interconnected voids in a soil matrix. In geotechnical design, this property allows accurate calculations in areas such as drainage, earthen dam design, and slope stability.
