Clay is a very good example of an impermeable material. Although, clay exhibits a lot of porosity, the permeablility rate is very poor. Clay materials are excellent aquacludes. They form aquifers and prevent the water in the aquifer from moving upward until the clay material is breached by drilling, seismic activity or other means that create a pathway for the water to move. Penetrating a clay layer usually causes artesian or flowing artesian conditions in the aquifer.
Highly impermeable layers such as compacted clay or shale are known as aquitards. Aquitards restrict the flow of water and are typically found between aquifers, acting as a barrier to the movement of groundwater.
Clay is permeable, meaning it allows liquids or gases to pass through it. It is not impermeable, which would prevent the passage of liquids or gases.
Impermeable layers typically include materials such as clay, shale, and waterproof membranes. These layers do not allow the movement of water or other fluids through them, providing barriers to prevent seepage or leakage. Layers that are impermeable are commonly used in construction for purposes such as waterproofing foundations or containment of liquids.
Water can travel underground through permeable rocks and soil, such as sandstone or gravel, but not through impermeable materials like solid rock or clay. Impermeable materials act as barriers that prevent water from passing through them.
Aquifers form above permeable soil, such as sand or gravel, that allows water to flow easily. Impermeable soils like clay or bedrock will prevent the formation of aquifers.
Impermeable material refers to substances that do not allow liquids or gases to pass through. These materials create a barrier that does not allow the transfer of substances like water or air. Examples of impermeable materials include plastic sheeting, rubber, and metals like steel.
Granite, Clay.
Impermeable means water can't get through it. For example, clay is impermeable substance (because water can't seep through it), but chalk is permeable (because water can drip through it slowly) Sometimes it also applies to places which you can't get into, for example, an 'impermeable fortress' would be difficult to get into.
An aquiclude is a layer of impermeable rock or material that prevents the flow of water. An example sentence would be: "The clay layer acts as an aquiclude, preventing water from passing through."

An impermeable material.
Impermeable material does not allow water to pass through easily. This can include substances like clay, solid rock, or plastic sheeting, which have very low rates of water permeability.
An impermeable material would have small pores, if any, that are likely unconnected. Small pores limit the movement of substances through the material, and unconnected pores minimize the pathways for substances to traverse.

It is an impermeable material.
Compacted clay soil is fairly impermeable to leaching.
