A material can be porous but also impermeable due to its surface structure. The molecular level can allow molecules of air to pass through, but not water molecules.
many materials, such as GoreTex, has a surface structure, that at a molecular level can allow molecules of air to pass thru but not molecules of water. This way, you can be protected from falling rain, but also have a material that will "breathe" and wont keep you feeling muggy inside.

Is an aquitard porous or impermeable?
it has to be impermeable so it can line the aquifer without letting water straight through
Water cannot pass through solid rock because it is?
The rock is impermeable (not porous).
Does not let water pass through it?
Water cannot pass through tyvek. Water vapor can however but liquid water cannot. Tyvek is high-density polyethylene fiber and is a synthetic material.
What are permeable and impermeable rocks?
Permeability is a measure of how well a porous media transmits a fluid. It has nothing to do with the fluid itself. It is measure in (length)2. The Hydraulic Conductivity is a measure of how easily water moves through the porous media. It depends on the permeability of the matrix, but also is a function of the fluid. It is a measure of (length)/(time)
What is porous rock?
anything that is porous is capable of absorbing water
What is the opposite of porous in science?
impermeable or non-porous.
Is an aquitard porous or impermeable?

What is impermeable material?
Impermeable material is material that does not allow anything to penetrate it. An example of it is CLAY.
How can something be porous but also impermeable?
Believe it or not, some porous rocks are considered impermeable. No rock is completely impermeable, but some porous rocks like shale and pumice are mostly impermeable, because the pores are not interconnected, thus not allowing fluids or gases to pass through them. This is why shale makes a good cap-rock, and pumice floats instead of sinking.
What does non-porous mean?
Porous means 'with holes'. So non-porous means 'without holes'
Is granit a porous rock?
The crystals of granite are very tightly interlocked. This means that granite is not a very porous type of rock.
Water cannot pass through solid rock because it is?
The rock is impermeable (not porous).
Does not let water pass through it?
Water cannot pass through tyvek. Water vapor can however but liquid water cannot. Tyvek is high-density polyethylene fiber and is a synthetic material.
Is asbestos a porous material?
Asbestos is a porous material and can absorb water.
A material that will not let water through?
An impermeable material.
Is gravel a impermeable material?
yes
What material is not use as a sealant?
A material that is not used as a sealant is mesh. Mesh would be inappropriate to use since it does not prevent leaks and is porous. There are other materials, such as fabric, which are also porous.
