adj.
Impossible to permeate: an impermeable membrane; an impermeable border.

impermeability im·per'me·a·bil'i·ty or im·per'me·a·ble·ness n.
impermeably im·per'me·a·bly adv.

Not allowing the passage of a fluid; in hydrology, the fluid is water. Impermeability in a rock may be due to an absence of pores, joints, or bedding planes, or because pores are so small that the water within them is ‘locked in’ by surface tension.

Said of a soil whose particles are so closely spaced that the passage of water is either prevented or very slow.
