Is wood impermeable?

Wood is porous, so it absorbs water and, when it does, the wood expands and warps causing structural problems. While no wood is completely waterproof, a few species of wood resist water better than others, and some paints and sealers make wood waterproof.

Why is clay impermeable water? Clay textured soils have small pore spaces that cause water to drain slowly through the soil. Clay soils are known to have low permeability, which results in low infiltration rates and poor drainage. As more water fills the pore space, the air is pushed out.

Is cell wall dead?
