Because the molecular lattice is tighter and smaller than waters molecular lattice making it impermeable

The molten liquefied rock is called lava when it erupts from a volcano or fissure and cools into a porous black and hard material known as basalt or igneous rock.
When molten magma cools and crystallizes, it becomes a hard rock called igneous rock. Different magmas have different compositions and so produce different igneous rocks. If the magma cools beneath the earth's surface, it cools slowly. Rocks formed like this are called intrusive rocks, and have large crystals, e.g. granite, gabbro, dolerite. If magma comes to the surface (in a volcanic eruption) it cools rapidly. Rocks formed like this are called extrusive rocks, and they have small crystals, e.g. basalt, obsidian, pumice. Igneous rocks have interlocking mineral crystals. The crystals are arranged randomly throughout the rock. Igneous rocks are mostly non-porous.
The hard mineral that makes up your skeleton is primarily calcium phosphate, in the form of hydroxyapatite crystals. These crystals provide strength and rigidity to bones, contributing to their structural integrity and ability to support the body.
Hard non-porous surfaces are materials that do not allow liquids or gases to pass through them. Examples include glass, metal, plastic, and sealed wood. These surfaces are often easy to clean and disinfect because they do not absorb contaminants.

granite is a hard rockk madeof crystals
Medium.Not hard or easy.
Two types of non-porous rocks are quartzite and marble. Quartzite is a hard, non-foliated rock composed of quartz grains, while marble is a metamorphic rock primarily made up of calcite or dolomite crystals. Both rocks have low porosity, meaning they do not absorb water easily.
They are not rare nor are they hard to find .
I think it is because metals are non-porous, with more dense and compacted molecules compared with water, wood or other porous materials.

when bituminous coal is heated stronly in the absence of air,the volatile matter escapes out and the mass becomes hard,strong,porous and coherent which is called Metallurgical coke.
A cap rock is formed when a hard, impermeable layer of rock, such as shale or limestone, is deposited on top of softer, more porous rock layers. Over time, the cap rock protects the underlying layers from erosion, creating a natural barrier that can trap resources like oil and gas beneath it.
