I DON'T have to travel all the way to Gua Tempurung to see stalagmites and stalactites. They can be easily seen in the car park of my condominium, more specifically, the car park area below the swimming pool.
The stalagmites, which hang from the ceiling, and stalactites, which grow up from the ground, is chemically known as calcite or hydrate of calcium carbonate.
It is formed through the reaction between water and calcium carbonate. In other words, for calcite to be formed, calcium carbonate and water must be present.
Based on the above information, I assume that water from the swimming pool has seeped into the cracked area of its concrete.
I am concerned about this symptom because I cannot discount the possibility of the formation of calcite that leads to cracks, breakage of wall surface, and corrosion that will affect the integrity of the building.
I hope the authorities will take action.
