Moisture retention refers to the ability of a material or environment to hold water. This property is important in various fields, including agriculture, gardening, and construction. In soil, moisture retention helps plants access water, promoting healthy growth. Different soil types have varying capacities for retaining moisture, with clay soils generally holding more water than sandy soils. In the context of building materials, moisture retention can affect the durability and comfort of structures. Materials like insulation and concrete can influence how much moisture is retained, impacting indoor air quality and energy efficiency. Proper moisture management is essential to prevent issues like mold growth and structural damage.
