The characteristic of certain ground covers to retain moisture above their surface stems from a combination of material properties and environmental factors. This phenomenon can manifest as visible pooling or a consistently damp feel to the touch, even after periods without rainfall. Examples include situations where puddles form on the fabric after irrigation or prolonged dampness persists beneath potted plants placed upon it.
The propensity for a ground covering to trap moisture is significant due to its influence on soil health, plant well-being, and overall weed control effectiveness. Historically, ground covers were selected primarily for weed suppression. However, an understanding of their impact on water management has grown, leading to considerations of permeability and drainage capacity when choosing materials.
