Moreover, gravel drainage is very resistant and does not wear down easily, so you won’t need to constantly spend time & money on its upkeep. That is why gravel rocks dry quickly after rain and are perfect for draining systems. READ: What are the Clouds, How Do They Form and Different Types of Cloudsĭrainage gravel also has heat absorption qualities it absorbs the sun’s rays during the daytime and radiates the stored heat out at night. Often quick-absorbing topsoil is responsible for waterlogging issues, and gravels can help solve this problem.
There are gravels especially designed for this purpose called drainage gravel, which divert water away and prevent pools of water from accumulating. Yes, because of its high hydraulic conductivity, gravel plays a key role in drainage systems. Improper water flow can also cut through the soil unpredictably, leaving furrows and spoiling the beauty of your garden. Moreover, these tiny pools serve as breeding grounds for mosquitos and bacteria. Unwanted water accumulation of any kind is harmful to gardens: it turns soil beds into swamps, drowns cultivated plants, and makes paths slippery. Yes, water flows much more easily through gravel than it does through other kinds of soil because its tiny rocks are not tightly packed and allow water to flow through them. Gravel is especially important in areas where people walk because they reduce the chances of slipping hazards by offering friction and draining water. Unlike soil surfaces, gravel pathways and borders do not allow puddles to form easily. This is why gardens often use gravel to divert water and mitigate water accumulation. Gravel has high hydraulic conductivity, meaning that it allows a fluid to move through its pore spaces or fractures quite easily. No, the tiny stones of gravel do not soak up water like soil or sand, but they do allow water to seep through them easily.
