Homeowners often overlook yard drainage until a problem occurs. The path of least resistance is the one that leads to the lowest elevations. Problems can arise when the original pathways are inadequate or blocked. This link: https://construction-update.co.uk/2021/02/16/14-reasons-why-land-drainage-is-important-easymerchant1/ gives you more information why you need to add drainage on your home.
The Effects of Drainage
Lack of drainage or slopes to divert water away from a property can cause it to flow into undesirable places, such as basements, foundations, and under sidewalks. Cracked foundations and flooded basements are alarming signs that something is wrong. However, addressing the problem can save you thousands of dollars and headaches. Groundwater and surface water are the two types of water that feed lawns. Groundwater is the water that lies beneath the top layer of soil. Because of the impermeability of the ground, it cannot penetrate further. This layer, also called the water table, is a layer of water that all soils have. Its depth varies depending on its location.
Rainwater can only flow along roads, driveways, and parking lots. Like grass, water can accumulate in depressions and flow into the ground at the edges. It leads to saturation in another area. If the soil is 100% saturated and it is little, or no drainage, excess water can accumulate in puddles. In addition, the soil takes longer to dry out. Both surface and subsurface drainage are essential protective measures for lawns and buildings. Surface drainage is the natural path that water follows after rainfall or irrigation. Subsurface drainage refers to drains or pipes that are installed in the yard. These drains remove water from the soil that has accumulated underground.
The Benefits
An integral drainage system protects your building from water damage by preventing water from contacting the concrete. Water that doesn’t evaporate or get absorbed by the soil ends up going somewhere. Often, this water will settle under and around your foundation. Drainage solutions can keep the moisture content of your foundation stable and even. It prevents expansion and contraction. It helps prevent cracks in the foundation caused by water infiltration. For the root system of grass and plants to be healthy, the soil must have adequate moisture.
You can remove excess water in the soil to increase the root zone and air. Increased airflow makes more nutrients available. Many of these nutrients need oxygen to be chemically transformed before plants absorb them. The soil is held in place by the root system that grows deep. It protects it from erosion. It also maintains the aesthetics of your property by preventing water from pooling on the surface. Recreational areas, such as parks, golf courses, and sports fields, can become more accessible and usable if traffic increases. Drainage helps nature remove excess water and allows the grass to recover quickly from rainfall. It will enable the recreation area to be open longer and used more often, increasing rev.
