Artificial turf – also known as synthetic grass, fake grass, or astro turf – is becoming an increasingly popular alternative to natural grass for lawns, sports fields, and playgrounds. It has many advantages, such as conserving water, reducing maintenance costs, and providing a year-round green space for people to enjoy. One question that often comes up when installing artificial turf is whether it is necessary to put anything underneath it. In this article, we will explore this topic and provide some insights on what to consider when installing artificial turf.
The short answer is yes, you should put something under artificial turf carpet to help stabilize and cushion it. The most common materials used as a base layer for artificial turf are gravel, sand, and crushed stone. These materials provide a stable and level surface for the turf to sit on, prevent weeds from growing through the turf, and allow for proper drainage. Depending on the specific requirements of your project, you may also need to add other layers, such as a geotextile fabric to prevent soil mixing, a shock-absorbing pad for sports fields, or a layer of decomposed granite for enhanced drainage.
One of the main reasons for putting a base layer underneath evergreen artificial turf is to provide a stable and level surface. Unlike natural grass, which can adapt to slight variations in the ground surface, artificial turf requires a more precise level of grading and compaction to avoid bumps, dips, or uneven areas. Gravel, sand, or crushed stone are commonly used for this purpose, as they are easy to spread, compact, and level. These materials also create a solid foundation for the turf to sit on, which helps to prevent shifting, wrinkling, or buckling that can occur over time.
Another reason to put a base layer under artificial grass turf is to prevent weeds and other plants from growing through the turf. Although artificial turf is designed to resist weeds and requires little to no maintenance, it is not completely immune to plant growth. If there are weeds or grass already growing in the soil, they may penetrate the turf and cause damage over time. By laying down a layer of gravel, sand, or crushed stone, you can create a barrier that inhibits the growth of weeds and other unwanted plants. This will not only help your artificial turf look better but also reduce the need for herbicides and other chemicals.
Proper drainage is essential for soccer artificial turf, as it can become waterlogged and muddy if water is not allowed to drain properly. By placing a layer of porous material, such as gravel or sand, under the turf, you can create a space for water to flow through and drain away. This will prevent puddles from forming, reduce the risk of slip and fall accidents, and improve the durability and lifespan of your artificial turf. Depending on the site conditions and local drainage requirements, you may need to add additional drainage layers, such as a perforated pipe or a layer of gravel to enhance water flow.
In addition to these benefits, putting something under artificial turf grass can also help to enhance its overall performance and comfort. For sports fields or playgrounds, a shock-absorbing pad or cushioned layer can help reduce the risk of injuries and provide a soft landing surface for players or children. For commercial or high-traffic areas, a layer of decomposed granite or other crushed stone can add an extra level of durability and abrasion resistance, which helps to extend the life of the turf.
In conclusion, while it is possible to install artificial turf directly on top of the soil or existing grass, it is generally recommended to put something underneath it to provide a stable, level, and well-draining base. Materials such as gravel, sand, or crushed stone can help create a solid foundation, inhibit weed growth, and enhance drainage. Depending on your specific needs and requirements, you may also need to include other layers, such as a geotextile fabric, a shock-absorbing pad, or a layer of decomposed granite. By taking the time to properly install your artificial turf, you can ensure that it looks and performs great for years to come.
