Several components typically go under artificial turf to ensure proper installation and optimal performance. These layers serve various functions, such as drainage, stability, cushioning, and protection. The specific layers and their order may vary depending on the project and intended use, but here are the primary components that commonly go under artificial turf:
- Subgrade:
- The subgrade is the existing soil or ground surface where the artificial turf will be installed. It must be properly graded and compacted to create a stable and level base.
- Base Material:
- Above the subgrade, a base material is usually added to further level the surface and provide drainage. Common base materials include crushed stone, decomposed granite, or an aggregate base.
- Geotextile Fabric:
- A geotextile fabric is often placed over the base material to prevent weed growth and provide separation between the base and artificial turf.
- Drainage Layer:
- Drainage is crucial to prevent water from pooling on the surface. This typically involves the installation of a permeable aggregate layer that allows water to drain through it efficiently. The design should ensure proper water flow away from the area.
- Shock Pad or Underlayment:
- In some installations, especially for sports fields or play areas, a shock pad or cushioning underlayment may be used to provide extra support and shock absorption. This can enhance safety and comfort.
- Artificial Turf Carpet:
- The artificial turf itself is laid on top of the base layers. This is the visible surface that provides the look and functionality of natural grass.
- Seaming Tape and Glue:
- To join the sections of artificial turf together, seaming tape and adhesive glue are used. Proper seams are essential for a seamless and durable installation.
- Infill Material:
- Infill materials like sand, rubber, or a combination of both may be added to the artificial grass fibers. Infill enhances stability, maintains the shape of the turf, and helps with drainage. It can also provide additional cushioning.
- Edging Material:
- Edging materials, such as bender boards or landscape timbers, are used to create a border and secure the edges of the artificial turf. This prevents the turf from shifting or lifting.
- Nails or Staples:
- Nails or staples are used to secure the edges and seams of the turf to the edging material and the subgrade.
- Weed Barrier (Optional):
- In some cases, an additional weed barrier fabric may be used between the subgrade and the base material to further prevent weed growth.
The specific materials and layers used can vary depending on the project’s requirements, such as the intended use (e.g., landscaping, sports field, pet area) and local climate conditions. Proper installation is essential to ensure the longevity and performance of the artificial turf, and it’s often recommended to have the installation carried out by professionals with experience in artificial turf installations.
