The base for artificial turf, also known as the sub-base or foundation, is a critical component of the installation process. It provides stability, proper drainage, and a level surface for the artificial turf to be placed on. Here’s a detailed explanation of the typical layers that constitute the base for artificial turf:
Excavation and Grading:
The existing natural ground is excavated to a certain depth, ensuring a smooth and level surface. The ground is graded to achieve the desired pitch and slope for proper water drainage.
Sub-Base Preparation:
After excavation, a sub-base layer is created using a mixture of crushed aggregate materials. This sub-base provides stability and helps with water drainage. The sub-base should be compacted thoroughly to prevent settling and unevenness.
Geotextile Fabric Installation:
A geotextile fabric or weed barrier is placed over the compacted sub-base. This fabric helps prevent weed growth and provides separation between the sub-base and base layers.
Base Material:
Depending on the specific project and requirements, a layer of decomposed granite (DG), crushed gravel, or crushed rock is spread and compacted over the geotextile fabric. This base layer acts as a transition between the sub-base and the turf.
Shock Pad or Foam Underlay (Optional):
In some installations, especially in sports fields, a shock pad or foam underlay may be added on top of the base material. This adds cushioning and impact absorption, enhancing safety and performance.
Artificial Turf Installation:
Finally, the artificial turf rolls or pieces are laid out on top of the base. Proper positioning and alignment are crucial during this step. The turf is anchored to the edges, and seams are carefully joined to achieve a seamless appearance.
The base for artificial turf is fundamental to ensure the longevity and performance of the turf. Properly preparing and constructing a solid base helps prevent issues such as uneven surfaces, poor drainage, and premature wear and tear of the turf. It’s essential to follow industry best practices and manufacturer guidelines during the installation process to achieve a durable and visually appealing artificial turf surface.
