Unveiling the Benefits of Underlay for Artificial Grass

An underlay is a layer of material placed beneath artificial grass to enhance its performance, durability, and comfort. Here are some convincing reasons why using an underlay is a wise choice:

  • Improved Drainage: Underlays feature drainage holes or channels that facilitate the efficient flow of water away from the artificial grass surface, preventing waterlogging and potential damage.
  • Enhanced Comfort: Underlays provide a soft and cushioned layer, making the artificial grass more comfortable to walk and play on. This is especially beneficial for areas with heavy foot traffic.
  • Extended Lifespan: Underlays protect the artificial grass from wear and tear caused by direct contact with the concrete, extending its lifespan and preserving its appearance.
  • Weed Suppression: Underlays act as a barrier against weeds, preventing them from growing through the artificial grass and spoiling its aesthetic appeal.

Types of Underlay for Artificial Grass

Selecting the right underlay is crucial for maximizing the benefits of artificial grass on concrete. The market offers various types of underlays, each with its unique properties:

  1. Permeable Underlay: Made from non-woven geotextile fabric, permeable underlays are designed to allow water to pass through easily. They are ideal for areas with high rainfall or poor drainage.
  2. Closed-Cell Foam Underlay: Closed-cell foam underlays are made from recycled foam materials, providing superior cushioning and insulation. They are suitable for areas that require maximum comfort and support.
  3. Crushed Foam Underlay: Crushed foam underlays are made from recycled carpet padding, offering a combination of drainage and cushioning. They are a cost-effective option for areas with moderate foot traffic.
