How do you lay artificial grass on top of grass?

You cannot effectively lay artificial grass directly on top of existing grass. The first crucial step involves removing the existing turf.

Preparing the Ground for Artificial Grass

The installation of artificial grass requires proper ground preparation to ensure a level and stable surface. Laying it directly on top of natural grass will result in an uneven, bumpy surface that is unsuitable for artificial grass. Here's how to correctly prepare the ground, incorporating the information from the provided reference:

Step-by-Step Guide to Removing Existing Grass

1. Turf Removal:

   • As stated in the reference, you must remove the existing turf. This is the essential first step.
   • Use a shovel for smaller areas.
   • A turf cutter can make the job easier and quicker, especially for larger spaces.

2. Preparing the Area:

   • After removing the turf, you will need to level the area.
   • Compact the soil to create a stable base for your new grass.
   • Consider adding a layer of crushed stone or gravel for extra stability and drainage.

3. Weed Barrier:

   • Lay down a weed barrier fabric to prevent weeds from growing through your artificial grass.
   • This step will help maintain the appearance of your installation long-term.

4. Installing the Artificial Grass:

   • Once the area is prepared, you can then install the artificial grass over this flat, stable surface.

Why Removing Existing Turf Is Crucial

• Even Surface: Directly overlaying the natural grass would cause unevenness due to the existing root system and grass blades. The artificial grass will follow these irregularities, making the surface appear bumpy and unprofessional.
• Proper Drainage: Natural grass and its underlying soil may not provide adequate drainage for the artificial grass, potentially causing water to pool and lead to issues such as mold or mildew.
• Stability: The natural grass will eventually decompose under the artificial turf, causing unevenness and instability to the top layer. Removing the old grass creates a stable, solid foundation, giving the artificial grass a longer life.
