Typically, geotextile fabric (or geotextile mat) is used under synthetic grass. It's the most common and recommended underlayment.
Here's a breakdown of what geotextile fabric is and why it's important:
What is Geotextile Fabric?
Geotextile fabric is a permeable textile material made from synthetic fibers like polypropylene or polyester. It is designed to be durable and withstand the elements.
Why Use Geotextile Fabric Under Synthetic Grass?
Here are the key reasons to use geotextile fabric under synthetic grass:
-
Weed Prevention: It acts as a barrier to prevent weeds from growing up through the synthetic grass. This keeps your artificial lawn looking pristine and reduces maintenance.
-
Soil Stabilization: Geotextile fabric helps to stabilize the soil beneath the synthetic grass. This is crucial for preventing the ground from shifting or settling, which can cause unevenness and damage to the artificial turf over time.
-
Drainage: It allows water to drain through, preventing water from pooling under the synthetic grass and leading to mold, mildew, or other issues.
-
Extends Turf Lifespan: By providing a stable and well-drained base, geotextile fabric helps to extend the lifespan of your synthetic grass.
Alternatives to Geotextile Fabric
While geotextile fabric is the most popular choice, other materials may sometimes be used depending on the specific application:
-
Gravel base: While gravel itself is not used under the grass directly, it forms the base layer upon which the geotextile fabric and then the synthetic grass are placed. It provides excellent drainage.
-
Other specialized underlayments: Some manufacturers offer specialized underlayments designed for specific purposes, such as shock absorption for playgrounds or enhanced drainage for pet areas.
Key Considerations
-
Proper Installation: Correct installation of the geotextile fabric is essential for it to function effectively. This includes ensuring proper overlap of seams and securing it to the ground.
-
Quality of Material: Choose a high-quality geotextile fabric that is designed for outdoor use and can withstand the rigors of the environment.
In summary, geotextile fabric provides crucial benefits under synthetic grass, including weed prevention, soil stabilization, and proper drainage, ultimately contributing to the longevity and appearance of your artificial lawn.
