Introduction
Understanding the foundation beneath artificial grass is essential for achieving a durable and high-performing surface. Turf underlayment, often overlooked, plays a crucial role in enhancing stability, cushioning, and drainage. These factors directly influence the longevity of the installation. Various materials are available, ranging from foam pads to rubber rolls, each offering unique benefits tailored to specific needs. However, selecting the right underlayment can be challenging. What factors should be considered to ensure optimal performance and avoid costly mistakes?
Define Turf Underlayment: What It Is and Its Purpose
When considering what do you put under turf, turf underlayment refers to the layer of material placed beneath artificial grass, providing essential support, cushioning, and drainage. Its primary role is to enhance the performance of the grass surface by ensuring stability, preventing shifting, and improving drainage.
Underlayment materials can vary significantly, including:
- Foam pads
- Rubber rolls
- Geotextile fabrics
Each type serves specific functions, such as:
- Shock absorption
- Weed prevention
- Moisture management
Understanding the role of this base layer is crucial for achieving optimal results in grass installations, as it directly impacts the longevity and functionality of the surface above.

Explore Underlayment Options: Types and Benefits
When it comes to synthetic grass installation, knowing what do you put under turf is crucial for ensuring durability and performance. The primary options available each offer distinct advantages:
-
Foam Pads: These pads excel in shock absorption, making them particularly suitable for playgrounds and sports fields. They significantly reduce the impact of falls, enhancing safety for users, especially children. Regular inspections of these pads can further ensure their effectiveness in maintaining safety standards.
-
Rubber Rolls: Known for their exceptional durability, rubber underlayment is designed to withstand heavy foot traffic, making it a preferred choice for commercial applications. Their drainage characteristics help prevent water buildup, which can damage the grass. Research indicates that rubber surfaces have a lower injury rate compared to other materials, making them a wise investment for high-use areas.
-
Geotextile Fabrics: Primarily serving as weed barriers, geotextile fabrics prevent unwanted plant growth while allowing water to drain effectively. This is essential for preserving the integrity of the grass surface and ensuring long-term functionality.
-
Shock Pads: Specifically engineered for sports applications, shock pads enhance cushioning and improve player safety by minimizing the risk of injuries during play. Evidence supports that proper safety surfacing can significantly reduce the likelihood of severe injuries, such as fractures and concussions.
When deciding what do you put under turf, choosing the appropriate layer not only impacts the short-term functionality of the synthetic grass but also contributes to its durability, ensuring that the investment remains worthwhile over time.

Considerations for Choosing the Right Underlayment
When selecting the appropriate materials, it’s important to consider what do you put under turf to ensure optimal performance and longevity.
Intended Use: The purpose of the turf installation – whether for a residential lawn, playground, or sports field – will dictate the type of underlayment required. For example, playgrounds necessitate more cushioning than decorative lawns to ensure the safety of children.
Drainage Requirements: Adequate drainage is essential to prevent water accumulation and potential damage to the grass. Improper drainage can lead to significant issues, including waterlogging and mold growth, which compromise the integrity of the turf. Utilizing resources such as geotextile fabrics or rubber rolls with drainage capabilities is advisable in regions prone to heavy rainfall. As Jason Kruse notes, “Proper drainage systems are crucial for maintaining the integrity of artificial grass fibers by preventing excess water accumulation.”
Foot Traffic: Areas with high foot traffic require more durable underlayment options, such as rubber rolls, designed to withstand wear and tear. These materials are specifically engineered to endure the regular use associated with sports fields and playgrounds.
Budget: Cost considerations also play a significant role in the selection process. While premium materials may incur a higher initial expense, they often provide greater long-term value through durability and efficiency. For instance, investing in high-quality materials can reduce maintenance costs over time, making it a financially sound decision. The estimated reinstallation cost for artificial turf is USD 1,114,608 every ten years, highlighting the importance of selecting the right materials from the outset.
Environmental Conditions: Local climate and soil conditions can influence the choice of base material. For instance, areas with dense clay soil may require additional drainage solutions to ensure optimal performance and prevent water buildup.
By thoroughly assessing these factors, homeowners and contractors can select the most suitable base layer for their specific grass installation needs, ensuring both functionality and durability.

Understand the Installation Process: Best Practices for Underlayment
To achieve optimal performance and durability, the installation of grass padding is essential. Here are the key steps to follow:
-
Site Preparation: Begin by removing debris, grass, and weeds from the installation area. This creates a clean and stable base for what do you put under turf. Proper site preparation is crucial; neglecting this step can lead to uneven surfaces and potential issues later on.
-
Leveling the Ground: Ensure the ground is level and compacted. This prevents shifting or settling over time, which is vital for maintaining a smooth surface. A well-leveled foundation is crucial for understanding what do you put under turf to significantly contribute to the grass’s durability.
-
Laying the Base Layer: Roll out the base layer material evenly across the prepared area. If using foam pads, ensure they fit snugly together without gaps. For geotextile fabrics, overlap the edges to inhibit weed growth. Additionally, to improve the stability and functionality of the grass, it’s important to consider what do you put under turf, such as infill like silica sand.
-
Securing the Base Layer: Fasten the base layer using landscape staples or adhesive, particularly in high-traffic areas, to prevent movement. This is a common oversight that can lead to functionality issues with the grass.
-
Final Checks: Before placing the grass, confirm that the underlayment is smooth and free of wrinkles or folds. Such imperfections can adversely affect the grass’s appearance and performance. Experienced installers often stress that attention to these details can significantly influence the final outcome.
By following these best practices, homeowners can ensure a successful installation, resulting in a durable and visually appealing artificial turf surface.

Conclusion
Selecting the appropriate underlayment for synthetic turf is crucial for optimizing its performance and extending its lifespan. The underlayment not only provides stability and cushioning but also plays a vital role in drainage and weed prevention. By familiarizing themselves with the various materials available – such as foam pads, rubber rolls, and geotextile fabrics – homeowners and contractors can make informed choices that enhance the overall quality of their turf installations.
This article highlights the key advantages of each type of underlayment, stressing the importance of choosing the right material based on:
- Intended use
- Drainage requirements
- Foot traffic levels
- Budget constraints
