Choosing the best artificial grass for your play area or school is a crucial decision that impacts safety, durability, and overall play experience. Schools and contractors must consider various factors, including critical fall height protection, sub-base specifications, and maintenance requirements, to ensure a long-lasting and safe play surface.
With extensive experience in installing artificial grass for both contractors and schools, Abacus Playgrounds provides high-quality, durable solutions tailored to different project needs. This guide will walk you through the key factors to consider when selecting artificial grass surfacing for playgrounds and schools, helping you make an informed decision.
1. Safety Considerations
Safety should always be the primary concern when selecting artificial grass for playgrounds or play areas. Ensuring compliance with industry standards and using the right materials can significantly reduce the risk of injuries.
Critical Fall Height Protection
Playgrounds and Play Areas often feature climbing frames, slides, and other elevated structures where falls can occur. To ensure adequate impact absorption, it is crucial to select artificial grass systems that include a shock pad layer. The thickness of this layer determines the Critical Fall Height (CFH), which indicates the maximum height from which a child can fall without sustaining serious injuries.
Below is a general guideline for artificial grass installation over a stone sub base and recommended Shockpad thickness:
| Critical Fall Height – CFH (m) | Abacus Rubber Shockpad Thickness (mm) |
|---|---|
| 0.9 m | 20 mm |
| 1.4 m | 40 mm |
| 1.8 m | 60 mm |
| 2.63 m | 100 mm |
| 3.0 m | 140 mm |
Non-Toxic and Child-Friendly Materials
Artificial grass should be made from non-toxic materials, free from harmful chemicals such as lead or heavy metals. This ensures that children can safely play without exposure to hazardous substances.
Fire Resistance and UV Stability
Look for artificial grass with fire-resistant properties and UV stability to prevent premature fading or deterioration due to sun exposure. High-quality turf maintains its colour and texture over time, even with constant outdoor exposure.
2. Durability and Maintenance
Artificial grass should withstand heavy foot traffic and remain in good condition for years. Schools, nurseries, and public playgrounds experience high levels of activity, so choosing a durable product is essential.
High-Density Turf for Maximum Durability
The durability of artificial grass depends on factors such as pile density, fibre type, and backing material. Typically, the denser the pile, the better it will resist wear and tear. A minimum of 16,000 stitches per square metre is recommended for high-use playgrounds and school fields.
Low Maintenance Requirements
Unlike natural grass, artificial turf does not require mowing, watering, or fertilising. However, periodic brushing and debris removal will help maintain its appearance and performance. Ensuring proper drainage and avoiding heavy objects on the surface will also extend its lifespan.
3. Aesthetic and Functional Features
Artificial grass should not only be practical but also visually appealing and functional for a variety of activities.
Realistic Look and Feel
Modern artificial grass closely mimics natural grass in terms of colour, texture, and feel. Opt for turf with a blend of different shades of green and a soft, non-abrasive surface for a more natural appearance.
Excellent Drainage Capabilities
Proper drainage is essential to prevent water accumulation and ensure year-round usability. The best artificial grass for playgrounds incorporates a high-permeability backing that allows rainwater to drain efficiently, reducing the risk of puddles or mud.
4. Sub-Base Specifications
A well-prepared sub-base is crucial for a stable and long-lasting artificial grass installation. Below are the key steps involved in sub-base preparation for playgrounds and school fields:
Excavation
Remove the existing turf and topsoil to a depth of at least 150mm. Ensure a level surface free from debris or roots that could cause unevenness.
Sub-Base Installation
Lay a minimum 100mm layer of MOT Type 1 crushed stone, compacted to create a stable foundation. Ensure the compacted base has minimal deviations (no greater than 10mm under a 3m straight edge).
Regulating Layer
Apply a 35mm compacted regulating layer to provide a smooth, level surface.
Perimeter Edging
Install concrete edging (PCC) or treated timber edging to retain the surface and prevent movement.
5. Installation Best Practices
For a long-lasting installation, following best practices is essential. Whether you are a school handling the installation directly or a contractor subcontracting the work, proper techniques ensure a durable and high-performance surface.
Professional Installation
Hiring experienced installers guarantees that the artificial grass is properly secured, laid evenly, and bonded correctly. Poor installation can lead to ripples, lifting edges, and drainage issues.
Joining and Seaming Techniques
Use high-quality adhesive and joining tape to secure seams. Ensuring seamless joins enhances the aesthetics and safety of the play surface.
6. Cost Considerations
Artificial grass is an investment that provides long-term benefits. While the initial cost may be higher than natural grass, the reduced maintenance costs make it a cost-effective solution over time.
Balancing Quality and Budget
Schools and contractors should balance budget considerations with long-term durability. Cheaper options may deteriorate quickly and require replacement sooner, leading to higher overall costs.
Financing and Grants
Some schools may be eligible for grants or funding to support playground improvements. Exploring financial assistance options can help make high-quality artificial grass more accessible.
Choosing the best artificial grass surfacing for a playground or school requires careful consideration of safety, durability, aesthetics, and installation requirements. By selecting a high-quality product with the appropriate shock pad thickness, ensuring proper sub-base preparation, and following best installation practices, schools and contractors can create a safe, long-lasting, and visually appealing play area.
