Yes, silica sand is generally considered safe and is a widely used infill material for artificial grass installations. It plays a crucial role in the performance and longevity of the turf system.
Understanding Silica Sand Infill
Artificial grass often requires an infill material spread between the fibers. This infill serves several important functions. Silica sand, specifically washed and kiln-dried varieties with rounded grains, is a popular choice for this purpose in many residential and commercial artificial turf applications.
Benefits of Using Silica Sand Infill
Utilizing silica sand as infill provides numerous practical benefits for artificial turf, contributing to both its performance and feel. According to sources, silica sand infill offers significant advantages:
- Enhanced Drainage: It aids drainage and prevents standing water from accumulating on the surface, allowing water to flow through the turf system efficiently.
- Cushioned Base: It provides a smooth and cushioned base underfoot, enhancing comfort.
- Improved Comfort: This cushioned layer makes the artificial grass more comfortable to walk or play on.
- Blade Support: The sand helps to keep the artificial grass blades standing upright, maintaining the turf's natural look and feel over time.
- Weight & Stability: It adds weight to the turf, helping to hold it down and prevent wrinkles or shifting, contributing to overall system stability.
- UV Protection: The infill helps protect the backing of the artificial grass from harmful UV rays, which can extend the turf's lifespan.
By providing these benefits, silica sand contributes positively to the functionality and durability of artificial grass, which is why it is a standard and safe component in many installations.
Why is it Safe?
When used correctly as infill in an artificial grass system, the silica sand is typically installed beneath the visible fibers and remains largely in place. High-quality infill sands are processed to minimize dust and have grain sizes suitable for turf applications, reducing potential airborne particle issues once installed and settled.
Key Benefits Summary
Here's a quick look at the main advantages silica sand brings to artificial grass:
| Benefit | Description |
|---|---|
| Drainage | Improves water flow, prevents puddles. |
| Comfort | Creates a softer, more walkable surface. |
| Blade Support | Helps fibers stand upright, maintains appearance. |
| Stability | Adds weight, keeps turf flat and stable. |
| Protection | Helps shield turf backing from sun damage. |
In conclusion, silica sand is not only safe but also highly beneficial for artificial grass, playing a key role in its drainage, stability, comfort, and appearance.
