Artificial grass has become a popular choice for homeowners seeking low-maintenance, aesthetically pleasing grass. While it eliminates the need for mowing and watering, artificial grass still requires some care to maintain its appearance and durability. One of the key factors in ensuring the longevity and well-being of your artificial turf is the use of a sand infill. This comprehensive guide will explain how sand infill benefits your artificial grass, how to install it, and why it’s a crucial component for a beautiful and lasting lawn.
What is Sand Infill and Why is it Important?
Sand infill refers to the layer of sand spread across the surface of artificial grass, providing numerous benefits that enhance both the appearance and performance of the turf. Sand is highly durable, and when used as infill, it will contribute greatly to the longevity of your artificial grass, especially in high-traffic areas. Over time, it helps maintain the natural look and feel of the grass while also supporting the structural integrity of the installation.
Benefits of Using Sand Infill:
- Maintaining Grass Blades’ Upright Position: The sand granules surround the individual blades of artificial grass, helping them stay upright. This prevents the turf from becoming flattened or matted over time, ensuring that your lawn looks fresh and lush. The weight of the sand supports the blades, giving your garden a neat and presentable appearance.
- Stabilising the Artificial Grass and Weed Membrane: One of the most crucial functions of sand infill is keeping both the artificial grass rolls and the underlying weed membrane in place. Without a solid foundation, your artificial lawn can shift, causing unsightly creases and folds. By adding the recommended amount of sand, you ensure that your turf stays smooth and secure for many years.
- Preventing Weed Growth: While the weed membrane does much of the heavy lifting in stopping weeds from sprouting through your artificial lawn, the sand infill adds another layer of protection. By weighing down the grass and membrane, it prevents gaps where weeds could potentially grow.
- Durability in High-Traffic Areas: In areas where foot traffic is frequent, such as pathways, children’s play areas, or near patios, the artificial grass can wear down more quickly. Sand infill acts as a cushion, absorbing the impact of footsteps and preventing wear and tear on the grass blades.
- Child and Pet-Friendly: A sand-infused artificial lawn is not only soft underfoot but also safe for children and pets. It can withstand the energetic play of children and the activities of dogs and cats without compromising its integrity. Non-sand-filled areas are often more susceptible to damage, especially if you have pets that like to dig or run around. The sand acts as a buffer, protecting the base of the grass from such damage.
- Weighing Down Uneven Surfaces: Artificial lawns installed on uneven ground or areas with slight inclines can sometimes shift out of place. Sand infill helps by weighing down the grass, keeping it firmly in place and preventing it from shifting over time, even in challenging terrain.
Choosing the Right Sand Infill
When selecting the right type of sand infill for your artificial grass, it’s important to think about the long-term benefits. A high-quality infill will not need to be replaced frequently, saving you money in the future.
There are two main types of sand infill commonly used for artificial grass:
- Silica Sand: Silica sand is one of the most widely used infills. It consists of small, angular grains of sand that efficiently keep the grass blades upright. Silica sand is also resistant to harsh weather conditions, making it a durable option for homeowners.
- Kiln-Dried Sand: This type of sand is often preferred for its ability to absorb moisture, which helps prevent water pooling on the surface of the grass. Kiln-dried sand is particularly useful in areas with frequent rainfall, as it ensures the drainage system works effectively.
Whichever sand you choose, it’s important to apply the recommended quantity. On average, it is advised to use approximately 4kg of sand per square metre of artificial grass. This ensures even coverage and provides all the benefits outlined above.
How to Install Sand Infill
Now that you understand the importance of sand infill, it’s time to learn how to install it properly.
Tools You’ll Need:
- Sand (silica or kiln-dried)
- Drop spreader or a shovel
- Rake
- Broom (a stiff-bristled broom works best)
Step-by-Step Installation:
- Prepare the Surface: Before applying sand infill, make sure your artificial grass is properly laid and secured. Check that the seams are joined correctly and that the grass is free from debris. If there are any creases or bumps, smooth them out as much as possible before moving forward.
- Spread the Sand: Using a drop spreader or a shovel, evenly distribute the sand across the surface of your artificial grass. For best results, apply around 4kg of sand per square metre. Be sure to work in small sections to ensure even distribution.
- Rake the Sand: After spreading the sand, use a rake to work it into the grass fibres. This will help the sand settle between the blades and reach the base of the turf.
- Brush the Grass: Once the sand has been raked into place, use a broom to brush the grass blades upwards. This ensures that the sand supports the blades properly, keeping them upright and giving the turf a lush, natural appearance.
- Water the Grass (Optional): Some people choose to lightly water the grass after applying the sand infill. This can help settle the sand further and improve its integration into the turf.
Conclusion
Using sand infill for your artificial grass is essential to maintaining a pristine and long-lasting lawn. It stabilises the turf, keeps the blades upright, and protects the base of the grass, making it more durable in high-traffic areas. With the right type of sand and proper installation, your artificial grass will look and feel natural for years to come, providing a child- and pet-friendly space that the whole family can enjoy.
