Looking forward to installing synthetic grass in your garden for the first time?
Synthetic grass is great for modern gardens thanks to its low upkeep, low maintenance costs, and long-lasting materials. It’s also great for homeowners who want more flexibility in designing their garden.
However, one thing that many potential owners (and even existing owners) don’t realise is that you have to replace the infill of synthetic grass once every few years.
While it may seem inconvenient, replacing your lawn’s infill is very simple; our guide today will cover everything you need to know about synthetic grass infill and why is it so important for your garden.
Synthetic grass infill is a type of material (normally green coloured sand) that is put in between synthetic grass for several reasons.
There are 3 main types of infill: silica, crumb rubber, and organic infill.
Over here at BuildMat, we provide silica infills for homeowners as it is the best choice for people who want synthetic lawns that feel and look natural.
Silica sand infill is the original infilling material for synthetic grass as it is safe, cheap, and natural. What we mean by safe is that silica sand is non-toxic and is chemically stable which means that you don’t have to worry about being harmful to the people around you.
Silica sand provides durability and strength to your synthetic grass as well as preventing bacteria from growing. Your grass will also feel natural as you are using sand similar to the ones in natural grass.
The alternative to silica sand is crumb rubber infills. Crumb rubber infills are usually made up of recycled tyres and rubber. It is safe and has been approved for use by worldwide guidelines and agreements.
Rubber crumb infills can be used in conjunction with silica sand to provide even more support; it can also be used by itself. However, rubber crumb infills are rather rough on the feet and it can look off-putting to some homeowners as it is dark in nature.
Organic infills are made from natural products such as corks or coconut skin. These infills can be recycled and reused but it is expensive and very hard to get outside of North America.
Think of synthetic grass infill or sand as a material that supports the structure of your fake grass lawn. Infill allows the fibres of synthetic grass to stand firm which makes it look and feel like natural grass.
Without it, the fibres of the grass will “wilt” or lay down which makes the appearance of synthetic grass look a bit unattractive. The infill also weighs down and stabilises the artificial grass which makes it stay in place.
In summer and winter, the infill also keeps your synthetic grass in shape; you won’t need to stretch and reshape it every time the season changes which can make your synthetic grass look like a carpet if you don’t have infill.
In addition to that, grass infill also helps to achieve:
There is no definite measurement for the amount of infill that you need for your lawn. A rule of thumb to follow is that your infill should be laid to a depth of 1/4 of your synthetic grass’ height.
This means that you will need about 2-3 kg of infill (5-6 lbs) to maintain your lawn. Generally, having too much infill is a better choice than having too little infill.
If you are unsure of how much you need, you can consult your synthetic grass provider and ask them about the details of your synthetic turf’s infill.
Over here at BuildMat, we have a 25kg bag of silica sand infill for $12 AUD.
We can’t provide an accurate estimate of the average cost due to differences such as business models and the infill material.
Our rates, however, are the best in the market. Our silica infill is also very high-quality and has been approved by national regulatory bodies.
Ideally, you’d want to replace it once every 3-4 years. If you are concerned about the structure of the grass, replacing it every year is not an issue but modern infills last for a very long time.
We don’t recommend doing that as it can:
The Wikipedia page for synthetic grass is also useful if you would like to know more about the research and technical side of artificial grass.
