No-sand infill artificial grass

When pioneering no-infill artificial grass to the Australian market back in 2012, we used to receive a lot of push back from a range of grass manufacturers as well as artificial grass suppliers that the sand infill was required to protect the grass and keep it standing up straight.

Today we hear from our customers that other suppliers and installers are finally now offering no-infill synthetic grass. Although we encourage this in the industry, be careful that this is not just the sales person making an ambit claim and that there is a genuine manufacturer backed warranty available if no sand is used.

SBR backed or Latex backed grass in general will not be suitable for no-infill applications. To identify latex backing either ask the supplier or simply visually check the back of the grass, SBR or Latex rubber is the same material used for car tyres. It is dull to look at and if you roll the backing in your fingers it is easily broken. Ask the sales representative to provide a written warranty from their supplier in the case when no sand infill is used.

Why adding any infill is a false economy

Since artificial grass must be installed over a base with a fall to support water run off, the sand poured over the surface of the grass will over time also be washed to the lowest point in the area. To compensate for this, constant maintenance is required to brush up the sand as it is washed down to the lowest area and replenishing the sand that actually washes away. Drains are easily blocked with the sand or rubber pellets over time. Not exactly a low maintenance option.

On a windy day sand likes to blow around and if you have pool areas you can guess where that sand will end up. For the maintenance of artificial grass most people either use a rake or an outdoor blower vacuum. Sand and a vacuum are not a good option, neither is using the blower part to remove debris, as the sand will also be blown away.

Repair work for sand infill grass is very expensive – picture youself lifting hundreds of kilograms of sand stuck in the grass fibers to try and replace a section of damaged grass! Replacement is even more expensive and will become even more expensive as councils and local government bodies begin to recover the real cost for managing landfill.

For those that love their pets, well you can guess what pets do on a lawn and this is where the backing on the synthetic grass is critically important. Unlike Polyurethane backings, SBR or Latex backings absorb moisture. Add sand or rubber pellets to the mixture along with your pet dog or cat and you get the picture, some things just don’t mix well, and imagine if you have little children crawling over that same area knowing the sand is keeping a few souvenirs shall we say.

Finally it just makes no sense. With all our technological advancements in material science why on earth would any manufacturer make a range of artificial grasses that cannot be used until you put up to 15 kg of sand for every square meter of grass?

New players on the market or are they?

There are some companies now offering polyurethane backed grasses for no-infill applications, which does address the issue of the backing cracking and shrinking over time. However, unless these companies are using higher quality yarns with stronger tensile strength, these yarns will still go flat and will require some infill to keep them looking natural. There are also a lot of expertise required to install no-infill artificial grass. If you want to know you are getting a product specifically designed for no-sand infill and will be professionally installed then contact the experts at KomboGrass, we now supply our grass nationally and can provide shipping and technical assistance no matter where you live.
