Most synthetic grass unlike “Ausgrass” requires an infill after installation. Periodically this infill process needs to be carried out when the grass becomes flattened. This is particularly important when synthetic grass is used for sporting or high use areas.

So what is the infill material?

The infill material is basically silica sand and rubber granules used to infill the grass blades. It serves three purposes:

1. It keeps the fibres in the upright position.
2. The sand adds to the weight of the grass carpet.
3. The rubber granules provide cushioning.

Dried, washed quarts silica sand ( 80% round, size 0.3mm – 0.8mm) is used as the first layer of infill material. The next layer consists of SBR rubber granules (size 0.3 -2.5mm) and acts as cushioning or shock absorbency in order to meet FIFA and critical fall height specifications and standards. In the first months or two the infill material is noticeable between the grass blades but following the initial settling in period, it will become less visible.

So is infill harmful?

Numerous times the question is raised whether or not the rubber granules are harmful to children if taken orally. Rubber does not taste good and the child will not go for a second bite. The small size of the granules makes it tricky to pick up and the child will quickly lose interest. No harm will be done if consumed once or twice. A number of tests and studies have been made on the use of rubber crumbs and it was concluded that the rubber does not impose a health hazard to either children or players. There again I don’t think I would want my child sampling it.

Infill can be annoying specially if used around a pool as when first applied and for some days can be blown around subsequently ending up in your pool. The sand on the bottom and the rubber granules floating on top. The process of infill maintenance is also an extra chore that you could do without.

What does this infill maintenance consist of?

Sand is distributed over the synthetic grass area then brushed in either with a stiff hand brush or a powered broom. Some distributors of synthetic grass that requires infilling sometimes have power brooms for hire.

So why doesn’t “Ausgrass” require infilling? This is because of the high density of the Ausgrass fibres. The specifications of Ausgrass can be read on our “Product Information” page.

Considering that one of the main reasons for you installing synthetic grass was to cut down on the time undertaking maintenance it seem incongruous that you are adding a chore like this.
