KomboGrass FAQ

Our warranty when no-sand or rubber infill is used is an 8 year manufacturer backed warranty. In reality you could expect the grass to last 10+ years.

Installing artificial grass is not that hard to do yourself. Depending on the size of the area and access, there are a few steps to follow that will ensure you get a professional looking result. 

KomboGrass provides a technical DIY guide for any customers that purchase our grass range and also offer telephone assistance should you have any questions when you are installing your new lawn.

Depending on the site details, the base material used for the installation of artificial grass includes road base and or crusher dust. When installed and properly compacted, water will run off this surface in a manner similar to an area that was concreted.

To ensure adequate water drainage, existing drains can be used for removal of any pooled water, with the base contoured to ensure the levels fall correctly to the drain. As a rule, KomboGrass does not cut around drains as the water will drain under the grass base and on the crusher dust surface. Exposed drains are generally good for sticks, spiders and little fingers.

Sand infill was needed back in the 60’s when fake grass was first developed, but todays grasses have evolved significantly. KomboGrass uses a polyurethane backing which does not shrink and break down like SBR/Rubber/Latex backing. We also use stronger yarn that is designed to stay straight naturally without the need of any infill.

Artificial grass will get hot but no more than pavers or timber. Fortunately KomboGrass does not require sand infill which makes the grass cooler to walk on (just remember that run to the waters edge at the beach). Our grass range has also been optimally designed to meet Australian conditions to ensure it is as cool as practical, with our longest range being 30mm (longer piled grass is hotter than shorter piled grass). We also offer a ‘Cool’ grass series,  Wintergreen-30, that uses a special treatment to the yarn to reduce the absorption of IR light, and our Kool-30 that uses a unique hollow blade that retains moisture, ensuring the surface temperature of the grass is kept cooler as the moisture evaporates.

Absolutely, in fact was have installed our grass for a veterinary clinic for use as a dog run for pets staying at the surgery. Without sand the grass is much easier to clean and will contain less bacteria, also polyurethane does not absorb moisture unlike SBR or latex backings, and as you can guess, some things don’t mix well with sand!

Over time all synthetic grasses will have small amounts of fading. The result is minimal and generally is only noticeable if you needed to install new artificial grass near the original grass.

In high foot traffic areas artificial grass can become flat. In general areas in full sun light will tend to remain straight, however, in the event that the grass remains flat, you can use a broom or plastic rake to brush the piles up when required.

All councils have their own bylaws regarding what you can do with the nature strip. If you are considering installing grass to that area, it is best to contact your local council for advice. Removing artificial grass from a council owned area can be expensive.

Depending on the site access, whether any timber or other edging is required, if there are any drainage requirements, a typical residential lawn of between 30-50 SQM is usually installed in a day.

Unfortunately glass windows, glass pool fencing, plastic roller blinds, even glass or plastic bottles left on the artificial grass surface can damage the grass. There is no warranty for damage to the artificial grass caused by radiated heat.

Although our grass range has some of the highest rated melting points, with a rated melting point temperature of 120 degrees Celsius,  we have measured areas under glass pool fences and recorded temperatures in excess of 90 degrees Celsius on a 40+ degree Celsius summer day, which will damage our grass range as well as any other synthetic grasses on the market.

Yes and in fact about 30% of our installations are on hard surfaces. Depending on the particular installation, for example roof tops, with water proof membranes need special glues to ensure they are compatible to the membrane installed. Artificial grass is a great way to cover up and transform areas.

By not using sand infill, weeds are generally a minimal problem. KomboGrass edges are bolstered which also reduces the likelihood of weeds growing along the perimeter. However, in the event that weeds do appear, either pull them out by hand, or apply a suitable weed poison, just make sure your test the weed poison on a small area first to ensure it does not damage the grass.

KomboGrass includes fire retardants in all our grass ranges, and the grass has been tested and certified to comply with EN 13501-1:2007+A1:2009 fire classification standard.

Artificial grass terms are similar to those used to describe carpets (with a few additions). The main terms you generally come across are as follows:

  • Gauge – the distance between the stitch runs
  • Seam – the join between different artificial grass sections
  • Bolster – to fold the grass edge into the base material
  • Dtex – stands for Decitex, a term for measuring yarns, the unit measures how many grams per 10000 meters, so it refers to mass or weight of the grass yarn. But don’t be fooled by just a high Dtex rate, the quality of the fiber used means a higher quality lighter fiber may be more suitable than a heavier fiber in a poor quality yarn.
  • Stitch Rate – typically recorded in stitches per 10cm length
  • Pile height – the length of the artificial pile above the backing material. The backing material is typically 2-3cm thick so the total thickness is the pile height plus the backing height
  • U-pin – galvanised and painted steel staple used to secure the artificial grass into the base material
  • Seam Tape – material used to fix different sections of grass together. Glue is applied to this seam tape.
