The sensible landscaping solution for large and small areas.


Step 1: ‘Set out’ area

Area is marked out for excavation.

Step 2 : ‘Excavation’

Excavate by shovel or the use of a dingo/bobcat.

Depending on the likely traffic on the area we recommend the excavation to a depths as follows:

  • 80 to 100mm for non-vehicle areas
  • 150mm when heavy items such as vehicles may drive on the area
  • Ensure a slight fall across the area for water run off

Step 3: ‘Fill with crushed rock’

Once the area has been completely excavated and any loose rumble is removed, fill the area with crushed rock and level out with a rake to a depth of approximately 15 to 20mm below any surrounding footpath or edging. This level will drop after compaction.

Step 4: ‘Wet and compact’

Thoroughly wet the entire base area and then compact with vibrating plate. After compaction check the crushed rock base is now 25 to 30mm below original surface.

Step 5: ‘Base finishing’

Ensuring the area is 25 to 30mm below the finishing level, fill the area with ‘crusher dust’ to approximately 5mm below the finishing level. Screed the entire area level and once again thoroughly wet the entire area and compact with vibrating plate. Make sure no stones are protruding above level surface.


Step 6: ‘Roll out grass’

Determine the best edge to begin rolling out your Gecko synthetic grass. The longest and straightest edge is the best to start with. Ensure the Grass rolls are all laid in the same direction each time.

Step 7: ‘Cutting in’

Cut off excess synthetic grass with a sharp knife from the back side. To ensure straight cuts, use the same row of yarn as your latex backing. When cutting in around the edge areas take your time and only cut a small distance before checking regularly for accuracy.


Step 8: ‘Joining the grass’ & ‘Pinning the edges’

Fold back the seams of both rolls and ensure the backing is dirt free and dry. Using Gecko’s ‘self-adhesive’ synthetic grass tape roll it out so it is positioned centre to the grass joined when it is laid back down.

The final step before infilling the grass is to pin the edges with Gecko’s 150mm Anchor nails. Using Gecko’s anchor nails to secure the grass edges, nail in through the top of the synthetic grass around the entire perimeter at approximately 300mm apart and about 25mm in from the grass edges.


Step 9: ‘Infilling grass’

Before adding any infill into your synthetic grass leave it warm up in the sun which will natural lift the grass blades, or alternatively use a stiff bristle broom to brush against the grass blades/pile. By lifting the grass blades it will allow the infill to fall into your synthetic grass easily rather than sitting on the top.

Evenly spread Gecko’s silica sand (which doesn’t retain moisture) and broom into the grass. It is better to apply smaller amounts at a time to ensure a more even application.

Then with either a stiff bristle broom or a power broom brush in the sand infill so there is no evidence of the sand remaining on top.

Finally as an option you may infill your synthetic grass with rubber crumb granules. This adds depth in colour to your new grass surface and provides a softer feel under foot.


Step 10: ‘Ready for use’

Congratulations!!! Now your new Gecko synthetic grass lawn is ready for immediate use.
