How to Install Artificial Grass: A Step-by-Step Guide
Measure and sketch the planned synthetic grass area indicating the direction of the grass. (Check
and identify any underground services such as electrical wires, irrigation systems, gas pipes etc. that
can be damaged during the installation). Calculate the amount of grass required (2m and 4m widths
and lengths up to 25m) and indicate on the sketch. Calculate the rest of the materials required
including the crushed rock, crusher dust (70% crushed rock 30% crusher dust on an 80mm – 100mm
base), weed mat (similar amount to grass). Infill (graded sand or ZeoFill), edging (Benda board or
timber), joining tape, glue, nails, or U – Pins, skip bins (only for excavation and disposal jobs).
Installation Equipment List:
Knife (Stanley knife), hammer, machine compactor, hand compactor, power broom, digging shovels,
normal shovels, mattock, levellers, spreaders, spirit levels, string lines, sand spreader, power broom,
different type of saws or grinders if required and any other specialised tool to complete the job.
Note: for direct stick installation on a concrete surface skip step 1 and 2.
Step 1: Surface Preparation
Remove the existing surface (80mm – 100mm) if required to match the surround heights/ required
finish height. Use a skip bin to dispose the excavated material. Install an edge using timber or Benda
board if required to ensure the base material stays in place. Use stakes and pickets to secure the
edging to the surface. Install edging around any trees or plants to ensure sufficient water flow to the
Step 2: Base Preparation
Place the weed mat on the excavated or the natural surface. Fill the area with crushed rock up to
70% of the depth. Level and compact the area using the compactor (use a hand compactor to
compact any edges). Fill the last layer of the base with crusher dust (blue metal dust) up to 30% of
the depth. (Ensure the base is levelled and the falls are away from the house to ensure the drainage
of the water) Dampen the area with water while compacting to achieve a solid base. Any uneven
areas after the compaction can be filled with crusher dust and can be tampered with a hand
compactor for a smoother surface.
Step 3: Laying the Synthetic Grass
Lay the grass pieces in accordance with the plan and ensure the grass yarns are facing towards the
direction on the plan (tip: lay the grass towards where you can see most of the grass from). Cut the
edges/trim as required. Use joining tape to join the grass (self-adhesive joining tape or glue tape).
Secure the grass with spiral nails and U- pins (tip: use U shape pins on the joints. Use extra nails in
high traffic entering points) Ensure you use the nails or pegs every 30cm around the perimeter. Use
commercial graded double-sided tape or glue to secure the grass to a concrete surface if required.
Step 4: Infill and Clean
Infill the grass with a sand/seed spreader to ensure an even spread of the infill. ZeoFill combined
with sand to be used for dog areas and graded sand to be used in normal landscape areas. Use a
power broom to brush the grass (tip: brush the grass against the yarn direction). Finally clean the
working space and enjoy your new synthetic lawn for years to come.
