What is soft fall?
Soft fall is an impact absorbing layer that is laid beneath the finished surface of your area.
The thickness and level of your impact absorbing layer is determine from the critical fall height (CFH) of the play unit, in most cases the CFH is supplied by the manufacturer.
Soft fall surfaces may be installed using Synthetic Grass or Wet Pour Rubber. Where there is no play equipment the area can be covered with just a “Wear Layer” where there are no soft fall pads used and just a layer of Synthetic Grass or Wet Pour Rubber.
Do I need soft fall?
Soft fall surfacing is required to meet Australian Standards for playground safety. The level and type of soft fall you require will be determined by the play equipment you choose for your area.
Soft fall/Safety Surfacing need only be installed to the required Safe Zone area of the play equipment, the remaining play area may consist of a wear layer.
This kind of installation reduces the cost of your surfacing.
This will depend on a number of factors including the type/surface of area, what it will be used for, personal preference, aesthetic aspects, budget and legal or compliance requirements.

What is Critical Fall Height (CFH)
The Australian Standard AS/NZS 4422:1996 specifies testing requirements that will determine the Critical Fall Height for playground safety equipment. This height is determined by dropping an instrument from various heights onto surfaces and measuring the point where one of the two safety criteria are exceeded.
(see chart below)
The two criteria are the Head Injury Criterion exceeding 1000 and the maximum acceleration due to impact exceeding 200g.
Different thicknesses and types of soft fall determine the critical fall height and thus the height the playground equipment can be.
