The value of Critical Fall Height (Critical Fall Height), also known as HIC (Head Injury Criterion), is an important indicator of the safety of rubber tiles. It was developed to prevent serious head injuries of children. This value tells you the height from which someone can fall on the paving in question without suffering serious head injuries, thanks to the cushioning properties of the paving. For all kinds of playground equipment, the necessary HIC value of the ground must be determined, and you have to choose the kind of paving accordingly.
