Providing a suitable floor within the
playground is extremely important because most injuries in playgrounds are
caused by falls. For a maximum fall height of more than 1 m, one of the
following materials is recommended:
Loose
material 
TYPES: sand, bark, wood shavings, shredded
rubber or gravel
IMPORTANT INFORMATION The thickness of the
layer should be 30 cm, unless the tests confirmed by a certificate indicate
otherwise.
WHAT SHOULD BE REMEMBERED? Surfaces made of
loose materials require regular checking of their appropriate level and
supplementing any losses, however, due to the low cost of execution, they are
very popular and willingly used.
Synthetic
surface
TYPES: surface in the form of poured or in
the form of rubber tiles
IMPORTANT INFORMATION Available in a wide
range of colors, it does not pose any problems with current maintenance.
WHAT SHOULD BE REMEMBERED? You only need to
take care of regular removal of rubbish from it, e.g. broken glass.
Artificial
grass surface 
IMPORTANT INFORMATION It is a solution
cheaper than a synthetic surface.
WHAT SHOULD BE REMEMBERED? Unfortunately,
this is not a "maintenance-free" surface, because its operation
involves the costs of refilling, filling and systematic sweeping (using
specialized tools).
Safety surfaces according to standards PN-EN1177 and PN- EN 1176:
