Playground safety surface and rubber tiles

[Thomas-the-Terrano2]

Are there any members in this trade or can advise on supply and or fitting/laying.

I have an area of our garden about 20 square metres under some swings and looking
for an all weather safe surface. In past had grass and bark.

Was looking at astroturf and rubber beneath but suspects costs are up there with
rubber tiles. Have searched web and ebay, prices seem to vary and it doesnt seem
all rubber tiles are suitable for protection for kids falls.
