Rubber Tiles Playground Surfacing
Rubber tiles are a long-standing solution to playground surfacing requirements. They are slightly less expensive than Wet Pour, and they come in a variety of colour options to give you the option of patterns.
If you pick rubber tiles as a surfacing option you will need a solid base and to make sure that the surface is level and true.
They need a little more maintenance than some other surfaces as dirt can collect in the grooves. But they are easy to extend if you increase your playground size.
