We could be biased, but we strongly recommend considering poured rubber and rubber tile playground surfaces.

These certificates are sometimes awarded by way of laboratory testing of surface samples. The requirements require the actual site-put in surface methods to comply with ASTM F1292-ninety nine/04 and ASTM F1951-ninety nine. The floor for the accessible route throughout the play space must meet the technical provisions of the standards so long as it's open for public use.
