Grasspave2: a Wheelchair Accessible Surface

Grasspave2 has successfully met the manueverability requirements for ASTM F 1951-08 and it has successfully passed the Rotational Penetrometer Surface Tests – making Grasspave2 the only grass porous paver to meet the intent of the ADA. These tests confirm what we've known for many years... Grasspave2 is great for parking, driving, walking and rolling. Learn more about Invisible Structures' commitment to accessible surfaces.
