The Germantown Fire Department required onsite testing for the Hospital fire lane installation. Invisible Structures recommends testing with grass grown on the system (with two weeks of rooting), however even without grass, this installation passed with flying colors. Even with the fully extended ladder, the outriggers are no match for the impressive 15,940 psi compressive strength of Grasspave2.

The ladder is extended with the outriggers engaged.

The Grasspave2 grass fire lane extends around the hospital.

Even with the outriggers down, the Grasspave2 holds up to the enormous pressure.
