Title: Floor plate for forming a foot path and method of laying a walking surface on a roof

Abstract: Walkable foot plates are laid directly on a concrete slab or a water resistant layer on a roof. Each foot plate has crack inducing grooves which divide the plate into blocks which are connected to each other by weak joint portions defined by the grooves. The foot plate cracks along the grooves to be accommodated to uneven surface portions of the slab or layer. Flexible reinforcing material extends across the weak joint portions to maintain the blocks connected to each other after the weak joint portions are cracked.
