Grasstone™,
made with an open-void, or lattice design
have a flat surface that forms a continuous
pattern of concrete when installed. The
open void allows for on-site infiltration
of stormwater and revegetation. Designs
can use topsoil and grass or aggregates
in the grid openings depending upon desired
effect.
The
concrete grid stone reinforces grassy areas
that are subject to wheeled or vehicular
traffic. Typically an area that undergoes
repeat vehicular traffic will become so compacted
that the permeability of the soil structure
is inhibited to the point
Composition
and Manufacture
Grasstone™ is made from a “no slump” concrete
mix. Made under extreme pressure and high frequency
vibrations, Grasstone™ has a compressive
strength greater than 4000psi, a water
absorption maximum of 7%.
