There are three types of Grasscrete. Each type has different dimensions, paving depth, reinforcement and load bearing capacity.
The three types are:
As mentioned above, each grasscrete type has a different load-bearing capacity, that is the maximum vehicle weight that can travel over the Grasscrete.
Here is a table specifying what the maximum vehicle weight, in accordance with its respective Grasscrete type:
