Limitations
Where judgment is required.
The supporting formation and sub-base carry the traffic; the grid does not compensate for poor construction.
Stationary HGV turning, wheel spin, braking and screwing can damage plastic surface grids.
Use effective edge restraint and control site speed; current CORE guidance recommends 5 mph.
Confirm the current warranty terms on the quotation rather than relying on conflicting published durations.
