For the main block, Waikari clay was preferred and given a 'fast tracked' yet sophisticated maturity. Here are some of the milestones in its development
Step one: Complete excavation of the pitch block to a depth of 150 mm
Step two: First layer of clay was compacted with 12-ton roller
Step three: The clay was reinserted into excavated hole it came from
Step four: To build up density a massive amount of rolling (150 hours!) was done with 12-ton roller
Step five: Laser levelling of block in preparation for sewing. Then new grass was sewn!
