A base block that exhibits ultra water retention performance due to a super-micro porous ceramic material.

Prevents road surface flooding during heavy rain and suppresses road surface temperature rise during hot weather. Green Biz G-tt is a base material for interlocking block products. Its aggregate is made from a ceramic material with an ultra-microporous structure, providing excellent water retention and permeability. During sudden heavy rainstorms that hit urban areas, it quickly absorbs rainwater that falls on the road surface, helping to prevent flooding. Additionally, during dry periods, it absorbs and retains moisture from beneath the pavement, demonstrating a cooling effect through evaporative cooling. It is an environmentally functional block that maintains urban comfort while controlling water.
