The reason why colored sand maintains its paving function even after more than 15 years.

Introducing technical information about permeable and water-retaining blast furnace slag pavement "Color Sand"!

We will explain the reasons why the "permeable and water-retaining blast furnace slag pavement (color sand)" has maintained its paving functionality even after more than 15 years since installation. Color sand meets all five "pavement requirements" expected for pedestrian areas and maintains high performance among pedestrian pavements. The characteristic of the blast furnace water-quenched slag used as aggregate, "latent hydraulicity," not only enhances strength but also provides excellent permeability and water retention due to its porous structure. Furthermore, to prevent the deterioration of the pavement surface, it releases pressure caused by the volume expansion of moisture during freezing, which occurs due to repeated freeze-thaw cycles in winter.
