摘要

PROBLEM TO BE SOLVED: To provide a water retentive paving unit capable of preventing a water retentive block from being broken even when a heavy object such as a vehicle or the like is put on it; a water retentive paving system composed of a plurality of water retentive paving units; and a method for forming water retentive pavement using the water retentive paving units.

SOLUTION: The water retentive paving unit 11 has a water storage vat 3 having an opening part in its upper part, a water permeable cushion layer 5 formed by spreading water permeable cushion materials in the water storage vat 3, and a water retentive blocks 6 spread over the water permeable cushion layer 5.
