Several counter measures have been carried out for mitigating heat island effect. One of those is installing on top of the roof with base materials having planted vegetation. The base materials are required good water absorption and retention which is necessary for the plant to survive. Therefore, in this study, we investigate the relationship between water absorption and water retention within the pore structures of porous ceramics. The raw materials of the ceramics were used waste resources. The structures were changed by different state foaming additive. It was found that the water absorption was dependent on open porosity and the pore size. The water retention, was reduced excessively with high porosity. Accordingly, the control of pore structure is described in details in this study.
