Abstract:

Urbanization has greatly increased the number of impermeable surfaces in Manila. The historic place in Metro Manila, which is Intramuros, has been prone to floods during long and short-lived intense rainfalls. One of the traditionally blamed factors besides the age-old drainage system and clogged streams was the increase in concrete pavements. Permeable concrete has been used around the world to address the problem of flooding and other negative effects such as groundwater pollution and Urban Heat Island. This study conducted several flexural strength tests and falling head tests to assess the flexural strength and permeability of permeable concrete. The data and results from the tests were compared with the data gathered from Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) and Department of Public Works and Highways (DPWH) to determine the efficiency of permeable concrete in reducing the occurrence of flood in Intramuros, Manila.
