PermeaCon(‫ﺑﺮﻣﯿﺎﻛﻮن )ﺧﺮﺳﺎﻧﺔ ﻣﺴﺎﻣﯿﺔ‬Porous concrete paving
PermeaCon is a cast-in-place concrete paving product with water and air permeability and afully pavement-grade load-bearing strength. Rainwater will permeate through PermeaConand down into the soil, thus going back into the environment.
Features The combination of excellent permeability and goodwater retention and infiltration capacity contributes towater management benefits including rainwater outflow
reduction and groundwater conservation.
 The surface temperature of PermeaCon is 5oC to 8oC
lower than that of asphalt pavement. The heat reduction
effect becomes even greater after rainfall with the use of
the latent heat of vaporization of the rainwater, efficiently
alleviating the urban heat island effect.

Rainwater utilization system‫ﻧﻈﺎم اﺳﺘﺨﺪام ﻣﯿﺎه اﻷﻣﻄﺎر‬The combination of a water permeable pavement and a plastic
rainwater retention tank allows efficient rainwater utilization.
To be used as water source during natural disasters. During natural disasters and emergencies
when water service may be disrupted, water retained in the bath can be a valuable water source.
Water can be pumped up directly from the tank to be used for washing hands or flushing toilets.

Features▼ PermeaCon

 Laying PermeaCon, a water-permeable
concrete paving, over the Re-Tansui system allows
efficient collection and retention of rainwater into theRe-Tansui system tank. Rainwater flows into the tankboth from catch basins and directly from thePermeaCon paving above.

 The retained water can be a valuable water
source for household uses during natural disasters
and emergencies and also for greenhouse wateringand other agricultural uses.

Agricultural use
The water retention facility does not require a large concrete tank. It can be buried underground to allow
the land above to be used for other purposes.

SW PermeaPack(‫)ﺧﻠﯿﻂ ﻣﺴﺒﻖ ﺧﺮﺳﺎﻧﺔ اﻟﻄﺮق اﻟﻤﺴﺎﻣﯿﺔ‬‫ﺑﺎرﻣﯿﺎ ﺑﺎك‬SWPorous concrete premix paving product
SW PermeaPack is a premix-type porous concrete paving product optimized forsmall-scale installation and partial pavement repairs and replacements.
Features Only the required amount of product can be prepared for each
installation, significantly eliminating material waste compared tohaving the paving mix supplied from the plant.
 Most of the required ingredients are already mixed into theproduct, which will be ready for use by adding water.
 The product can be installed with simple work tools and thus
allows installation in remote locations without concrete mixing
facilities. Another possible advantage is that installation work
can be flexibly scheduled without worrying about the seasonal
availability of local concrete mixing facilities.
 The overall installation cost is much lower than withconventional paving products.
