Geoplast products that improve urban resilience
2 May 2019
Around 40 million people in the world are under constant flooding risk in coastal cities. Floodings are consequences of sea level rise, hurricanes, high tides, groundwater rise, or extreme precipitation. So far, the most challenged world countries and cities have been:
- China – Shanghai, Guangzhou, Shenzhen,
- India – Kolkata, Mumbai, Dhaka,
- USA – New York, Miami, Key West, Cape Hatteras, Tampa, New Orleans,
- Southeast Asia – Ho Chi Mihn, Bangkok,
- Japan – Tokyo, Nagoya.
Endangered areas are urged to increase their resilience. Predictions regarding climate change–related disasters listed for next decades are:
- By 2030, the number of annual high tide floods will triple on Gulf and the east coast of the USA,
- By 2070 around 150 million people in the world will be under flooding risk.
Following products can significantly increase the resilience of endangered areas:
- Provide mechanically and seismically resistant structures,
- Suitable for fast-building of homes and shelters.
- Create underground basins in public areas like parking lots or parks,
- Irrigate, accumulate, drain, and dispose the rain- or wastewater,
- Prevent flooding by slowing down the discharge of rainwater,
- Useful in areas where city sewage infrastructure is missing.
- Creates underground concrete water storage tanks,
- Accumulates rainwater in public areas like parks or parking lots,
- Suitable for household water harvesting and irrigation of green areas,
- Prevents flooding by discharging the rainwater directly into sewage infrastructure.
- Accumulates and drains rainwater by providing high horizontal and vertical flow capacity,
- Suitable for parking lots and pedestrian areas.
- Used to raise foundations of houses in areas under high flooding risk,
- Provides stabilization to a building.
- Protects the insulation of foundation walls and ventilates them.
- Eliminates rising damp in walls and foundations.
- Increase the urban green surfaces when used for green roofs’ coverage,
- Decrease the heat-island effect by decreasing the local temperature,
- Capture and regulate the run-off of rainwater on green roofs.
- Regulate thermic insulation of the building,
- Decrease the amount of CO2 in the air.
- Protect grass and its roots when used for green driveable and walkable areas,
- Increase green surface on the urban level,
- Provide drainage of green areas.
- Lowers local temperature when used on façade walls,
- Decreases the heat-island effect.
