# Flood-Alleviating Cement This Eco-Friendly Pervious Concrete Reduces Strain on Local Drainage By Alyson Wyers | Published 2015-10-29 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/pervious-concrete References: [springwise](http://www.springwise.com/porous-concrete-helps-prevent-flooding/) & [tarmac](http://www.tarmac.com/) In addition to [preventing floods](https://www.trendhunter.com/trends/cf-mller), this pervious concrete is good for the environment. [Lafarge Tarmac](https://www.trendhunter.com/trends/lafarge-africa-plc) is dedicated to [sustainable construction solutions](https://www.trendhunter.com/trends/studios-workac-and-ignacio-urquiza-architects), which includes a porous cement that reduces the risks of floods. This is especially relevant in heavy rainfall, where impermeable surfaces increase pressure on local drain systems, which can result in a variety of health and safety concerns. This eco-friendly pervious concrete acts as a filter for pollutants that would normally be in water run-off. Topmix Permeable concrete enables rain water to drain through the underlying water table. The material has 35% more void space compared to traditional concrete. Topmix Permeable is perfect for pedestrian areas where localized floods could occur -- from parking lots to cyclist paths and residential areas. In the future the product could also provide a city cooling solution. ## Trend Insights (Trend Hunter) - Score: 4.6/10 - Popularity: 82% | Activity: 49% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### What Makes This Trend Stand Out - **Eco-friendly Cement:** Opportunity to develop sustainable construction products that reduce strain on local drainage and filter pollutants from water runoff. - **Porous Concrete:** Opportunity to develop new construction materials that enable water to drain through underlying water tables and prevent localized floods. - **City Cooling Solutions:** Opportunity to explore ways in which pervious concrete could provide a cooling solution for urban areas in addition to reducing flood risks. ### Sectors Adopting This - **Construction:** Opportunity for construction companies to develop and market sustainable, eco-friendly, and flood-reducing products. - **Urban Planning:** Opportunity for urban planners to incorporate materials like Topmix Permeable in their designs to reduce flood risk, pollution, and provide city cooling solutions. - **Environmental Services:** Opportunity for businesses specializing in environmental services to expand into the development and production of eco-friendly construction materials that reduce flood risks and pollution. ## Related on Trend Hunter - [Bio-Cement Oceanic Structures](https://www.trendhunter.com/trends/reef-rocket.md) - [Weather-Resistant Hexagonal Tiles](https://www.trendhunter.com/trends/asak-flyt.md) - [Flexible Concrete Water Tanks](https://www.trendhunter.com/trends/inflatable-concrete-tanks.md) - [Flood-Smart Basketball Courts](https://www.trendhunter.com/trends/grain-collective.md) - [Carbon-Negative Artificial Sand](https://www.trendhunter.com/trends/artificial-sand.md) - [Resilient Concrete Sea Walls](https://www.trendhunter.com/trends/breathing-sea-wall.md) - [Shrimp Cell-Fused Cements](https://www.trendhunter.com/trends/shrimp-cell-fused-cement.md) - [Low-Carbon Biomaterial Bricks](https://www.trendhunter.com/trends/cob-brick.md) - [Underwater Concrete Printing Systems](https://www.trendhunter.com/trends/darpa-1.md)
