In addition to preventing floods, this pervious concrete is good for the environment. Lafarge Tarmac is dedicated to sustainable construction solutions, 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.
