Permeable concrete is an important cost-effective sustainable urban drainage system that can reduce storm-water run-off to alleviate the problem of localized urban flooding and potentially reduce the investment cost of underground sewers.
The Distrikt will use this type of concrete in road construction for the device filtration zones. This will allow the removal of water from the carriageway, especially in places where there is no storm sewer. Infiltration of water flows through concrete pavement coatings contributes to their rapid removal from the surface.
The key environmental benefits of permeable concrete pavement are related to stormwater runoff reduction, underground water quality improvement, heat-island effect mitigation, traffic noise reduction, and skid resistance improvement.
Permeable concrete is well suited to urban areas that lack conventional storm-water management facilities. In new urban areas, they can decrease development costs by limiting the need for other storm-water management infrastructure.
Solutions Provided by Permeable Concrete
Permeable concrete is one of the most advanced concrete solutions and. A permeable solution has several advantages over traditional solutions.
- Surface water can freely drain through a permeable concrete-based permeable solution, reducing runoff and the risk of flooding. Its higher permeability allows for a higher flow rate, lowering the risk of clogging.
- Permeable concrete has a light color and reduced density compared to asphalt and conventional concrete which results in a positive effect on the heat island effect. Permeable concrete reflects more solar energy than it stores and emits as heat energy, which contributes to rising temperatures.
- Permeable concrete is effective at removing pollutants from stormwater that will greatly increase water quality.
- Permeable concrete pavement is ideal for protecting trees in paved environments. Permeable concrete pavement allows more air and water for trees to be obtained.
