Super-Permeable Concrete Drains 4000 Liters of Water in 60 Seconds

Water logging is a major issue in most parts of the world when you have no means to drain the excess water; it can leave home and streets flooding with water. However, all that may be the thing of the past because topmix Permeable has just the right solution to prevent water from remaining stagnant on the surface. The company has created a super concrete that has a [permeability rate of 36,000 mm/hour. If that doesn’t amaze you, nothing will. It helps to drain the water rapidly from the surfaces such as parking surface, streets, walkways and driveways when it rains heavily. The company claims their invention is so robust; one has to see their video believe it.

However, some of the frequently asked questions about their product is the utility of the concrete in the frigid temperatures. Also, many web users were curious what would happen if the dirt blocks the permeability of the concrete in due time and the susceptibility of the material to collapsing and opening into a sink hole.

Here is the company’s response.

Will The Pavement Not Crack At Frigid Temperature?

The concrete offers structural stability at varying temperature despite offering ideal permeability. The product was designing bearing in mind the contributing factors such as the permeability to allow idea draining on the event of a storm

The company assured the curious askers that the water wouldn’t sit within the permeable substance and would rather drain below as the storage layer will have an aggregate of 30-40%. Hence, if the water froze within the layer, it wouldn’t compromise the draining potential significantly.

Wouldn’t The Pavement Be Blocked Over Time Due To Dirt And Remain Unusable?

Topmix claims with an average permeability of 36,000mm/hour; it would take an impractical amount of dirt at any point in time to cause failure in the system’s functioning. As the average practical permeability needed is 300mm/hour to deal with a 100-year-old storm despite the fact that permeability could vary depending on local climate conditions. Topmix claims even if there is 95% block, the area will still allow a considerable amount of water.

What About Risks Of Sinkholes?

Sinkholes are caused when the rock beneath gives way due to the acidic water and are a caused by Karst process. Hence, the company assured there won’t be such risks considering the fact that SuDS design is implemented, and a ground investigation is conducted prior to paving or application of concrete.
