There’s a new type of concrete called “Topmix Permeable” that’s a fast draining concrete pavement solution that rapidly directs stormwater off streets, parking surfaces, driveways and walkway. It’s crazy cool the way it works, watch the video below. Basically it allows water to flow through at a faster rate than ever before. Traditional concrete might let a few gallons of water through to the ground level. This new concrete will let through thousands of gallons of water per hour. Specifically more than 850 gallons of water can pass through to the ground per minute. While the technology for permeable concrete isn’t brand new this is the first time it’s been formulated to withstand the weight of vehicles. It’s also much cooler than traditional asphalt during hot weather. The company behind the innovation, Tarmac, boasts that they use tiny pieces of granite packed together instead of typical sand-based concrete. The UK company has already installed it on car parking lots and golf courses. The company actually offers three different designs based on how much water is allowed to pass through or captured: Full infiltrations passes all water to the soil underneath; Full attenuation captures all the water; Partial infiltration acts as a drainage system to pass water into sewers or waterways. The new concrete works in all places except climates with extreme cold because the water will expand as it freezes and break apart the pieces of the new concrete.
