Whether you're a builder looking to improve your impervious cover issues, or a consumer wanting to prevent water pooling on your driveway, there is a solution! Tarmac's new Topmix permeable!!! Watch the video below to see for yourself how water is able to slip through the cracks and soak into the ground rather than pool and cause flooding. We are all aware of the many drainage issues we face in Austin with our rocky soil. This concrete could help curb flooding in many areas and future homesites.

Since the water drains throught the permeable concrete layer, this product can withstand Austin's occasional freeze. The water doesn't sit where the concrete is laid and thus won't crack it. It's also ok to have normal amounts of dirt and that won't affect the drainage of the water as the dirt will naturally filter through the concrete over time. In order for floodwaters to drain, there needs to be a permeability rate of 300mm/hr for a 100 year flood. This product has a rate of 36,000 mm/hr so you can see that even over time and with dirt, proper drainage will occur.
