Roof Garden Waterproofing

A rooftop garden adds much charm and beauty to your dwelling abode. But few people know the importance of avoiding water damage occurring in your roof gardens and ways to do so. Roof garden waterproofing is rarely given the importance it deserves, but it goes a long way in keeping your terraces and roofs secure, in good shape, and free from disturbing leaks and smelly moulds.

What includes waterproofing the roof garden?

Before putting in pots and plants, it is important to wet the floor, which is usually made of concrete (an RCC substrate). Then a cement-based polymer or acrylic grouting compound is used after all loose concrete is removed from the area. This grouting compound is also known as cement slurry. Why use polymer or acrylic materials? These are not affected by water and help keep moisture and humidity out. Sometimes, an additional protective layer of a mix of cement and sand is also used in a particular ratio.

Another method of roof garden waterproofing is to allow for drainage of water before using any waterproofing compound. Just laying the floor of the roof at an angled slope is sufficient to let the water runoff away from it. But you will still need some material that is impervious to water – like tile or granite, or natural stone – before you allow for the water to flow away. Hence, the use of ceramic, porcelain or stone tile acts as a natural barrier against damage from humidity, moisture, accumulated water, etc.
