Houses that have been built for decades, started to show the signs for fixing. It is time for the homeowners to renovate. One of the problems is the permeability of concrete. This problem most often occurs in the bathroom or somewhere inside the house. Especially during the rainy season, houses have this leakage or cracked concrete easily. The choice of using waterproof cement is an option to help prevent leaks inside your home. And also help solve the problem of cracked concrete. Waterproof cement is easy to use. Tiles can be placed on the waterproof cement for both interior and exterior parts. It also provides good adhesion, flexibility, and durable to the weather. However, it is not recommended to use on brick surfaces and high porous concrete.

Waterproofing systems are generally divided as follows:

– Additives (Waterproof Admixture) pour down while mixing concrete
– Crystal concrete (Waterproofing by Crystallization) this type of waterproofing has both powder and liquid. When the substance enters the concrete, it is crystallizing the concrete, which makes the concrete becomes denser. It prevents leakage from porosity in concret
