Reinforced concrete walls and floors in swimming pools do not have the property to prevent water leakage. Special points such as water drain holes, water entrances, windows, wall and floor joints in concrete construction are poor in terms of sealing. Also cracks that may occur in the concrete also facilitate water leakage. The ceramics and grouting application to be done on the surface of the pool do not provide water isolation by itself.
Pool chemicals over time can overcome joint fillings in swimming pools. In this case, the ceramic adhesive can not maintain its property over time and starts to peel.
