Mapei Mapelastic: Professional Waterproofing Solution for Balconies, Terraces, and Swimming Pools
Water is one of the most significant factors that can gradually reduce the durability of buildings. It can cause deterioration of concrete surfaces, blistering of floor finishes, and corrosion of reinforcement bars. For this reason, waterproofing is not merely an aesthetic consideration but a critical technical requirement that directly impacts the lifespan of a structure.
Although many waterproofing products are available on the market, not all offer the same level of performance. One of the most trusted solutions is Mapei Mapelastic, a professional waterproofing system that has been used worldwide for more than 30 years. It delivers reliable protection in balconies, terraces, bathrooms, swimming pools, and other moisture-exposed areas.

Mapelastic is a two-component, cement-based waterproofing mortar with high elasticity. Its flexible structure allows it to accommodate substrate movements and helps maintain waterproof protection even in the presence of minor cracks.
In addition to creating a waterproof barrier, Mapelastic protects concrete surfaces against carbonation (CO₂ penetration) and offers excellent UV resistance, making it suitable for long-term outdoor applications.
