System Buildup:

Heavy Duty Fiber Reinforced Cementitious Waterproofing

System Description:

This comprehensive waterproofing system combines a two-component cementitious waterproofing layer with a highly flexible acrylic-based topcoat to deliver unmatched durability and performance. The cementitious layer offers excellent crack-bridging capabilities and can withstand positive water pressure up to 7 bar and negative pressure up to 5 bar, ensuring robust protection against water ingress, freeze-thaw cycles, and carbonation. The acrylic-based topcoat enhances the system with superior UV resistance, weather resistance, and solar reflectance. When reinforced with fibers, it adds extra strength and flexibility, forming a seamless and durable protective membrane. Typical uses include waterproofing basements, bathrooms, swimming pools, terraces, roofs, bridge decks, underpasses, and metal profile roofs, making it ideal for both residential and commercial applications. This system is suitable for substrates such as concrete, masonry, stone, metal sheets, and cement boards​.
