Mapei's Reinforcing Fabric is a non-woven, polyester fabric designed to strengthen waterproofing membranes and crack-isolation systems. It is typically used in conjunction with Mapei products like AquaDefense or other liquid-applied membranes to enhance their performance in areas prone to movement or cracks, such as corners, wall transitions, and substrate joints. The fabric adds an extra layer of durability and flexibility, ensuring a stronger, more reliable waterproofing or crack-bridging system. Easy to embed into the liquid membrane, Mapei's Reinforcing Fabric helps create a seamless, long-lasting protective barrier, especially in demanding areas like showers, balconies, and exterior facades.
