MAPEI's Mapefibre synthetic fibers for concrete can reduce or eliminate the need for steel reinforcement, saving time, labor and money on site while achieving superior durability. Micro-synthetic fibers can be added to mitigate plastic shrinkage cracking, while macro-synthetic fibers add tensile strength and flexural toughness in post-cracking conditions.

That's because fiber cement is naturally insect resistant and thus does not rot. So you don't have to add an additional rot-resistant coating and watch out for insect-related damages. Third, fiber cement sidings also resist long-term damage resulting from the sun's ultraviolet rays and humid coastal climates, among others.
