With the rise in the price of raw materials over the last few years, the pressure to use alternative building materials that are profitable and at the same time contribute to sustainability has increased. Straw, bamboo, hemp and tadelakt are some of the new materials that have been replacing traditional building materials such as concrete.
Hemp
Hemp cement has the same durability and insulating properties as traditional concrete. Hemp is a crop that requires little water, contributing to more sustainable large-scale production. Hemp bricks are another increasingly popular product, suitable for masonry work and considered 100% sustainable and natural.
Bamboo
Bamboo is a fast-growing wood compared to other traditional woods and is elastic, light and very resistant. Many companies are working on developing processes to improve the characteristics of bamboo and thus extend its useful life.
Reinforced Concrete
Carbon fiber reinforced concrete reduces the amount of cement needed to provide a strong structure. Although carbon is not sustainable, reinforced concrete leads to significant cement savings of up to 80%, increasing the efficiency and sustainability of its production.
Straw
Straw is also an insulating, biodegradable material with a near-zero ecological footprint. Its ease of access, application and longevity when stored in low humidity conditions has led to an exponential growth in demand.
Tadelakt
Finally, tadelakt is a natural, decorative and waterproof plaster based on Moroccan lime. This ancient material has only recently become popular. In the environmental sphere, it has the advantage of releasing up to 80% less carbon dioxide than cement. Its surface is smooth, polished and similar to natural stone, making it ideal for use in damp spaces such as shower cubicles and swimming pools.
