7 Sustainable Construction Materials



Concrete, wood and bricks… these are just some of the traditional building materials we’re used to seeing. However, sustainable construction materials are becoming increasingly popular alternatives today. More companies and individuals are selecting sustainable materials for their kinder environmental footprint. They can be renewed at much faster rate than non-sustainable materials. Take a look:


Bamboo is a lightweight material that is strong and can regrow faster than trees. Considered one of the best eco-friendly building materials, bamboo has a high strength-to-weight ratio, even greater comprehensive strength than concrete and brick, and lasts a long time. Bamboo is most often used for flooring.


Straw bales are a smart, sustainable way to insulate walls without using concrete, plaster or regular insulation. When straw bales are placed inside walls, they create excellent insulation that keeps indoor temperatures consistent.


Cork offers superior insulation, and even solid soundproofing, and can help keep energy bills down. Due to its flexible nature, cork reverts to its original shape even after enduring sustaining pressure. Because of this and its resistance to wear, cork is typically used in floor tiles and walls.


Reclaimed wood is an environmentally responsible way to save trees and reduce the amount of lumber in landfills. It’s a great choice for structural framing, cabinetry and flooring and can be found in retired barns, excavation companies, home remodeling contractors and companies, salvage yards, and shipping crates and pallets.


Recycled steel significantly reduces the ecological impact of new construction. Highly sought after by builders, recycled steel can come from buildings, homes or even junk cars. Steel is frequently used instead of wood in the framing process, increasing the durability of a structure against high winds and even earthquakes.

Terrazzo is a mosaic style of flooring in which small pieces of mixed marble scraps, granite and recycled glass chips are set in polished concrete or epoxy resin. Building with terrazzo is a great way to keep indoor air quality clean with durable, eco-friendly and low-maintenance flooring.


Timbercrete is comprised of both concrete and sawdust and can be formed into blocks, bricks and pavers. Its versatility means it can be used for nearly any project that would normally require concrete. Timbercrete is considered sustainable since it takes much less material to produce than concrete, which ultimately reduces waste and environmental impact.
