Innovative construction materials that preserve the environment

With the rise of environmental awareness and the need to reduce ecological impacts, the demand for construction projects that embrace the sustainable concept has increased. In addition, standards and certifications such as LEED (Leadership in Energy and Environmental Design) and AQUA-HQE encourage the use of environmentally friendly practices and materials, making the use of sustainable materials in projects almost indispensable.

Bioconcrete

Bioconcrete is a revolutionary innovation in civil construction, resulting from the combination of traditional concrete with colonies of Bacillus pseudofirmus bacteria. These extremophile microorganisms are capable of surviving for more than 200 years under adverse conditions. Thus, bioconcrete has the ability to self-repair: when water infiltrates cracks, the bacteria are activated and metabolize nutrients present in the mixture (such as calcium lactate), producing limestone as a byproduct and naturally sealing the fissures.

In this way, the material not only extends its own lifespan but also drastically reduces the need for repairs, saving labor and long-term maintenance costs. Its applications range from urban infrastructure to projects in hard-to-reach locations.

Eco-friendly Paints

Eco-friendly paints, also known as sustainable paints, are produced from natural elements or materials with low environmental impact. Unlike synthetic paints, which contain harsh chemical compounds such as solvents and heavy metals, eco-friendly versions use renewable and biodegradable raw materials. Many of them are water-based and may include clay, corn starch, and plant-based adhesives, ensuring a less toxic composition that is safer for human health and the ecosystem.  

As for color, it can be obtained through natural pigments extracted from flowers, fruits, seeds, and even minerals. In addition, many of these paints are free of volatile organic compounds (VOCs), which are harmful to indoor air quality and contribute to atmospheric pollution.

Gypsum Brick

Gypsum brick is produced by molding raw gypsum into forms that reproduce textures and grooves, imitating the rustic charm of conventional brick. Ideal for indoor and dry environments such as living rooms, bedrooms, and offices, this cladding adds beauty and personality to the space, with the advantage of being more affordable in both material and labor when compared to other ceramic or stone cladding options.

Eco-friendly Roof Tile

The manufacturing of eco-friendly roof tiles prioritizes the use of renewable and recycled resources, such as Tetra Pak packaging, PET bottles, and even natural fibers like certified wood, sisal, and coconut. Eco-friendly tiles stand out for their durability, light weight, and resistance to weather conditions, making them an excellent alternative to conventional tiles. They can be used in various types of roofing, from homes and industrial warehouses to construction sites and temporary shelters.

Some models offer thermal and acoustic insulation, increasing the comfort of indoor environments. Installation is simple and often requires less support structure, which can reduce costs and speed up construction timelines.

Bioplastic

Bioplastic is produced from renewable and biodegradable raw materials such as corn starch, sugarcane, and cellulose. Unlike synthetic plastics derived from petroleum, this sustainable material decomposes much faster in the environment, significantly reducing its impact on ecosystems and helping to decrease plastic pollution.

In civil construction, bioplastic has been used in the production of flooring, baseboards, and partition walls, offering resistance and durability. In addition, recent research explores its use in roof tiles, cladding, and even temporary structures.

Calfetice

Calfetice is a traditional mixture composed of clay, lime, cement, and plant fibers, widely used in Colombia to coat the walls and ceilings of bamboo or wooden structures. In addition to being an economical and eco-friendly alternative, the material is known for its chromatic versatility, as it can be pigmented with various natural powders. The plant fibers not only reinforce the structure—reducing the need for excessive cement—but also provide greater flexibility and durability to the coating.
