Natural plasters and finishes are eco-friendly. They are made mostly of materials directly available in nature and which require little or no energy for their processing. They are therefore more healthy.
Lime is obtained by firing limestone. It is a traditional material produced all around rural India and can be used as a replacement of cement to obtain waterproof plasters. Lime based finishes are also suitable for external walls as well as internal spaces that are humid, such as kitchens and bathrooms.
Stone dust is the replacement to river sand in traditional plasters. Unlike river sand that is mined from ecologically sensitive areas, stone/quarry dust is crushed and powdered granite chips, a byproduct of the stone mining industry. It is an aggregate within the plaster mix and provides it’s skeletal structure. The particle size of the stone dust can be graded and allows us to control the thickness and texture of the plasters.
The materials that we use in the making of our interior spaces have a big impact on the quality of the air that we breathe. A lot of materials that are used regularly in our buildings such as paints, varnishes, glue, laminates, etc release volatile organic compounds (VOC) into the space. Continuous exposure to such compounds will have an ill-effect on our health, and most certainly, on the health of the people involved in the construction and making of the building. The use of natural plasters eliminates exposure to VOC. In fact, they have a positive impact on the air since they help in the regulation of humidity, temperature.
Lime based plasters have the natural ability to absorb this excess of humidity in the air. This moisture is captured and released when there is less humidity in the room during its usage cycle. This property is also believed to enable the plaster to remove certain odours from the air within our homes.
Designing a waterproof wall with a 10-year guarantee involves both material choices and proper construction techniques to ensure durability and long-lasting performance. Here's a comprehensive guide for creating such a design: 1. Material Selection The key to waterproofing lies in selecting high-quality materials that are resistant to water penetration and weathering over time. Some essential materials are: Waterproof Concrete: Use concrete mixes that have water-repellent additives or low-permeability concrete. This is ideal for retaining walls and basements. Waterproof Membrane: Apply waterproof membranes (bituminous, liquid-applied, or sheet membranes) on the surface to form a barrier against water.
A concrete structure refers to any type of building, bridge, or infrastructure that is made primarily from concrete. Concrete is a composite material consisting of cement (usually Portland cement), aggregates like sand and gravel, and water, which hardens over time. It’s one of the most widely used materials in construction due to its durability, versatility, and relatively low cost. Key Features of Concrete Structures: Strength and Durability: Concrete is known for its compressive strength and ability to withstand significant loads without deformation. When reinforced with steel (rebar), its tensile strength improves, making it suitable for complex structures like skyscrapers and bridges. Versatility: Concrete can be molded into various shapes and sizes, making it suitable for different architectural designs and structural requirements. It is used in beams, slabs, foundations, walls, and columns.
