FAQs on Terracast Walls (with Rammed Earth & Poured Earth)
While Terracast Walls are typically constructed in inorganic shapes due to practicality and cost-effectiveness, it is possible to create organic shapes. However, shaping the walls organically may increase costs, primarily due to the intricate formwork required. This makes inorganic shapes more common in standard construction practices.
Rammed Earth walls offer impressive versatility regarding size. The length of these walls can theoretically be limitless. For load-bearing walls, a typical thickness of around 24cm and a height of 360cm are considered standard. However, non-load-bearing walls can have a reduced thickness, potentially down to 10cm. These dimensions provide a robust and flexible framework for various architectural designs.
Absolutely. Rammed Earth walls can exhibit horizontal lines and layers with varying thickness, providing an opportunity for artistic expression and customization in design. This allows for unique and aesthetically pleasing patterns to be integrated into the structure, adding a distinctive touch to the overall appearance.
Yes, Rammed Earth walls can be designed with curves based on the shape of the formwork used. While this may incur additional costs for special formwork, it provides the opportunity to create unique and visually appealing structures, adding an artistic dimension to the construction.
Terracast walls are constructed using a quality road base material, which is a mixture of soil and gravel stabilised with cement and/or lime. Admixtures are also added to meet specific requirements of projects. This combination enhances the strength and durability of the walls, ensuring longevity and stability in diverse environmental conditions.
Soil for Terracast walls are primarily sourced from the construction site itself or from other locations as close as possible to the site. This approach minimises energy costs associated with transportation, aligning with sustainable practices and reducing the overall environmental impact of the construction process. Materials other than soil are sourced from the local market.
In theory, soil from one's own property can be used for Rammed Earth construction. However, it's essential to consider factors such as soil quality, contaminants, and the need for proper testing. Soil preparation and testing costs should be factored into the decision-making process, ensuring that the chosen soil composition meets the required standards for stability and strength.
Yes, it is possible to use different soils from diverse locations for Rammed Earth construction. However, thorough testing and analysis of soil samples are crucial. Soil testing ensures that the chosen composition meets the required standards for stability and strength, providing a reliable foundation for the construction process.
All plumbing and electrical points are strategically positioned internally during the construction of the walls. This approach ensures a seamless and integrated system within the walls, preserving the natural appearance while meeting the functional requirements of modern infrastructure.
Fixing shelves on Rammed Earth walls is easily achievable using masonry wall fasteners. Pictures can be hung using nails, providing flexibility in design and eliminating the need to locate wall studs. This adaptability simplifies the process of personalising and decorating spaces adorned with Rammed Earth walls.
In normal case, no additional finishing is required on the walls. For internal applications, a clear water-based sealant can be applied if required. Externally, waterproof additives can be included in the mix if required, resulting in a finished product that combines natural aesthetics with structural integrity.
Rammed Earth homes exhibit energy efficiency due to well-designed passive solar features combined with the high thermal mass of the walls. This combination allows the walls to naturally store energy, creating a stable internal temperature. The energy-efficient design reduces the need for active heating and cooling systems, contributing to sustainable and eco-friendly living.
Rammed Earth walls are non-combustible, boasting a fire rating of upto 4 hours. These walls are among the select few building materials recognized for high-risk fire areas. The fire-resistant nature of Rammed Earth provides a reliable and safe construction option for properties in regions prone to wildfires.
Due to the construction materials and methods employed, Terracast Walls are termite-resistant.
Rammed Earth walls have a rich history dating back over 6000 years, with notable examples such as the Great Wall of China and the Pyramids of Egypt standing as testaments to their longevity. With proper construction and maintenance, Rammed Earth walls have the potential to endure for centuries, showcasing the enduring strength and durability of this time-tested construction method.
Rammed Earth & Poured Earth walls can withstand water impact if a damp-proof course is applied beneath and a waterproof coating is on the surface. Sunlight primarily affects the life of coatings, not the structural integrity. Daily cleaning doesn't harm the walls, especially when a clear waterproof coating is present. Properly treated, Rammed Earth & Poured Earth walls exhibit resilience against environmental elements.
We provide tailored quotes based on the unique specifications of each project, ensuring transparency and alignment with client expectations. Various factors like wall characteristics, thermal mass requirements, aesthetic preferences, and design flexibility influence the overall cost.
Maintenance for Terracast walls is generally straightforward. The frequency and cost depend on factors like usage and climate exposure. Typically, cleaning and applying a clear coat every 4 to 5 years is recommended. This process helps preserve the aesthetics and structural integrity of the walls, ensuring a durable and visually appealing outcome.
