We are technical specialists in rammed earth architecture and accredited consultants in eco-innovation, product design and technological development.
We work with users, technicians and manufacturers from the very first stages of the project to find the solution that best suits their needs.
At Fetdeterra we promote the use of local material and human resources for sustainable, ecological and environmentally friendly construction. 100% recyclable materials with a low economic and energy cost, which enables constructing healthy and efficient habitats.
As accredited consultants in eco-innovation, we work in various areas of research, searching for new products and building systems with earth. We study the properties of the materials and the optimal composition for obtaining maximum benefits, while we open the way for their standardisation and adaptation to current legislation as members of the Technical Committee UNE-CTN 41/SC 10.
