Earth construction workshop with the participation of Raiz Arquitectura from Mexico, with architect Karen Poulain expert of the tapial (rammed earth) technique, where we were able to study all the details necessary to apply this type of wall construction, building scale samples and a bench that will remain as a memory of this experience in a magical place in Quebradas de Perez Zeledon. In addition, a bahareque (wattle and daub) wall was built using the traditional technique and bamboo for its structure. More than 30 people participated in this workshop where we shared experiences with other professionals, builders, members of the community and the Las Quebradas Biological Center.
