Built on a background of hands-on lime and clay plastering, ECS began a decade ago, focusing on the natural treatment of damp, lime and clay plastering, and spraying cork insulation in southern Spain. Today, BioReforma has taken over the southern operation, and the Asturian team focuses on restricted-access historic restorations, as well as nationwide distribution of natural insulation, low-energy heating, hot water, and solar systems. We try to bridge the gap between historic building restoration and modern NZEB standards, providing the advice and the materials you need to build a healthy, energy-independent structure.
Our whole-house approach begins with a breathable “eco-envelope” made from natural materials such as Diasen solid wall renders, Steico wood fibre, carbon-negative hemp, and clay or lime plasters.
Whether you are restoring a traditional Spanish ruin or building a state-of-the-art new home complete with luxury spa hardware, we ensure your project is flawlessly executed, remains damp-free, is highly efficient, and, if needed, is fully self-sufficient.
Our approach is simple: straight talking, stress-free, and absolutely zero bullshit, using tried-and-tested solutions with over 30 years of experience in very high-end heritage restoration.
