Welcome to Dachverband Lehm e.V. - The German Association for Building with Earth
In a time in which environmental responsibility is becoming increasingly important, conservation of resources and environmentally sound construction methods are gaining in significance.
Today there is a demand for building materials which require little energy for their production, which are always recyclable and hygienically safe, and which also offer scope for creative design – modern building materials such as earth.

load-bearing walls, frame construction, monolithic construction, timber-frame construction, restoration of half-timbered buildings, nogging, cob-walling.
Earthen building techniques and construction:
Wall heating, Hypocaust air-heated wall, clay plaster, plaster and render, fine clay render.
Clay and earth are often used in combination with or as a replacement for other building materials incl:
Brick, cement, natural paints, lime, lime render, wood, timber-frame, insulation, tadelakt.
Technical norms and building regulations, books and reference literature:
Lehmbau Regeln, DIN, Lehmbau consumer information, Fachkraft Lehmbau training handbook.
Dachverband Lehm e.V. services include:
Events such as trade fairs, conferences, seminars and workshops; publication of reference material and literature, representation of interests of its members which include architects, planners, consultants, manufacturers, distributors, retailers, and construction firms and companies as well as collating and providing information for all those interested in building with earth.
