As an air lime expert, Weber Tradical offers limes that are specifically suited to old buildings — Batidol, Chaubat, Chaubor — and draw on the wealth of our heritage. They come in different formats: powder, wash, paste or granules. We also offer a whole range of Tradical branded products containing a high proportion of air lime — including hempcretes with excellent thermal and hygrothermal properties — that are the result of 20 years of research and experience. All of these safe, quality solutions are an inherent part of our DNA.
