quality management and laboratory
All production processes are constantly monitored and controlled by external and internal sampling. In the Hawita central laboratory in Lauterbach, qualified specialists with the latest technical equipment analyse the raw materials, aggregates used, the finished mixtures as well as samples from the culture and the irrigation water of the customers. More than 10,000 samples are taken every year, which are stored for two years as reserve samples after examination in the company’s own sample room. The result of these extensive efforts is our consistently high quality and, last but not least, the award of the RAL quality mark for our soils and substrates.
