Watertight solutions from natural materials

Dantonit’s response to increasing environmental problems is solutions featuring raw bentonite, where neither chemicals nor additives have been used to achieve high density. Bentonite is a special type of clay – a natural material – that absorbs water, meaning that it remains completely sealed. The material is therefore ideal for use in solutions to prevent pollution and seepage, and also to protect areas against cloudbursts, for example. Bentonite does not deteriorate and has a self-repairing property, which makes our products extremely durable and long-lasting.
