Which products do we utilise ?


At Hydrotec, we usually work with our own products, those from the Hydrothan range.

Hydrothan as a trademark. The Hydrothan products have been applied for almost 25 years in thousands of worksites in Belgium, Luxembourg, France and Spain.

Hydrothan products enjoy UBatc, Cstc or Veritas certificates of approval for Belgium and Cebtp and Lebel Vert Excell for France.

Ecology and durable development

Hydrotec participates in durable development.
After testing several products in aqueous phase for the treatment of rising damp, we arrived at a solution which combines the effectiveness, durability of a treatment offering a 30-year guarantee while protecting the ecology and the health of all residents and workers. In the treatment of rising damp, we recommend the use of Hdrothan10éco, a micro-emulsion of resins totally without hydrocarbons, odourless and non-toxic (Excell Green Label).

Nearly all products bearing the Hydrothan trademark are formulated in aqueous phase:

Hydrothan 10éco for the treatment of rising damp,
Hydrothan 105 for the treatment of humidity in façades,
Basilit B85 for the treatment of la dry rot,
Basilit Curattack for the treatment of the wood insects,
