Our waterproofing solutions

Making buildings smart

Imperbel has evolved from a traditional waterproofing producer into a new international player in ecological, sustainable and energy saving products and services.

The baseline “Making Buildings Smart” reflects our mission and vision : wherever possible make the building “intelligent” so the available resources and energy are used sparingly.
