Meet our teamOur values
Innovation
Continuous development based on materials science findings and practical experience in building renovation.
Sustainability
Long-lasting waterproofing solutions that preserve the building fabric rather than merely concealing moisture problems temporarily.
Partnership
Close cooperation with trained and certified specialist contractors who take responsibility for planning, execution and quality.
Lastingly dry masonry.
With tested waterproofing technology.
wetBLOC was developed to provide a lasting solution to one of the main challenges in existing buildings: moisture in masonry. The aim is to limit capillary moisture transport permanently, protect the building fabric and preserve the long-term usability of buildings. The technology is particularly suited to existing, older and heritage-listed buildings.
Rotia International GmbH is the system provider for wetBLOC technology and is responsible for distribution, international market development, building the partner network, training and quality assurance.
Remediation work is mainly carried out by trained, legally independent specialist partners and is supported or taken on by Rotia International where necessary.
International distribution is organised through national distributors and regional support partners. For technical questions, remediation projects or potential cooperation, please contact us using the contact form.
