Rising damp in walls in buildings is a difficult problem to solve. It may occur in old buildings with no original damp-course or newer buildings where the damp-course was not installed correctly. Rising damp is a widespread problem and is described in different countries as:

Italy: ‘umidità in aumento’

Germany: ‘aufsteigende mauerfeuchtigkeit’

France: ‘humidité ascendente’

Spain: ‘humedad ascendente’

A Modern, Science‑Driven Solution to Rising Damp in Heritage Buildings

For any building conservator working with old structures, rising damp remains a persistent and frustrating problem. Moisture travels upward through masonry and carries damaging salts. It weakens internal structures. It also creates unhealthy indoor environments. For decades, conservators have searched for a solution that is both effective and gentle enough for heritage buildings. Yet the problem has continued to challenge even experienced professionals.

However, recent breakthroughs in silicone emulsion nanotechnology have changed the landscape. These advances now offer practical and long‑lasting treatments. They also protect the integrity of historic materials while delivering modern performance.

Tech‑Dry in Melbourne has led much of this progress. Their researchers developed a specialised silane emulsion that installers can inject directly into masonry. Once inside the wall, the cream releases active silicone molecules. These molecules migrate through the pores of the material. As they cure, they form a durable water‑repellent layer. In turn, this layer acts as a horizontal damp‑course and blocks rising damp at its source.

The application process is simple. Installers drill only small holes along a mortar line, inject the cream, and allow it to diffuse naturally through the wall. Because the formulation contains no solvents and produces very low odour, it avoids contaminating indoor spaces and supports safer, more environmentally responsible restoration practices.

This technology offers a practical, accessible alternative to the invasive methods once required to control rising damp, such as wall demolition or full reconstruction. It also empowers homeowners and tradespeople, not just specialists, to treat rising damp effectively.
