Cellar Waterproofing and Renovation

This 15^th century listed manor house had a cellar, primarily used for storage.

At some point in the past, the dampness problem has been attempted to be resolved using a modern cement-based tanking slurry which lasted a few years, eventually starting to blow due to the combined effect of humidity and salts.

Recent measurements have revealed lots of hygroscopic crystallizing salts - the main reason behind the blown and crumbling bricks. There was an especially high content of chlorides present as in the past the cellar most likely has been used for preserving and storing meat.

To renovate the cellar in a building friendly way, traditional Roman lime materials have been used, that are capable of dealing with high moisture, salt crystallization and condensation easily, providing a sympathetic solution that can last for decades - much longer than modern cement materials.

To highlight some of the changes: here is the stair area before and after the renovation. The crumbling is gone and we can see the natural colour of the second coat - a pleasant heritage brick colour. However, if needed, a white or coloured lime finish can also easily be applied on top for a different looks.

Here is a photo gallery of the project showing more details.
