Salt - Saltpeter

Salt spreads slowly

Dampness transports salts

In this old building salts destroy mortar

Such layers of salt damage masonwork

Salts are a huge damage source to most buildings!
- All soil contains moisture and every masonwork is a transport route for it. This moisture doesn't cause as much damages as the salt which is led into the masonwork.
- Every building material contains salt. Capillary rising damp helps to spread the salt up to the masonworks surface. There the damp will evaporate and what's left is nothing but salt also known as saltpeter.
- Salt / saltpeter changes its condition depending on temperature and air humidity. It can change into liquid or crystalline. These perennial crystals are able to damage plaster, paint, tiles or whole parts of building material.
- Salt / saltpeter needs dampness to be transported from the inside to the walls surface. So if the masonwork gets dried the capillary rising damp and the salt transport will be stopped!
The salt needs to be removed from your basement. Salt works hygrophile: it attracts moisture, especially in summer when warm and damp air comes into the basement. Now the walls get damp and the masonwork becomes soaked directly through water.
Brush off your walls and vacuum the salt from the floor. Now the superficial salt is gone.
