Swelling bars are a type of waterproofing material commonly used in construction to seal concrete joints and prevent water infiltration. They are made of a highly absorbent mineral clay called bentonite, which expands when it comes into contact with water and creates a tight seal. Bentonite swell bars are often used in combination with other waterproofing materials such as membranes and coatings to provide additional protection against water damage.
