Waterproofing mortars play a crucial role in construction by providing effective protection against water infiltration. Composed of cementitious materials, polymers, and additives, these mortars create a robust barrier that prevents water penetration, safeguarding structures from potential damage caused by moisture.

Applied as a coating or admixture, waterproofing mortars are versatile, suitable for various substrates such as concrete, masonry, and even certain types of insulation. Their application extends to basements, roofs, balconies, and other critical areas, reinforcing the structural integrity and longevity of buildings in diverse environmental conditions.
