Introduction
Waterproofing is a critical part of any construction project, especially in areas exposed to:
• water penetration
• high humidity
• underground pressure
Among the many waterproofing solutions available today, cementitious waterproofing materials remain one of the most widely used due to their:
• ease of application
• strong adhesion to concrete
• cost-effectiveness
From bathrooms and roofs to basements and water tanks, cementitious waterproofing plays a key role in ensuring long-term durability.
What Is Cementitious Waterproofing?
Cementitious waterproofing is a type of coating made from:
• cement-based materials
• polymers
• additives
It is applied as a slurry or coating directly onto concrete surfaces, forming a waterproof barrier.
