Choose a liquid coating for suitable surfaces, a water-swelling product for suitable joints and penetrations, or rapid plugging mortar for active leaks. Each product has a different purpose.
- Identify where the water comes from and whether it is under pressure
- Prepare corners, cracks, joints and penetrations carefully
- Apply the required thickness, backing or reinforcement
For permanent immersion, direct sunlight or water pressure, choose a product whose rated limits match the project conditions.
