WHAT IS REVERSE WATERPROOFING? SOLUTION FOR WALLS LEAKING FROM THE OUTSIDE

1. What is Reverse Waterproofing?

Reverse waterproofing is a method of waterproofing from the opposite side of the water source causing the leak, that is, instead of waterproofing on the outside where water penetrates, we treat from the inside where water has seeped in.

This method is extremely effective in cases such as:

- Boundary walls cannot be constructed outside.

- The apartment toilet is leaking from the apartment upstairs.

- Basements, foundations, underground floors, places in direct contact with soil and groundwater.

- The cracks in the wall have been leaking for a long time.

2. When Should We Use Reverse Osmosis Method?

3. Anti-Reverse Osmosis Principle: "Welcoming Water From The Inside Out"

- Water from outside (positive pressure) has seeped into the structure.

- The anti-reverse osmosis material works by penetrating deep into the internal capillaries.

- When exposed to water, the material will swell or crystallize, sealing the pores.

- Prevents water from continuing to seep into the inside of the wall or floor.
