DEFIX PROSEAL PI-1 Concrete Waterproofing Coating – An Effective Waterproofing Solution for All Concrete Structures

Many investors and construction units believe that once concrete hardens, it is dense enough to prevent water ingress. However, in reality, there are always microscopic pores and capillary systems within the concrete. These are the pathways for water, moisture, and corrosive agents to penetrate, causing leaks, cracks, peeling of the finished layer, and reducing the lifespan of the structure.

Especially in areas frequently exposed to water such as rooftops, basements, water tanks, wastewater treatment tanks, restrooms, foundations, or underground walls, without a specialized waterproofing solution, the structure will show numerous signs of deterioration after only a short period.

That's why DEFIX PROSEAL PI-1 was researched to create a durable concrete waterproofing coating, helping to prevent water from penetrating deep into the structure and extending the lifespan of the building.

What is DEFIX PROSEAL PI-1?

DEFIX PROSEAL PI-1 is a grey powder concrete waterproofing coating, utilizing a silane-based crystalline waterproofing system combined with polyvinyl alcohol binder on a cementitious active ingredient base. After mixing with water in the correct ratio, the product forms a mixture that can be applied with a brush, roller, or spray gun on various concrete surfaces.

In addition to creating an external waterproof layer, PI-1 also helps detect and seal pores and capillaries within the concrete, minimizing the penetration of water and moisture into the structure.

Outstanding Advantages of DEFIX PROSEAL PI-1

Compared to many conventional waterproofing solutions, DEFIX PROSEAL PI-1 offers numerous superior benefits:

Effective water resistance according to BS EN 14891 standard.
Good adhesion on dense concrete surfaces.
Easy to mix and apply.
Can be applied with a brush, roller, or spray gun.
Suitable for both civil and industrial constructions.
Helps increase durability and extend the lifespan of concrete structures.
Does not require overly complex application procedures, saving time and labor.

Thanks to its ability to create a continuous protective layer on the surface, PI-1 helps reduce the risk of water penetration, limits the growth of mold and other agents that cause structural damage.

Applications of DEFIX PROSEAL PI-1

DEFIX PROSEAL PI-1 is designed for various long-term waterproofing applications such as:

Concrete rooftops.
Balconies.
Restrooms.
Concrete walls.
Underground cast walls.
Basements.
Building foundations.
Ponds.
Water tanks.
Wastewater treatment tanks.
Tunnels.
Cement pipes.
Retaining walls.

These are all locations frequently exposed to water or high water pressure, thus requiring a waterproofing system capable of long-term protection.

DEFIX PROSEAL PI-1 Technical Specifications

These specifications ensure the product is suitable for various types of constructions, from small-scale projects to large infrastructure projects.

DEFIX PROSEAL PI-1 Application Instructions

To achieve optimal waterproofing effectiveness, the application process must be followed correctly.

First, the concrete surface must be clean of dust, grease, and other impurities. For highly absorbent surfaces, saturation with water is required, but without standing water.

Next, pour the measured amount of water into the mixing bucket, then gradually add DEFIX PROSEAL PI-1. Use a slow-speed mixer for about 5–8 minutes until the mixture is homogeneous, then let it rest for about 5 minutes before application.

The product can be applied with a roller, brush, or spray gun. It is recommended to apply 3–4 coats to achieve a minimum thickness of approximately 1 mm. The mixed product should be used within 3 hours to ensure quality.

Important Notes for Use

During application, note the following:

Do not mix too dry or too dilute as it will affect the workability and strength of the coating.
For highly absorbent areas or joints with old concrete, reinforce with fiberglass mesh.
In hot weather conditions, cure with water daily for about 7 days.
Do not mix with any other materials than clean water in the instructed ratio.
Apply in temperatures between +5°C and +35°C.

Adhering to technical requirements will help the waterproofing layer achieve maximum durability and effectiveness.
