Concrete Liquid Waterproof (WP300)
Waterproofing Additive for Concrete
A liquid additive with lubricating properties and reduced permeability, designed for waterproofing.
The Concrete Liquid Waterproofing Additive is a formulated combination of plasticizers, water-resistant resins, and hydrophobic compounds, intended for waterproofing and making concrete, masonry mortars, and grouts impermeable. When added to concrete, it disperses quickly in water due to its plasticizer content and acts as a powerful dispersing agent, causing cement particles that tend to clump together to spread, creating a larger surface area. This allows water to act more efficiently, reducing the amount of water needed for hydration, which decreases water consumption by over 10%. The result is denser concrete with lower permeability. Furthermore, the use of this additive enhances the concrete’s homogeneity, filling voids between aggregates, leading to a more cohesive mix. The presence of water-resistant resins increases particle adhesion and reduces permeability, thereby improving durability and ensuring the waterproofing effect is maintained over the structure’s lifespan.
This product is available in both liquid and powder forms. The liquid form is specifically designed for waterproofing and rendering concrete surfaces and grout impermeable.
Mechanism of Action of Concrete Liquid Waterproofing Additive
How does the Concrete Liquid Waterproofing Additive work?
One of the main ingredients in Concrete Liquid Waterproofing is a plasticizer based on lignosulfonate. When added to the mix, the polar ends of the plasticizer molecules attach to the cement particles, preventing them from clumping together. This prevents agglomeration and increases the workability of the mix, ensuring efficient particle dispersion, which leads to increased concrete density and reduced permeability. Additionally, the resins in the formula improve the adhesion properties, further reducing permeability.

Standard Consumption of Concrete Liquid Waterproofing Additive
How much Concrete Liquid Waterproofing Additive should be used?
The exact amount of Concrete Liquid Waterproofing to be used is determined through precise field testing and depends on the specific materials used in the mix. Typically, for large-volume waterproofing, the dosage ranges from 2% to 2.5% of the weight of the cement. Be cautious: excessive use (up to twice the standard amount) can delay the initial set time of the concrete, though it generally does not affect the final strength and may even increase it. Additionally, it can significantly improve the workability of the mix.
How to Use Concrete Liquid Waterproofing Additive
- The required amount of Concrete Liquid Waterproofing should be mixed with twice the volume of the water used for the concrete mix. Gradually add the diluted additive to the concrete during mixing.
- The additive can also be added to the ready-mix concrete and mixed thoroughly before pouring. It is recommended that mixing last at least 1 minute per cubic meter of concrete.
- The additive can be added during the production of concrete in a batching plant or truck mixer.
