Product Description – Liquid Concrete Waterproofing
Liquid concrete waterproofing admixture is a formulated mixture of lubricants, waterproof resins and hydrophobic compounds that are suitable for waterproofing and impermeability of all types of concrete, masonry mortars and grouts. After being added to concrete, liquid concrete waterproofing, due to the presence of concrete lubricants in its formulation, quickly disperses in water and acts as a strong particle dispersing agent, causing cement particles that tend to clump to disperse and obtain a larger free surface area. In this way, the water in the mixture acts more effectively and the hydration process is carried out with less water and in a more effective manner. This reduces the amount of water consumed by more than 10%, resulting in concrete with higher density and lower permeability. In addition, the fluidization of concrete with the help of liquid concrete waterproofing admixture, due to the proper dispersion of particles in the concrete mixture, fills the empty space between the aggregates and forms a unified and homogeneous mixture. In addition to the lubricating power, due to the presence of waterproof materials in the structure of this material, the adhesion and compaction of the particles are also increased and the permeability is reduced. Also, the use of this product is suitable for concreting in salt marshes and areas containing chlorine and sulfate ions.
Waterproof means that it is a type of waterproofing material that has hydrophobic properties. As mentioned, this product is supplied in liquid form and is completely colorless.
This product is a type of additive that is used to seal concrete and make it impermeable. This product is made from lubricants and inorganic fatty acids and is designed to dissolve quickly in water. Using this product allows cement particles to be better dispersed and produces concrete with higher density and lower permeability. This additive helps to reduce the amount of water used in concrete production.

Standard usage rate of liquid concrete waterproofing
The exact amount of liquid concrete waterproofing used is determined by detailed field tests and according to the materials used in the mix design. However, typically, the amount of liquid concrete waterproofing used for waterproofing bulk concrete is 2 to 2.5 percent of the weight of the cement used. Note that excessive use of this product, up to 2 times the usual amount, can increase the initial setting time of the concrete. The final strength is not reduced by this delay and usually increases. The efficiency of the concrete will also increase significantly.

How to use liquid concrete waterproofing correctly
The amount of liquid concrete waterproofing calculated according to the grade of concrete should be diluted with 2 times the volume of concrete mixing water. The diluted admixture should be gradually added to the concrete during mixing.
- This product can be added to the ready-mixed concrete and after complete mixing, concreting can be carried out. It is recommended to mix for at least 1 minute per cubic meter of concrete.
- Liquid concrete waterproofing can be added to the batching or truck mixer during concrete production.
Be careful not to pour the liquid concrete waterproofing additive directly onto dry cement.

Mechanism of action of liquid concrete waterproofing product
One of the materials that create liquid concrete waterproofing is a lignosulfonate-based lubricant that, when added to the mixture, the polar head of the lubricant molecule attaches to the cement particles and, due to the polarization of the particles, prevents them from clumping and causes the mixture to be fluid with good particle dispersion. As a result, this fluidity spreads the particles well and increases the density of the concrete and, as a result, reduces permeability. On the other hand, the presence of concrete sealing resins in the liquid concrete waterproofing formulation increases the adhesion of the mixed components and reduces permeability.
Proper safety conditions when using liquid concrete waterproofing
