Waterproof Powder Concrete Admix
Description
Description : Waterproof Powder Concrete Admix
Waterproof powder is a material based on fatty acids that contains pore fillers and water repellants which, during the reaction with the compounds obtained from cement hydration, flows inside the pores and cavities and assumes the role of water and moisture repellency.
Features and benefits:
- Construction of impermeable and waterproof concrete
- Prevention of sulfate attack and alkalization
- No negative impact on the compressive strength of concrete
Application:
- Production and construction of durable and high-quality concrete
- Suitable for the production of precast concrete parts

Product Description – Concrete Powder Waterproofing
The reason for the presence of compacted sections is the reduction of fillers and fines in concrete, which causes the creation of voids between the aggregates, and the concrete will suffer from poor permeability and quality loss. Permeable concrete is weak against the penetration of water and destructive ions, and as a result, it will have lower stability and will be more porous. To fill the voids between the aggregates, using a concrete waterproof powder additive is a suitable option. Concrete waterproof powder is a material based on fatty acids that includes pore-filling materials and water-repellent materials that, during the reaction with the compounds resulting from cement hydration, flow into the pores and cavities and assume the role of repelling water and moisture. The impermeability of concrete is one of the determining factors for predicting and evaluating the strength and durability of concrete. If concrete is produced with the correct mix design and with a good water-to-cement ratio and aggregates, its permeability will be reduced. Adding a controlled amount of powdered concrete waterproofing materials to the mix will produce a better quality and denser concrete with a significant reduction in permeability. The use of this product also prevents sulfate attack and alkalization.
Using this product increases the durability of concrete and prevents damage from chemical reactions. Powder waterproofing can also be used to produce impermeable concrete. Another feature of this product is preventing moisture and permeability of concrete.
This product for concrete refers to products that are used to increase the resistance of concrete to water penetration and maintain its strength against moisture. This product works as a waterproofing agent for concrete. This additive helps concrete to have a structure that can more effectively resist water, moisture, and even temperature changes.
Concrete powder waterproof packaging

20 kg bag
Standard consumption of waterproof powder
The amount of powdered waterproofing used depends on the thickness of the concrete. In principle, for concrete up to 15 centimeters thick, about 3 percent of the weight of the cement used can be used, and for concrete thicknesses over 15 centimeters, 1.5 to 2 percent of the weight of the cement used can be used.
Note: Using more than 3 times the above without using superplasticizer will reduce the strength of the concrete.
Principles of maintaining powder waterproofing
Duration: One year in original packaging.
Conditions: Away from cold and frost, heat and direct and prolonged sunlight.
Best storage temperature: +10 to +30 degrees
How to properly use concrete powder waterproofing
What is the correct way to use concrete powder waterproofing?
- The calculated amount of powdered waterproof additive should be diluted with 2 times the volume of concrete mixing water, depending on the grade of concrete. The diluted additive should be added slowly to the concrete while it is being mixed.
- This product can be added to the ready-mixed concrete and after complete mixing, concreting can be carried out.
- Concrete waterproofing powder can be added to the batching or truck mixer during concrete production.
Tips:
- The equivalent weight of the concrete waterproofing powder used should be reduced from the amount of water in the concrete mixture.
- It is mandatory to use powdered concrete waterproofing with water reducing agents (concrete lubricants). The best way to add powdered waterproofing admixture is to add it after the lubricants have been mixed with the concrete mix.
- It is recommended that mixing operation be carried out for at least 1 minute per cubic meter of concrete.
Properties and effects of concrete powder waterproofing
- Transferring the hydrophobic properties of powdered waterproofing material as a filler to concrete
- Making concrete impermeable and waterproofing it
- Blocking all pores and porosity caused by the fraction of fine grains
- Preventing sulfate attack and alkalization
- Preventing the penetration of destructive factors into the concrete
- The structure remains watertight in the long term, due to the sealing of concrete capillaries.
- No negative impact on the compressive strength of concrete
- Preventing ions and corrosive chemical agents from entering the concrete core
- Ease of dispersion of particles in the concrete mix
- Preventing the penetration of chemical solutions
Applications of concrete powder waterproofing
- Production of concrete resistant to penetration of chemical solutions
- Suitable for sealing concrete and in fact sealing concrete structures.
- Production and construction of durable and high-quality concrete
- Suitable for building foundations for marine piers
- Production and construction of concrete in salt marshes and areas under attack by destructive ions and sulfates
- For sealing tanks, dams and tunnels
- Efficiency for the production and implementation of concrete projects near the sea
- Suitable for producing hydrophobic concrete prefabricated parts

Mechanism of action of powder waterproofing on concrete quality
The powdered waterproof concrete admixture is a micronized hydrophobic and waterproof filler and, due to its specific physical structure, it is easily dispersed into the concrete mixture and fills all the pores and gaps between the aggregates, thus eliminating the filler and fine particles in the concrete mixture. In addition, it also blocks the capillary tubes that form as a result of water evaporation in the concrete, and ultimately the concrete becomes impermeable and safe against the penetration of water, destructive ions, and corrosive chemicals into the concrete.
Safety tips for using concrete powder waterproofing
- In case of accidental contact with skin or eyes, rinse with fresh water.
- Wear appropriate goggles, mask, and gloves when using.
- This substance causes sensitivity upon contact with the skin.
- This material is not hazardous or toxic to the environment.
