Water Repellent Admixture for Concrete



MNC-D1 is a stable dispersion of stearate and other water repellent compounds that is added into ready mixed concrete during mixing. MNC-D1 is a ready-to-use, factory prepared powder that will simplify handling and eliminate guesswork. It meets the requirements of the following chemical admixture specifications for concrete: JC474-1999.


Architects, engineers, contractors, and other authorities agree that even good quality concretes, mortars, etc. that are properly placed, set or applied then cured, are inherently porous or permeable to water. The free passage of moisture occurs in pores formed during and after placing. MNC-D1 forms an internal barrier against water transmission in mixes used for ready mixed or precast concrete.


The addition of MNC-D1 will reduce the amount of water that permeates through the concrete. Reducing the passage of water will provide beneficial advantages by:

Increasing resistance to weathering

wetting and drying

freezing and thawing.

Increase resistance to chemical attack

Reduce the potential for efflorescence

Reduce the probability of corrosion of embedded metal

Improved Product Quality

Higher quality concrete will result from the use of MNC-D1. The workability of mixes will be improved especially in low cement content concrete mixes. The protection of embedded steel and resistance to bacteria or fungus growth may also be increased by keeping the concrete drier.


Reduces water penetration in mortar and concrete under hydraulic pressure. Increases concrete compactness, anti-crack and anti-seepage. The anti-seepage can reach P25, having the effect of shrinkage compensation and saving cement.

It can be applied in residential and industrial projects such as floor surface, basement, tunnel, water supply and sewerage system, pumping station etc., where water-repellent in the concrete is necessary

The concrete with this product does not reduce the strength, has no pollution to water, and no corrosion to steel.

It can be used for the interior water-repellent, instead of exterior surface treatment so that it provides continuous protection.

It extends the Expansion Joint Spacing, continuous pouring and grouting for 60 m without Expansion Joints. Thus, it reduces the working time.

Its cost is only one third of 2 layers of felt 3 coats of bitumastic.

Combined with water-reducing and air-entraining admixtures, better water-repellent effect can be achieved. The air-entraining agent provides stable microscopic air void system with proper bubble size and spacing, which can reduce the room and path for permeability. Water reducing agent can reduce water, improve workability, and increase concrete compactness and dens
