Deep Protection. Permanent Waterproofing. Stronger Concrete.

PENETRON is a surface-applied, integral crystalline waterproofing material designed to waterproof and protect concrete in-depth.
It consists of Portland cement, specially treated quartz sand and active chemicals. When PENETRON is applied to a properly prepared concrete surface, its active chemicals react with moisture and the by-products of cement hydration to generate an insoluble crystalline structure within the concrete.
These crystals penetrate and fill concrete’s capillary tracts, pores and minor shrinkage cracks, helping prevent further water ingress—even under hydrostatic pressure—while still allowing vapor to pass through the structure so the concrete can “breathe.”
PENETRON remains dormant within the concrete after curing and can reactivate when moisture is present, helping seal capillary tracts and hairline cracks.
Unlike a conventional surface membrane, PENETRON works within the concrete. Its active crystalline technology penetrates the concrete’s capillary network and creates insoluble crystals that block pathways through which water can travel. PENETRON can be applied from either the positive or negative side of structurally sound concrete and remains effective even if the treated surface is subsequently damaged.
Available through Baral Chemical Company Ltd., a professional Chemical Company serving Bangladesh’s construction sector, PENETRON offers advanced crystalline technology for demanding waterproofing and concrete-protection applications.

PENETRON is suitable for a wide range of concrete waterproofing and protection applications, including below-ground structures, water-retaining structures and major infrastructure projects.
Before applying PENETRON, the concrete surface must be properly prepared and have an open capillary surface.
Correct surface preparation is essential for penetration of PENETRON’s active chemicals into the concrete.
Mix PENETRON mechanically with clean water until a creamy, thick-oil-like consistency is achieved. Prepare only the quantity that can be used within approximately 20 minutes and stir frequently during use. If the mixture starts to set, do not add additional water. Re-stir the material to restore workability.
PENETRON can be applied in slurry consistency using a masonry brush or suitable power-spray equipment. Depending on the specification, apply one or two coats. When two coats are required, the second coat should be applied while the first coat is still “green.”
For horizontal fresh concrete applications, PENETRON may also be applied in dry-powder consistency and troweled into the concrete after initial set.
Application requirements may vary depending on the project specification and substrate condition.
| Application Area | Application Method | Approx. Rate |
|---|---|---|
| Vertical Surfaces | Two Coats | 0.7–0.8 kg/m² |
| Horizontal Hardened Concrete | One Slurry Coat | 1.1 kg/m² |
| Fresh Horizontal Concrete | Dry Sprinkle | 1.0 kg/m² |
| Construction Joints | Specified Application | 1.6 kg/m² |
| Blinding Concrete | Specified Application | 1.4 kg/m² |
After application, treated areas should be kept damp for five days.
PENETRON is available in 22.7 kg (50 lb) bags.
PENETRON is also available in 25 kg (55 lb) pails.
Store PENETRON products under dry conditions at a minimum temperature of approximately 7°C (45°F).
PENETRON contains cement and is alkaline. Appropriate eye, skin and respiratory protection should be used during handling and application.

Practical feedback about PENETRON waterproofing applications, project planning and technical support.
We considered PENETRON for basement waterproofing where long-term concrete protection was important. The technical guidance helped our team understand surface preparation and curing requirements.
PENETRON was selected for a water-retaining concrete application. Proper substrate preparation and following the recommended application procedure were important parts of the work.
The technical information was useful when planning application on concrete surfaces. Guidance on mixing ratio, application rate and curing made project planning easier.
We needed a waterproofing system for below-ground concrete work. The PENETRON application method suited the project requirements, with particular attention given to surface preparation.
The product information clearly explained the mixing and application procedure. Technical guidance was useful when determining the appropriate application approach for the concrete structure.
For waterproofing work, correct application is as important as product selection. Technical support helped our team understand the recommended preparation, application and post-treatment procedures.
