BISEAL WA
BISEAL WA is a chloride-free waterproofing liquid admixture, monocomponent, specifically designed to reduce permeability and capillary water absorption in mortars and concrete, providing effective protection against moisture and improving long-term durability.
Due to its plasticizing effect and easy integration into the mixing water, BISEAL WA enhances workability of fresh concrete while reducing water-cement ratio. Ideal for both structural and decorative applications, it helps prevent efflorescence and surface salt formation, and increases resistance to freeze-thaw cycles. This product is suitable for waterproofing mortars and concrete exposed to direct water pressure or humid environments, such as underground or marine areas.
Applications
- Waterproof concrete and mortars in foundations, basements, tunnels, channels and marine structures.
- Interior or exterior renders on concrete blocks, bricks and cement-based surfaces.
- Waterproof coatings for swimming pools, reservoirs, wells and elevator shafts.
Advantages
- Easy to use, added directly into mixing water.
- Improves durability against weathering and freeze-thaw cycles.
- Reduces efflorescence and superficial salt formation.
- Enhances workability and allows reduced water ratio in fresh concrete.
Instructions for use
Add BISEAL WA directly into the mixing water before incorporating into mortar or concrete. For renders, apply two 1–1.5 cm coats, finishing with sponge or trowel.
Consumption
Estimated dosage: 1–3% of cement weight (0.5–1.5 kg per 50 kg cement bag). Preliminary testing is recommended to optimize dosage.
Packaging
Available in 20 kg jerrycans, 220 kg drums and 1000 kg containers.
Safety and precautions
Use rubber gloves, protective goggles and clothing. Avoid contact with skin and eyes. In case of exposure, rinse with water and seek medical advice if needed.
