PC-Conblend® WP

Integral Waterproofing Liquid Admixture for Durable & Impermeable Concrete

PACKAGING

PC-Conblend® WP Available in 20 kg, 50 kg, and 200 kg drums

PC-Conblend® WP is a high-performance integral waterproofing liquid admixture designed for use in concrete and mortar. It is added directly during the batching or mixing process to significantly reduce water penetration caused by capillary action and hydrostatic pressure in hardened concrete. By forming a dense and impermeable concrete matrix, PC-Conblend® WP enhances long-term durability and protects structures against moisture ingress. In addition to waterproofing performance, it improves workability and cohesion of fresh concrete and mortar without increasing water content, ensuring consistent quality and ease of placement on site.

ADVANTAGES

Liquid admixture for integral waterproofing
Reduces permeability of concrete and mortar
Improves workability and cohesion of fresh mix
Enhances durability of hardened concrete
Minimizes shrinkage-related cracks
Reduces efflorescence and surface defects
Compatible with most common concrete admixtures
Cost-effective due to low dosage requirement

USES

Recommended for use in structural and non-structural concrete where waterproofing and reduced permeability are required. It is suitable for roof slabs, screeds, basements, water-retaining structures, foundations, external plastering, canals, culverts, tunnels, and sewerage works where long-term protection against moisture is essential.

APPLICATION

PC-Conblend® WP is supplied as a ready-to-use liquid admixture. For best results, the measured quantity should be diluted with the mixing water to ensure uniform dispersion before adding to the concrete or mortar mix. It should be introduced during the batching or mixing stage. Maintain the water–cement ratio as low as possible to achieve the desired workability and waterproofing performance. Concrete or mortar should be placed, compacted, and cured properly in accordance with good construction practices to achieve maximum durability and impermeability.

DOSAGE

The optimum dosage of PC-Conblend® WP should be determined through site trials using the actual materials, mix design, and site conditions. As a general guideline, the recommended dosage ranges from 0.1% to 0.4% by weight of cementitious material, depending on cement content, exposure conditions, and required waterproofing performance. Variations in aggregates, cement type, or environmental conditions may require dosage adjustments. For applications outside the recommended range, consultation with the technical team is advised.

STORAGE & SHELF LIFE

The product should be stored in its original, unopened containers in a cool, dry, and covered area, protected from direct sunlight and extreme temperatures. Storage temperatures should not fall below +5°C. If the product becomes frozen, it should be thawed naturally at temperatures above +5°C and gently mixed before use. When stored under recommended conditions, the shelf life is 12 months from the date of manufacture.

SAFETY PRECAUTIONS

PC-Conblend® WP is chloride-free and does not initiate or promote corrosion of steel reinforcement or embedded metal components. By minimizing water penetration and reducing the movement of aggressive ions within the concrete, it lowers the risk of reinforcement corrosion. This protective action helps maintain the structural integrity of reinforced concrete and enhances overall durability in both normal and aggressive exposure conditions.

Non-hazardous and water-based; however, standard safety precautions should be followed. Avoid ingestion and prolonged contact with skin or eyes. Protective gloves and safety goggles are recommended during handling. In case of skin contact, wash immediately with clean water. If the product comes into contact with the eyes, rinse thoroughly with plenty of water and seek medical advice. If swallowed, seek medical attention immediately and do not induce vomiting. Keep out of reach of children.
