DBM® W Liquid Permeability Reducing Admixture

DBM® W by GCP Applied Technologies is a specialized liquid permeability-reducing admixture designed to enhance the durability and longevity of concrete and mortar structures. By creating a hydrophobic barrier within the capillary pores, DBM® W effectively reduces the ingress of water, chlorides, and other aggressive agents, thereby protecting embedded reinforcement from corrosion and extending the service life of the structure.

Key Features

• Significantly reduces water and chloride permeability in fresh and hardened concrete.
• Compatible with a wide range of cement types and mineral admixtures.
• Improves resistance to freeze-thaw cycles and chemical attack.
• Easy to use: simply add to the mixing water or directly into the mixer.

Applications

DBM® W is ideal for critical infrastructure projects including marine structures, bridge decks, parking garages, and industrial floors where exposure to de-icing salts, seawater, or sulfates is a concern. It is suitable for use in ready-mix concrete, site-mixed concrete, and various types of mortar applications.
