Hydro Build LW Chemical

Listing ID #4270553

Dubond’s Hydrobuild LW is specially formulated integral liquid waterproofing compound composed of surface active plasticising agents, polymers & additives. It is used as an additive for cement concrete, mortar & plasters. It makes concrete cohesive and prevents segregation. Hydrobuild LW is an integral waterproofing admixture for concrete and mortar which chemically converts the water soluble compounds present into concrete/mortar into stable water insoluble compounds. It is used in all types of concrete/mortar requiring water impermeability. It is based on high performance polymers. Conforms to IS 2645 : 2003 and IS 9103 – 2000 standards.
Green Building Rating

• Low Emission
• Low Ecological Impact
• Health Care
• Water Based

Areas of Application

• Waterproofing of concrete and sand-cement mortars used in :
• Basements
• Roof slabs and Screeds
• Water tanks & water retaining structures
• External Plastering
• Bathrooms and Balconies
• Sunk and Drains

Features & Benefits

• Increases Workability
• Easier Placing
• Better Compaction and Finishing by acting as Viscosity Modifier
• Lowers cement content for increase in specified Strength, Workability & Durability
• Higher Cohesion
• Breaks the Salinity of Water by converting them into Salt Crystals
• Lower water requirement for given Workability
• Chloride free
• Increases Extra Bonding Strength
• Reduce risk of Segregation and Bleeding
• Reduce risk of Shrinkage Cracks due to Heat of Hydration
• Reduce risk of Honey Combing
• Corrosion resistant - reduces the risk of rusting of reinforcement by breaking the chain of Rust Electrons -
• Makes concrete more cohesive, hence protects steel better against corrosion

Method of Application

• Charge cement & aggregates to concrete mixer as per the mix design, mix in dry state for 12 minutes.
• Start addition of 75–80% mixing water & mix for 2-3 minutes.
• Hydrobuild LW is added as per the recommended dosage into the remaining mixing / gauging water,
• Then add to concrete mixer & mix for another 2 minutes.
• Place the concrete or apply plaster, as needed .
• Cure the applied mortar or concrete as per good construction practices.

Precautions & Limitations
Do not add Hydrobuild LW directly to dry cement & aggregate mix. Maintain water-cement ratio as low as possible. Do not increase the dosage of Hydrobuild LW than the recommendation.
Health & Safety Precautions
Use rubber hand gloves & safety goggles, while using Hydrobuild LW. In case of contact with skin, wash with plenty of water. Keep out of reach of children.
