Integral Water Proofing-LWP
DESCRIPTION:
Dr. Wall Care LWP is a liquid Integral waterproofing compound for concrete and mortar, forms an internal barrier against water penetration, also increases the workability of mortar, reduces water absorption, and thereby protect against freeze-thaw effect. It is a specially formulated integral liquid waterproofing compound composed of surface-active plasticizer agents, polymers & additives. It is used as an additive for cement concrete, mortar & plasters. It makes concrete cohesive and prevents segregation.
AREAS OF APPLICATION:
- Sunken slab,
- podium slab.
- Water retaining structures.
- Swimming pools.
- Roof slabs and cement screeds / mortar
- Basements
- External plastering
FEATURES:
• Improves the workability and cohesiveness of concrete & cement mortar
• Good water reduction helps to improve durability
• Provides good surface finish
• Reduced segregation and helps to protect steel corrosion
• Minimizes shrinkage crack in cement plaster and concrete
• Minimizes the permeability and increases the waterproofing properties of concrete and cement mortar

MIXING INSTRUCTIONS:
- The dosage of Dr. Wall Care LWP is 200ml per 50kgs of cement.
- Mixing It is generally recommended to reduce 15 - 20% of the mixing water in comparison to the normal mixes (without LWP) to ensure no loss in strength.
- Place cement and aggregates into the concrete mixer as per the mix design. Mix for one minute and add about 80% pre-measured water and further mix for 2-3 minutes. Shake LWP well and add as per the recommended dosage into the remaining 20% water. Add this mixture into the concrete mixer and mix for another 2 minutes. Place the obtained concrete as needed.
Precautions & Limitations
- Do not add Dr. Wall Care LWP directly to dry cement & aggregate mix.
- Maintain water-cement ratio as low as possible.
- Do not increase the dosage of Dr. Wall Care LWP than the recommendation.
