Yashika Iwl

IWL is a dark brown liquid based on ligno sulphonates which mixes readily with water and therefore, disperses evenly. IWL waterproofs by improving the quality of the concrete or mortar. It reduces the water demand for required workability and, minimises segregation and bleeding. The surfactants in IWL react in the cement, sand mixture to produce insoluble hydrophobic precipitates. These have a two-fold effect in reducing the permeability of the mix as they both repel moisture, due to their hydrophobic nature, and act as pore blocking agents to reduce the inter connectivity of porosity in the mix.

Uses

1. To minimize permeability and increase the waterproofing properties of concrete and cement sand mortars for critical applications like roof slabs and screeds, basements, internal and \external plastering, bathroom floors, water tanks, sumps, drains etc.

Advantages

1. Provides integral protection to the mortar, render or screed, ensuring reduced permeability all through the applied material and not only on the surface.
2. Reduced water permeability minimizes efflorescence caused by transport of dissolved salts through the mix.
3. Entrained air bubbles assist in the formation of a stable cohesive mix, reducing segregation and bleeding
and improving spreading and placing.
4. Air entrainment improves mortar workability, allowing lower water contents to be used.

Consumption

The minimum dosage is 125ml and the maximum is 200ml per 50kgs of cement. Site trials shall be carried out to arrive at the optimum dosage

Packaging

YASHIKA IWL is supplied in 500ml, 1, 5, 20 and 200 litre containers.
