Product BrochureProduct Details:

Uses To minimise permeability and increase the waterproofing properties of concrete and cement sand mortars for critical applications like roof slabs and screeds, basements, external plastering, bathroom floors, water tanks, sumps, drains etc. Advantages „ Liquid admixture: Instant and complete dispersion throughout the mix. Uniform waterproofing throughout concrete matrix. „ High efficiency: Dramatic reduction in permeability of concrete/ mortar „ Improved workability: Improves compaction of concrete and mortar, even where harsh sands or aggregates are used. „ Improved concrete quality : Minimises porosity and honey combing. Produces dense homogenous concrete. Standards compliance Conplast WL conforms to IS:2645-2003. Description Conplast WL is a dark brown liquid based on lignosulphonates which mixes readily with water and therefore disperses evenly. Conplast WL waterproofs by improving the quality of the concrete or mortar. It reduces the water demand for required workability and minimises segregation and bleeding. Thus it is more efficient compared to traditional powder waterproofers as its use results in two fold improvement of concrete or mortar. Technical support Fosroc provides a technical advisory service for onsite assistance and advice on admixture selection, evaluation trials and dispensing equipment. Technical data and guidance can be provided for admixtures and other products for use with fresh and hardened concrete. Properties Chloride content : As per IS:2645-2003 Compatibility : Can be used with all types of cements,including pozzolanic but not High Alumina Cement. Permeability to water : Less than 15% as compared to 50% max. allowable under IS:2645compared to control sample. Setting Time: No significant effect on setting time of concrete or mortar. Compressive Strength : Maintains compressive strength equal to control concrete or mortar and can even improve on strength property if full advantage of water reduction potential is utilised. Workability: Improves workability at reduced water cement ratio Application instructions Mortar: Conplast WL is ideal for use with all sand/cement mortars where it is required to reduce permeability to a minimum. Concrete: Conplast WL is recommended for all general mass concrete work where, due to harsh aggregates, difficulty of compaction or mix control, the risk of porosity and permeability must be minimised. Eg. Basements, bund walls, tanks, balcony, floor and roof slabs. N.B.: The minimum dosage is 125ml and the maximum is 200ml per 50kgs of cement. If maximum dosage is used a minimum of 15% water should be reduced to ensure no loss in strength. Site trials shall be carried out to arrive at the optimum dosage. The required quantity of Conplast WL is measured and stir into the first or second bucket of water. Conplast WL water mixture shall be added to the concrete or mortar and mixed thoroughly. Mixing shall be continued and further water shall be added until the required workability is obtained.
