Integral waterproofing liquid admixture forconcrete and mortar


To minimise permeability and increase the waterproofingproperties of concrete and cement sand mortars for criticalapplications like roof slabs and screeds, basements, externalplastering, bathroom floors, water tanks, sumps, drains etc.


  • Liquid admixture: Instant and complete dispersionthroughout the mix. Uniform waterproofing throughoutconcrete matrix.
  • High efficiency: Dramatic reduction in permeability ofconcrete/ mortar.
  • Improved workability: Improves compaction of concreteand mortar, even where harsh sands or aggregates are used.
  • Improved concrete quality : Minimises porosity and honeycombing. Produces dense homogenous concrete.

Conplast X421IC is a dark brown liquid based onlignosulphonates which mixes readily with water andtherefore disperses evenly.Conplast X421IC waterproofs by improving the quality of theconcrete or mortar. It reduces the water demand for requiredworkability and minimises segregation and bleeding. Thusit is more efficient compared to traditional powderwaterproofers as its use results in two fold improvement ofconcrete or mortar.

Chloride content: Nil as per IS:2645-2003
Compatibility: Can be used with all types ofcements,including pozzolanic but not High Alumina Cement.
Permeability to water: Less than 15% as compared to 50%max. allowable under IS:2645 compared to control sample.
Setting Time: No significant effect on setting time of concreteor mortar.
Compressive strength: Maintains compressive strengthequal to control concrete or mortar and can even improve onstrength property if full advantage of water reduction potentialis utilised.
Workability: Improves workability at reduced water cementratio
