Formulated for use in concrete with a medium to high workability (>S3 Consistence) with a minimum cement content of 350 kg/m³ and a maximum water/cement ratio of 0.45
Sika® Watertight Concrete Powder has been specifically formulated to produce a S3 consistence with a w/c ratio of <0.45 at 350 kg/m³ without the addition of a separate HRWR/Superplasticiser
Subject to material package and cement content water reductions of between typically 10–15% can be achieved. Laboratory trials are always recommended to evaluate and confirm actual water reduction
Should the addition of a HRWR/Superplasticiser be required to achieve a w/c ratio of <0.45 it is recommended that a Sika® ViscoCrete HRWR/Superplasticiser be selected
