Description

Specifically formulated to produce high quality watertight concrete. Used as a constituent of the Sika® Watertight concrete system and contact with Sika Ltd is essential to ensure that full system compliance is achieved.

Features and benefits:

Reduced water absorption.
Reduced water penetration.
Accurate control of w/c ratio.
In combination with a Sika® ViscoCrete HRWR/Superplasticiser, SCC can be produced.
Reduced shrinkage and creep.
Provided in a water soluble bag for ease of dispensing.
Consistent performance.
Reduced stock and environmental issues at production plant.

Features:

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.
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.
DoP 02 07 05 04 001 0 000012 1088, certified by Factory Production Control Body 0086, Certificate 541325, and provided with the CE mark.
