• HKHA/MTS (2014/2016) Specification Part D Clause 2.1.20

Place 70–80 % of the premeasured clean water (depending on consistency required - refer to ‘Mix Ratio’) into a clean container and gradually add the whole bag of SikaGrout®-214 HK into it while continuously mixing. Add the remaining water until the desired consistency is obtained. Mix for 2–3 minutes with a low speed drill (maximum 500 rpm) until the mixture become homogeneous. Hold the fresh mortar in the container for 1–2 minutes, and then mix again for 1–2 minutes.

After mixing, stir lightly with a spatula for a few seconds to release any entrapped air. The grout is then poured immediately into the prepared formwork.

When carrying out base plate grouting, ensure sufficient pressure head is maintained for uninterrupted mortar flow. For formwork repair, the prepared formwork must be firmly in place and kept watertight.

When placing grout over a large area, it is important to maintain a continuous flow throughout. Work sequence must be properly organized to ensure an uninterrupted flow.

For sections thicker than 100 mm or for large grouting areas, it is necessary to mix SikaGrout®-214 HK with graded 10 mm silt free aggregates to minimize temperature rise generated during curing stage. The quantity of aggregates should not exceed 1 part aggregates to 1 part SikaGrout®-214 HK by weight. Other precautions such as the use of chilled water, insulation of the formwork or baseplate may be required. Please consult Technical Service Department for assistance.

To further ensure that air entrapped during mixing is allowed to fully escape, it may be necessary to make breather holes. Use steel rods or chains to assist the flow of grout where necessary.

Clean all tools and equipment with water immediately after use. Hardened mortar can only be mechanically removed.
