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®-220 into it while continuously mixing. Add the remaining water until the desired consistency is obtained.

Mix for 2–3 minutes with a mixer blade attached to a slow speed drill (500 rpm max.)

Do not use a free-fall mixer.

The formwork shall be constructed to be leak proof. This can be achieved by using foam rubber strips or mastic sealant beneath the constructed formwork and between joints.

After mixing, stir lightly with a spatula for a few seconds to release any entrapped air. Pour the mortar within 10–15 minutes after mixing.
When carrying out baseplate grouting, ensure sufficient pressure head is maintained to keep mortar flowing. Exposed parts of the mortar surface should be kept as small as possible.

Any bolt pockets must be grouted prior to grouting between the substrate and the base plate. Pouring should be from one side of the void to eliminate any air or pre-soaking water becoming trapped under the baseplate. It is advisable to pour the grout across the shortest distance of travel. The grout head must be maintained at all times so that a continuous grout front is achieved.

Grouting large volumes

For sections thicker than 50 mm, it is necessary to fill the SikaGrout®-220 with graded 10 mm silt free aggregate to minimise temperature rise. The quantity of aggregate should not exceed 1 part aggregate to 1 part SikaGrout®-220 by weight. Mixing ratio will be determined by consistency required and moisture content of aggregates used. A preliminary trial is recommended.

On completion of the grouting operation, exposed areas should be thoroughly cured. This should be done by the use of Antisol®-E curing compound, continuous application of water and/or wet Hessian.

Clean all tools and application equipment with water immediately after use. Hardened or cured material can only be mechanically removed.
