SikaGrout®-228

High strength shrinkage compensated cementitious grout

SikaGrout®-228 is a high strength, pumpable, non-shrink, self-levelling, prebagged cementitious grouting mortar with extended working time to suit local ambient temperatures.

SikaGrout®-228 is an economical and easy to use material requiring only the addition of water. Other beneficial properties are:
  • Easy to mix and apply
  • Pumpable with good flow characteristics
  • Very high early and ultimate strength
  • Impact resistant
  • Non-corrosive
  • Non-toxic
  • Iron and chloride free
  • Dense and non-shrink (2-step expansion)
  • Extended working time

Application steps

MIXING

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®-228 into it while continuously mixing. Add the remaining water until the desired consistency is obtained. Mix for 2–3 minutes with a mixing paddle attached to a slow speed drill (500 rpm max.). Do not use a free-fall mixer.

APPLICATION

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 the 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 shall be from one side of the void to eliminate any air or pre-soaking water getting 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®-228 with graded 10 mm silt free aggregate to minimise temperature rise. The quantity of aggregate shall not exceed 1 part aggregate to 1 part SikaGrout®-228 by weight. Mixing ratio will be determined by consistency required and moisture content of aggregates used. A preliminary trial is recommended.

CURING TREATMENT

On completion of the grouting operation, exposed areas shall be cured with Antisol®-E curing compound or continuous application of water and/or wet Hessian.

CLEANING OF TOOLS

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