25kg 215 Sika Grout
Pumpable shrinkage compensated cementitious grout
SikaGrout®-215 is a pumpable dual-shrinkage compensated, self-levelling, prebagged cementitious grout with extended working time to suit local ambient temperatures.
– Easy to mix and apply
– Good flow characteristics
– Rapid strength development
SikaGrout®-215 is suitable for repairs to the following concrete structures:
Columns in precast construction
Honeycombs (pre-packed grouting)
SikaGrout®-215 is suitable for grouting works with clearances as low as 5 mm.
Easy to mix and apply
Good flow characteristics
Rapid strength development
High ultimate strengths
Dense and non-shrink (2-step expansion – Gaseous expansion in plastic stage & Crystalline expansion in hardened stage)
Extended working time
Good pumping properties
Tested for compatibility with drinking water, PSB report 57S030976-SLE-2
Place about 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®-215 into it while continuously mixing. Add the remaining water and continue mixing until the desired consistency is obtained. Mix for 2 to 3 minutes with a slow speed drill and paddle (~500 rpm).
For large quantities mixing, the use of a forced-action mixer of rotating pan, paddle or trough type is preferred. Free fall mixers should not be used.
Use SikaGrout®-215 for grouting only.
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 baseplate 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 organised to ensure an uninterrupted flow. In large areas, SikaGrout®-215 may be pumped using heavy duty diaphragm pumps. Screw feed and piston pumps may also be used.
Specific Areas of Application
Grouting under baseplate – pourable consistency
Formwork grouting (example deep honeycombs, column reinforcements, etc.
pouring method – flowable / pourable consistency
prepacked method – flowable consistency.
Grouting anchor bolts – stiff consistency
Grouting large volumes – for sections thicker than 50 mm, it is necessary to fill SikaGrout®-215 with graded 10 mm silt free aggregates to minimise temperature rise generated during the curing stage.
