SikaGrout-212 HP is a high-performance, cementitious, non-shrink grout that expands in two stages (plastic and hardened) to counteract shrinkage. It offers high early and 28-day strengths, flowable consistency, and is designed not to segregate or bleed. Suitable for applications from 10mm to 100mm. Available from ProTrade Warehouse across Australia.
Uses
SikaGrout 212HP is used for flowable grouting applications such as machine baseplates, anchor bolts, bridge bearing pads and shear key grouting, pre-cast concrete sections, cavities, gaps, and recesses requiring high performance.

Application Instructions
Equipment
SikaGrout®-212 HP must be mechanically mixed using a mechanical grout mixer or a suitable drum mixer. The grout mixer will reduce the chances of the mix becoming lumpy or aerated. Smaller quantities should be mixed in clean drum using an electric drill and spiral drill and spiral mixer at a speed of approximately 500 rpm. DO NOT MIX BY HAND.
Substrate Quality
Surface Prep:
Correct and thorough surface preparation is essential to achieve the high performance qualities of SikaGrout®-212 HP.
All surfaces must be clean, sound and free from dust, ice, oils, grease or other surface contaminants such as curing membranes and form release agent etc. Bolt holes and fixing pockets should be free of dirt and debris by air blasting. For maximum bond, surfaces should be abraded or roughened, preferably by mechanical means such as needle gun, grit blasting, grinding etc.
All prepared surfaces must be saturated with water several hours prior to grouting, ensuring it is free of any surface water or puddles.
Formwork:
The formwork used must be leak proof to allow for free flowing SikaGrout®-212 HP. The formwork should be arranged so that the grout head is maintained on the side above the level of the underside of the base plate. This will allow gravity flow to completely fill the void to be grouted.
Formwork should be coated with form oil to allow easy removal of forms. Ensure adequate air holes are provided.
Temperature Control:
Temperature affects setting time and rate of increase for strength. For optimum performance maintain grout, concrete and/or steel substrates within the range of 18-25 °C prior to, during, and for 48 hours after placement of the grout.
Mixing
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®-212 HP into it while continuously mixing. Add the remaining water until the desired consistency is obtained. Mix for 3–5 minutes with a low speed drill (500 rpm max.). Allow to stand so any entrapped air can escape. Do not add more water to increase flow of the grout if a mix has stiffened due to time delays. If the grout is unworkable discard.
Application
SikaGrout-212 HP can be placed by gravity flow or by pump. It is essential that proper placing on the job site is practised to ensure placement is completed without problems. Sufficient labour, grout and equipment must be present to ensure continuous placement.
Gravity Flow
Mixed grout should be poured one side of the void to avoid air entrapment. Grout is best poured over short distances to ensure this. Use a suitable header box, maintaining the grout head at all times to ensure continuous flow. To facilitate grout compaction and top plate contact, use rodding, tamping or flexible strapping in short strokes while maintaining an adequate head of grout. Do not vibrate as this will cause segregation. Any adjacent machinery or equipment causing vibration should be shut down until initial set (5 to 6hours).
Pumping
When pumping SikaGrout-212 HP, ensure the pump is suitable for the grout consistency and for the distance and height it is to be pumped. A positive displacement pump is recommended. Place grout by pumping into the farthest corner, filling the space gradually. Ensure that air is not entrapped under the base plate.

Colour Accuracy Disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
