SikaGrout®-212 HP

Dual Shrinkage Compensated high strength cementitious grout for applications from 10 mm to 100 mm.

SikaGrout-212 HP is a cementitious, non-shrink, high performance grout that expands in two stages in both the plastic and hardened states (class A and C) to counteract the shrinkage normally associated with cement grouts.

Characteristics and advantages include:
  • Shrinkage compensating properties, classed as a non-shrink grout as per CRD-C 621-81.
  • High early strengths.
  • High 28 day strengths.
  • Flowable consistency.
  • Adjustable consistency.
  • Formulated to not segregate or bleed.
  • Excellent impact and thermal resistance.
  • Non corrosive to steel or iron.
  • Lab tested in accordance with AS 1478.2

Application

Application steps

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.

MIXING

  • Plastic grout, add 2.8 litres of water per 20 kg bag. 
  • Flowable grout, add 3.7 litres of water per 20 kg bag.
  • Add the powder component to approximately 70 % of the total amount water component while mixing.
  • Add the remaining 30 % of the water component to the grout at a steady rate while continuing to mix.

  • Mix until the grout appears homogenous (3–5 minutes).

    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 6 hours).

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.
