Usage

SikaGrout®-214-11 HS is designed to counteract the normal shrinkage of mortar and concrete and to absorb and minimize effects of vibration on foundations. The high early strength property is suitable for work that requires early loads including machine bases structural columns, prestressed girders, bridge bearings, rail posts and seatings bolts etc.

Application steps

MIXING

Powder should be added to the pre-gauged water to suit the desired consistency.
Mix mechanically for at least 3 minutes with a low speed electric drill (max. 500 r.p.m.) with a disc agitator attached, until a smooth consistency is achieved.
Mixing equipment such as two arms, forced action basket/pan type mixer can also be used.

APPLICATION

Pour mortar after mixing. Ensure that air entrained into the grout is allowed to escape. When carrying out base plate grouting, ensure sufficient pressure head is maintained to keep mortar flow uninterrupted. Make sure that necessary form work is firmly in place and watertight. To achieve optimum expansion result, apply mortar as quickly as possible.

Grouting of machine beds
Pre-wet thoroughly, no standing water in bolt holes. If possible, grout anchor first, and the mortar bed in the second operation. Ensure continuous flow of mortar.

Grouting base plate
Prewetting for approx. 24 hours, no standing water. Maintain constant hydro-static pressure to continuous flow. Use steel rods or chain to make sure that all cavities are filled. Make sure that entrapped air can escape easily.
Grouting of large cavities / large volume
Depending on the volume to be filled and thickness of gap, large aggregates, e.g. 4–8 mm, 8–16 mm or 16–32 mm may be added to the SikaGrout®-214-11 HS mortar at a ratio of between 50-100% by weight of SikaGrout®-214-11 HS powder. Round aggregates are recommended while flaky ones should be avoided to maintain the workability and strength. 
As a rule of thumb, minimum thickness of gap to be grouted shall be 3 times max. grain size diameter of aggregate.
Addition of large aggregate and/or use of cold water will minimize temperature rise generated during early hardening period of SikaGrout®-214-11 HS. Always conduct trial in advance to test the workability and effectiveness in reducing temperature when using large aggregates and/or cold water.

CURING TREATMENT

Protect mortar surfaces from premature drying out by standard curing practice (keep moist, cover with wet hessian, use of curing compound e.g. Sika Antisol® E).

CLEANING OF TOOLS

Clean all tools and equipment with water immediately after use. Hardened mortar can only be removed mechanically.
