Usage

SikaGrout®-900 (HGG 100) can be used in all grouting situations where shrinkage is undesirable and high grout strength is required. Primary uses for SikaGrout®-900 (HGG 100) are : bedding, filling and grouting applications where complete filling of voids with a high strength non-shrink material is required.   It can also be used for spiral connector and underplate grouting, repairs to precast concrete, bedding bearing plates, anchor bolt fixing, cable grouting and crane rail assembly.

Advantages

  • High flowability characteristic.
  • Consistent quality as all ingredients are premixed in the factory.
  • High early and ultimate strengths.
  • Eliminates shrinkage and bleeding
  • Increased strength when fully restrained.

Application steps

SURFACE PREPARATION

All surfaces must be cleaned, and free of oil, dust, dirt, paint, curing compound etc. Thoroughly damp all surfaces before starting and keep in a moist condition during placing.

MIXING

Dampen the electric mixer blades with water prior to mixing the initial batch of SikaGrout®-900 (HGG 100). Ensure that the mixer is free of standing water.

First pour 80% of the volume in a clean mixing container. Slowly add the powder & mix continuously to uniform consistency. Add the balance amount of water while continuing to mix for 3 to 5 minutes until a homogeneous consistent grout is achieved.

APPLICATION

The formwork shall be constructed to be leak-proof by using foam rubber strips or mastic sealant beneath the constructed formwork and between joints. After mixing, stir lightly with a spatula for a few seconds to release any entrapped air. Pour the mixed grout within 10 – 15 minutes after mixing.

 

Grouting Large Volumes

For grouting thickness greater than 50 mm, the addition of clean well-graded 10 mm aggregates is recommended to reduce temperature rise. As a guide use a maximum of one part aggregate to one part of grout by weight. Conventional concrete pan mixers and pumps can be used for mixing and placement. A site trial should be conducted to determine the appropriate ratios of grout, aggregate and water.

CURING TREATMENT

Immediately after finishing, exposed area should be thoroughly cured with water, or curing compound.
