SikaGrout® HES NZ

High early strength, shrinkage compensated, pourable cementitious grout

SikaGrout® HES NZ is a cementitious grout containing a carefully formulated blend of natural aggregates and other materials, plus Sika admixtures, which enable it to achieve high early age strengths. It contains materials that provide positive expansion in the plastic phase and shrinkage compensation once hardened. SikaGrout® HES NZ is used in details where the material can be confined and restrained during placement and curing to optimise these characteristics. SikaGrout® HES NZ is a one component grout and only requires the addition of clean, fresh water.

  • Positive shrinkage compensation
  • High early age strength development
  • High final strengths
  • Excellent substrate adhesion
  • Adjustable consistency
  • High flow characteristics
  • Controlled bleeding and segregation while plastic

Usage

SikaGrout® HES NZ is ideal for many types of structural grouting applications. It can be mixed at different stages of fluidity to produce the desired level of workability. Add the required amount of water for:
  • Rammable dry pack material
  • Trowel applied medium flow mortar
  • Pourable high flow grout
Typical applications for SikaGrout® HES NZ are:
  • Under machine foundations and base plates
  • For gaps 15 mm to 80 mm
  • Grouts for anchor bolts, ground anchors, rods, etc.
  • Reinforcement ducts in the connection detail between precast columns and beams
 

Advantages

  • Positive shrinkage compensation
  • High early age strength development
  • High final strengths
  • Excellent substrate adhesion
  • Adjustable consistency
  • High flow characteristics
  • Controlled bleeding and segregation while plastic

Application steps

MIXING

Application temp: +5ºC to +25 ºC. Pour the required amount of clean, fresh water into a suitable mixing container and slowly add all of the powder while mixing continuously with a Sika mixing paddle attached to a low speed electric drill (max. 500 rpm). Mix for 2-3 minutes until a smooth, lump free consistency is achieved.

APPLICATION

Grout should be placed into forms immediately after mixing, taking care to ensure no air is trapped.

CURING TREATMENT

Formwork should be left in place for at least 5 days if possible, to prevent moisture evaporation and provide restraint to early age hardened expansion. Once formwork is removed the use of a suitable curing membrane such as Sika Antisol® should be applied to any exposed faces. Refer to separate data sheet for further information.

CLEANING OF TOOLS

Clean all tools and equipment with water immediately after use. Hardened SikaGrout® HES NZ can only be removed mechanically.
