SikaGrout®-215 NZ

High strength, shrinkage compensated, pourable cementitious grout

SikaGrout®-215 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. SikaGrout®-215 NZ has been designed to incorporate a two-stage process that counteracts the effects of shrinkage often associated with cement based grouts. These special materials provide positive expansion in the plastic phase and shrinkage compensation once hardened. SikaGrout®-215 NZ is normally used in details where the material can be confined and restrained during placement and curing to optimise these characteristics. SikaGrout®-215 NZ is a one component grout and only requires the addition of clean, fresh water.

SikaGrout®-215 NZ offers the following advantages:
  • Positive shrinkage compensation
  • High early age strength development
  • High final strengths
  • Excellent substrate adhesion
  • Adjustable consistency
  • High flow characteristics
  • Ideal for use in pre-packed aggregate systems of repair
  • Increased resistance to aggressive liquid penetration when hardened

Usage

SikaGrout®-215 NZ contains very fine natural aggregates. It is used as a high flow grout where dimensions are minimal. Typical applications for SikaGrout®-215 NZ are:
  • For gaps 2 mm to 80 mm
  • Grouting under base plates, tanks, etc., where dimensions are minimal
  • Grouting around pipe sleeves and liners
  • Grouting of rock anchors, tensioning cables, etc.
  • As the grout in pre-packed aggregate repair systems
SikaGrout®-215 NZ can also be used for:
  • Grouts for anchor bolts, ground anchors, rods, etc.
  • Reinforcement ducts in the connection detail between precast columns and beams

Application steps

MIXING

Application temp: +5°C to +25°C.  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®-215 NZ can only be removed mechanically.
