SikaGrout®-212

The prepared grout may be pumped or transported to the forms in buckets or wheelbarrows and deposited without delay. External vibration and agitation of the grout in the forms are permitted. Grout having been prepared but not placed within one (1) hour after preparation shall be discarded. Prepared grout shall be agitated until use. Several hours after placement of grout (depending on ambient temperatures) forms may be removed and exposed grout shoulders may be trimmed or shaped to desired finish.

All grease, oil, laitance, ice or snow and any foreign deposits shall be removed from all surfaces with which the grout will come in contact. The concrete foundation shall be roughened to the extent that it does not present a smooth surface, which would impede the bond of the grout to the foundation. All dust and loose particles shall be removed by sandblasting, high pressure water blasting or other suitable means. Concrete foundations less than 28 days old shall be kept wet for at least 12 hours, and older foundations for a minimum of 24 hours before placing grout (SSD condition). All free-standing water shall be removed from concrete surfaces prior to grouting. All items to be grouted into place shall be properly positioned and anchored prior to grouting except for anchor bolts and dowels, which may be placed into the fresh grout if job conditions permit and at the discretion of the engineer in charge. For grouting of base plates the formwork used to contain the grout shall be constructed in a workmanlike manner and caulked to prevent leakage of grout. Provisions shall be made at the high points for air to be vented as it is displaced by grout.

For application greater than 150 mm (6 in) in thickness, add up to 12 kg (26.5 lb) of 10 mm (3/8 in) coarse aggregate. The aggregate must be non-reactive (reference ASTM C1260, C227, and C289), clean, well-graded, saturated surface dry, have low absorption, high density and comply with ASTM C33, size number 8 per table 2.

Mix using a heavy duty low-speed drill (300 - 450 rpm) and mixing paddle (Jiffy or Exomixer®) or in a grout mixer. The size of the mixer should be appropriate to the volume of grout required. Use a minimum amount of water consistent with placeability requirements. After all dry product has been added to the water, continue mixing for three (3) minutes.

Minimum application thickness (neat without additional aggregate) is 25 mm (1 in), while the maximum application thickness (neat without additional aggregate) is 150 mm (6 in). Thicker applications are possible with the addition of suitable aggregate. 

Maintain wet grout, ambient and substrate temperatures between +5 °C and +32 °C (41 - 89 °F) for a period of 72 hours after placing, unless using Sikacem® Accelerator in mix (refer to Technical Data section).

For best results, condition product to temperatures ranging from +18 to +29 °C (65 to 84 °F) prior to mixing and installation. Lower temperatures may result in slower strength development and longer cure times. 

Initial set time is 4 h to 5 h 30 min, and the final set is 5 to 7 hours.

Reducing water content accelerates strength development and ultimate compressive strength values.

Just add water, mix, and place. 

SikaGrout®-212 is a non-metallic and non-corrosive cementitious grout that contains no chlorides and may be placed at various consistency ranging from dry pack to fluid by simply adjusting the quantity of mixing water.

4.6 L (1.21 US gal.) water/bag max.

Approximately 13 L (0.46 ft3) per bag of fluid grout.
