SUBSTRATE QUALITY
Concrete
The concrete must be structurally sound, thoroughly clean, free from oil, grease, dust, loose material, surface contamination and materials which will impair the grout flow or reduce adhesion strength. Laitance, delaminated, weak, damaged and deteriorated concrete, and where necessary sound concrete, must be removed by suitable mechanical preparation as directed by the engineer or supervising officer. Any pockets or holes for structural fixings must also be thoroughly cleaned of all debris.
Shutter Formwork
Where formwork is to be used, all formwork must be of adequate strength, treated with release agent and sealed to prevent leakage of pre-wetting water and grout. Ensure formwork includes outlets for removal of the pre-soaking water. As a guide, leave a gap of approximately 150 mm on one side and 50 mm on the opposite side.
A header box or hopper should be constructed on one side of the formwork so that a grout head of 150 to 200 mm can be maintained during the grouting operation.
MIXING
Drill and Spiral Mixer
Pour the correct amount of water into a suitable clean mixing container. While stirring slowly with drill and spiral mixer (200 to 500 rpm), add the complete bag of powder into the water. Mix continuously for 3 minutes to achieve a uniform and lump free, smooth consistency. Do not add more water than the maximum specified.
Grout Mixer
SikaGrout®-212 Fluid must be mixed using suitable grout mixing equipment combined with agitator for continuous large volume mixing. The volume capacity of the equipment must be applicable to the volume of material being mixed for a continuous operation. Equipment trials must be considered to ensure product can be mixed satisfactorily.
Pour the minimum water ratio in the correct proportion into the grout mixer. While stirring the water, slowly add the powder to the water. Add more water within the mixing time up to the maximum allowed until the desired consistency is achieved.
Mix continuously for a minimum of 3 minutes. For larger mixes, the mixing time must be extended to approximately 5 minutes (or as necessary) until the grout achieves a lump free, smooth consistency. Do not add more water than the maximum specified.
Note: Do not use continuous mixing equipment.
APPLICATION
Reference must be made to further documentation where applicable, such as relevant method statement, application manual and installation or working instructions.
Pre-wetting
The prepared concrete substrate must be thoroughly saturated with clean water for a recommended 12 hours before application of the grout. The surface must not be allowed to dry within this time. Prior to application of the grout, all water must be removed from within formwork, cavities or pockets and the final surface must achieve a dark matt appearance (saturated surface dry) without glistening.
Placing
Apply the material shortly after mixing to take advantage of the expansion properties. Immediately after mixing, pour or pump the mixed grout into the header box or hopper, ensuring continuous grout flow during the complete grouting operation to avoid trapping air.
For large volume placement, grout pumps are recommended. Equipment trials must be considered to ensure product can be pumped satisfactorily.
Surface Finishing
Finish exposed grout surfaces to the required surface texture as soon as the grout has started to stiffen. Do not add additional water on the surface. Do not overwork the surface as this may cause surface discolouration and cracking. After the grout has initially hardened, remove formwork and trim edges while concrete is ‘green’.
Cold Weather Working
Keep bags in a warm environment 48 hours prior to use. Consider using warm water to assist with achieving strength gain and maintaining physical properties.
CURING TREATMENT
Protect the fresh material from premature drying and cracking using an appropriate curing method (e.g. curing compound, moist geo-textile membrane, hessian, polythene sheet, etc.). In cold weather, apply insulated blankets to maintain a constant temperature to prevent surface damage from freezing and frost.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened and cured material can only be mechanically removed.
