The surface onto which the grout is to be applied should be scrabbled to remove laitance and expose aggregate. Do not use bush hammers or similar preparation equipment that can crush the aggregate but leave it in place. The surface must be free of oil, dust, dirt, paint, curing compounds, etc. Soak area to be grouted with water for 24 hours prior to grouting to minimize localized absorption and to assist in the free flow of the grout. Surfaces should be damp but free of standing water.
Particular attention should be paid to bolt holes to ensure that these are water-free. Use oil free compressed air to blow out bolt holes and pockets as necessary.
Base plate, bolts, etc. must be clean and free of oil, grease and paint etc. Set and align equipment. If shims are to be removed after the grout has set; lightly grease them for easy removal.
Ensure formwork is secure and watertight to prevent movement and leaking during the placing and curing of the grout. The area should be free of excessive vibration. Shut down adjacent machinery until the grout has hardened.
In hot weather, base plates and foundations must be shaded from direct sunlight. Bags of grout should be stored in the shade prior to use.
In cold weather, the temperature of base plates and foundations should be raised to >10°C.

In hot weather use cool water to bring the mixed grout temperature to <30°C.
In cold weather use warm water to raise the mixed grout temperature to >10°C.
Damp down the inside of the grout mixer with water prior to mixing the initial batch of SikaGrout®-951. Ensure the mixer is damp but free of standing water. Add the pre- measured quantity of water. Slowly add the
SikaGrout®-951, mixing continuously. Mix for at least five minutes until a smooth, uniform, lump free consistency is achieved.

Lengths of metal strapping laid in the formwork prior to placing may be necessary to assist grout flow over large areas and in compacting and eliminating air pockets. Pour the grout continuously. Maintain a constant hydrostatic head, preferably of at least 15 cm.
On the side where the grout has been poured, allow 10 cm clearance between the side of the form and the base plate of the machine.
On the opposite side allow 5-10 cm clearance between the formwork and the base plate.
SikaGrout®-951 is suitable for use with most types of pumping equipment.
Immediately after SikaGrout®-951 is placed, cover all exposed grout with clean damp hessian, and keep moist until grout is firm enough to accept a curing membrane.
Should the grout shoulders require finishing work, this should be carried out prior to application of the curing membrane.
