SikaGrout® Deep Pour must be mechanically mixed using a mechanical grout mixer and suitable mixing container. It is recommended to mix a full bag in clean container using an electric drill / spiral drill and spiral mixer at a speed of approximately 500 rpm.

Pour the correct amount of water into a suitable clean mixing container. While stirring slowly with drill and spiral mixer, add the complete bag of powder into the water. Mix continuously for 3-5 minutes to achieve a uniform and lump free smooth consistency.

Do not add more water than the maximum specified.

SikaGrout® Deep Pour can be placed by gravity flow or by pump. It is essential that proper placing on the job site is practised to ensure placement is completed without problems. Sufficient labour, grout and equipment must be present to ensure continuous placement.

Gravity Flow

Mixed grout should be poured one side of the void to avoid air entrapment. Grout is best poured over short distances to ensure this. Use a suitable header box, maintaining the grout head at all times to ensure continuous flow. To facilitate grout compaction and top plate contact, use rodding, tamping or flexible strapping in short strokes while maintaining an adequate head of grout. Do not vibrate as this will cause segregation. Any adjacent machinery or equipment causing vibration should be shut down until initial set (5-6 hrs).

Pumping

When pumping SikaGrout-Deep Pour, ensure the pump is suitable for the grout consistency and for the distance and height it is to be pumped. A positive displacement pump is recommended. Place grout by pumping into the farthest corner, filling the space gradually. Ensure that air is not entrapped under the base plate. Maximum aggregate size is 5mm. Ensure that selected pump is suitable for pumping this size of aggregate.

Suitable curing methods such as plastic sheet, wet hessian, liquid membrane etc. must be used to protect the freshly applied grout from the drying effects of sun and wind. Curing must commence immediately after placement, and continue for at least 7 days. Curing is vital to the ultimate performance of grout as it allows optimum strength development and ensures tight contact with the baseplate.

Clean all tools and application equipment with water immediately after use. Hardened material can only be mechanically removed.
