• Forced action and truck mixers should be free from all contaminants prior to the batching of concrete containing Sika® Watertight Concrete Powder.
• Sika® Watertight Concrete Powder should be added to the mixer at the recommended dose (1 bag per m3) prior to the batching of concrete.
• Batched concrete mix constituents should be subsequently batched on to the Sika® Watertight Concrete Powder in accordance with Sika® mix design recommendations.
• Additional mixing water should then be dispensed to bring the concrete to the desired consistence.
• On completion of the batching procedure the concrete load should be mixed in the truck mixer/agitator on full revolutions for a minimum of 5 minutes to ensure that the optimum consistence has been achieved.
• The w/c ratio and consistence control remains the responsibility of the concrete producer. Laboratory trials are recommended to evaluate and confirm the actual water reduction.

• In the event of part loads <1.0m3 it is recommended that a 1m3 dose of Sika® Watertight Concrete Powder is used
