Application

Preparation

Formwork should be erected and made grout-tight. The formwork must be designed with sufficient hydrostatic head to ensure grout flow into and across the grouting area. Saturate the grouting area with water. Leave for 1 hour and then blow out any surplus water.

Mixing

Pour 4.5 litres of clean water into the mixing vessel for each complete bag of CS Grout to be used. Slowly add the powder to the water whilst continually mixing. Mechanical mixing should be carried out using either a high torque slow speed drill with a Grout Stirrer or a grout mixer set on slow speed. (High speed or colloidal mixing will cause thixotropy leading to loss of flow.)

Each 25kg bag of CS Grout will yield approximately 13.25 litres of mixed grout. Each 25kg bag of CS Grout plus 25kg of 6mm aggregate will yield approximately 22 litres of mixed material.

Placing

Grout should be placed within 20 minutes of mixing. Continuous placing is important, pouring from one side of the formwork until the grout appears at the opposite side of the grouting area. Do not disturb once grouting has been completed. CS Grout may be placed at temperatures between 5°C and 45°C.

Curing

Placed grout, which is exposed, should be cured in accordance with good concrete practice including water spray or the spray applied curing membrane Polycure.
