The surface should be sound, clean, free from loose material, grease, laitance, dirt curing compound, etc.
Wet the substrate to achieve a saturated and surface dry condition prior to application of Vetogrout CG511.
Erect hopper system and form-work, make sure that the shuttering is watertight by use of a polyurethane sealant such as Vetofl ex PU780 or a rubber gasket seal. This step is important to insure no cement paste and
water leak from the shuttering. Contact your Saveto’s local representative for more technical information, Saveto’s grouting detailed method statement, and CAD details
It is essential that the base plate is clean and free from oil, grease or scale. Air pressure relief holes should be provided to allow venting of any isolated high spots. If leveling shims are used and are to be removed after the grout has hardened, they should be treated with a thin layer of grease.
Unrestrained Surface Area
Generally the gap width between the perimeter form-work and the plate edge should not exceed 150 mm on the pouring side and 50 mm on the opposite side. It is advisable where practical to have no gap at the flank sides.
Low temperature working
When the air or contact surface temperatures are 5ºC or below on a falling thermometer, warm water (30 - 40ºC) is recommended to accelerate strength development. For ambient temperatures below 10ºC the grout consistency should be flowable and the form-work should be maintained in place for at least 36 hours. Normal precautions for winter working with cementitious materials should then be adopted.
High temperature working
At ambient temperatures above 35ºC the mixed grout should be stored in the shade Cool water (below 20ºC) should be used for mixing the grout. Vetogrout CG511 is alkaline and should not come into contact with skin and eyes. Avoid inhalation of dust during mixing. Gloves, goggles and dust mask should be worn.
