Surface Preparation
Substrate
All contact surfaces must be free from oil, grease, standing water, or any loosely adherent material. Cut back concrete surfaces to a sound base. All dust must be removed, and bolt holes or fixing pockets should be blown clean of dirt or debris.
Steel Surfaces
All steel surfaces should be shot blasted to remove rust and flaky mill scale. Protect cleaned surfaces by applying Vetoprime EP491.
Form-work
The form-work should be constructed to be leak-proof, as Vetogrout EG340 is free-flowing. Loss of grout once the material is placed but not yet hardened will result in incomplete filling of the gap. For free-flow grout conditions, it is essential to provide a hydrostatic head of grout. To achieve this, use a feeding hopper system.
For inaccessible deep-section placing, use extended-width chains to encourage lateral movement and fill the gap completely. This will help eliminate air pockets. For further information and specific advice, please contact Saveto.
Mixing
Pour all the contents of the hardener pack into the base container. Mix using a slow-speed power mixer until homogeneous. Pour all the resultant liquid into a container with a capacity of 20-25 liters. Add all the filler provided for the product. Mix using a slow-speed power mixer for two minutes or until a uniform color is achieved.
Placing
The mixed grout should be poured steadily from one side only to eliminate the entrapment of air Continuous grout flow is essential.
Ensure sufficient grout is available before starting.
Regulate the time it takes to pour a batch to the time taken to prepare the next batch.
