Concrete Process

Firstly, ensure your concrete pump has a 50mm rubber hose. Same type used for filling block masonry walls.           

A 50mm hose can be closed off simply and handled easily

Secondly, your concrete pump should be able to reach to the furtherest corners from one location. There should be enough room behind for the Concrete aggitator to discharge safely into the concrete pumps hopper. Also allow enough room for the outriggers of the concrete pump to bear on solid ground

Concrete as specified by the Project Engineer. ZEGO recommend 32mpa 10mm agg max 180mm slump. ZEGO also recommend the use of ZEGO Cellflow Click here for more info

Ensure that no additional plasticizer is added to the concrete when using Cellflow.

When pumping concrete into the ZEGO walls, please follow the OH&Safety guidelines below;

1. First pass of concrete one course level = 300mm NOTE: Do not pour over lintels!
2. Second pass of concrete no more than 900mm above the last level NOTE: If it has been less than one hour from the last pass you should not pour any more than 300mm above the first pass
3. Third pass of concrete same as above
4. Fourth pass of concrete same as above
5. Pour the lintel in one pass followed by the bond beam level
6. Your last pass of concrete is best to be only 300mm so that the concrete does not sink
7. Level off for top plate bearing and top up with trowel and bucket and insert holding down bolts at appropriate centres
8. If you are setting up for a slab then level off and insert starter bars for slab
