Process and Materials
At Melgrand we manufacture all products in Australia and utilize various materials and production methods
In this process a carefully controlled mixture of washed river sand, cement, fines and polymers is mixed with a limited amount of water until it achieves a damp malleable state and can be compressed either by hand compaction or by a small mechanical ram-tool.
Then after an initial curing period of around 12 hours the element is removed from the mould and kept in a humid environment for at least 24 hours. Full curing is not achieved until 28 days at which point the element is carefully packed for delivery.
Wet cast concrete is a flow-able form of concrete which is poured from a mixer or hopper.
Wet cast concrete is often used in the precast industry, where it is cast in forms and stripped, finished and marked prior to shipping.
At Melgrand the wet cast method is often used for larger pieces and more complex shapes, which need flow-ability in the concrete in order to consolidate around reinforcement and throughout the form.
Wet Cast items are usually sufficiently cured for delivery after 7 days.
