    Laitance can be reduced by controlling the amount of water in the concrete mix during construction. If too much water remains in the concrete than various other issues can be found like greater shrinkage with the possibility of more cracks and reduced compressive strength overall.

    Mac-arthur piles are the heavy steel casing with a core is driven into ground. When the desired depth is reached, the core is withdrawn and a corrugated steel shell is placed in the casing. The last operation consists in filling and gradually compacting the concrete and withdrawing the casing.
