Normally
engineers, building regulations or codes of good practice specifies what
strength of concrete should be used. If
no engineer has been appointed for the project, please contact one of our
technical staff.
Normally the
volume of concrete to be used will be the surface area multiplied by the
thickness of the structure (i.e. slab, foundation or beam). Note that provision for bulking and water loss
should be made when calculations are done.
Normally a time of one hour will be allowed for discharging
of a full load.
Due to the
nature of the product in terms of the different strengths and the short shelf
life of concrete, no unused concrete will be refunded. A dumping charge might also be levied when
concrete is sent back to the plants.
