Unless you have a credit facility with us the most convenient method of payment is by credit or debit card. Alternatively we will accept payment by cash on or before delivery.
In normal ambient temperatures you will normally only have between 1 and 2 hours to place, level and compact the concrete and to finish the surface.
During the summer the setting time will be shorter at higher temperatures and you will need to ensure that enough manpower is available to place, compact and finish the concrete within about 40 minutes of the commencement of placing the concrete.
