We recommend a 3:2:1 concrete mix, sulphate resisting if necessary, 400x400x600mm deep for light - medium duty traffic over-run, assuming 'good' soil characteristics. For heavy duty service the foundation design may have to be altered depending on the soil characteristics.
In the cases of heavy duty usage CIS should be informed at the point of order placement so that necessary provisions may be made.
Extended root bollards should have at least 200mm of concrete below the base. The data is suggested only for non-specific applications as individual requirements and site conditions may dictate otherwise. Please refer to our Technical Department for advice in debatable cases.
Unless otherwise requested the bollard will not be in aluminium, although wherever possible we would recommend its use due to the ease of lifting. In any event we recommend that you select the optional 32mm diameter lifting out hole at 640mm above FFL and its respective galvanised steel lifting bar.
