RECESSED MOUNTING
E
The calculation is based on the hole into which the lighting column is planted being back-filled with the excavated material or material of better quality. The following should be specified to the installer: a) all back-filling material is to be placed in 150 mm thick layers and be well compacted; b) during compaction, care is to be taken to ensure that the corrosion protection system of the lighting column is not damaged; c) when the hole is back-filled with concrete, the concrete is to extend from the base of the lighting column to ground level; d) where paving or bituminous surfacing is to be applied around the lighting column, the top level of the concrete may be lowered by the thickness of this surfacing; e) a duct with the same dimensions as the lighting column's cable entry slot is to be formed in the concrete using a suitable preformed lining tube.
