Conditional Fill-Down Until Next Blank Cell

I need to automate a conditional fill down in excel. I have a sheet, some of the columns have rows of empty cells (the amount of empty cells varies). Whenever there is an empty cell I need to fill down, however when a new value is encountered that must then be filled down and so on. This bit I have as:

Set rngWBSv1 = Range("c2", Range("c65536").End(xlUp))
For Each clWBSv1 In rngWBSv1
If clWBSv1.Value = "" Then clWBSv1.Value = clWBSv1.Offset(-1, 0).Value
Next clWBSv1

Set rngWBS2 = Range("d2", Range("d65536").End(xlUp))
For Each clWBS2 In rngWBS2
If clWBS2.Value = "" Then clWBS2.Value = clWBS2.Offset(-1, 0).Value
Next clWBS2 ......................
