I have just finished paving in a 3x3m section of my L-shaped vege garden to reduce the size of the vege garden. 3 sides of the paved area are locked in by previous paving however 1 side is open to the garden. In terms of locking that side in I have seen that I should cement it in at an angle to below the road base that I put in. I brought Westbuild 20KG sand and cement for this as I was also going to use it to sweep in between the pavers. My question is 1: Is this product ok to put in between the gaps in the pavers or should I just use normal brickie sand and 2: Is this ok to use to edge off the paving section or should I get some plain cement ? Any help is appreciated.
