Laying a brick slip boarder
I have some brick slips which I am going to use to lay an edging to my boarders. I know I should be digging out a trench to lay the slips in but I am unsure what I should be laying the slips onto, can I just use sand or should I use sand and cement, do I use sand and then use a product to put in the gaps ? As I,m sure you can gather I am a bit of an amateur so any advice gratefully received.
Thank you !
