Solution to boggy clay path?
I watched DIY sos the other night,the one where Chris Beardshaws chelsea garden was transplanted onto the roof at GOSH. They used some sort of underlay,for want of a better word,that looked like rows of black toblerone,covered it with shingle and put pavers on it.
I have a boggy area in my allotment that is getting worse with each visit as we walk on it.
Can anyone tell me what they used and if it would work if i dug out the clay,put some of this underlay thingy in then stones and finally replace the paving stones which i took up to put woodchip down.
