FloGuard 100mm Pack of 10

Tried these out but they wouldn't stay in place and just slithered around. The wind can easily lift them out.

this is very easy to fit left it to my 16yr old to do keep him busy. It did need some trimming to fit which was also easy I used under the drainage grill in my block paving to stop leaves getting underneath its doing a great job i did have to buy some cable tie to connect one length to another for extra security

Its a bit fiddly to install but once in place works a treat. Easy to cut to length with a sharp knife, then use the remainder on the next run. I bought mine from Screwfix, less than £8.00 a pack, even cheaper if you buy 5 or more packs.
