About a month into lockdown I did some DIY and used 2 very thick rubble sacks for the results of the destruction.
They have been sitting in the garden untouched since but today I though it may be a good idea to dispose of them the local tip. The bags looked intact before I tried to lift them but then they turned into that kind of confetti once seen with the carrier bags supplied by Tesco. Obviously the UV had got to them but very thick rubble bags left in the sun for a couple of months should have lasted a bit longer!
