i put my ladder up today on the surface in the photo (quarry tiles) using a laddermat as my safe surface . if you dont know ,laddermat is 4 square pieces of spikey rubber matting
Anyway up i go on the ladder ,starts cleaning the upper window and WHOOSH ladder slips out on me and down i go !
by sheer luck i landed not too badly and seem to have got away with a painful ankle and a bent rung on my ladder . My ladder was placed properly and the gravel in the photo is only scattered from after my fall
on LADDERMATS own video ,it shows it being set up on quarry tiles , BUT DONT DO IT !!!!!!!!!!!!
