ive been cleaning this house with decking for over a year now. the decking looks newish and not green so i never worried about ladderslip till yesterday i put my ladder up and just tested it before i climbed as you do. my ladder slipped away as easy as anything!
bending down to look at it closer i realized the decking isnt wood at all,but some kind of artificial plastic . my ladders have spikes fitted on them but they werent digging in the decking whatsoever . ive been very lucky that i havent fell in the past on this surface and surely will never use my ladder on it again
moral is -dont assume that decking is made of wood
