"Tried these for a job where I couldn't use ladder board and sandbags if no-one could hold ladder at eg apex of roof. These mats are great for uneven surfaces and I soon found I was using them automatically for every surface wet or dry, flat or uneven.
"This is a great product. Had mine a couple of months and its great for use on - uneven ground - sloping ground - grass - tarmac/concrete/paving Basicly it gives extra grip, stops the ladder feet sinking into soft ground and lets you adjust for sloping ground by flipping mats from one side to another. Use 2 mats either side for flat ground, 1 mat one side 2 the other for sloping ground and 1 mat/3mats for more severe slopes. Google laddermat to see some videos how this can be used."
