A thirty degree ramp in the rain with slippery clay coating it and very heavy loads of glug aren't my idea of a fun day, but that is what I had to deal with last week.
I was booked in to do this job that I hadn't been consulted on prior to starting. I understood that it was a basic small basement dig-out - simple enough. Builder had built for me a small ramp to negotiate the difference in heights, but turns out the truck to load was about 3.5m above where I was digging out...and it was no small ramp! To overcome the slippery, steep conditions I used my home-made grip sheets on top of the ramp to give traction. Still scary. Thankfully the builder had added rails to the side of ramp to improve safety.
Some pics, but they are taken before the weather turned to custard. The angles don't really show how steep it was.
