Next week we are starting a retaining wall project using 1 man basalt rock boulders. We have ordered 18 tons of the stuff to be delivered (in 2 or 3 seperate loads on different days). Only problem now is how to dump the rock safely. The street we are working on has a decent slope to it. And I think the rock will be fine in a pile once it's come to rest. But the challenge arises when the actual dumping will occur. I can see some of the boulders taking off and rolling down the street. We are trying to figure out a way to block the rocks from falling down the street. One idea was to park our trucks and trailers downhill and lower the ramps on the trailers. Then, the ramps would stop any rolling boulders. Problem there is they may also be damaged in the process. Another idea was to construct a retaining wall barrier of some sort. We also thought of just stacking strips of sod below where the rocks would be dumped. All of our ideas so far seem pretty lame. Anyone have any more ideas?
