Basically i want to know the easiest way to build berms and small dirt jumps. I have been piling up logs and covering them with dirt to make some small ones, about 2 feet high but how do I make them bigger than that. Thanks

One key is measuring out the radius of the turn. This drawing shows 8 feet to the top edge. But, it could be 9 or 10 or whatever.


This is one of the first good berms I built:


I've also led trail volunteers to move dirt to build berms. It definitely goes fast when you have 3 wheelbarrows and a large group of people. You just keep dumping dirt along your line and packing and shaping. Damp dirt packs and shapes best.

If you want the jumps to last don't use biodegradable things in your dirt... meaning logs. Short term not to big of a deal. Long term your asking for problems.

Also to answer your question: digging, hardwork, time, friends who help & sweat.

I definitely agree with that . . . . but don't underestimate the manpower and time it takes to shape, pack, and put dirt in the correct place to start with.



Even small gradients screw up a spot. You can't take cookie cutter internet plans and put them on a spot and use heavy equipment to move all the dirt then expect guys to "polish" at the end. Each section must be ridden and tested before building the next!
