I'm new to digging and wondering if I could get a advice on building simple structures like berms, jump ect. If anyone can help it would be greatly appreciated.
The way I started building berms is just to get some rocks (big) and put them round a corners then pack soil over them so there completely covered. The rocks will help with the strength over time adm will allow water to pass through the berm without making it soggy wen it rains. Hope this helps.
Like Ben said, start of with big stuff at the bottom and then when you get nearer to the surface of your feature use looser materials like dirt so it fills in all the cracks
First I go and scope out where I want the trail to go. Looking for features like big rocks or fallen trees alway's make for cool features.
Then mark those features with something so you can find those later.
Then go through and clear the trail path. (Trees, Brush, Stumps)
Once the trail is laid out, then start making your features
If you are in a area that does not have a lot of good dirt or easy digging dirt, I like to use logs and sticks as jump and berm filler. Rocks work great too but those tend to get heavy after a while depending on the size of the feature.
Here is a video of one of the first trails I started building
for berms, you half dig down, and use that dirt to put on the ground. minimal waste, and it lets you pump down into the ground and the corner.
for jumps, you need to take your time. if you want it finished quick, use stick and logs as a filler, but it wont last as long. if you take your time, just pile dirt, pack it, pile more, pack it.
