Has anybody tried using concrete powder on dirtjumps?
Our spot gets heavy use and the jumps frequently get torn up, we are sick of rebuilding all the time.
I found this pic and got inspired:

Buy a small bag of concrete mix - in powder form. Make sure your lip is in the final shape you want it and that it is firm and dry. Next, mist the lip completely with water and throw the dust onto the jump with a cup. Make sure its an even spread of the concrete dust and mist again evenly. Use spade to smooth out the layer of wet concrete. Let it dry and repeat this process until your happy.

I dont think it would last, I would expect it to crack when the earth underneath moves. Neat cement is not good for that

You would be better off making a stack of rubble and pouring a proper mix of concrete over it 6:1 mix with ballast.
then render it with some 3:1 with sand to get a final shape.

using some chicken wire or similar to reinforce it will make it pretty much unbreakable.
