I started with the groundwork and a mallet. Filling it with dirt and stones i found around the property and the local creek. Did everything via eye measurement but that wont hurt nobody.
Followed by a screed matt and the coping my grandpa welded for me. The base had to be digged out 20cm and filled with stones as well, which was a hell of a work since i only had a bucket and two arms. That was actually the most workload involved besides mixing the ton of concrete by hand.
I put a base layer of screed followed by a top layer of fine cement. I used a wood trowel to bring it in rough shape and finished with a metal one to close the pores.
All it needs now is a protection layer and it is ready to skate.
Unfortunately I had no photo camera with me to take more pictures. But my friend Peat gave me a contour camera which i randomly put on the side when i had the muse for it. You can watch the moving pictures that came out below in this more or less shitty edit I made on movie maker.
Thanks to everyone involved.
