Hey, ive been digging for a while but Im starting my first "legit" bmx trails spot. I have the first set done but I'm having trouble with the second takeoff's structure. The dirt on the back and sides is not stable at all, it's always cracking and collapsing. I'll add nice moist dirt and pack it hard but it seems like the new added dirt doesent combine well with dirt thats already there. Almost like there's layers. The dirt is clayish and has some rocks. Any advice?
Thanks
Thanks
