Additives with water to make dirt jump harder/last longer???

[morvo11]

i just had a dozer over at my house and made a killer six pack. I was just curious though. When i was up in whistler while there were making the red bull jumps. i talked to some of the guys and they had a mixture with water to help the dirt harden and hold together better. i was wondering if anyone had any recomondations about it. thanks..

Wood glue works great. My buddy Hacksaw told me about it, and it works killer on my DJ's. Mix it with water in a pump sprayer, and apply to lips and landings. You can pick up a gallon for about 13 bucks.

I know when they build thoes giant sandcastles they use a mixture of regular white glue [elmers] and water.

There is always sackrete... if you are having rain problems covering the lips with old carpets works good...

[opjones]

yeah old carpet works good, it'll let them firm up

glue doesn't seem like a good idea if you live where it rains alot....(like Seattle)

yea which is where i am at. however i could have sworn that it was a agricultural mixture from like a lawn store. im goin down to a place to ask them about it.

different dirt packs differently. clay packs really really well. I don't know if you've been to greenlake but those jumps become cement.

that dirt is the red clay used for soccer fields. Top soil, I've heard, packs well too.
