question on using sand bags to sink brush I

I have always used buckets with concrete in them . do you have trouble getting brush to stand up in the water,

have to admit never tried that 1... simple easy and cheap ! should work...

I have not tried it, but have plans to. I would imagine that the brush would lay down once it got waterlogged. I have been wrong before though.

I never worry about brush standing up . Use anything to hold it down in place . if it has limbs they will hold it up .
