How should I prepare the clamp?

• Clean out any old silage and, if necessary, pressure wash.
• Ensure effluent channels are not blocked
• Repair the walls and base, sealing any cracks properly – remember, heavy clamp machinery running close to silo walls exerts enormous pressure on the walls.
• Remove nails, old sealing materials and any other uneven obstructions from the walls.
• Cover any rough areas of the wall with bags to prevent damage to the main sheeting.
• If the silo walls are constructed of sleepers, porous concrete or earth they should be lined completely with polythene.
