When Gravel Bags are used in conjunction with Secure Covers, you're maximising the use of the Secure Covers system.

Secure Gravel Bags are specially designed to compliment the Secure Covers system. Their long cylindrical shape seals the edges of the stack or bunker and any overlaps of Secure Covers, preventing wind from  lifting the covers up.

As the Secure Covers are pulled taut over the silage, the Gravel Bags are placed around the edges, holding the covers in place. 

If you are placing multiple covers over your silage, the Gravel Bags run up and over the joins to prevent the wind picking them up.

If tyres are used, their circular shape doesn't always ensure an airtight seal. Many customers make use of their excess tyres when they swap over to the complete system, like this farmer.

If you choose to do this, please make sure there are enough tyres, as we cant guarantee the system being airtight.
