Filling track hoses

[chuckie stella]

Hi,

Our club currently use mainly sand filled hoses. These were stored somewhere damp so now the sand has moisture in it which makes them extremely heavy. We have recently filled a few new hoses with plastic injection moulding pellets which worked exceptionally well, however extremely expensive.

Does any know where we can purchase a large amount of pellets or re-grind cheap?

Or, any other ideas on what to fill the hoses with to keep the price and weight reasonable?

Thanks in advance,

Matt
