The Steinhardt® HydroSac is a cost-effective method of trapping pollutants such as leaves, twigs, etc. and preventing such debris from entering drainage channels where expensive blockages can be caused.
The easy-to-change net comes in various mesh measurements (2/3 and 2-4 mm) – HydroSac can be retrofitted in practically all situations.
Maintenance could not be easier – inspect the net now and again, depending on the current weather situation. If necessary, the sack should be removed and emptied.
