EnviroHorn Installation & Servicing Guide
Installation of EnviroHorn is straightforward and shouldn’t take very long at all. For best results, EnviroHorn should be taped down to the road surface. This will ensure that all run-off passes through the filter. You may find it easier to apply flashing tape to the road surface on which to tape the down the EnviroHorn.
Before you start, then, you’ll need the following:
- Broom
- Knife or scissors
- Flashing tape & heat gun (if required)
- Adhesive tape – we recommend Gorilla Waterproof Patch & Seal Tape, Airtight Tape High Performance or any other tape of a similar grade. You will need approximately 3 metres of tape per EnviroHorn.
Installation Instructions
- Sweep road around drain to leave a flat and ideally dry surface.
- Some customers first melt flashing tape onto the road using a heat gun. This provides a dry, smooth surface onto which the EnviroHorn can be taped.
- Remove gully grid and insert EnviroHorn so that the printed panel lies flat on the road surface.
- Replace the gully grid.
- If necessary, trim the printed panel to leave a 6” collar around the outside of the gully, or to align with the flashing tape.
- Use an industrial waterproof tape to stick the EnviroHorn collar to the road surface. See recommended tapes above.
- If the road is cleaned by road sweepers, or scraped, we recommend instructing the drivers to avoid the EnviroHorns.
Emptying & Reusing EnviroHorns
- To empty a full EnviroHorn, remove tape then lift out EnviroHorn using the straps provided and empty contents onto a spoil heap. Alternatively, you could scoop sediment out while the EnviroHorn is still in the gully.
- Before replacing and reusing the EnviroHorn, we suggest rinsing the inside of the filter bag with a hose or watering can to clean the filter. This will prolong the use of the product.
- Refit the EnviroHorn and reseal to the road surface.
- EnviroHorns can be reused until the filter is clogged or it is too damaged to adhere to the road surface.
