Air-filled flotation devices can replace expanded polystyrene (EPS).


There are already a number of products on the market that provide a more weather-resistant alternative to foamed polystyrene floats.


For examples, see the links below...

Located in Campbell River, this company manufactures floatation for aquaculture industries without the use of expanded polystyrene. They aim to provide more sustainable products to the aquaculture industry.

Located in Campbell River and 100 Mile House, this company manufactures multiple polyethylene products, including floating structures such as docks, pontoons, and more. The products are made of air-filled polyethylene resin, making them both durable and resistant to environmental weathering.

Located in Surrey, this company uses air-filled HDPE pipe as floatation for docks. Unlike polystyrene, this pipe is resistant to weathering, as it has been designed to withstand challenging environments. 

Upgrading to Air-Filled Flotation is estimated to cost  $1,000 per flotation raft, roughly 4x expanded polystyrene (EPS).

Despite the cost to upgrade, there are many benefits that result in cost savings in the long term, including:
  • longer product life
  • more robust flotation device
  • weather resistant
  • fewer ongoing repairs
  • fewer repeat installation fees
  • less pollution

Do you know of a sustainable alternative to expanded polystyrene floatation?

We'd love to hear from you!
