The National Trust chose Arch‘s Tanalith E wood presevative to protect the rebuilt footbridge which carries over 300,000 people a year across the falls.
Arch was called in by the Trust when it was thought that the bridge would be exposed to high levels of moisture when in ground contact, which could shorten the life span of an untreated wooden structure.
The bridge was rebuilt by the Royal Engineers using larch and spruce timbers, high-pressure treated with Tanalith E from the National Trust’s facility at Coniston.
