Wood lagging

Wood lagging is a method of banding wooden slats around pipelines to protect against impact, abrasion, and corrosion.

The latter, constructed in 2007, used wood lagging in the environmentally-sensitive terrain and river crossings of Alberta's Jasper National Park.

[2] Wood lagging involves wiring a series of wooden slats together to create a 'blanket'.

This blanket of wooden slats is then dropped over and wrapped around the outside of a pipeline, with or without coating,[4] and secured with steel or plastic banding.

[2] Materials for wood lagging can often be sourced regionally near pipeline construction sites, reducing transportation time and costs.
