Althon manufacture mammal ledges in HDPE for installation into concrete pipes. 

Mammal Ledges allow animals such as badgers, otters and other wildlife to pass through culverts, pipes or under bridges reducing the risk of drowning in the culvert or river.

Our HDPE mammal ledges are durable, lightweight and easy to install with non – slip surfaces. CAD and PDF download drawings are available from the website. Our mammal ledges can be combined with our precast headwalls at the end of culverts. Please contact us for design assistance and pricing.
