Althon manufacture mammal shelves and mammal ledges in GRP, HDPE and Stainless Steel for installation into new, existing culverts or concrete pipes.

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

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