Amphibian Slot Tunnel
Introduction to the system

The ACO Amphibian Tunnel (Slotted) AT 500 is a slotted one-piece tunnel system designed to protect amphibians during migration to their spawing grounds.

It has a slotted upper surface to provide optimum climatic conditions and adaption of temperature. The system is manufactured from polymer concrete and is certified to BS EN 1433:2002 Load Class D 400.image

The ACO Amphibian Tunnel AT 500 with slotted upper surface is installed within the road structure, flush with the road surface. The advantages of this system are particularly apparent in problem terrain conditions, such as where there are ditches on one or both sides of the road or if high ground-water levels prevail.

The proven benefits for amphibians and small animals is easily explained: installation flush with the road surface permits a minimum crossing distance, uncomplicated entrance areas at road gutter level, optimum climatic conditions due to the ingress of water and air and, at the same time, optimum adaptation of temperature to the ambient conditions.
