Environmentally Friendly. Maintenance Free. Timeliness.

In excess of 2000 Beaver Proof Add Ons have been installed and tested and are operating maintenance free. 

The Beaver Proof Add On is a patented environmentally friendly solution made from a wide variety of different sized culverts. With ingenuity, it's design has become environmentally friendly and nature safe. It allows for fish passage, water flow and weather changes. The Beaver Proof Add On can be installed on existing culverts as well as with new culvert installation in road systems, railways, dams and anywhere beaver is an issue. By using the Beaver Proof Add On with new grade construction, you have eliminated the problem before it has started. 

Installation is the key!

When doing the installation, ensure the culvert or culverts are large enough to handle the flow. When properly installed there is no need for steamers in the spring to open the culvert. 

The Beaver Proof Add On can be manufactured to fit culverts that are sloped such as the ones that are installed in highways and most M.D. roads. When used in reservoirs or dams, the water level can be maintained by installing a control gate on the outlet end.

The Beaver Proof Add On is permanent. With proper installation it will provide you with years of continuous protection from the damage and destruction the beavers cause
